The thermomechanical properties of nickel–titanium (NiTi) endodontic instruments are strongly influenced by their phase transformation temperatures, which determine their microstructural behaviour under clinical conditions. Objective. Objective: To evaluate and compare the phase transformation temperatures (Ms, Mf, As, and Af) and the thermal behaviour of three NiTi rotary systems (ProTaper Ultimate™, Rotate™, and Plex V™) using differential scanning calorimetry (DSC). Materials and Methods. An in vitro experimental study was conducted. The instruments were analysed using differential scanning calorimetry to determine the start and finish temperatures of martensitic (Ms, Mf) and austenitic (As, Af) transformations during controlled heating and cooling cycles. Results. Results: ProTaper Ultimate™ exhibited Af temperatures above body temperature, suggesting the presence of a mixed microstructure under clinical conditions. Plex V™ demonstrated broader transformation ranges and Af values close to body temperature, indicating increased martensitic phase stability. In contrast, Rotate™ showed significantly lower transformation temperatures, with Af values below body temperature and narrower DSC curves, consistent with a predominantly austenitic phase. Conclusion. The evaluated systems exhibited distinct thermal behaviour associated with their metallurgical characteristics. These differences may influence the mechanical performance and clinical behaviour of NiTi instruments during endodontic instrumentation

The use of portable X-ray devices in dentistry, particularly in endodontics, has increased in recent years due to their portability and ease of use. However, their implementation has raised concerns regarding occupational exposure to scattered radiation for operators. Objective: To determine the dose of scattered radiation generated by portable dental X-ray devices under different projection conditions. Methods: A cross-sectional observational descriptive study was conducted evaluating twelve portable dental X-ray units used for radio diagnostic procedures. Scattered radiation measurements were performed at a standardized distance of one meter using tissue-equivalent compensated portable radiation detectors, following the ARCAL XLIX-TP-003 protocol of the International Atomic Energy Agency (IAEA). Variables analysed included scattered radiation level, anatomical measurement zone (head and chest), cone type, and equipment age. Data were analysed using descriptive statistics and non-parametric tests with SPSS software. Results: The median scattered radiation dose was 43.28 µSv/h (IQR: 32.28–49.62 µSv/h), remaining below the reference limit of 250 µSv/h. No statistically significant differences were found in radiation levels according to anatomical zone (p = 0.347) or cone type (p = 0.881). Likewise, no significant correlation was observed between scattered radiation and equipment age (ρ = –0.055; p = 0.799). However, variability among device models was observed, and radiation leakage was detected in the exposure switch of some units. Conclusion: The portable X-ray devices evaluated produced scattered radiation levels within ranges considered safe; nevertheless, variability among models and radiation leakage in certain devices highlight the importance of quality control, adequate shielding design, and strict adherence to radiation protection measures.

Dental pain of pulpal origin during pregnancy is a complex phenomenon that affects both oral health and the physical and emotional well-being of pregnant women. This study aimed to understand the experiences that influence the perception and management of dental pain of pulpal origin in pregnant women from Bucaramanga and its metropolitan area, identifying the emotional, sociocultural, and medical factors that influence their coping. A qualitative research study with a phenomenological approach was conducted with the participation of nine pregnant women selected through logical sampling. Data was collected through semi-structured interviews, recorded, transcribed, and analyzed using Atlas.ti 8® software. From the narrated experiences, emerging categories and subcategories were generated. The results indicate that the perception of dental pain during pregnancy is associated with physiological (hormonal changes), emotional, and cultural factors that influence therapeutic decisions. Barriers were identified related to fear of anesthesia, X-rays, and their potential effects on the fetus, as well as a need for medical approval before accessing dental treatment. Pregnant women resort to self-medication, use of home remedies for pain management, and, in extreme cases, postponing treatment until after delivery. Likewise, a need for coordination between medical and dental services was evident, tailored to the specific needs of each pregnant woman. It is concluded that the perception and management of dental pain during pregnancy are determined by biopsychosocial and cultural factors. The findings highlight the importance of strengthening maternal oral health education, promoting safe and timely dental care, and fostering interdisciplinary support that instills confidence in pregnant women and contributes to improving their overall well-being.

