Tipo de ítem: Ítem , Conocimiento de los estudiantes de la facultad de odontología de la Universidad Santo Tomás sobre interpretación del hemograma en la atención odontológica (2025)(Universidad Santo Tomás, 2026-06-12) Martínez Haro, Jaider José; Navarro Manzano, Nairon; Lanzziano Duarte, Darwin Jhoseht; Bayona Palacio, Santiago; Jaime Ospina, Gustavo Andrés; Picón Peña, Jairo Fernando; Universidad Santo TomásBackground: The complete blood count (CBC) -is one of the most common laboratory tests used to assess patients’ overall health and identify hematological abnormalities that may be relevant to dental care. Accurate interpretation of these results allows for the identification of conditions such as anemia, infections, or coagulation disorders that could pose risks during clinical procedures. For this reason, it is important for dental students to develop the skills necessary to accurately analyze this test and apply it to clinical practice. Method: A cross-sectional observational study was conducted; data were collected via an online questionnaire containing 22 questions. Subsequently, the data were analyzed using descriptive statistics and bivariate analysis to determine the participants’ level of knowledge. Results: 54% of undergraduate students showed a low level of knowledge regarding hemogram interpretation, whereas 45% of postgraduate students demonstrated an intermediate level. Although postgraduate students obtained slightly higher percentages in the intermediate and high knowledge levels, no statistically significant differences were identified between the two groups. Likewise, no significant association was found between the level of knowledge and the sociodemographic variables evaluated. Conclusion: Understanding blood tests is closely linked to the educational level of dental students, demonstrating that, despite knowing the fundamental values, they have difficulty interpreting them clinically, which could influence the decisions they make and patient safety.Tipo de ítem: Ítem , Comparación indirecta de la rugosidad superficial relativa en resina Forma Ultradent tras la aplicación de dos sistemas de pulido: estudio in vitro.(Universidad Santo Tomás, 2026-06-03) Correa Ordoñez, Luis Alejandro; Rico Solano, Juan David; Hernández Carvajal, Mariana Stefannia; Ariza Sedano, Juan José; Universidad Santo TomasIntroduction: The finishing and polishing of composite resins is a fundamental step in restorative dentistry, as it directly influences the surface roughness, color stability, and clinical durability of restorations. Objective: To compare the surface roughness obtained after applying two polishing systems, Sof-Lex (3M ESPE) and Shofu (Super-Snap Single), to Forma composite resin (Ultradent). Methodology: An in vitro experimental study was conducted using 35 standardized resin blocks (10 mm in diameter and 2 mm in height), divided into three groups: 15 samples polished with Sof-Lex discs, 15 with Shofu discs, and 5 unpolished (control group). The surfaces were analyzed using scanning electron microscopy (SEM), and the micrographs were processed with ImageJ software to obtain surface roughness values (Ra) expressed in Gray Level Units (GLU). Statistical analysis included descriptive and bivariate statistics with one-way ANOVA and a Bonferroni post hoc test (p < 0.05). Results: The unpolished group had the highest surface roughness values (9186.23 ± 2345.92 GLU), while the polished groups showed lower values: Sof-Lex (5413.86 ± 1210.93 GLU) and Shofu (4323.95 ± 1304.94 GLU). The ANOVA analysis revealed significant differences between the Sof-Lex group and the control group, and between the Shofu group and the control group (p < 0.001); differences were found between the control group and both polishing systems, but not between Sof-Lex and Shofu (p > 0.05). Conclusions: Both polishing systems significantly reduce the surface roughness of composite resin compared to unpolished surfaces; however, no statistically significant superiority was demonstrated between Sof-Lex and Shofu, so both can be considered clinically effective for finishing composite resin restorations.Tipo de ítem: Ítem , Autopercepción de enfermedad periodontal en personal militar de la Quinta Brigada Batallón De Infantería Capitán Antonio Ricaurte(Universidad Santo Tomás, 2026-06-03) Sánchez León, Geovanna Andrea; Sanabria Estupiñán, Kevyn Camilo; Pinto Estebes, Liceht Karina; Amaya Bautista , Claudia; Universidad Santo TomásBackground: Periodontal disease is a chronic inflammatory disease that affects the supporting tissues of teeth and can lead to tooth loss if not treated promptly. Its relevance lies in its high prevalence and its association with systemic diseases such as diabetes, cardiovascular disease, and Alzheimer's. Military personnel are subject to specific risk factors such as chronic stress, tobacco use, irregular work schedules, and difficulty accessing dental care, which could increase their vulnerability to periodontal disease. Objective: To determine self-perceptions of periodontal disease among military personnel of the Fifth Brigade, Captain Antonio Ricaurte Infantry Battalion (BIRIC) in Bucaramanga during the first half of 2025. Methodology: A cross-sectional, descriptive, observational study was conducted in a sample of 80 active military personnel, selected from a population of 100, belonging to the Fifth Brigade, Second Division, Antonio Ricaurte Battalion in Bucaramanga. A questionnaire was administered that included sociodemographic variables, hygiene habits, tobacco use, stress level, oral care