Prevalence of Maxillary and Mandibular Exostosis in Mississippi Population: A Retrospective Study

Abstract

Abstract Purpose The objective of this study was to determine the prevalence of exostosis in the Mississippi population. Methods Patient archives of the UMMC School of Dentistry between January 2018 and May 2021 were examined. The patients with exostosis were included in the study based on the findings in intraoral photographs, full-moth series (FMS), panoramic radiographs, and cone-beam computerized tomography (CBCT) images of the patients. The patients were excluded from the study if they do not have maxillary or mandibular exostosis. In addition, patients' age, gender, and ethnic origins as Caucasian, African-American, and Asian were recorded. All data of exostosis was evaluated and categorized according to age, gender, and ethnicity. Multiple logistic regression analysis was performed for more detailed statistical analysis. Results A total of 1242 patients were examined for the presence of maxillary and mandibular exostosis. 303 patients were diagnosed to have maxillary and/or mandibular exostosis among the Mississippi population with a prevalence rate of 24.4%. Exostosis was seen more in females (57.4%) compared to males (42.6%). The highest prevalence of exostosis was seen in Caucasians (71.3%), African-Americans (23.8%), and Asians (5%). Conclusion High prevalence of exostosis was seen in the Mississippi population. Our findings will help clinicians to be more aware of these bony protuberances and thus better at diagnosing them. This may specifically help oral surgeons, periodontists, and prosthodontists in pre-prosthodontic surgery and denture fabrication.