(Universidad Santo Tomás, 2025-12-08) Sandoval Echavarria, Juan David; Martinez Araque, Sergio Andres; Reyes Lopez, Rafael Ricardo; Torres Celeita, Julian; Universidad Santo Tomás
Introduction: endodontic treatment in teeth with calcified canals can make the localization of the root canal system difficult, increasing the risk of perforations, instrument fracture, and treatment failure. Guided endodontics has emerged as a precise alternative that uses cone-beam computed tomography (CBCT) and 3D-printed guides to facilitate access. Objective: to determine the accuracy and the volume of tissue removed during access to a calcified root canal using a CBCT-based endodontic guide, as well as the additional maneuvers required. Materials and Methods: a case report was conducted on a tooth with severe root canal calcification. A digital endodontic guide was designed in Blue Sky Plan® software and printed in biocompatible resin. Preoperative and postoperative CBCT images were compared to determine angular deviation and the volume of dentin removed. Results: access was performed with an angular deviation of 5.06° and a dentin loss of 0.015 ml. Ultrasonics was required as a complementary maneuver to correct the trajectory, achieving successful canal negotiation. Conclusion: partial or Segmented Volume CBCT is not ideal for designing an endodontic guide, as it increases clinical risk in critical areas of calcification. However, an expanded sample size and standardized protocols are recommended to allow meaningful comparisons with conventional methods
Uso de medicación intraconducto en endodoncia. Revisión sistemática.
(Universidad Santo Tomás, 2025-12-06) Castellanos Rodriguez, Maria Camila; Leal Daza, Johann Sebastian; Manosalva Estrada, Maria Alejandra; Universidad Santo Tomás
Introduction. Endodontics is a dental treatment that allows the preservation of non-vital teeth, although it may fail due to the anatomical complexity of root canals or the persistence of resistant microorganisms. Intracanal medication plays a fundamental role in bacterial elimination and postoperative pain relief, complementing the action of irrigating solutions. Among the most commonly used medicaments are calcium hydroxide and triple antibiotic paste, whose clinical effectiveness has been widely evaluated. Objective. To determine the use and effectiveness of calcium hydroxide and triple antibiotic paste as intracanal medicaments in endodontics, according to scientific literature published between 2015 and 2025. Methodology. A systematic review was conducted by searching PubMed, Scopus, Google Scholar, and ScienceDirect databases, using Boolean operators and specific keyword combinations. Studies published between 2015 and 2025, available in full text and written in English, Spanish, or Portuguese, were included. Data were extracted using a standardized matrix that included year of publication, study type, medication used, follow-up time, diagnostic tools, and clinical outcomes. Descriptive and univariate statistical analyses were applied to summarize findings, following quality assessment guidelines. Results. A total of 72 studies were identified. After removing duplicates and applying eligibility criteria, 11 studies were included in the final analysis. Most studies (91.7%) were experimental, while only one was observational. The highest scientific output came from Pakistan, Saudi Arabia, and India. Calcium hydroxide was the most frequently used medicament (58.3%), followed by triple antibiotic paste (25%). The main purposes of intracanal medication were postoperative pain reduction and reduction of periapical lesion size, mainly evaluated using the Visual Analogue Scale (VAS) and combined clinical-radiographic assessment. Short-term follow-ups (<1 month) predominated (58.3%), while long-term follow-ups (>6 months) were scarce. In terms of effectiveness, 25% of studies reported highly effective results, 8.3% partial effectiveness, and 58.4% mixed or unsatisfactory outcomes. Conclusion. Calcium hydroxide remains the reference intracanal medicament due to its availability, biocompatibility, and antimicrobial properties. However, triple antibiotic paste emerges as a promising alternative, especially in resistant or extensive periapical infections.
Conocimiento, actitudes y prácticas de los endodoncistas egresados de la Universidad Santo Tomás extensión Bogotá en la atención de pacientes en condición de discapacidad.
