- The purpose of the present study was to assess the presence and course of the incisive canal (IC) in the mental interforaminal region according to dental status, age, and sex using cone-beam computed tomography (CBCT).
The right and left sides were retrospectively studied in 356 patients (n = 712). Axial, sagittal, cross-sectional, and panoramic images were evaluated, and three-dimensional images were reconstructed and evaluated as necessary. The morphology, course, and length of mandibular ICs and the inner and outer diameters of the canals were measured. The reliability and reproducibility of measurements were examined using the intraclass correlation coefficient and the coefficient of variation.
The IC was found on 91 % of images, and its mean length anterior to the mental foramen was approximately 12.4 mm. The mean distance of the IC from the lower mandibular border was 10.5 mm, and its course was closer to the buccal border at the starting point; it deviated lingually through the anterior mandible. Statistically significant differences in the course and localization of the IC were found in edentulous and older patients (p < 0.05).
A high proportion of mandibular canals can be detected by CBCT imaging. Clinicians should be careful during implant or bone surgery procedures to avoid possible complications, with special emphasis on patient age and dental status, using this imaging modality that minimizes radiation exposure.