knowledge and practices, and perception of periodontal disease. Data were entered in duplicate. Frequencies and proportions were calculated for qualitative variables and measures of central tendency for quantitative variables. Results: The median age was 23 (IQR 20-25); 85% were men; no history of systemic disease was reported. Regarding self-perception, 16.3% reported gingival bleeding when brushing, 7.5% reported inflammation, 11.2% reported frequent halitosis, 7.5% reported gingival recession, 3.7% reported tooth mobility, and 8.8% reported pain when chewing. Conclusions: Self-perception of periodontal disease in this military population revealed significant vulnerability, reflected in the presence of perceived symptoms such as gingival bleeding, halitosis, and recession, accompanied by poor use of oral hygiene products and poor attendance at dental checkups. The need to design and implement oral health education programs, prevention strategies, and timely access to dental services tailored to the military context is highlighted.Tipo de ítem: Ítem , Diseño y validación de material educativo sobre avulsión de dientes permanentes dirigido a estudiantes de último semestre de Odontología.(Universidad Santo Tomás, 2026-06-02) Porras Duran, Camilo Andres; Lesmez Moreno, Laura Cristina; Colmenares Salazar, Paula Andrea; Manosalva, María Alejandra; Universidad Santo TomásDental avulsion is one of the most frequent traumatic injuries in dentistry, characterized by the complete expulsion of the tooth from its socket. This condition mainly affects children and adolescents, compromising aesthetics, function, and patients’ quality of life. Immediate and adequate care is essential to preserve the tooth; however, several studies reveal gaps in dental students’ knowledge regarding the timely management of these emergencies. In this context, the need to strengthen academic training through specific educational resources is recognized. The objective of this study is to design and validate a digital educational material on the management of dental avulsion in permanent teeth, aimed at tenth-semester Dentistry students at Universidad Santo Tomás. The method corresponds to a diagnostic technology evaluation that includes face and content validation of the educational material. The study population consists of tenth-semester students and faculty specialists in endodontics and pediatric dentistry. Data collection is carried out through a structured questionnaire in Google Forms, based on the PAHO guidelines for the evaluation of educational materials. The information is analyzed using descriptive statistics according to the nature of the variables. The results show the participation of 31 individuals, including students and faculty, with a predominance of females and a median age of 24 years. The best-rated variables are comprehension (83.9%), relevance (83.9%), and clarity (77.4%), while form (67.7%) and accuracy (64.5%) receive moderate ratings. Overall, the material is considered relevant, understandable, and useful for the educational process. It is concluded that the validated educational material strengthens students’ knowledge about dental avulsion and constitutes an academic resource applicable in clinical practice. The validation highlights the importance of adjusting aspects of form and accuracy to optimize future versions and ensure pedagogical quality.Tipo de ítem: Ítem , Comparación de dos marcas comerciales de postes de fibra de vidrio realizados sobre premolares examinando la resistencia mecánica a la fractura(Universidad Santo Tomás, 2026-05-25) Andrade Florez, Marcela Alejandra; Sarquez Parra, Diego Alejandro; Ariza Sedano, Juan Jose; Universidad Santo TomasThis study aimed to evaluate and compare the mechanical fracture resistance of two different brands of fiberglass posts used in the dental clinic of Santo Tomás University, Floridablanca campus. Fiberglass posts play an important role in the rehabilitation of endodontically treated teeth because they provide support, stability, and proper distribution of occlusal forces, helping to preserve the remaining dental structure and improve the longevity of restorations. An in vitro experimental study was conducted using a sample of 60 maxillary first premolars obtained from the university’s tooth bank. The specimens were divided into three groups: 20 teeth restored with the first brand of fiberglass posts, 20 restored with the second brand, and 20 teeth assigned to the control group. All teeth underwent endodontic treatment followed by the corresponding rehabilitation procedure. Subsequently, the samples were subjected to vertical compressive load tests to determine their fracture resistance and compare the mechanical performance of the different groups. The results demonstrated the behavior of the fiberglass post groups under vertical compressive forces. However, statistical analysis revealed that none of the observed effects were statistically significant. These findings indicate that there is insufficient evidence to conclude that either brand has a significant influence on peak load capacity or fracture resistance when compared with the control group. Therefore, under the conditions of this study, both fiberglass post systems exhibited similar mechanical performance. In conclusion, the two evaluated brands of fiberglass posts showed comparable resistance to vertical compressive forces and fracture. Since no significant differences were found between them, the selection of a specific brand should not be based solely on mechanical resistance. Instead, clinicians