(Universidad Santo Tomás, 2025-12-04) Molano Barrios, Emmanuel; Velasquez López, Maria Camila; Becerra Buitrago, Patricia; Quiceno Olaya, Johanna Angelica; Universidad Santo Tomás
The aim of this study was to evaluate the level of knowledge, attitudes, and practices of endodontists graduated from the Universidad Santo Tomás, Bogotá extension, regarding the care of people with disabilities (PWD), as well as to identify educational gaps and factors associated with their clinical preparedness. The study content addresses the conceptual foundations of disability, clinical implications for endodontic care, the components of the CAPS instrument, and the relevance of inclusive professional training. A quantitative, observational, cross-sectional study was conducted. The population consisted of 650 graduates from the Endodontics postgraduate program at USTA, of whom 330 responded. The CAPS survey, a previously validated instrument for assessing knowledge, attitudes, and practices among health professionals, was applied. Sociodemographic, academic, and clinical variables were collected, along with information on clinical experience, perceived preparedness, communication strategies, and adaptations used during dental care. Results showed that most participants demonstrated basic knowledge, though insufficient for comprehensive management of PWD. Attitudes were generally favorable but accompanied by clinical insecurity and indeterminate perceptions. Regarding practices, participants reported the use of patient-centered communication strategies and involvement of caregivers; however, there were persistent limitations related to adapted infrastructure, inclusive resources, and the application of protocols such as desensitization, sedation, and general anesthesia. Clinical self-perception of preparedness was predominantly low or uncertain. The discussion highlights the consistency between these findings and the existing literature, which describes educational gaps, limited specialized training, and structural barriers that hinder adequate care for PWD. The need to strengthen clinical, communicative, and attitudinal competencies during postgraduate education is emphasized. In conclusion, the current level of preparation among endodontists is insufficient to ensure comprehensive, equitable, and quality care for PWD. These findings underscore the need for curricular adjustments, continuous training, and institutional adaptations to support inclusive and competent dental practice.

(Universidad Santo Tomás, 2025-12-04) Infante Suárez, Liliana Marcela; Navarro López, Carolay Yisseth; Ortiz Castro, Vicky Constanza; Becerra Buitrago, Hernán; Universidad Santo Tomás
The success of endodontic treatment depends on proper cleaning and disinfection of the root canal system. The presence of an apical bubble or “vapor lock” may limit irrigant penetration into the apical third. This study aimed to determine the effect of activation time and ultrasonic device type (corded and cordless) on apical bubble rupture in single-rooted teeth. An in vitro study was conducted using 52 extracted teeth, divided into two groups according to device type, using 5.25% sodium hypochlorite activated in 30-second cycles. The rupture of the apical bubble was radiographically recorded up to 150 seconds. Results showed that 80% of the bubbles ruptured, mainly within the first 30 seconds (28%). No significant differences were found between devices (p=1.00), but a significant relationship with time was observed (p<0.001). It is concluded that activation time influences apical bubble rupture, while the type of ultrasonic device does not.

