An analysis of the first and second mandibular molar roots proximity to the inferior alveolar canal and cortical plates using cone beam computed tomography among the Saudi population

Cone beam computed tomography cross-section of a mandibular molar root. The buccal (R1) and lingual (R2) cortical plate measurements are shown. The total bone thickness including the root (R3) and the distance to the IAC (R4) are also included. R1 - distance from the outer boundary of the buccal cortical plate to the buccal root surface, R2 - distance from the outer boundary of the lingual cortical plate to the lingual root surface, R3 - total bone thickness including the root, R4 - shortest distance from the outer surface of the cortical boundary of the inferior alveolar canal to the nearest root surface.