should consider other relevant factors, including the patient’s clinical needs, treatment objectives, handling characteristics, availability, and expected conditions of use. Careful assessment of these factors will help dental professionals choose the most appropriate fiberglass post system and achieve optimal outcomes in the rehabilitation of endodontically treated teeth.Tipo de ítem: Ítem , Percepción de ansiedad, depresión y estrés a través del DASS-21 en jóvenes Universitarios de la División Ciencias de la salud USTA(Universidad Santo Tomás, 2026-05-15) Alarcón Cardozo, Karen Dayana; Diaz Mercado, Rene Alexander; Vargas Montaña, Beatriz; Peñaranda Carreño, Oscar Andres; Castellanos Domínguez, Yeny Zulay; Universidad Santo TomásIntroduction: Mental disorders affect thoughts, moods, and behaviors. Lack of timely diagnosis can lead to short- and/or long-term changes. In the academic field, students face situations such as exams, assignments, and personal problems, which makes them more vulnerable to these disorders. Objective: To evaluate the perception of mental health according to the DASS-21 scale in students from the Health Sciences Division of the Santo Tomás University in Bucaramanga. Materials and methods: A cross-sectional, analytical, observational study with 231 participants using randomized stratified sampling. Students from the first to tenth semester were included. The DASS-21 questionnaire was used to assess depression, anxiety, and stress, among other sociodemographic variables, health habits, academic, family, and social networks. Univariate statistical analysis was performed using frequencies with percentages such as median with interquartile range (IQR), bivariate analysis with Chi2, Fisher's exact test, and ANOVA. The study received favorable ethical approval from the institutional ethics committee. Results: A higher participation of women (67.10%), with a median age of 20 years (IQR 17-22), from the Faculty of Dentistry (65.92%) of 6th semester (16.59%) was found. In addition, 47.09% did not have depression, anxiety with a moderate level in 24.66% and 52.91% reported not presenting stress in the survey. Variables such as hours of sleep, study hours, cigarette consumption and use of the TikTok social network were identified as statistically associated with the presence of depression, anxiety and stress in students with p values ≤ 0.05. Conclusions: Students are vulnerable to mental health problems due to academic load, lack of free time and insufficient sleep. These conditions lead them to adopt harmful habits, although satisfactory in the short term.Tipo de ítem: Ítem , Evaluacion del conocimiento de los estudiantes de la universidad sobre el uso de medicacion intraconducto(Universidad Santo Tomás, 2026-05-15) Celedon Amaya, Rafael David; Piedrahita Saurith, Natalia Andrea; Orozco Gamez, Rafael David; Carrascal Quintero, Alvaro Alexander; Manosalva Estrada , Maria Alejandra; Universidad Santo TomasIntroduction: Endodontic treatment seeks to preserve teeth affected by dental caries, trauma, or periodontal disease. Nevertheless, the complex anatomy of the root canal system and the persistence of microorganisms limit its success. In this context, intracanal medication represents a fundamental adjunct to disinfection, aiming to reduce resistant bacteria and prevent reinfections. Objective: To evaluate the level of knowledge among sixth- to ninth-semester students of the Faculty of Dentistry at Universidad Santo Tomás, Bucaramanga, regarding the use of intracanal medication. Methodology: An analytical cross-sectional study was conducted with 139 students selected through stratified probabilistic sampling. A previously validated questionnaire was administered, consisting of twenty questions distributed across four domains: characteristics and mechanisms of action, objectives, diagnostic indications, and types of medicaments. Statistical analysis included Chi-square tests and Fisher’s Exact Test, with a significance level set at p<0.05. Results: More than half of the students demonstrated an intermediate level of knowledge (63.6%). No high levels of knowledge were recorded in the domains of objectives or diagnostic indications, while only 10% achieved a high level in the domain of types of medicaments. Students in advanced semesters showed a tendency toward better performance; however, the difference was not statistically significant. Conclusions: The findings highlight significant gaps in training related to intracanal medication, which may compromise clinical success and the prognosis of endodontic treatments. It is recommended to reinforce both theoretical and practical content in this area within the curriculum, to ensure comprehensive preparation of future dentists and to optimize therapeutic outcomes.Tipo de ítem: Ítem , Calidad de vida relacionada con la salud oral en pacientes con hiposalivación y/o disfagia en la Clínica de Adulto Mayor en la Universidad Santo Tomás(Universidad Santo Tomás, 2026-05-12) Galviz Pitre, Adriana Sofía; Barbosa Cervantes, Gessireth Carolina; Vargas Botero, Valentina; Martínez López, Carmen Alodia; Aranzazu Moya, Gloria Cristina; Universidad Santo TomásIntroduction: The quality of life related to oral health constitutes an essential component of the overall well-being of older adults, as it reflects how oral conditions affect basic functions such as eating, communication, autonomy, and social interaction. Alterations such as hyposalivation, which reduces oral lubrication and hinders physiological processes, and dysphagia, which compromises