The American Association of Endodontists, or AAE, is a not-for-profit organization of endodontists and other professionals with an interest in endodontics founded in 1943.The current Board of Directors is published on the Association's website. Headquartered in the Two Prudential Plaza Building in Chicago, Ill., the Association represents more than 7,400 members worldwide. Endodontics is one of 12 dental specialties formally recognized by the American Dental Association..
In the dynamic realm of restorative dentistry, a paradigm shift is underway, redefining the very essence of how we approach tooth restoration. No longer confined to traditional mechanical methods, the field is now embracing biomimetic dentistry—an innovative philosophy that prioritizes the preservation of natural tooth structure and the intrinsic vitality of dental pulp. At the forefront of this movement is Biobase, a leader in developing materials that closely emulate the properties of dentin while incorporating advanced adhesive techniques that minimize stress from resin polymerization. By harnessing these cutting-edge materials and strategies, this approach not only restores the functionality of teeth but also mirrors the natural biomechanics of healthy dentition. This article delves into two compelling clinical cases exemplifying the power and promise of biomimetic restorative protocols, showcasing a future where dental care is as much about conservation as it is about restoration.
Background: Saliva is recognized as a promising diagnostic fluid due to its non-invasive nature and ability to reflect systemic and oral health. Among salivary biomarkers, lactate dehydrogenase (LDH) holds diagnostic value as a cytoplasmic enzyme released during cellular injury or necrosis. Establishing normative salivary LDH levels is critical for distinguishing physiological from pathological states. Objective: To estimate the concentration of salivary LDH in healthy adults to establish reference values. Methods: This cross-sectional observational study was conducted over six months (May to November 2017) at the Dept. of Oral and Maxillofacial Surgery, Dhaka Dental College. Thirty healthy adults (30–65 years) were enrolled via convenience sampling. Unstimulated whole saliva was collected in the morning and LDH levels were assessed using validated enzymatic biochemical assay. Data were analyzed using SPSS v22.0, and Student’s t-test assessed gender differences. Results: The mean salivary LDH level was 408.7 U/L (SD: 401.6 U/L). No significant difference was observed between male and female participants (p > 0.05). Conclusion: This study provides preliminary reference values for salivary LDH in healthy adults, which may support future diagnostic applications. Further research on larger, demographically diverse populations is warranted. Journal of Dentistry and Allied Science, Vol. 8 No 2: 48-53
Introduction: Endodontic therapy is one of the most common and significant treatments in daily dental practice. The modern development of technologies, materials, and techniques often creates the impression that success depends mainly on equipment, which can lead to neglecting the fundamental biological and clinical principles. Objective: This lecture aims to reaffirm the fundamental principles of high-quality and predictable endodontic therapy, from proper diagnosis to the final post-endodontic restoration. Content: Key stages of endodontic treatment will be addressed: diagnosis, treatment planning, access cavity design, recognition of root and coronal anatomy, mechanical and chemical preparation of the canal system, criteria for adequate obturation, and the influence of restoration on long-term success. Clinical cases will also be presented, analyzing reasons for failure and possibilities for retreatment. Conclusion: Predictable results are achieved not solely through modern technology, but through proper diagnosis, adherence to biological principles, and a systematic approach to each clinical case.
Aim: To evaluate the debris extrusion during retreatment using continuous rotation motion of canal obturated with gutta-percha and bioceramic sealer using three different obturation techniques. Materials and methods: A total of forty-two extracted mandibular premolar single canals were used in this study. All teeth were divided into three groups according to obturation techniques (n=14 each); Group (A) using single cone technique (SCT), Group (B) using warm vertical compaction technique (WVC), and Group (C) using lateral condensation technique (CLC). During Retreatment, gutta-percha was removed using ProTaper Universal system retreatment files in continuous rotation motion. Debris extrusion during root canal filling removal was assessed using the microbalance. Results: The highest mean weight of apical Debris extrusion was recorded with WVC technique followed by CLC while the least debris extrusion was recorded in SCT obturation technique. There was a statistically significant difference between group WVC and the other two groups, while there was no significant difference between group SCT and group CLC Conclusion: Retreatment of canal obturated using single cone obturation technique and Bioceramics sealer extruded minimal amount of debris.
Background: The mineral trioxide aggregate (MTA) based bio-ceramic (MTA-BCS) has become quite well known for its top-notch amenities.The quality of the obturation procedure is influenced by the composition and handling characteristics of the root canal sealers.Flow, film thickness and setting time are the most important handling properties as they affected the ability of the sealers to enter narrow and irregular spaces.Objective: The aim of the current study was to evaluate 3 commercially available MTA-BCS sealers regarding flow, film thickness and setting time.Materials and methods: Three commercially available MTA based sealers were used in this study.Samples were divided into three groups; Group I (MTA fillapex), Group II (Ceramoseal HBC) and Group III (Endoseal MTA).Flow, film thickness, initial and final setting time were tested according to ISO 6876 standards.Results: For the flow, test Group I showed the highest mean value (26.50±0.50mm) and the lowest statistically significant mean value was Group II (22.59±1.94mm).For the film thickness, the highest statistically significant mean value was recorded in Group II (29.4±4.72 μm) while the lowest mean value was recorded in Group III (15±3.53μm).For initial setting time, the highest statistically significant mean value was recorded in Group I (858.51±11.82min).The lowest statistically significant mean value was recorded in Group III (35.2±2.86 min).For final setting time, group I was unable to set up to one month.Group III was the shortest statistically significant mean value (150.4±3.44 min) compared to Group II (832±6.78min). Conclusion:Within the limitation of this study, it can be concluded that all the tested sealers fulfilled the requirements of ISO specifications no 6876 for flow and film thickness.Regarding setting time, only Group II fulfilled their manufacturer declaration for initial setting as stated by ISO.
