Incidence of retromolar canal in mandible using CBCT: An institution based retrospective study

TL;DR

This study determines the occurrence of retromolar canals in the mandible using CBCT scans, finding a 63.3% incidence rate.

Contribution

The study provides a new institution-based incidence rate of retromolar canals using CBCT imaging.

Findings

RMC was present in 64 out of 101 CBCT scans.

The incidence rate of RMC was found to be 63.3%.

Abstract

Retromolar canal (RMC) is an anatomic structure located in the Retro molar area distal to the third mandibular molar. The retro molar
area is considered as an imperative site where many dental surgeries are being held and due to increasing demand for surgical procedure
in the retromolar area of the mandible. The identification of the retromolar canal has become an issue of clinical concern. Therefore,
it is of interest to determine the incidence of RMC in the mandible using CBCT and measure the distance between the Retro molar Foramen.
Hence, 101 CBCT scans were examined to detect the presence of RMC on 3D CBCT. Data shows that the RMC was present in 64 out of 101 scans
with 63.3% incidence rate.
