Abstract

Background and objectives: Mandibular incisors mostly have 1 root canal. The purpose of this study was to investigate the prevalence of root canals configurations in mandibular incisors and to investigate the gender prevalence.

Methods: A total of 1200 patients’ cone-beam computed tomography scans were screened and evaluated by two independent maxillofacial radiologists assessed the axial, sagittal, and coronal sections. Inclusion criteria applied to 429 patients; 200 females and 229 males, aged 14 to 75 years with total of 1716 mandibular incisors were evaluated. Inclusion criteria: Available Cone-beam computed tomography BCT images of mandibular anterior teeth with complete root formation, the presence of at least 1 central or lateral mandibular incisor in the scan, absence of root canal treatment, absence of coronal or post coronal restorations, absence of root resorption or periapical lesions and high-quality im- ages. Canal configuration was classified according to the following criteria of Vertucci: type I, II, III, VI, V, VIII, VI, VII and VIII. The root canal morphology was recorded and analyzed.

Results: The prevalence of type I root canal in mandibular incisors was found in 1360 teeth (79.254%), type III was found in 348 teeth (20.279%) and type II was found in 8 teeth (0.466%) while types VI, V, VIII, VI, VII and VIII were not detected.

Conclusions: The occurrence of more than 1 root canal mandibular incisors is approximately 20% while single canal in mandibular incisors was (79 %), the difference in the canal types configurations and genders between the central and lateral incisors are non-significant.