Anxiety represents a key factor in patients' physiological response during endodontic procedures, as it influences pain perception and treatment duration. Its impact can lead to physiological alterations that compromise patient safety and comfort. The present study aimed to analyze the relationship between anxiety levels and variations in heart rate, blood pressure, and blood oxygen saturation in patients treated in the endodontics postgraduate program at the Universidad Santo Tomás, Bogotá extension, in 2024/2025. The sample consisted of 62 patients who completed the modified Corah dental anxiety test and had their vital signs taken at three points during the procedure: before, during, and after. The data were systematized in Excel, analyzed with statistical tests, and graphically represented using box and whisker plots. The results showed that more than 90% of the patients presented some degree of initial anxiety. Regarding physiological variables, oxygen saturation decreased significantly at the end of the intervention, dropping from 62.9% of patients within the normal range at the beginning to only 30.6% at the end (p < 0.001). In contrast, heart rate showed a progressive normalization, with the number of patients within the normal range increasing from 41.9% to 75.8% (p < 0.001). Blood pressure also improved: 71% had hypertension at the beginning, and this decreased to 33.9% at the end (p = 0.046). These findings suggest that, although anxiety is highly prevalent and impacts physiology, heart rate and blood pressure tend to normalize at the end of the treatment, albeit with a significant decrease in oxygenation, highlighting the need for constant clinical monitoring

Background. Dentoalveolar trauma is a frequent dental emergency among children and adolescents, potentially causing functional, aesthetic, and psychological consequences if not properly managed. In school environments, teachers are often the first responders, which highlights the need to strengthen their knowledge of dental first aid. Objective. To design and validate an educational material on the initial management of dentoalveolar trauma in permanent dentition aimed at school teachers. Methodology. An analytical content validation study was conducted with the participation of eight experts (three endodontists, three pediatric dentists, and two graphic designers) who evaluated the clarity, relevance, and sufficiency of the material. The educational resource was created as a digital brochure using Adobe Illustrator, consisting of 19 illustrated pages that explain dental injury types, emergency procedures, and tooth preservation methods. Content validity was assessed through the Lawshe model, using frequency analysis and the Content Validity Ratio (CVR). Results. The experts demonstrated high acceptance of the material, emphasizing its visual clarity, simple language, and pedagogical suitability. The overall CVR value was 1.0, indicating full consensus among evaluators. Conclusion. The developed educational material is a valid, clear, and useful pedagogical tool to guide teachers in the immediate management of dentoalveolar trauma in permanent teeth. Its implementation may strengthen oral health education, promote prevention, and enhance emergency response in school settings.
Penetración de hipoclorito de sodio en túbulos dentinales: Estudio comparativo de cinco soluciones mediante tinción con cresyl violeta y Estereomicroscopía
(Universidad Santo Tomás, 2025-12-04) Gutiérrez Fernández, Alirio José; Ruiz Pérez, Nelson Junior; Moreno Munera, Marcela; Universidad Santo Tomás
Objective: To establish the level of sodium hypochlorite penetration into dentinal tubules as a function of the product’s pH, viscosity, and concentration, considering three different commercially available brands for household use and two different brands for dental use. Method: Three commercially available brands of NaOCl for household use and two brands for dental use were selected, along with 26 teeth divided into five groups (five teeth per group) and one tooth as a negative control. The teeth were biomechanically prepared, immersed in crystal violet, then irrigated with the respective sodium hypochlorite solutions, subsequently sectioned, and evaluated under a stereomicroscope to observe the degree of penetration. Results: The penetration of sodium hypochlorite into the dentinal tubules was evaluated using five different brands (Group 1 to Group 5). The greatest intratubular penetration was observed in Group 5 (64.0–110.0 μm) and Group 1 (63.1–164.4 μm). Conclusion: The physicochemical properties of the different NaOCl solutions play an important role in their penetration into dentinal tubules. It was observed that some household sodium hypochlorite solutions can perform their function similarly to clinical-use products. However, these must meet all regulatory standards and requirements for clinical application, and further studies are needed to confirm this assertion
Recomendaciones para el manejo endodóntico en pacientes tratados con terapia antirresortiva tipo bifosfonato

Antiresorptive therapy, commonly used in the management of metabolic bone diseases such as osteoporosis and in patients with bone metastases, has been associated with a potential risk of medication-related osteonecrosis of the jaw (MRONJ). The objective of this review was to establish general clinical recommendations for the dental management of patients undergoing antiresorptive therapy, based on the available scientific evidence. A literature review was conducted between 2020 and 2024 using the PubMed, Google Scholar, Science Direct, Web of Science, and Cochrane databases, following methodological guidelines designed to ensure the quality and relevance of the information. Articles published in Q1 and Q2 journals according to the Scimago Journal Rank (SJR) were prioritized, while studies with significant methodological limitations, animal models, or low levels of evidence were excluded. Of the 60 articles initially identified, 24 studies were selected, along with 61 additional papers provided directly by the scientific advisors that met the inclusion criteria. The most common study designs were retrospective studies, followed by case reports and case series. The results show that, although there is extensive literature on antiresorptive therapy, there remains a scarcity of studies specifically addressing endodontic management in this patient population. However, after expanding the search period, it was determined that a structured protocol, including a thorough medical history, interdisciplinary coordination, patient education, and regular radiographic follow-up, is essential to reduce the risk of MRONJ and to facilitate early detection of warning signs.

