Anterior mental loop, inferior alveolar nerve, mental foramen, mandibular incisive canal.

Background: The aim of the study was to evaluate the vital anatomical structures in the mandibular inter

foramin region and to investigate the presence of sexual dimorphism with respect to the left and right sides

region using CBCT.

Materials & Method: A total of 60 CBCT scans (30 male & 30 female) were analysed for the MF position

& shape, presence and measurement of AL & MIC (both in mm), patterns of emergence of mandibular

canal, symmetry of MF & AL. All the scans were taken by CS 9300 (Care stream Health India Private

Limited) CBCT machine adjusted at 80 kVp, 15mA, Voxel size 0.3x0.3x0.3 and field of view (FOV) of

10x5 (mandible only). The acquired images were reconstructed into multiplane views (axial, panoramic and

cross-sectional) for evaluation.

Results: Position 4 of MF (below the apex of second premolar) was most common on right side while

position 3 (between first & second premolar) on left side, with 75% of symmetrical MF position. The

prevalence of MIC was noted in 93.75% of the patients with mean length of 12.09±5.95 mm. The prevalence

of AL was 53.13% with mean length of 1.07±1.42mm.

Conclusion: The present study recommends a CBCT evaluation of inter-foraminal anatomical structures

before planning the placement of implants. However, no sexual dimorphism was found regarding these

parameters.