swallowing and increases the risk of malnutrition, dehydration, and aspiration, generate an impact that transcends the biological sphere and also affects psychological and social aspects. Objective: To determine the relationship between the quality of life related to oral health and the disorders of hyposalivation and dysphagia in older adults treated at the Elderly Clinic of the Universidad Santo Tomás during the first semester of 2025. Materials and methods: An observational analytical case-control study was conducted with 83 older adults, classified according to their scores on the OHIP-14 questionnaire. Hyposalivation was assessed through the measurement of unstimulated salivary flow over five minutes, categorized as normal (>0.25 ml/min), low (0.1–0.25 ml/min), and very low (<0.1 ml/min), while dysphagia was evaluated with the Eating Assessment Tool-10 (EAT-10), considering a score ≥3 as an indicator of clinical risk. Results: The sample included 31 cases (37.3%) with poor quality of life and 52 controls (62.7%) with good quality of life. No significant association was found between hyposalivation and quality of life (p = 0.835), but a significant relationship was observed between dysphagia and quality of life (p < 0.001), being more prevalent in the cases (57.9%) than in the controls (30.7%). Conclusion: Isolated hyposalivation does not behave as a determining factor, whereas dysphagia is consolidated as a key predictor of deterioration in quality of life, highlighting the need for a comprehensive approach in geriatric dental care.Tipo de ítem: Ítem , El entorno familiar y su vinculación con el rendimiento académico en estudiantes de Odontología de la Universidad Santo Tomás de Bucaramanga(Universidad Santo Tomás, 2026-05-11) Cifuentes Ravelo, Natalia; Rodríguez García, Ana isabella; Reatiga Ruiz, Karen Nicole; Almario barrera, Andrea Johanna; Universidad Santo TomásIntroduction: The academic performance of university students is an essential factor in their professional training, especially in high-demand disciplines such as Dentistry. Objective: To analyze how the family environment influences the academic performance of Dentistry students at the Universidad Santo Tomás in Bucaramanga. Materials and Methods: An analytical cross- sectional study was conducted with a stratified probabilistic sample of 132 students, from the second to the tenth semester, selected from a total population of 782 enrolled in the first academic period of 2025. The information was obtained through a validated questionnaire that included data on sociodemographic aspects, family characteristics, and academic performance. For the statistical analysis, univariate and bivariate tests were applied, considering a p-value ≤ 0.05 as statistically significant. Results: Emotional and financial support from the family environment was significantly associated with better academic performance. Conclusions: The family environment played a fundamental role in the educational process of Dentistry students, highlighting the importance of strengthening these bonds to improve academic outcomes.Tipo de ítem: Ítem , Calidad de vida en pacientes con maloclusiones sagitales clase III sometidos a cirugía ortognática. Una revisión sistemática(Universidad Santo Tomás, 2026-04-06) Castro Castellanos, Yuri Andrea; Rodríguez Santiago, Shelsy Nicol; Vega Acevedo, Luz Esnaira; Diaz Calderón, Yhojann Fabricio; Sánchez Gutiérrez, Héctor Mauricio; Universidad Santo TomásIntroduction. Class III sagittal malocclusions are frequent and cause aesthetic, functional, and psychosocial repercussions that deteriorate quality of life. In adults, orthognathic surgery is the treatment of choice because it corrects skeletal discrepancies and harmonizes the facial profile; however, published results on satisfaction and well-being are variable, which justifies a rigorous synthesis. Objective. To determine the impact of orthognathic surgery on the quality of life of adults with Class III malocclusion through a systematic review of literature published between 2020 and 2024. Methods. Articles were searched in PubMed, Scopus, Web of Science, and ScienceDirect. Observational studies in English or Spanish, full-text, with non-syndromic adults operated for Class III were included. Predefined selection criteria were applied, methodological quality was assessed with the Spanish-validated STROBE checklist, and study design, sample characteristics, quality-of-life instruments (OQLQ, OHIP-14, FACE-Q, PIDAQ), follow-up times, and main outcomes were extracted. Results. Of 96 records identified, 15 met the criteria. Clearly significant improvements were observed from the third postoperative month, consolidating at 6–12 months. The most benefited domains were facial aesthetics, self-esteem, oral function, and social interaction, while awareness of deformity showed less recovery. Forty percent of the studies had high methodological quality, and 60% medium quality. The heterogeneity of instruments and follow-ups hindered direct comparisons. Conclusion. Evidence from 2020–2024 indicates that orthognathic surgery for Class III consistently improves perceived quality of life, with the greatest effect in aesthetic, psychosocial, and functional dimensions, and benefits consolidating from 6–12 months onward.Tipo de ítem: Ítem , Diseño asistido por computadora de un macromodelo para facilitar el aprendizaje del efecto ferrule desde la mirada de actores claves(Universidad Santo Tomás, 2026-02-21) García Quiroga, Karen Melissa; Gámez Ardila, Paula Liseth; Castro Martínez, María