Objectives: To compare the quality of life (QOL), side effects, risks, and complications following mandibular third molar coronectomy compared with conventional third molar extraction.
Methods: Sixty-nine patients referred for extraction of impacted mandibular third molars were prospectively studied. The decision to perform coronectomy was made according to radiological data indicative of a risk for inferior alveolar nerve injury. The patients were asked to fill out a questionnaire on their QOL during the first postoperative week, and the surgeon was asked to fill out a questionnaire on these patients' demographic, clinical, and radiological details as well as surgery-related data. The study participants were followed up for at least 1 year postoperatively.
Results: Thirty-four of the 69 patients underwent coronectomy (study group) and 35 underwent full extraction (control group(. There was no group difference in QOL scores during the first postoperative week. There was no patient of nerve injury in either group. No complications were found in the postoperative period. Two patients of coronectomy necessitate residual tooth removal prior to planned orthodontic treatment.
Conclusions: These patients' QOL are similar to those for patients following total extraction. No difference in side effects following procedure was found between coronectomy and total extraction.
Clinical Relevance: Coronectomy of impacted mandibular third molars may be offered instead of total extraction in patients presenting radiological characteristics of root proximity to the inferior alveolar nerve.

Objective: Imbalanced autonomic nervous system (ANS) activity raises concerns about the development of systemic complications during dental treatment. The purpose of this study was to determine whether a psychological test (Toho Medical Index (TMI)) prior to the impacted mandibular third molar extraction can identify patients with potentially imbalanced autonomic function.
Materials And Methods: In this prospective study, 34 healthy adult patients with no history of systemic disease were assigned to either the autonomic imbalance group (type II, III, IV) or the control group (type I) based on the results of the TMI.

Background: The presence of mandibular third molars has been associated with the risk of mandibular fractures, highlighting the need for comprehensive studies considering the interaction with other mandibular structures. This study investigates how mandibular third molars and neighboring tissues can influence the structural fragility of the mandible using finite element analysis.
Material And Methods: A finite element analysis study following the guidelines proposed by RIFEM 1.

Background: Establishing accurate, reliable, and convenient methods for enamel segmentation and analysis is crucial for effectively planning endodontic, orthodontic, and restorative treatments, as well as exploring the evolutionary patterns of mammals. However, no mature, non-destructive method currently exists in clinical dentistry to quickly, accurately, and comprehensively assess the integrity and thickness of enamel chair-side. This study aims to develop a deep learning work, 2.

Objective: To investigate the clinical application effect of the along-axis extraction method in the extraction of impacted mandibular third molars (IMTM) and to compare the biomechanical characteristics of different root extraction techniques through three-dimensional finite element analysis.
Methods: A total of 68 patients requiring IMTM extraction were enrolled and randomly divided into two groups: the experimental group underwent the along-axis extraction method, while the control group underwent the traditional buccal bone removal and root extraction method. The duration of the procedure, intraoperative and postoperative complications were recorded.

Protraction of a mandibular second molar to substitute the adjacent missing first molar is challenging in clinical practice. In this case report, we demonstrated a 21-year-old patient with an untreatable periapical lesion of the mandibular right first molar. The adjacent mandibular second molar had normal root length and the third molar was mesially-impacted.
