Tori are nonneoplastic self-limiting, bony exostosis that are commonly called torus palatinus (TP) when seen on the hard palate and termed torus mandibularis (TM) when seen on the lingual surface of the mandible. These lesions have long been known to anthropologists and have mostly been identified incidentally during routine dental examinations. The prevalence of tori varies in different populations from 0.0% to 66% for TP and between 0.1% and 63.4% for TM. The exact etiology is still unclear, but the most accepted theory today is 30% attributed to genetics and 70% to environmental factors. Hence, the aim of this study was to determine the prevalence of tori and study their morphology among various ethnic groups of a Malaysian population.
