牙周炎患者临床探诊深度与牙槽骨吸收程度的相关性分析

Correlation between clinical probing depth and alveolar bone resorption in patients with periodontitis

目的:探究牙周炎患者临床探诊深度(CPD)与牙槽骨吸收程度的相关性。方法:纳入2018年2月—2020年12月在天津医科大学口腔医院牙周科就诊的105例牙周炎患者,搜集患者的一般资料、第一磨牙的CPD和第一磨牙牙槽骨吸收程度的锥形束计算机断层扫描(CBCT)影像学数据。用Pearson相关分析研究CPD与牙槽骨吸收程度的相关性。结果:“轻度牙槽骨吸收组”与“重度牙槽骨吸收组”仅年龄(t=-2.147,P=0.034)和CPD(t=-2.941,P=0.004)差异具有统计学意义;二元Logistic回归纳入年龄这一混杂因素,校正后CPD每增加1 mm,牙槽骨吸收程度加重发生的概率为72.1%(P=0.002);简单效应分析显示年龄与CPD之间交互作用显著(P=0.000)。用年龄(≤45岁为青壮年,>45岁为中老年)和牙槽骨吸收程度进行分层,“青壮年轻度牙槽骨吸收组”CPD与牙槽骨吸收程度呈中度正相关(r=0.5795,P=0.0012),“青壮年重度牙槽骨吸收组”CPD与牙槽骨吸收程度呈中度正相关(r=0.4047,P=0.0216),“中老年轻度牙槽骨吸收组”CPD与牙槽骨吸收程度不相关(r=0.2322,P=0.4452),“中老年重度牙槽骨吸收组”CPD与牙槽骨吸收程度不相关(r=0.08201,P=0.6554)。结论:CPD可以在一定程度上反映患者牙槽骨的破坏程度,尤其是45岁以下的青壮年牙周炎患者。

Objective:To study the correlation between clinical probing depth(CPD)and alveolar bone resorption in patients with periodontitis.Methods:A total of 105 patients with periodontitis in the Department of Periodontal of Stomatological Hospital of Tianjin Medical University from February 2018 to December 2020 were included.The general data,CPD and cone beam computed tomography(CBCT)imaging data of the alveolar bone absorption degree of the first molar were collected.Pearson correlation analysis was performed to study the correlation between CPD and alveolar bone resorption.Results:There were significant differences between the"mild alveolar bone resorption group"and the"severe alveolar bone resorption group"only in age(t=-2.147,P=0.034)and CPD(t=-2.941,P=0.004);Binary Logistic regression included age as a confounding factor.The probability of aggravating alveolar bone resorption was 72.1%for every 1 mm increase in CPD after correction(P=0.002).Simple effect analysis showed that the interaction between age and CPD was significant(P=0.000).Stratified by age and alveolar bone resorption,young adults were less than or equal to 45 years old,and middle-aged and elderly people were more than 45 years old.CPD in the"young adults and mild alveolar bone resorption group"was moderately positively correlated with alveolar bone resorption(r=0.5795,P=0.0012),CPD was moderately positively correlated with alveolar bone resorption in the"young adults and severe alveolar bone resorption group"(r=0.4047,P=0.0216),there was no significant correlation between CPD and alveolar bone resorption in the"mild alveolar bone resorption in the middle-aged and elderly group"(r=0.2322,P=0.4452),and there was no significant correlation between CPD and alveolar bone resorption in the"severe alveolar bone resorption in the middle-aged and elderly group"(r=0.08201,P=0.6554).Conclusion:CPD can reflect alveolar bone resorption to a certain extent especially young adults with periodontitis under 45 years old.
