Evaluation of mental foramen localization in children by age and gender using cone-beam computed tomography

Abstract

Aim: This retrospective study was carried out to obtain detailed data on mental foramen localization differences, which can guide dental practices such as endodontic treatments, surgical procedures, and dental anesthesia, preventing complications. Cone-beam computed tomography (CBCT) images of individuals aged 7–18 were analyzed according to gender and age.

Methodology: The CBCT images of 120 individuals who met the research criteria were divided into six groups according to age, and 240 hemimandibles were measured. The gender distribution of the patients in each group was equal. Measurements were obtained using 3D volumetric images obtained via CBCT and the RadiAnt DICOM Viewer. When examining the differences between the groups, the Mann–Whitney U test was used for paired groups, and the Kruskal–Wallis H test and post hoc multiple comparison tests were used for groups of more than two.

​Results: Statistically significant differences in the parameters related to mental foramen localization were determined between the gender and age groups (p<0.05). No statistically significant differences were found between the right and left sides of the individuals in all measurements (p>0.05). Further, the mean values ​​of the anatomical points were determined, which can be used to guide pediatric and general dentistry practices.

Conclusion: In the present study, the mean values ​​of the anatomical points measured were determined. Our study suggests that these values ​​can be used as a guide in pediatric and general dentistry applications, such as local anesthesia, endodontic treatments, and surgical operations.
