(Universidad Santo Tomás, 2026-07-29) Gómez Ardila, Daniel Alexander; Tarazona Amado, Juan Sebastian; Veru Leon, Maria Camilia; Rueda Martínez, Gabriela; Universidad Santo Tomás
This study aimed to analyze dental students' self-perception of ergonomic conditions and evaluate the postures they adopted during their clinical practice at Universidad Santo Tomás. The research addressed the relationship between ergonomics, working postures, and the risk of developing musculoskeletal disorders during clinical training by integrating students' perceptions with an objective assessment of their postures. A mixed-methods study with a sequential design was conducted. The qualitative component consisted of semi-structured interviews designed to explore students' self-perception of ergonomic conditions and the application of ergonomic principles in clinical practice. The quantitative component comprised a descriptive cross-sectional observational study in which photographic records were analyzed using Kinovea software and the Modified Dental Operator Posture Assessment Instrument (M-DOPAI) to objectively evaluate the postures adopted by the participants. The results showed a mean M-DOPAI score of 16.83 ± 1.58, with 91.67% of the students classified in the acceptable posture category and 8.33% in the compromised category. However, significant postural alterations were identified, particularly in anterior head and neck flexion and wrist flexion or extension, which are considered risk factors for the development of musculoskeletal disorders. Furthermore, the interviews revealed that although students recognize the importance of ergonomics, its application during clinical practice remains limited due to individual and environmental factors. In conclusion, the findings demonstrate the need to strengthen ergonomic education from the undergraduate level and to implement preventive, educational, and monitoring strategies that promote the adoption of appropriate working postures. These measures may contribute to the prevention of musculoskeletal disorders and improve the quality and safety of dental clinical practice.

Introduction: The loss of the dental papilla is a common problem that affects oral aesthetics and function. In recent years, the use of hyaluronic acid has been proposed as a minimally invasive therapeutic option for the reconstruction of the interdental papilla. However, scientific information related to this application is distributed across several databases, which complicates the identification of research trends, the most productive authors, and the evolution of knowledge in this field. Objective: Evaluate trends in scientific publications through a bibliometric study on the use of hyaluronic acid as a treatment for dental papilla reconstruction published between 2020 and 2025. Material and Methods: A bibliometric study was conducted. The search was carried out in the PubMed, Scopus, and Web of Science databases using a search equation related to hyaluronic acid and dental papilla. Articles published between January 2020 and July 2025 in English, Spanish, and Portuguese were included. The variables analyzed were authorship, institutional affiliation, scientific journal, country of publication, number of authors, language, and citations. Results: Initially, 298 studies were identified, of which 56 met the selection criteria. Most publications were found in the Scopus database (83.9%). The median number of authors per article was 5 (IQR 4–6). The number of female authors was higher among first authors (58.2%), while the number of male authors predominated among last authors (66.7%). Publications showed an increase in recent years, especially in 2024 and 2025. The journals with the highest number of publications included BMC Oral Health, Journal of Applied Cosmetology, and Journal of Indian Society of Periodontology. The median number of citations in Google Scholar was 2.5 (IQR 1.011.5). Conclusion: In recent years, scientific research on the use of hyaluronic acid in dental papilla reconstruction has increased, demonstrating a growing interest in minimally invasive regenerative treatments in cosmetic dentistry. However, research is still in the process of consolidation, and further clinical studies and international collaborations are needed to strengthen the available evidence.

