Introduction: Impacted mandibular third molars pose challenges in dental practice, often requiring surgical intervention. This retrospective study aims to analyze the demographics, impaction patterns, and anatomical relationships of impacted mandibular third molars among Saudi patients.
Methodology: Data from 722 patients visiting the Department of Maxillofacial Surgery and Diagnostic Sciences at Jizan University were retrospectively analyzed. Parameters including gender distribution, impaction types, relationship with the mandibular canal, and age demographics were evaluated based on panoramic radiographs.
Results: Bilateral impaction predominated (57.59%), with mesioangular impaction being the most common (46.51%). Gender differences were noted in impaction types and relationships with the mandibular canal. Interruption of white lines of the canal was more frequent in males (70.00%). Early adulthood (20-25 years) exhibited the highest prevalence of impaction.
Conclusion: The study provides insights into the demographics and characteristics of impacted mandibular third molars among Saudi patients. Gender-specific variations and age distribution underscore the importance of tailored treatment approaches and early intervention.

This study aimed to investigate the age-related alterations in mesial roots of mandibular first molar in terms of root canal curvature values, dentin thickness, interorifice distance, deviation from apical foramen, and location of apical foramen using a three-dimensional curvature measurement method and micro-computed tomography (micro-CT). Forty-five mesial roots of mandibular first molars from three age groups (Group 1: ≤ 30 years, Group 2: 31-59 years, Group 3: ≥ 60 years) were scanned using micro-CT. The central axis of each mesiobuccal and mesiolingual canal was analyzed using cubic B-spline curves to calculate canal curvature.

Functional reconstruction of large mandibular defects, especially in young patients, presents a significant clinical challenge. The ideal approach should not only restore skeletal contour but also address nerve deficits and facilitate final occlusal rehabilitation, all while minimizing morbidity. This report describes a comprehensive, multi-staged strategy for such a case.

Introduction: The mandibular canal has been considered a stable anatomic reference structure and continues to be recognised as a primary vertical structure in 2D mandibular superimposition. However, whether the mandibular canal is stable in the transverse dimension is unclear.
Material And Methods: This retrospective longitudinal study utilised cone beam computed tomography (CBCT) images of 17 subjects (9.

Endodontic-periodontal lesions (EPLs) complicated by cemental tears present a diagnostic and therapeutic challenge. This case report describes the successful management of a 66-year-old male patient with a mandibular second molar (#18) exhibiting an EPL complicated by a cemental tear. Clinical examination revealed a draining sinus tract, deep periodontal pockets, and radiographic evidence of a "J-shaped" lesion and a radiopaque cemental fragment.

Introduction And Aims: Calcified root canals in mandibular anterior teeth present significant therapeutic challenges due to their narrow anatomy and minimal tolerance for procedural errors. This case report demonstrates the successful integration of robot-assisted navigation with an ultra-fine bur to address these challenges.
Methods: A 44-year-old male presented with symptomatic chronic apical periodontitis and pulp calcification in a mandibular lateral incisor, 20 years after orthodontic treatment.