(Universidad Santo Tomás, 2025-12-03) Carvajal Rodríguez, Daniel Felipe; Villegas González, Isabella; Hernández La Rotta, Johanna Eugenia; Torres Celeita, Julián; Universidad Santo Tomás
The incorporation of the erbium laser in endodontic and surgical procedures offers advantages during bone ablation, as this type of laser not only removes tissue efficiently but also disinfects treated surfaces, reducing overheating and minimizing thermal damage to bone. Objective: To describe the evaluation and management of a patient who underwent periradicular surgery guided by an Er,Cr:YSGG laser, used for incision, osteotomy, and apicoectomy in a case diagnosed with asymptomatic apical periodontitis. Method: A clinical case report was carried out in which the patient’s clinical and radiographic conditions were evaluated before and after the procedure. During the pre-surgical period, the soft tissues were in normal condition, and the apical lesion was evidenced through cone-beam computed tomography (CBCT). Results: At 24 hours post-surgery, moderate inflammation of the soft tissues was observed, with sutures in place and partially adhered wound edges, without signs of bleeding or suppuration. The radiographic evaluation showed a hypodense bone defect corresponding to the surgical area. Bone density readings obtained at 24 hours, 6 months, and 10 months showed a significant decrease during the initial repair phase, with evidence of progressive bone regeneration. Conclusions: The Er,Cr:YSGG laser represents a minimally invasive and effective tool for periradicular procedures, allowing precise manipulation of hard and soft tissues, reducing bacterial load, and promoting optimal conditions for bone healing.

Background. Academic stress and anxiety are highly prevalent psychological problems in the academic environment, especially among postgraduate students in health sciences. Objective. To determine the levels of stress and anxiety in postgraduate dentistry students at the Universidad Santo Tomás, Bucaramanga. Methodology. A descriptive, cross-sectional study was conducted with a sample of 119 students, analyzing sociodemographic variables (sex, age, academic program, and semester) along with the dependent variables of academic stress and general anxiety. The specific dimensions of stress (stressors, physical, psychological, and behavioral reactions) and the components of anxiety (state and trait) were measured using the Academic Stress Inventory (IEA) and the State-Trait Anxiety Inventory (STAI). The research adhered to the ethical principles established in Resolution 008430 of 1993, being classified as a greater than minimal risk investigation. Informed consent was obtained from all participants, ensuring their absolute voluntariness and confidentiality. Results. 89.98% of the participants experience some degree of academic stress, with the academic stressors dimension showing the highest score. Regarding anxiety, 68.7% reported moderate levels, while 67.23% were in a severe level of trait anxiety, suggesting a personal predisposition to anxiety. Although general stress did not show significant differences by program or semester, a statistically significant difference was found in state anxiety (p<0.001) and trait anxiety (p=0.032) in relation to the academic program. The Orthodontics and Oral Rehabilitation programs concentrated the most severe cases, while anxiety and stress levels intensified in the intermediate semesters (third and fifth). Conclusion. The specific demands of each specialty and the stage of training are influential factors in the emotional well-being of the students.

(Universidad Santo Tomás, 2025-11-27) Ardila Jiménez, Camila; Caro Caro, Natalia; Castellanos Hernández, Luna Andrea; Mejía Niño, Hellen Gissel; Manosalva Estrada, María Alejandra; Universidad Santo Tomás
The study analyzes the perception of natural irrigants in endodontics among students and graduates of the Endodontics specialization program at Universidad Santo Tomás, Floridablanca campus. Introduction: Endodontic treatment aims to eliminate microorganisms from the root canal system, and irrigation plays a key role by complementing the mechanical action of the instruments. Traditionally, chemical solutions are used, but there is growing interest in natural alternatives with lower toxicity and proven effectiveness. Objectives: To determine the perception of students and graduates of the Endodontics specialization program at Universidad Santo Tomás, Bucaramanga campus, regarding the use of natural irrigants in clinical practice. Materials and Methods: A quantitative, cross-sectional, and descriptive study was conducted using structured surveys administered to students and graduates of the Endodontics specialization program. A validated questionnaire with multiple-choice questions was used to inquire about clinical experience and perceptions of irrigants. The sample consisted of participants selected intentionally. Results: The findings show knowledge and a neutral perception regarding efficacy and application, although there is willingness to receive training on the subject. Some participants acknowledge advantages such as biocompatibility and low cost, but concerns remain about the scientific evidence and standardization of protocols. Conclusion: It is established that students and graduates of the specialization program have insufficient information about natural irrigants in endodontics, highlighting the need to strengthen academic programs with updated content and scientific support to endorse their use. The study emphasizes the importance of promoting research and pedagogical strategies that encourage knowledge and clinical application of natural options, contributing to a safe, comprehensive, and sustainable approach to endodontic therapy.