(Universidad Santo Tomás, 2026-07-15) Carrillo Gutierrez, Isabela Andrea; Romero Gomez, Alexander; Almario Barrera, Andrea Johanna; Universidad Santo Tomás
Introduction. In Colombia, healthcare delivery—including oral health—faces several challenges that may be associated with structural factors such as resource management, system financing, and access to services. These conditions may differentially affect urban and rural communities, where social and economic contexts shape healthcare experiences. In this context, it is relevant to explore these dynamics in specific rural populations. Objective. To describe the perceptions and experiences regarding oral health among families residing in the rural area of Conejo, a district of Fonseca, La Guajira, in 2026. Materials and Methods. A qualitative study with an ethnographic approach was conducted. Participants were families selected through snowball sampling until theoretical saturation was reached. Semi-structured interviews were carried out in participants’ homes; these were audio-recorded, transcribed, and subsequently analyzed. Data triangulation was employed to enhance the study’s validity. The research adhered to ethical principles and was classified as minimal risk. Results. A total of 20 participants aged between 19 and 74 years were included. Findings indicate that oral health is primarily perceived as part of daily hygiene rather than as a preventive clinical practice. Toothbrushing was the most common practice, although variations in frequency and technique were observed, while the use of dental floss was limited. The use of home remedies, such as salt or baking soda, for oral care was also identified. Access to dental services is constrained by geographic and economic barriers, leading individuals to seek care mainly in the presence of pain. Additionally, sociocultural, economic, and geographic factors were found to influence oral health practices, highlighting the need to strengthen oral health education. Conclusions. Perceptions and practices related to oral health in this community are shaped by its social and economic context, which may limit the adoption of preventive measures. There is a need to implement educational strategies, improve access to dental services, and enhance quality of life while considering the specific characteristics of the rural setting.

(Universidad Santo Tomás, 2026-07-16) Cristancho Gonzalez, Zamy Sharol Micheel; Cruz Castiblanco, María Alejandra; Rojas Franco, Paula Alejandra; Rodriguez, Martha Juliana; Universidad Santo Tomas
Background: rest time is essential for the physical, cognitive, and behavioral development of children; however, disorders such as Obstructive Sleep Apnea (OSA) can affect sleep quality. Although polysomnography is considered the gold standard for diagnosing this condition, there are clinical screening tools such as the Pediatric Sleep Questionnaire (PSQ) that allow for the initial identification of associated symptoms. However, few studies have evaluated the usefulness of the PSQ in the pediatric population. Objective: to evaluate the diagnostic utility of the Colombian version of the Pediatric Sleep Questionnaire (PSQ) by relating its results to the presence of obstructive sleep apnea in pediatric patients treated during 2023–2024 at the Instituto Neumológico del Oriente in Bucaramanga. Methods: a diagnostic test evaluation study using secondary data was conducted. The study population consisted of 1,211 patients aged 2 to 12 years who were treated at the Instituto Neumológico del Oriente in Bucaramanga and presented symptoms related to OSA during 2023 and 2024. No sample size calculation or sampling technique was applied, as the entire population recorded in the database was included. Sociodemographic and clinical variables were analyzed, and the diagnostic performance of the questionnaire was assessed through statistical analyses, including sensitivity, specificity, and ROC curve calculations, using a cutoff point of 0.33. Results: a diagnostic test evaluation study was conducted using secondary data. The population consisted of 1,211 patients aged 2 to 12 years who were treated at the Instituto Neumológico del Oriente in Bucaramanga and presented symptoms related to obstructive sleep apnea (OSA) during 2023 and 2024. No sample size was calculated, nor was a sampling technique applied, as all available records in the database that met the inclusion criteria were included. The study analyzed sociodemographic and clinical variables, and the diagnostic performance of the questionnaire was evaluated through statistical analyses, including the calculation of sensitivity, specificity, and the ROC curve, using a cutoff point of 0.33. Conclusion: the PSQ showed a sensitivity of 51.0% and a specificity of 54.7%, with a discrimination capacity of 52.2%, indicating the presence of false positives when classifying some healthy patients as sick.

The presence of high concentrations of fluoride in drinking water poses a health risk, as overexposure to this element can cause dental and skeletal fluorosis. Even though fluoride strengthens teeth and eliminates microorganisms from plaque, finding ways to filter fluoride from water is primarily justified to prevent the pathologies. Objective: To evaluate the fluoride removal capacity of a homemade filter made from clinoptilolite zeolite to avoid the risk of toxicity from high fluoride consumption. Materials and methods: A quasi-experimental in vitro before-and-after study was conducted. Initially, six water samples from the Ojito spring and the Verdal aqueduct were analyzed, determining fluoride concentrations between 0.66 and 6.90 mg/L using CANW-VIS spectrophotometry. Very high fluoride concentrations (1.52–6.90 mg/L), harmful to health, were found in the Verdal water samples. In addition, three prototypes of household filters with varying zeolite thicknesses were designed and evaluated to reduce fluoride levels. Results: A non-detectable (N.D.) response for fluoride concentration was observed in 15 of the 18 tests. Furthermore, prototype 2 demonstrated stability throughout all six tests, maintaining final concentrations of 0 mg/L in all cases. Conclusion: The research revealed elevated fluoride levels in the water sources of Cepitá, associated with a potential risk of dental fluorosis. As a preventative alternative, household filters using clinoptilolite zeolite were designed, with the 2 cm prototype standing out for its greater effectiveness in fluoride removal. Moreover, the system proved to be an economical and viable option for rural communities.

