Evaluation of Infraorbital Foramen Position Using Cone-Beam Computed Tomography in a Cohort of Central Gujarat, Indian Population.

Abstract

The location of infraorbital foramen varies between geographic locations. Thus, population-specific information is required to facilitate the prediction of its exact location. A cross-sectional study was conducted on 100 cone beam computed tomography (CBCT) sections to evaluate the distance between the infraorbital foramen and incisal edge of the maxillary central incisor, the occlusal plane of the maxillary second premolar, and the alveolar crest over the maxillary second premolar using CBCT in Central Gujarat, Indian population. Descriptive statistical analysis was performed to calculate means and standard deviations for each measured parameter.The statistical significance level was defined at p<0.05. The distance between the infraorbital foramen and incisal surface of the maxillary central incisor was (mean ± standard deviation) R=49.39 ± 3.12 mm and L=49.49 ± 3.29 mm, the occlusal plane of the maxillary second premolar was R=39.02 ± 2.65 mm and L=39.49 ± 2.53 mm, and the alveolar crest over the maxillary second premolar was R=32.64 ± 2.67 mm and L=31.64 ± 2.33 mm. There was no significant difference in the mean values of all variables between genders and age groups (p>0.05). The distance between the infraorbital foramen and the alveolar crest over the maxillary second premolar was greater on the right side (p<0.05). The results of this study were analogous to those observed in a cohort of the Turkish population but varied from those observed in a cohort of the Sri Lankan population. Hence, more population-specific studies are required.
