Abstract

OBJECTIVE

To examine the prevalence of torus mandibularis (TM) and identify clinical factors associated with its presence.

MATERIALS AND METHODS

A total of 664 Japanese adults over age 60 were studied by means of a questionnaire and clinical examination.

RESULTS

In all, 197 subjects (29.7%) had TM. We found a significant association between the presence of TM and torus palatinus (TP; 45.1% vs. 26.5%, p<0.001). Moreover, occlusal force with TM was significantly higher than without TM (p<0.05). Logistic regression adjusted for age and occlusal force revealed a significant relationship between TM and occlusal force and TP [p=0.005, odds ratio (OR)=2.44; p<0.001, OR=2.66, respectively].

CONCLUSION

This study suggests that there is a relationship between TM and factors related to occlusal factor.

摘要

目的

研究下颌隆突（TM）的患病率，并确定与其存在相关的临床因素。

材料与方法

通过问卷调查和临床检查对664名60岁以上的日本成年人进行了研究。

结果

共有197名受试者（29.7%）有TM。我们发现TM的存在与腭隆突（TP）之间存在显著关联（45.1%对26.5%，p<0.001）。此外，有TM者的咬合力明显高于无TM者（p<0.05）。经年龄和咬合力调整的逻辑回归显示，TM与咬合力和TP之间存在显著关系[p=0.005，优势比（OR）=2.44；p<0.001，OR分别为2.66]。
