Morphometric study of incisive canal and its anatomic variations in brazilian individuals.

Objective: To conduct a morphometric evaluation of the incisive canal, adjacent structures, and their anatomic variations in Brazilian individuals. Methods: A retrospective study was conducted using a sample of 157 multislice computed tomography images of adult Brazilian individuals of both sexes (20-96 years). The exam was performed with the RadiAnt DICOM Viewer 4.0.1 (64-bit) software that uses the DICOM PACS standard for visualization of medical and dental images. Results: The values for length and height of the canal, thickness of the palatine bone plate, and latero-lateral diameter of the incisive foramen were higher in men than in women (p < 0.05). Conclusion: The findings of this study demonstrated morphometric differences for the following parameters: latero-lateral diameter; width of canals at all levels measured; palatine bone plate height; canal length and palatine bone plate thickness in relation to the male and female sexes in the Brazilian population.
