摘要
目的:本研究比较了不同牙位、民族的冠龈特征,并分析牙周生物型特征及其相关影响因素。方法:随机调查我国新疆石河子地区4个民族(汉族、维吾尔族、哈萨克族、回族)335名口腔健康人群的牙周生物型特征。通过临床和模型测量获得上颌前牙牙龈生物型(GB)、牙冠宽度(CW)、牙冠长度(CL)、牙冠宽长比(CW/CL)、附着龈宽度(AGW)和探诊深度(PD)。据调查问卷评价GB与性别、种族、吸烟状况、饮酒、体重指数(BMI)、刷牙习惯及漱口水使用的相关性。结果:上颌前牙区不同牙位CW、CL、CW/CL、AGW存在显著差异;不同牙位的GB分布存在显著差异,中切牙、侧切牙和尖牙的厚龈型分别占60.1%、37.9%和26.1%(P<0.001)。不同民族CL、CW/CL和AGW均存在差异(P<0.05)。男性和少数民族(维族、哈族)厚龈型明显多于女性和汉族;吸烟、高BMI(18.5 kg/m^(2)≤BMI<25 kg/m^(2),BMI≥25 kg/m^(2))人群侧切牙具有较多的厚龈型;饮酒、横纵刷牙方式结合的人侧切牙具有较多的薄龈型(P<0.05)。结论:冠龈形态在不同牙位、种族在上有显著差异。且与GB相关的因素中,性别和民族在本研究中表现出更高相关性。
Objective:To assess the morphological characteristics of different tooth sites,sex,and ethnic groups,and evaluate their correlation to gingival biotype(GB).Methods:Periodontal phenotypes in 335 healthy individuals from four ethnic groups in the Xinjian region of China were investigated.Clinical and dental stone measurements were used to establish the crown width(CW)and length(CL)and its ratio,attached gingival width(AGW),and probing depth(PD).GB association with sex,ethnic group,smoking status,alcohol consumption,BMI,toothbrushing habits and patterns,and mouthwash use,was evaluated.Results:CW,CL,CW/CL,and AGW among maxillary anterior teeth were different significantly(P<0.001).There were significant differences in the distribution of GB in different teeth positions(P<0.001).The thick gingival biotypes were 60.1%,37.9%,and 26.1%in incisors,lateral incisors,and canines,respectively(P<0.05).There were differences in CL,CW/CL ratio and AGW in different ethnic groups(P<0.05).The thick gingiva biotype of maxillary anterior teeth was more in male and Uygur and Kazakh ethnic group.People with smoking manner and higher BMI(18.5 kg/m^(2)≤BMI<25 kg/m^(2),BMI≥25 kg/m^(2))had more thick gingival biotypes.There were more thin gingival biotypes in the group of drinking and brushing vertically and horizontally(P<0.05).Conclusion:Significant differences were found in dentogingival measurements according to tooth position and ethnicity.Factors related to GB according to tooth position varied significantly,but sex and ethnicity had marked effects.