Alejandra; Guerrero Torres, Mario Andrés; Universidad Santo TomásIntroduction: The ferrule effect is a fundamental principle in restorative dentistry because it strengthens endodontically treated teeth, improves force distribution, and increases the longevity of restorations. At Santo Tomás University, a difficulty in teaching this concept has been identified because the images presented in the classroom do not replace hands-on practice, which limits students' understanding. In view of this problem, the design of a macro model using CAD-CAM technology is proposed to enable more practical and meaningful learning. Objective: To design and create a macro model that facilitates learning about the ferrule effect and meets the needs of dentists in training, based on the opinions of experts and users from the Faculty of Dentistry at Santo Tomás University, 2025. Materials and methods: The study is qualitative, action research- based, and focuses on the systematization of experiences. Specialist teachers and undergraduate dentistry students participate through focus groups and semi-structured interviews. The intervention consists of the participatory design of a macro model based on a literature review and software modeling, considering variables such as understanding of the concept, pedagogical perception, and usefulness of the resource. The research is classified as risk-free, as it respects the confidentiality of the participants and has informed consent. Results: The findings show that the teaching of the ferrule effect is perceived as fragmented and rote, creating a gap between theory and practice. The macro model designed is recognized as an innovative tool that facilitates three- dimensional visualization of the concept, promotes interdisciplinarity between rehabilitation, endodontics, and periodontics, and strengthens the transition from theoretical knowledge to clinical practice. Conclusion: The macromodel is an effective pedagogical tool that integrates theory and practice, optimizes understanding of the ferrule effect, and contributes to improving preclinical training in oral rehabilitation, supporting its value as a teaching resource in dentistry.Tipo de ítem: Ítem , Efectividad del propóleo como tratamiento para la gingivitis y la periodontitis: una revisión sistemática(Universidad Santo Tomás, 2026-02-12) Roa Rodríguez, María José; Cáceres Diaz, Valentina; Pinto Gonzáles, Valentina; Vera Otálora, Lyant Steven; Hernández Hincapié, Hernán Guillermo; Universidad Santo TomasIntroduction: Propolis is a natural substance produced by bees, with antimicrobial, anti-inflammatory, and antioxidant properties. It emerges as a promising adjuvant in the management of periodontal diseases, representing a natural alternative that reduces adverse effects of conventional treatments with comparable effectiveness. Objective: To analyze the effectiveness of propolis for the treatment of gingivitis and periodontitis reported in the scientific literature between 2017 and 2024. Materials and Methods: A systematic review of the literature published between 2017 and 2024 in English, Spanish, Portuguese, and Mandarin was conducted. Clinical trials and quasi-experimental studies from PubMed, Scopus, and Web of Science databases that evaluated the effectiveness of propolis considering clinical parameters of plaque index (PI), gingival index (IG), probing pocket depth (PPD), bleeding on probing (BOP), and clinical attachment level (CAL) were included, excluding articles without full text. Univariate statistical analysis was performed, the reporting quality of clinical trials was assessed with CONSORT 2010, and bias evaluation was conducted with the Cochrane ROB2 tool. Results: Propolis demonstrated effectiveness as an adjuvant treatment in periodontal therapy, with significant improvements in clinical parameters. Studies reported substantial reductions in PI, IG, PPD, BOP, and CAL. Conclusions: The efficacy of propolis was established through clinical parameters such as BOP, PPD, CAL, IG, and PI. Its effectiveness in the management of gingivitis and periodontitis was evidenced, especially in the latter, with efficacy comparable and in some cases superior to reference agents such as chlorhexidine. The evaluation with CONSORT 2010 showed acceptable but not optimal quality, recommending improvements in future research. The bias assessment with RoB 2 revealed considerable biases in domains such as randomization, measurement, and selection of results, so the findings should be interpreted with caution.Tipo de ítem: Ítem , Porphyromonas gingivalis y enfermedad de Alzheimer: revisión sistemática de estudios preclínicos(Universidad Santo Tomás, 2026-01-15) Granados Correa, Juan Pablo; Sepúlveda Jácome, Valeria Juliana; Rodríguez Riaño, Meiby Syliana; Riviera Giraldo, Loren Dayana; Hernández Hincapie, Hernán Guillermo; Universidad Santo TomásIntroduction: Oral infection with Porphyromonas gingivalis (P. gingivalis) has been associated with neuroinflammation in Alzheimer's disease (AD), mediated through systemic bacteremia and bacterial proteases that disrupt cerebral proteins. Emerging evidence suggests this periodontal pathogen may influence AD pathogenesis via chronic inflammation, host immune responses, and blood-brain barrier compromise. Objective: to evaluate the effects of P. gingivalis in preclinical AD models by assessing cognitive impairment, inflammatory markers, amyloid-beta metabolism, and histopathological alterations. Materials and Methods: we conducted a systematic review of 11 preclinical studies (2015-2024) sourced