Variation in torus palatinus prevalence in Norway

Abstract

The variation in lorus palatinus (TP) prevalence was investigated among a total of 2010 denial patients over 10 yr of age native to two different regions in Norway, the Lofoten Islands in northern Norway and the Gudbrandsdalen valley, an inland area in the southeastern part of the country. The two groups were presumed to belong to the same Caucasian stock, but were extremes with regard to the fish‐to‐meat ratio of the diet, which was 3:1 in Lofoten and 1:3 in Gudbrandsdalen, respectively representing a soft type of diet, and a tough type requiring greater muscular forces during mastication. The study revealed: 1) the prevalence of TP was higher among women than men; 2) TP seemed likely to arise from a multifactorial liability, with part of the genetic factors residing on the X chromosome; 3) the prevalence of TP appeared to be higher among natives of Lofoten, who consume the softer food, than among natives of Gudbrandsdalen, the higher prevalence being hypothesized to have some connection with nutrient substances present in saltwater fish, possibly Ω3 polyunsaturaled fatty acids and vitamin D; and 4) TP seemed to be a dynamic phenomenon capable of growth and subject to resorption remodeling.

Surgical management of palatine Torus - case series

“…The literature shows the majority frequency of TP in women 19,20 , probably because it seems to be a dominant type of TP linked to the X chromosome 2 .…”

“…In the majority of the studies, palatine torus is more frequent than mandibular torus 6,11,14,20,22,23 and concurrence appears to happen in about 2-3% of cases 20 .…”

Oral Tori In Edentulous Patients

“…7 Differences in the prevalence of tori between genders have also been reported. Most authors reported that TM was more frequent in males 7,8 while TP affected more females than males. 8,9 The occurrence of tori in various ethnic groups ranges from 9% to 66%.…”

“…4 The prevalence of tori varies widely in different populations, ranging from 0.4% to 66.5% for TP 5 and 0.5% to 63.4% for TM. [5][6][7] Racial differences appear significant, with a high prevalence in Asian and Eskimo populations. 7 Differences in the prevalence of tori between genders have also been reported.…”
