2、MI的相关性。结果:受试者总体在牙长轴纵切面上,中切牙、侧切牙和尖牙唇侧龈缘至牙槽嵴顶的黏膜厚度(mm)分别为1.32±0.20、1.10-4-0.24、1.21±0.19;牙槽嵴顶至其根方3mm范围的黏膜厚度(mm)分别为0.69±0.17、0.52±0.16、0.59±0.15;牙龈宽度(mm)分别为3.18±0.45、3.00±0.44和3.07±0.40。上颌前牙唇侧牙槽嵴顶至其根方3mm范围的黏膜厚度男性大于女性(P<0.05),与黏膜厚度BMI显著正相关(r=0.376,P<0.05)。结论:①上颌前牙区唇侧牙龈厚度呈冠根向递增趋势,唇侧牙龈厚度大于牙槽黏膜厚度;②男性牙槽黏膜
3、厚度显著大于女性;③牙槽黏膜厚度与体质量指数显著正相关。[关键词]锥束计算机体层摄影术;口腔黏膜;牙龈;测量[中图号]R781[文献标识码]A[文章编号]1005—2593(2014)06—0350—05[牙体牙髓牙周病学杂志,2014,24(6):350]Thicknessoflabialgingivaandmucosaatmaxillaryanteriorteethmeasuredbycone-beamCTSHISu-meng,SHISheng-gen,BAIZhong-cheng,YanShu,WUBao-jiang(306HospitalofP,AnhuiMedicalUnive~