from PubMed, Scopus, and Dentistry & Oral Science Source. The analysis included murine models infected with P. gingivalis through oral inoculation, intracerebral injections, or bacterial lipopolysaccharide (LPS) exposure. Results: experimental models employed various infection methods, including oral inoculation, intracranial administration, and LPS exposure. Investigations revealed significant CNS impacts, including neuroinflammatory responses, microglial activation, β-amyloid aggregation, and tau protein phosphorylation. Behavioral assessments (Morris water maze, Y-maze, passive avoidance tests) demonstrated measurable cognitive deficits. Notably, P. gingivalis and its virulence factors were found to breach the blood-brain barrier, triggering proinflammatory cytokine release and promoting amyloid plaque deposition. Conclusions: these findings support the hypothesis that chronic P. gingivalis infection and associated periodontitis may accelerate AD neuropathology through sustained neuroinflammation. The collective evidence underscores the potential importance of periodontal disease management as a modifiable risk factor in Alzheimer's disease progression.Tipo de ítem: Ítem , Asociación entre la condición protésica y la salud mental de los adultos mayores que asisten a los “Centros Vida” de Bucaramanga durante el primer semestre del año 2025(Universidad Santo Tomás, 2025-12-09) Vásquez Velasco, Danna Valentina; Medina Rojas, Karielen Yulieth; Montaño Santiago, Laurin Vanessa; Torrado Ortiz, María Fernanda; Picón Peña, Jairo Fernando; Universidad Santo TomásIntroduction: Oral health not only reflects a good appearance but also contributes to well-being and quality of life. In older adults, tooth loss or the use of poorly maintained dentures can cause discomfort, insecurity, and negatively impact their emotional and social well-being. Objective: To establish the relationship between prosthetic condition and mental health in older adults attending the “Centros Vida” of Bucaramanga during the first semester of 2025. Materials and methods: An analytical cross-sectional study was conducted with older adults from the Centros Vida in Bucaramanga. A clinical evaluation was performed to assess the condition of their dental prostheses, and data about their environment were collected. Emotional well-being was assessed using the GHQ-12 questionnaire. The results were analyzed using statistical tests to examine the relationship between prosthetic condition and mental health. Results: Most of the older adults evaluated (mean age: 72 years; 60.6% women) belonged to middle socioeconomic strata. Edentulism was common, especially in the upper jaw. Many used conventional full dentures, though in poor condition. Psychological distress was more prevalent among individuals with deteriorated dentures or no teeth, particularly in stratum 1. Conclusions: A clear association was found between prosthetic condition and mental health in older adults. Edentulism and poorly maintained dentures were linked to greater psychological distress, whereas the use of functional prostheses was associated with higher self-esteem and overall well-being.Tipo de ítem: Ítem , Satisfacción de los pacientes atendidos en las clínicas odontológicas de la Universidad Santo Tomás: evaluación en el Centro Internacional de Especialistas(Universidad Santo Tomás, 2025-11-25) Delgado Angel, Gabriela; Garcia Ojeda, Silvia Natalia; Suarez Amaris, Valerin Cecilia; Salinas Navarro, Andrea Carolina; Castellanos Domínguez, Yeny Zulay; Universidad Santo TomásIntroduction: Understanding patient satisfaction in university dental clinics helps identify areas for improvement, enhancing both professional training and service quality in a modern institution such as the Centro Internacional de Especialistas (CIE). Objective: To assess the level of satisfaction among patients treated at the dental clinics of Universidad Santo Tomás, CIE campus. Methodology: An analytical cross-sectional study was conducted in 2025 with patients selected through convenience sampling. A virtual survey designed in Google Forms included sociodemographic and satisfaction variables. Data were analyzed using STATA 14 through univariate and bivariate analyses, evaluating dimensions such as quality of information, patient care, accessibility, privacy, facilities, equipment, treatment outcomes, waiting time, costs, and service hours. Results: A total of 279 users participated, predominantly male (50.9%), with a median age of 45.1 years and mostly from socioeconomic stratum two (44.09%). The main reasons for consultation were dental check-ups (59.86%), aesthetics (31.9%), and emergencies (8.24%). More than 95% rated the care received, information provided, privacy, facilities, and dental equipment as “good,” reflecting high levels of satisfaction. Treatment cost showed the greatest dissatisfaction, with only 73.5% rating it as “fair” or “poor.” No significant association was found between satisfaction and sociodemographic variables (p>0.05). Conclusion: Participants reported high satisfaction levels across most evaluated dimensions, particularly in patient care, information, and infrastructure. Treatment costs had the lowest acceptance, emphasizing the importance of economic accessibility to enhance service perception. The findings highlight the need to sustain quality of care while developing strategies that balance sustainability and affordability.Tipo de ítem: Ítem , Evaluación ex vivo de la eficacia de la N-Acetilcisteína como irrigante endodóntico frente a Enterococcus faecalis: estudio