Prevalence of torus palatinus in a population of young and adult Israelis.
The prevalence of torus palatinus, a common exostosis with a debatable pathogenesis, was epidemiologically investigated in a group of 1002 Israeli Jews. This protuberance was observed in 21% of the entire sample, with non-significant differences among different age groups. The smooth type of torus was noted in 72.9%, 68.1% were smaller than 2 cm, and 53.8% were located in the molar area only. The prevalence of torus palatinus in the combined molar-premolar area increased with age, whereas in the molar area it decreased, expressing a significant relation between location and age (p < 0.01). The prevalence of tori larger than 2 cm was much higher in the 21-year and older age groups than in the younger groups. The diverse prevalence of torus palatinus in some of the ethnic groups was also statistically significant (p < 0.05). The aetiology of this common osseous outgrowth is probably multifactorial, including environmental factors acting in a complicated and unclear interplay with genetic factors.
