     [摘要]目的:获得个别正常牙合 舌体形态的测量数据并探明舌体大小与牙弓的相关关系。方法:建立舌体超声定位测量分析系统,在定位系统的引导下,通过超声自带软件测量舌体不同断面的测量指标的测量值,并对其相对应的牙弓进行测量获得牙弓长度及牙弓宽度的测量值,计算舌/牙弓比值。舌体与身高、体重、头围作相关与回归分析,并对r值作有效性检检。舌体测量值为自变量,牙弓测量值为应变量,进行相关与回归分析。结果:获得了汉族个别正常牙合青年舌体大小测量结果,并明确舌体厚度无性别差异(P>0.05),后部舌宽度性别差异显著(P<0.05),前部舌长度无性别差异(P>0.05),其余长度测量项目男性大于女性(P<0.05)。舌体宽度与对应牙弓宽度有较强相关性(P<0.05),舌体长度与对应牙弓长度有较强相关性(P<0.05),舌/牙弓比值范围在0.773~0.863之间。结论:舌体形态大小与牙弓形态大小有较强的相关关系。

    Abstract:ObjectiveTo investigate tongue size information of the individual normal occlusion and to investigate the correlation between the tongue size and dental arch size.MethodsWe set up tongue localization measurement to figure out the normal data of individual normal occlusion by using ultrasonic soft ware. Dental casts were measured by auto gauge. Tongue/dental arch rate was calculated. Correlate and Regression analysis was applied to analyse tongue size and dental arch size or height or weight or head diameter.ResultsWe got the data of normal tongue size. The posterior tongue width difference between male amd female was significant. Most length measurements were different between male and female. The correlationship between tongue size and dental arch was significant and the rate was 0.773~0.863.ConclusionsThe correlation between tongue and dental arch are significant.

    Key words: tongue,dental arch, tongue/dental arch rate, correlate and regression

    舌体位于固有口腔内并与下颌牙弓相毗邻,其形态大小及运动的异常被认为与某些牙颌畸形密切相关[1]。因此,舌体形态大小与其周围组织结构间的相互关系一直是口腔医学界的研究热点问题。多年来 ......