Responsabilidad civil del profesional ante el evento adverso previsto en el consentimiento informado en endodoncia. El caso de la IPS de la USTA-FOC Bogotá
(Universidad Santo Tomás, 2025-08-29) Arboleda Carmona, Daniel Esteban; Garzón Mantilla, José Roberto; Hoyos Cardona, Diego Alejandro; Becerra Buitrago, Patricia
This study describes the legal and bioethical aspects related to the civil liability of the endodontist when adverse events occur that are not explicitly addressed in the institutional informed consent. Objective. To analyze the civil liability of the endodontist in relation to adverse events included in the informed consent used by the IPS of the Colombian Dental Federation and to validate a more robust model. Method. A descriptive methodology with a qualitative analytical component was employed, including documentary analysis of the current informed consent, classification of adverse events from clinical cases, and validation of a new format using the Delphi method with three legal experts. Results. Adverse events such as root canal obstruction due to pulp calcification and accidental swallowing of instruments were identified, whose omission in the original consent could imply malpractice and civil liability. The Delphi analysis showed unanimous consensus on criteria of clarity, sufficiency, and legal feasibility, incorporating adjustments such as: strengthening the regulatory framework, inclusion of specific risks, accessible language, graphic resources, and the addition of Dissent and Withdrawal clauses, ensuring the revocability of consent. Conclusions. The current informed consent requires substantial adjustments to become a preventive tool that strengthens patient autonomy and minimizes legal risks. Expert validation confirmed that the proposed model is legally solid and clinically relevant, representing an advance toward an endodontics-specific consent that integrates clinical warnings, legal support, and clear communication, enhancing protection for both patient and practitioner.

(Universidad Santo Tomás, 2025-06-24) Balaguera Velandia, Ludy Mirana; Moreno Segura, Nicolás; Jiménez Peña, Oscar Mauricio
This research was based on quantitative and qualitative paradigms, framed within a positivist perspective, with a descriptive approach focused on the concept of quality of life in graduate students. To this end, the WHOQOL-BREF instrument was used to determine the perceptions of students in the Endodontics program at the Universidad Santo Tomás – Bogotá campus regarding their quality of life, as well as to identify the perceived determining factors that could influence it. A mixed-method study with an explanatory sequential design was conducted. In the first phase, a cross-sectional survey was administered to a sample of 42 students (61% women), followed by six semi-structured interviews (SEs) to complement and interpret the quantitative results. In the initial phase, descriptive statistics were calculated to characterize the collected data. The findings led to the conclusion that the quality of life of resident students in the Endodontics program at the Universidad Santo Tomás – Bogotá Extension is influenced by multiple personal, social, academic, economic, and emotional factors.
