Objective: The purpose of the study is to explore the capability of the CBCT to provide information concerning the position and dimensions of the mandibular incisive canal in relation to adjacent anatomical landmarks. Methodology: CBCT scans of 150 subjects were retrospectively studied to analyze the dimensions of the mandibular incisive canal and to assess the relationship of the mandibular incisive canal to the adjacent anatomical structures of the mandible. Results: 150 CBCT scans were evaluated for the position and dimensions of mandibular incisive canal to adjacent structures. In 87% of cases, the MIC was identified and had a mean length of 13.4mm (range, 5.6 to 24.7 mm) on the right side and 12.4 mm (range, 4 to 22.5 mm) on the left side. From the mental foramen, the incisive canal runs forward toward the incisors, in a slight downward direction, with its diameter decreasing as it progresses towards the midline. Discussion: The data from this study indicates surgical anatomic relationships should be considered in pre-surgical planning to avoid neurosensory disturbances and other potential complications. With the increased interest in performing a thorough pre-surgical examination in the inter-foraminal region, crosssectional images should be utilized to obtain information on the appearance, location, and course of the foramina and canals and their relation to other anatomical structures of the jaw.