piloto(Universidad Santo Tomás, 2025-11-11) García Barragán, Laura Yanith; Pérez Quiroga, Yary Hasbleidy; Calderón Cadena, Santos Sarid; Manosalva Estrada, Maria Alejandra; Herrera Sandoval, Laura Viviana; Universidad Santo TomásIntroduction: Enterococcus faecalis is a Gram-positive coccus associated with persistent infections and therapeutic failures due to its ability to survive in root canal under extreme conditions, complicating disinfection during endodontic treatment. Although 5.25% sodium hypochlorite (NaClO) is the most commonly used irrigant, its cytotoxicity and adverse effects have prompted the search for alternatives. Objective: To evaluate the ex vivo efficacy of N-acetylcysteine as an endodontic irrigant against E. faecalis in a tooth model. Materials and methods: A pilot study was conducted using 45 human teeth obtained from the Santo Tomás University tooth bank, including incisors, canines, and premolars. These were selected and randomly distributed into the following groups: N-acetylcysteine 100 mg (12 teeth), N-acetylcysteine 200 mg (9 teeth), 5.25% sodium hypochlorite (13 teeth), and a control group with 0.85% saline solution (11 teeth). The teeth were sterilized, instrumented, and contaminated with E. faecalis for 30 days. Subsequently, each group was irrigated with 5 mL of the corresponding irrigating substance for 3 minutes, followed by inactivation and canal drying. Colony-forming units (CFUs) were then counted using serial dilutions and Plate Count agar plating. Selected samples were analyzed via scanning electron microscopy (SEM) to evaluate morphological changes in the biofilm. Results: Sodium hypochlorite (NaClO) achieved a 100% reduction in microbial load, followed by NAC 200mg (66.6%) and finally NAC 100mg (49.6%). Microphotographs confirmed that sodium hypochlorite effectively cleared the canal of E. faecalis biofilm .Conclusions: N-Acetylcysteine has the ability to inhibit the growth of E. faecalis and could serve as an alternative irrigating solution for disinfecting the root canal during endodontic treatment. However, its efficacy is lower than that of 5.25% sodium hypochlorite.Tipo de ítem: Ítem , Evaluación de presencia de microcracks en dientes de único conducto utilizando 2 tipos de instrumentación rotatoria. Estudio ex vivo(Universidad Santo Tomás, 2025-11-11) Ardila Jerez, Laura Alejandra; Arredondo Galezo, Angela Sofia; Manosalva Estrada, María AlejandraProblem: Although microcrack formation is a frequent phenomenon that can compromise dental integrity and increase the risk of vertical fractures, there is no consensus in the literature on the predisposing factors or which system is safer. Objective: To evaluate the formation of microcracks during endodontic instrumentation in uniradicular teeth, comparing the ProTaper Next and Wave One Gold rotary systems. The hypothesis is that the choice of instrumentation system significantly influences microcrack formation. Methods: 43 uniradicular teeth were used, divided into three groups: Wave One Gold, ProTaper Next and a control group. After instrumentation, the presence of microcracks was evaluated by microscopic inspection. The variables analyzed included the instrumentation system, dental anatomy and the operator. Results: It was demonstrated that 62.79% of the teeth did not present microcracks. A statistically significant association was found between the instrumentation system and microcrack formation (p = 0.021), with the control group being free of microcracks. In addition, no significant associations were observed with dental anatomy or operator. Conclusion: Microcrack formation is not inevitable, but is influenced by the instrumentation system used. The instrumentation systems evaluated showed significant differences in relation to the incidence of microcracks. A greater presence of these phenomena was determined with the Wave One Gold system. It is important for the clinician to select systems that minimize dentin damage and preserve the structural integrity of the tooth during endodontic treatment.Tipo de ítem: Ítem , Resistencia a la fractura de dos marcas comerciales de acrilico sometidos a una sustancia limpiadora(Universidad Santo Tomás, 2025-10-29) Alza Rodriguez, Jairo Alfonso; Ramirez Carvajal, German Andrés; Traslaviña Duarte, Adrián Felipe; Picon Peña, Jairo Fernando; Universidad Santo TomásIntroduction: Heat-cured acrylic prostheses are used in dentistry to restore dental function and aesthetics, but their strength can be affected by mechanical forces and disinfecting agents. Therefore, the present study analyzes the strength and structural alterations of acrylic subjected to different immersion conditions. Objective: To evaluate the fracture resistance of two heat-cured acrylics (acrylic A and acrylic B) and to analyze whether exposure to disinfectants affects their mechanical properties. Materials and methods: An in vitro experimental study was carried out where 60 samples of heat-cured acrylic (30 of each brand) (acrylic A and acrylic B were prepared, dividing them into three groups: without exposure, immersed in distilled water and in cleaning substance. Their flexural and impact strength were evaluated using universal testing equipment (MTS), and a comparative statistical analysis was performed on each of the samples of the two types of acrylics evaluated. Results: Acrylic A was found to have greater structural strength than acrylic B, with a median peak load of 0.318 kN versus 0.284 kN. No statistically significant differences were observed between samples exposed to disinfectants, although