Abstract

 ' Bony exostoses are non-pathological, asymptomatic bony outgrowths in various parts of the upper and lower jaw within the oral cavity. They are differentiated mainly into two groups: torus mandibularis when found on the mandible and torus palatinus when found on the palate; however significant as they can interfere with the retention of dental prostheses, lead to obstructive sleep apnea, limit tongue movements or be used as a source of autogenous bone graft in Implant Dentistry.

 ' This is a descriptive, cross-sectional epidemiological study carried out among 938 subjects in a multi-ethnic setting, within 12 - 90years of age, 37.58 ± 13.3 (Mean ± SD), aimed to determine the prevalence of these bony outgrowth. Ethical clearance was obtained from the medical ethics and research committee of the federal capital territory, data collection tool was a pre-tested self-administered questionnaires and analysis was done with Statistical package for social science (SPSS) version 22. Frequency distribution tables were obtained, and chi-square test and students’ t-test were used to compare differences between the various groups present. Statistical significance was set at p < 0.05.

 ' A prevalence rate of 15.9% for torus palatinus and 19.3% for torus mandibularis was recorded in this study with torus palatinus being more present in females 20.5% than male 9.6% and this was statistically significant. Also, of statistically significant was torus palatinus for age-group 20 - 29 years of age and torus mandibularis in equally proportion for age- group 30-39years of age at 22.8% and 40 - 49years of age at 22.8%. There were no statistically significant relations recorded for torus palatinus or torus mandibularis with the ethnic origin of subjects present in this study.

 ' There are reported studies in Nigeria where statistically significant relationship was established between ethnicity and bony exostosis; however, no such relationship was reported in our multi-ethnic study.
