A retrospective comparison of the location and diameter of the inferior alveolar canal at the mental foramen and length of the anterior loop between American and Taiwanese cohorts using CBCT.

Purpose: The aim was to retrospectively compare the measurements of the location and size of the inferior alveolar canal at the mental foramen and the length of the anterior loop between two cohorts of Americans and Taiwanese using cone-beam computed tomography (CBCT).

Methods: CBCT was performed with an I-CAT(®) Cone-Beam 3D Dental Imaging System and reconstructed into multiple-plane views to measure two populations.

Results: There was no statistically significant difference (P = 0.