cleaning substance showed a slight tendency toward improved material strength. Conclusion: Acrylic A exhibited greater structural stability compared to acrylic B. Exposure to cleaning substance did not significantly affect the strength of acrylics in the short term, but additional studies are needed to evaluate their long-term impact, as disinfecting agents directly influence their durability. This will allow for the establishment of optimal maintenance methods to extend their lifespan.Tipo de ítem: Ítem , Relación del autoestima con el edentulismo y estado protésico en adultos mayores que asisten en el centro vida "años maravillosos" en Bucaramanga(Universidad Santo Tomás, 2025-09-11) Báez Caballero, Paula Valentina; Cerón Ramírez, María Fernanda; Ramírez Ruiz, Laura Nathalia; Rueda Sierra, Daniela Fernanda; Picón Peña, Jairo Fernando; Orgulloso Bautista, Claudia AlejandraIntroduction: Edentulism, or the partial or total loss of teeth, is a prevalent condition in older adults that can affect both masticatory function and self-esteem, as well as mental health. Objective: To analyze the relationship between self-esteem, edentulism, and prosthetic status in older adults attending the Centro Vida Años Maravillosos in the Real de Minas branch in 2025. Materials and methods: An analytical, cross-sectional observational study with a sample of 106 older adults. Each participant signed informed consent as part of the inclusion criteria. Self-esteem was measured using the Rosenberg Scale with sociodemographic and clinical aspects. A univariate analysis was performed using frequencies with percentages as the median and standard deviation (SD). A bivariate analysis was performed using Chi2, Fisher's exact test, and Kruskall-Wallis tests with p values <0.05. The study was classified as a low-risk study since it consists of a record of sensitive data that covers a psychological topic. Results: It was found that 50% of the participants had low self-esteem, while 43.3% had a medium level and only 5.6% had high self-esteem. In addition, 59.43% used prostheses in the upper jaw and 28.30% in the lower jaw, although 42.45% required a prosthesis in the lower jaw and did not have one. Statistical analysis did not show a significant relationship between denture use and self-esteem, although low-income participants tended to have lower self-esteem (p=0.035). Conclusion: These findings suggest that, although tooth loss impacts quality of life, other factors such as socioeconomic status may have a greater influence on older adults' self-esteem. It is important to provide support as they cope with tooth loss and a significant change in lifestyle.Tipo de ítem: Ítem , Revisión sistemática para el desarrollo de un manual odontológico en pacientes con terapia antineoplásica(Universidad Santo Tomás, 2025-07-29) Montañez Flórez, Tatiana Alexandra; García Hernández, Manuela; Restrepo Vásquez, María Paula; León Gómez, Juan David; Pino Velez, CarolinaIntroduction: Dental care for patients undergoing antineoplastic treatment is essential to prevent and manage oral complications that may impact quality of life and continuity of cancer therapy. Antineoplastic therapy is associated with several adverse effects, such as mucositis, xerostomia, osteoradionecrosis, and odontogenic infections, highlighting the need for a multidisciplinary approach and standardized protocols. Objective: This study aimed to conduct a systematic review of the evidence regarding dental management before, during, and after antineoplastic therapy, as presented in clinical guidelines and protocols, for the development of a patient orientation manual for those undergoing such therapy. Methods: A systematic review of guidelines and protocols published between 2017 and 2024 was carried out in Spanish, English, and Portuguese. The search was conducted in the Scopus, PubMed, and Web of Science databases using a PICO question and platform-specific search equations. Documents addressing dental management in all three treatment phases—before, during, and after—were included. The methodological quality of the guidelines was assessed using the AGREE II tool. Statistical analysis was performed with Stata v14.0 and Microsoft Excel 365, using univariate analysis for qualitative variables and measures of central tendency and dispersion for quantitative variables. Results: A total of 95 documents were identified. After applying the selection criteria, 12 clinical guidelines were included. Among them, 2 addressed dental care before treatment, 2 during, 2 after, 4 during and after, and 2 across all three phases. The average methodological quality assessed with AGREE II was 69.7 ± 0.98. Most of the reviewed studies reported a high prevalence of complications such as xerostomia, mucositis, and osteoradionecrosis in patients receiving antineoplastic therapy. An orientation manual is proposed as a guide to improve clinical practice for dental students and practitioners, supporting clinical decision-making. Conclusion: Dental management of patients undergoing antineoplastic therapy requires a protocolized approach across all treatment phases—before, during, and after—to minimize complications and improve patients’ quality of life. These patients commonly experience oral complications including mucositis, xerostomia, osteoradionecrosis, dysgeusia, trismus, and tooth loss. Interdisciplinary coordination and patient education emerge as key strategies to optimize clinical outcomes. Teamwork and clearly defined protocols at each treatment stage enhance the quality of dental care provided.
