Abstract

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 = 0.2681) in the distance from the mental foramen to the inferior border of the mandible (mandibular border height) between Americans (9.84 ± 2.01 mm) and Taiwanese (10.13 ± 1.66 mm). No significant difference was found (p = 0.1161) in the inferior alveolar canal diameter between these two cohorts (2.26 ± 0.67 and 2.13 ± 0.47 mm, respectively). However, the anterior loop length of Taiwanese (7.61 ± 1.81 mm) was significantly longer than that of Americans (6.22 ± 1.68 mm) (P < 0.0001).

Conclusion

Our study indicated that (1) the location of mental foramen of Americans was closer to the inferior border of the mandible than Taiwanese; (2) the diameter of the inferior alveolar canal of Americans was larger than Taiwanese; (3) the anterior loop of Taiwanese was longer than Americans. These differences may be, at least partly, due to the racial influence and this information may possess potential valuable clinical relevance.
