Gender Related Changes of Bizygomatic Diameter, Maxilla and Foramen Magnum in Different Age Groups Background: The purpose of this study was to assess the relationship between gender and the measurements/evaluations acquiered from skull base on cone beam computed tomography images in people at different decades.Methods: The study was performed on 100 CBCT images of the subjects in five different decades (age-ranged between 20-29, 30-39, 40-49, 50-59 and 60-69). A classification in eight categories was used for the categorisation of foramen magnum type. The dimensions of foramen magnum and maxillary alveolar region measured transversally and sagitally. Byzigomatic width measured transversally. The evaluations were repeated twicely. Data was analyzed in IBM SPSS Statistics 21.0. For statistically significance, p<0.05 was accepted as criteria.Results: In males "hegzagonal" type, in females "egg shaped" type was the most common forms. However, gender has no effect on the distribution of foramen types (p=0.841). Statistically significant difference was found between gender and all other measurements (p<0.05 for each one).
Conclusion:The importance of radiologic data in forensic sciences is increasing. It was observed that data obtained from CBCT was compatible with data achieved from anatomic and CT studies using for determination of gender. It is foreseen that oral and maxillofacial radiology has an important contribution not only in the diagnosis of diseases, treatment and following of prognosis but also in forensic sciences.
