摘　　要：目的评估上颌中切牙牙槽骨厚度与牙周组织破坏的关系。方法随机选取99颗上颌中切牙,记录牙齿唇侧、腭侧、近中、远中四个位点牙周袋探诊深度(PD)、临床附着丧失(CAL)、出血指数(BI);锥形束CT(CBCT)测量牙齿釉质牙骨质界(CEJ)下4、6、8 mm处唇侧牙槽骨厚度(LBT)、腭侧牙槽骨厚度(PBT)、近中牙槽骨厚度(MBT)、远中牙槽2018-05-03接收骨厚度(DBT);统计学分析牙槽骨厚度与牙周临床指标的相关性。结果上颌中切牙CEJ下4、6、8 mm处LBT、PBT、MBT、DBT分别与CAL、BI呈负相关性(P<0.05),与PD无相关性(P>0.05)。结论上颌中切牙牙槽骨厚度与牙周组织破坏有一定的相关性,牙槽骨厚度可能作为一种局部解剖因素在牙周炎的发生、发展中起一定的促进作用。Objective To evaluate the relationship between alveolar bone thickness and periodontal breakdown of maxillary central incisors.Methods Ninety-nine maxillary central incisors were randomly enrolled in the study,at four sides(labial,palatal,mesial and distal)per tooth,probing depth(PD),clinical attachment level(CAL),bleeding index(BI)were measured.Labial bone thickness(LBT),palatal bone thickness(PBT),mesial bone thickness(MBT),distal bone thickness(DBT)were respectively measured at 4,6,8 mm from the CEJ by cone beam computed tomography(CBCT).Statistical analysis was made to detect the relationship between alveolar bone thickness and periodontal clinical measurements.Results LBT,PBT,MBT,DBT at 4,6,8 mm from the CEJ were negatively related to CAL and BI except PD(P<0.05).Conclusion The thickness of alveolar bone in maxillary central incisors has a certain correlation with periodontal tissue destruction.Alveolar bone thickness may play a role in the occurrence and development of periodontitis as a local anatomical factor.
