“Evaluation of Radiomorphometric Indices and Fractal Dimension of Mandible Using Cone Beam Computed Tomography among Tobacco Habitudes - A Case Control Study”

Abstract

Purpose: The purpose of the study was to assess how smoking and smokeless tobacco affected the mandibular bone structure using a variety of radiomorphometric indices and fractal dimension (FD) analysis.

Material and methods: 189 patients—63 smokers and 63 patients using smokeless tobacco and 63 healty controls, were included in this study. In the trabecular bone of the mandible, eight areas of interest of 30x30 pixels were chosen, and fractal dimension analysis was carried out. All digital panoramic radiographs were used to measure the mandibular index and mandibular cortical thickness. All values were compared between groups. Utilizing the Kruskall Wallis ANOVA followed by pair wise comparison using Mann Whitney U test data were evaluated.

Results: A total of 189 patients between the ages of 20 and 55 were evaluated. Fractal dimension values showed statistically significant difference between the groups. Similarly, statistically significant differences between groups were seen for MCI and MCT measures (p>0.05).
