191例福建居民上颌前牙解剖长度及宽度分析

Characteristics of maxillary anterior teeth of 191 individuals living in Fujian Province

目的:通过锥形束CT(cone-beam CT,CBCT)测量分析,了解福建居民上前牙解剖学特征,为进行上颌前牙区修复提供参考。方法:利用CBCT测量191例就诊于福建医科大学附属口腔医院门诊患者的1146颗上前牙(中切牙、侧切牙、尖牙)各牙位的长度及宽度,根据性别进行分组,量化分析牙体解剖特征的参数比例(宽长比及宽度比)。采用SPSS 19.0软件包对数据进行统计学分析。结果:男性中切牙、尖牙的宽度和长度大于女性,差异有统计学意义(P<0.05),男性、女性侧切牙的宽度和长度无显著差异(P>0.05);男性、女性上颌前牙的宽长比值无显著差异(P>0.05),宽度比值差异有统计学意义(P<0.05)。结论:临床上应充分考虑患者地区、种族及性别差异,以更好地进行上颌前牙修复。

PURPOSE:To investigate the anatomical characteristics of upper anterior teeth of residents in Fujian province using cone-beam CT(CBCT).METHODS:The length and width of 1146 maxillary anterior teeth(central incisors,lateral incisors,and canines)from 191 patients were measured.SPSS 19.0 software package was used to analyze the data.RESULTS:The width and length of males’maxillary central incisors and canine were significantly greater than those of females(P<0.05).No significant difference was found in the width and length of maxillary lateral incisors between genders(P>0.05).No significant difference was found in the width-length ratio of maxillary anterior teeth between genders(P>0.05).Significant difference was found in the width-width ratio of maxillary anterior teeth between genders(P<0.05).CONCLUSIONS:Varied anatomical characteristics of the maxillary anterior teeth of residents in Fujian Province should be observed between genders.
