“…23 Small tori were found more frequently than large tori, as in previous reports. 4,[11][12][13] This finding contrasted with a study in Malaysia. 9 Interestingly, our study showed that females had higher occurrence of TP and tended to have more medium-and largesized TP than males, while the results were demonstrated vice versa for TM.…”

“…They may also interfere with the construction and function of removable dentures, as well as oral functional movement. 2 The prevalence of tori varies widely in different populations, ranging from 0.4 % to 66.5% for TP [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] and 0.5% to 63.4% for TM. 3, 6-7, 9-12, 15-17 Racial differences appear significant, with a high prevalence in Asian and Eskimo populations.…”

The aims of this study were to determine the prevalence, size, shape, and location of torus palatinus (TP) and torus mandibularis (TM), and to investigate their sex-and age-related differences in a Thai population. One thousand two hundred subjects were examined for the presence of both tori at the Faculty of Dentistry, Chulalongkorn University. The prevalence for TP and TM in the subjects was 58.1% and 31.9%, respectively. TP were significantly more common in females than in males (67.3% versus 48.8%; p<0.001). TP were frequently found in small and medium sizes, spindle-shaped and often located at the combined premolar to molar and molar areas. The prevalence of TM was higher in males than in females (34.8% versus 29.0%; p=0.030). TM occurred most commonly in small size, bilateral multiple form, and was often located at the canine to premolar area. There was a significant correlation between the prevalence of both tori and age (p<0.001 for TP and p=0.004 for TM). The prevalence of both tori in this Thai population were comparable to the Mongoloids and other Asian populations. Statistically significant differences in the prevalence and size of tori in regard to sex and age were also found.

“…6). Though recognized the presence of palatine torus in a fetal palate, Miller and Roth (1940) conclude that palatine torus is rare under the age of five and generally makes its appearance around age seven. find that both frequency and expression increase in Icelandic schoolchildren from the ages of six to 17 years.…”

“…Most researchers report that palatine torus is more prevalent in females than males (Austin et al, 1965;Balaez et al, 1983;Miller and Roth, 1940;Lasker, 1947Lasker, ,1950Moore, 1971,1976;Ohno et al, 1988;Sakai, 1954;van den Broek, 1943;. However, some authors find no difference between the sexes De Villiers, 1968) or find a higher frequency in males (Bernaba, 1977;Hrdlicka, 1940).…”

Physical anthropologists have long been intrigued by the distinctive oral tori expressed by the medieval Norse populations of Iceland and Greenland. To assess the temporal and spatial variation of one form of oral tori, palatine torus, observations were made on all available Greenlandic Norse skeletons, as well as on samples of medieval Icelanders and Norwegians. In terms of temporal variation, 12th to 14th century (medieval) Greenlanders from the Eastern and Western settlements exhibited higher frequencies and more pronounced expressions of palatine torus compared with early 11th century Greenlanders. The early Greenlandic sample closely approximated the medieval Icelandic and Norwegian samples for total torus frequency, although the Norwegians exhibited the trait to a less pronounced degree. As degree of expression is the most distinctive aspect of torus variation among the Norse, some combination of environmental factors, including increased masticatory stress and chronic undernutrition, probably accounts for most of the difference between settlement period and medieval Greenlanders. Although palatine torus may be hereditary in part, environmental factors play a significant role in the expression of this trait.
