摘要/Abstract

摘要： 【摘要】目的研究成年人最大开口度(MMO)不同性别差异及与身高、体质量间的相关性。方法随机选取142名18～26岁的成年人，使用数显游标卡尺测量受试者最大张口状态时上下颌同名中切牙切缘间的垂直距离。所有操作均由同一位医师完成。运用独立样本t检验和单因素方差分析不同性别最大开口度的差异，Pearson相关性分析身高、体质量与最大开口度间的相关性，并建立相应的回归模型。结果最大开口度为(53.11±5.61)mm，其中男性(56.56±5.08)mm显著大于女性(49.55±3.54)mm，P﹤0.00。身高(H)、体质量(W)与最大开口度的Pearson相关系数分别为0.67、0.71，回归方程分别为最大开口度=0.49H-30.92、最大开口度=0.30W+33.57。结论最大开口度存在着性别差异，身高和体质量均存在显著相关性。

Abstract: Abstract: Objective To study sex difference of maximum mouth opening(MMO) in adults and its correlations with height and weight. Methods 142 adults aged 18-26 were randomly selected. The vertical distance between the incisal edges of central incisors with the same name of maxillary and mandibular under maximum mouth opening status was measured with digital vernier caliper. All operations were performed by the same physician. The sex difference of MMO was analyzed by independent sample t test and one-way ANOVA. The correlation of MMO with height and weight was estimated by Pearson correlation analysis, followed by simple linear regression models being established. Results The MMO of those subjects selected in this study was (53.11±5.61)mm and the MMO of males (56.56±5.08)mm was significantly larger than that of females (49.55±3.54)mm，P﹤0.00. The Pearson correlation coefficients of MMO with height and weight were 0.67 and 0.71 separately. The regression equation: MMO=0.49H-30.92、MMO=0.30W+33.57. Conclusions Sex has a significant influence on the MMO values of adults. There are significant correlations between height and weight.
