Abstract
Purpose: This laboratory study aimed to evaluate age-related differences in root canal curvature of human mandibular first molars using high-resolution micro-computed tomography (micro-CT). Methods: Mesial roots of extracted human mandibular first molars (n=93) were collected and classified into three age groups: ≤30 Years, 31−59 years, and ≥60 years. The root canal curvature was evaluated in both the mesiodistal and buccolingual planes using micro-CT reconstructions analyzed in AutoCAD according to Pruett’s method. Results: Curvature values were consistently greater in the buccolingual than in the mesiodistal plane across all age groups. Mesiobuccal and mesiolingual canals exhibited similar patterns, and no significant differences were observed among the age groups (p>0.05). Conclusion: Mandibular first molars exhibited consistent canal curvature across age groups. Although age did not significantly affect this parameter, careful preparation and appropriate instrument selection remain essential for mesial canals in all patients.
