This research aimed to determine the prevalence of exostosis among individuals in Mississippi. A review of the patient database at the UMMC School of Dentistry was conducted from January 2018 to May 2021. Subjects presenting with exostosis were identified and enrolled through evaluation of intraoral photographs, full-mouth series (FMS), panoramic radiographs, and cone-beam computerized tomography (CBCT) scans. Individuals lacking either maxillary or mandibular exostosis were not considered for inclusion. Additionally, demographic information—namely age, sex, and racial background categorized as Caucasian, African-American, or Asian—was collected for each subject. All exostosis-related data were subsequently analyzed and organized by age, sex, and racial background. To obtain a more granular statistical picture, multiple logistic regression analysis was applied. The presence of maxillary and mandibular tori was investigated in a sample of 1242 patients. Of these, 303 individuals in the Mississippi cohort received a diagnosis of maxillary and/or mandibular tori, yielding an overall prevalence of 24.4%. The condition was more commonly encountered among females (57.4%) than among males (42.6%). When stratified by race, the highest frequency was documented in Caucasians (71.3%), with African-Americans accounting for 23.8% and Asians comprising 5%. A notably high prevalence of exostosis was observed in the Mississippi population. The data generated from this work can heighten clinical awareness of these bony protrusions, thereby strengthening diagnostic accuracy. This knowledge may prove especially valuable for oral surgeons, periodontists, and prosthodontists engaged in pre-prosthetic surgical planning and denture construction.