Introduction: bruxism is a non-functional muscular activity associated with various factors such as stress and certain habits. Objective: to determine the relationship between self-perceived bruxism and cigarette consumption and other related substances in young adult students from the Health Sciences Division at Santo Tomás University. Methods: an observational, analytical, cross-sectional study was conducted with a sample of 203 students. Data were collected using the Self-Reported Bruxism Questionnaire (SRBQ) with a Likert-type scale (1: none to 5: a lot). Descriptive analysis was performed using frequencies and percentages, and bivariate analysis was conducted using Fisher’s exact test. For quantitative variables, Student’s t-test or Mann–Whitney U test were used according to data distribution. Statistical significance was set at p < 0.05. Results: most participants were female and primarily between 15 and 20 years old. A total of 71.4% of students reported not having self-perceived bruxism, and 70.4% reported no substance use. According to the Self-Reported Bruxism Questionnaire (SRBQ), 93.6% of participants were classified as without bruxism, 3.9% as probable bruxism, and 2.5% with bruxism. When comparing SRBQ results with self-perceived bruxism, greater agreement was observed among those who did not perceive themselves as having the condition, while discrepancies were found among those who did report it. Conclusion: when comparing self-perceived bruxism with questionnaire results, greater agreement was observed in students who did not present the condition. Additionally, no statistically significant association was found between self-perceived bruxism and habits related to cigarette consumption and other similar substances in the studied sample.

Introduction: oral health in children is a key pillar of overall well-being, mediated by a complex interaction of biological, social, and systemic factors. Among these, family functioning becomes a critical determinant, as it modulates hygiene habits and other preventive behaviors that influence the prevalence of dental caries. Objective: to determine the relationship between family functioning and the presence of cavitated dental caries in children aged 8 to 12 years treated at a health facility during 2025-2026. Method: a cross-sectional, analytical, observational study was conducted with a sample of 123 children. Sociodemographic information was collected, and after obtaining informed consent from the parents and assent from the children, the Family APGAR questionnaire was administered to assess family functioning. A clinical examination was also performed to identify the presence of cavitated caries. The analysis included descriptive statistics and bivariate analysis using the chi-square test, with estimation of prevalence ratios (PR). This study is considered low-risk and was approved and reviewed by an ethics committee. Results: a higher proportion of females (53.7%) and a predominance of socioeconomic stratum 3 (29.3%) were observed. The prevalence of cavitated caries was 55.3%, indicating a high frequency of the disease. In the study population (123 children), the majority of participants belonged to functional families (82.9%). Furthermore, caries was 46% more prevalent in children with family dysfunction than in those without this condition (PR=1.46; 95% CI: 1.18–1.80). Conclusion: family functioning significantly influences children's oral health; family dysfunction is associated with a higher probability of caries, highlighting the importance of preventive strategies that involve the family.

(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 Tomás
Background: 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.

(Universidad Santo Tomás, 2026-06-03) Correa Ordoñez, Luis Alejandro; Rico Solano, Juan David; Hernández Carvajal, Mariana Stefannia; Ariza Sedano, Juan José; Universidad Santo Tomas
Introduction: 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.

(Universidad Santo Tomás, 2026-06-03) Sánchez León, Geovanna Andrea; Sanabria Estupiñán, Kevyn Camilo; Pinto Estebes, Liceht Karina; Amaya Bautista , Claudia; Universidad Santo Tomás
Background: 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.

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 Tomas
This 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.

(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 Tomás
Introduction: 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.

(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 Tomas
Introduction: 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.

(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 Tomás
Introduction: 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.

Introduction. 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.

Introduction: 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.

Introduction: 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.
