摘　　要：目的 探讨成都地区藏族与汉族人群前牙区牙体及牙弓形态的性别与民族差异,为个性化口腔治疗和咬痕检测提供参考。方法 选取2024年5-12月四川省人民医院就诊的健康藏族和汉族成人各26例,采用3Shape Ortho System对前牙区牙体及牙弓形态进行测量分析。结果 藏族与汉族牙冠宽度、厚度及牙弓形态存在性别差异,男性>女性,特别是藏族下颌中切牙牙冠宽度及上颌尖牙牙冠厚度差异有统计学意义(P<0.05);藏族的牙冠宽度和厚度<汉族,且藏族女性在上颌中切牙和尖牙牙冠宽度、上颌尖牙牙冠厚度的差异有统计学意义(P<0.05)。前牙区牙弓宽度上,藏族女性上颌<汉族,下颌>汉族;藏族男性上颌>汉族,下颌<汉族。结论 藏汉族在前牙区牙体及牙弓形态上存在性别与民族差异,临床口腔治疗和咬痕印迹分析应结合族群特点制定个性化方案。Objective This study aimed to provide references for personalized dental treatment and bite mark analysis by measuring the morphology of anterior teeth and dental arches in Tibetan and Han populations.Methods Healthy Tibetan and Han adult patients in Sichuan Provincial People's Hospital from May 2024 to December 2024 were selected,and the morphology of anterior teeth and dental arches was measured using the 3Shape Ortho System.Results Gender differences were generally observed in crown width,crown thickness,and anterior dental arch width,with males showing larger measurements than females.Significant differences were found particularly in the crown width of the mandibular central incisors and the crown thickness of the maxillary canines in the Tibetan population(P<0.05).Ethnic comparison revealed that the crown width and thickness of the Tibetan population were generally smaller than those of the Han population.Tibetan females exhibited particularly significant differences in crown width of the maxillary central incisors and canines,as well as crown thickness of the maxillary canines(P<0.05).Regarding the anterior dental arch width,Tibetan females had a smaller maxillary arch but a larger mandibular arch compared to Han females.Tibetan males had a larger maxillary arch but a smaller mandibular arch than their Han counterparts.Conclusion Significant gender and ethnic differences exist in the morphology of anterior teeth and dental arches between Tibetan and Han populations.Clinical dental treatment and bite mark analysis should consider these ethnic characteristics to develop personalized treatment plans.