Caracterización metalúrgica y resistencia a la torsión de las fresas ULTRADRILL DENTOOLS® Y STECO®
(Universidad Santo Tomás, 2025-06-18) Vásquez Correa, Geraldine; Chávez Andrade, Diana Yulay; Alarcón Pinilla, Anyela Lizeth ; Bastidas Neira, Harrizon Alexander
Endodontic treatment in teeth with obliterated root canals represents a high degree of clinical complexity, with specialized burs being a fundamental resource for guided access. However, the literature on their metallurgical composition and mechanical performance is limited. Objective: To evaluate and compare the metallurgical, physicochemical characteristics and torsional strength of two stainless steel burs used in guided endodontics—Ultradrill Dentools® and Steco®—in order to determine their potential clinical implications in the treatment of sclerotic root canals. Method: Four burs (two from each brand) were analyzed using a standardized disinfection and sterilization protocol. Scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), carbon and sulfur chromatographic analysis, mechanical torsion testing with a calibrated torque wrench, and post-torsion fractographic analysis were performed. Additionally, the morphology of the shank and active edge was evaluated using SEM and stereomicroscopy. Results: Dentools® burs showed greater torsional strength, with values between 1.2 and 6.8 times higher than those recorded by Steco® burs. Compositional analysis revealed that Dentools® contains nickel and titanium, and lower sulfur and carbon contents, corresponding to an austenitic steel; while Steco® presents a maraging steel with greater hardness but lower toughness. All samples exhibited ductile fractures. At the macroscopic level, both burs showed an italic "S" active shape, with dimensional variations compared to the values reported by the manufacturers. Dentools® presented greater surface homogeneity and fewer crack lines in the shank. Conclusions: There are significant differences between the two systems evaluated, both in their chemical composition and mechanical behavior. Ultradrill Dentools® burs, made of austenitic steel, offer greater torsional strength and ductility, desirable characteristics in highly demanding clinical procedures. The lower sulfur-to-carbon ratio suggests greater corrosion resistance. Further studies evaluating the wear and clinical durability of these instruments are recommended.
Técnica Biomimética como tratamiento alternativo para la conservación del diente tratado endodónticamente y estructuralmente comprometido. Caso clínico.
(Universidad Santo Tomás, 2025-06-18) Zambrano Diaz, Paola Magdalena; Sierra Gulloso, Eliane Yulieth; Bonilla Ramirez, Ana Maribel; Gutiérrez Alvares, Biviana Carolina
Problem: the restoration of endodontically treated teeth presents a significant challenge due to intrinsic structural deficiencies, tissue loss, and the presence of previous restorations. Method: the introduction of adhesive materials and procedures has transformed how endodontically treated and structurally compromised teeth are restored. Polyethylene fibers, with an elastic modulus similar to dentin, can be used as a material for core buildups. For this reason, they have been replacing the use of intraradicular retainers and have gained popularity. The use of these materials preserves more tooth structure, distributes forces uniformly along the tooth's longitudinal axis, and adapts to the root canal walls, improving resistance. This conservative approach not only avoids the need for prosthetic materials like intraradicular retainers to support a crown, which, while effective, may not offer optimal integration with the natural tooth tissues, but also allows for a restoration that not only reinforces the tooth but is also functional and aesthetic. Objective: This study aims to present a clinical case with a biomimetic approach as an alternative treatment for the conservation of endodontically treated teeth that present significant structural compromise, with a six-month follow-up. Results: The clinical case to date demonstrates that the biomimetic technique has been effective in rehabilitating structurally compromised teeth. The absence of periapical lesions, the reduction in periodontal ligament widening, the recovery of soft tissues, and, above all, keeping what was previously considered lost still in the mouth, are indicators of treatment success. Conclusions: Materials and the application of biomimetic techniques are allowing for less invasive restoration of teeth for direct reconstruction of teeth with significant structural loss of dental tissue. The use of polyethylene fibers in conjunction with resins to reinforce the root and coronal structure appears to be a viable treatment option, demonstrating to be an effective alternative for maintaining tooth functionality.

The sterilization of instruments is a key aspect in ensuring the success of endodontic treatments; however, there are no standardized protocols to reliably guide professionals. Objective: to evaluate the effectiveness of the sterilization process of the VDW Rotate®, Trunatomy® and One curve® instruments. Method: descriptive, observational, cross-sectional study, with a sample of 45 files (15 One Curve®, 15 Rotate®, and 15 Trunatomy® in their basic sequence), which were used to instrument teeth diagnosed with symptomatic/asymptomatic apical periodontitis and chronic/acute periapical abscess. After use, they were subjected to a sterilization process and evaluated by microbiological testing to verify the efficiency of the process.
