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.
本研究的目的是调查由副功能活动（紧咬牙和磨牙）所表明的口腔隆突与咬合应力之间的关系，并报告泰国南部一所牙科医院就诊患者中腭隆突（TP）和下颌隆突（TM）的患病率。对609名个体（183名男性和426名女性）进行了访谈，并检查了他们是否有紧咬牙和磨牙习惯。还对每个个体检查了TP和TM的存在情况，对于TM记录了其大小。进行列表分析以找出副功能、年龄和性别与TP或TM存在之间的粗略关系。然后通过逻辑回归分析这些关系。在这些个体中，376人（61.7%）有TP，而182人（29.9%）有TM。TP和TM的男女患病率之比分别为1:1.4和1:0.94。因此，TP在女性中更常见。发现紧咬牙和磨牙与TM的存在之间有很强的关联。TM的存在可能有助于作为寻找副功能迹象的线索。
