          Abstract

          Objectives

          The objectives of this study were to determine the prevalence, size, shape and location of the torus palatinus (TP) in dental outpatients in Cappadocia region of Turkey and to investigate the relationship between the findings in relation to age and gender.

          Methods

          The present study included 2660 patients, who attended the Department of Oral Diagnosis and Radiology in the Faculty of Dentistry at Erciyes University for their dental problems between December 2005 and May 2007. The presence or absence of TP was examined by clinical inspection and palpation.

          Results

          The prevalence of TP in our large sample was low (4.1%) in comparison to other Turkish population. It was found to be significantly higher (P<.001) in females (5.7%) than in males (1.8%). Most TP were found in flat shape (62.7%), smaller than 2 cm (75.4%) and located at premolar-molar region (66.4%).

          Conclusions

          This study indicated that the prevalence of TP in Turkish population was low. Our results showed a significant relationship between the occurrence of TP and gender. According to the literature, it was firstly showed that flat TP was the most common type in our large population.

          Palatine and mandibular tori. A morphologic study in the current Norwegian population.

          De Haugen (1992)
          Five thousand Norwegians, 2783 females and 2217 males, ranging in age from 16 to 89 years, have been screened for the presence of torus palatinus and/or torus mandibularis and analyzed with regard to size and shape of tori, sex, and age. The tori have been classified according to size as small, medium, and large. No measurements have been made, consistent with the view that these characteristics are non-metrical and should be assessed by means of a standard procedure. The prevalence figures of both tori were fairly low, in accordance with former reports. In torus palatinus there was female predominance, with a sex ratio of 5:3. In torus mandibularis the males were in majority, and the sex proportion was 4:3. In both sexes prevalence of the two tori was highest in the 35- to 65-year age group. Further analysis indicated in both tori a real correlation between prevalence and size and some correlation also between size and shape of torus palatinus but not of torus mandibularis. The figures of concurrence of the two tori were low, denoting a non-significant correlation. Still, the analysis showed that each torus occurred more than twice as frequently in an individual bearing the other torus. Torus morphoanalysis, explaining diverging patterns of clinical conduct in the two tori, and the relative weight of hereditary versus environmental factors as morphogenetic determinants of the condition, including a quasi-continuous genetic or threshold model, have contributed to shed new light on the torus phenomenon. The occurrence and propagation of torus mandibularis complies reasonably well with this model, and the present analysis indicates that even torus palatinus should appropriately be considered a threshold character.

            Prevalence of torus palatinus and torus mandibularis in Germans and Thai.

            Torus palatinus (TP) was recorded in 13.5% of 1317 German patients (606 men, 711 women). There was no statistically significant difference between the sexes. Torus palatinus was found in 23.1% of 947 Thai (404 men, 543 women). The difference between the sexes was significant (P less than 0.001); women were affected in 28.5%, men showed a TP in 15.8%. The differences in prevalence rates between Germans and Thai was also statistically significant (P less than 0.001). Torus mandibularis (TM) was recorded in 5.2% of the German patients with 8.6% of the men and 2.4% of the women being affected (P less than 0.001). In the Thai, 9.4% of the men and 9% of the women showed TM. The difference between the prevalence rates in Germans and Thai was significant (P less than 0.001). While generally milder forms of tori were observed in German patients, marked forms of TM were also seen in this group. While the etiology of TP and TM is still no quite clear, racial factors must definitely be considered.

              A clinical study of oral tori in southern Thailand: prevalence and the relation to parafunctional activity.

              The objective of the present study was to investigate the relationship of oral tori and occlusal stress as indicated by parafunctional activity (clenching and grinding) and to report the prevalence of torus palatinus (TP) and torus mandibularis (TM) among patients attending a dental school hospital in southern Thailand. Six-hundred-nine individuals, 183 males and 426 females, were interviewed and examined for the presence of clenching and grinding habit. The presence of TP and TM was also examined in each individual and in the case of TM size was recorded. Tabulated analysis was carried out to find the crude relationships of the parafunction, age and sex to the presence of TP or TM. The relationships were then analyzed by logistic regression. Of these individuals, 376 (61.7%) had TP, whereas 182 (29.9%) had TM. The male:female prevalence ratios of TP and TM were 1:1.4 and 1:0.94, respectively. TP was, thus, more frequent in females. A strong association between clenching and grinding and the presence of TM was found. The presence of TM might be useful as a cue to look for signs of parafunction.
