摘要
目的:探讨牙髓电活力差值对因深龋引起的可复性牙髓炎(RP)和有症状不可复性牙髓炎(SIRP)的诊断能力。方法:选取龋源性牙髓炎患者370例,记录一般信息和临床检查结果,将其分为两组:RP组202例,SIRP组168例。测试患牙和对照牙的牙髓电活力值并计算差值,单因素分析年龄、性别和牙齿类型是否为混杂因素,构建模型后采用Logistic回归及限制性三次立方样条函数分析牙髓电活力差值与牙髓炎诊断的关系。结果:单因素分析显示,年龄与牙髓电活力差值相关(P<0.05),牙齿类型与牙髓炎诊断相关(P<0.05),最终将年龄和牙齿类型纳入混杂因素。未校正混杂因素、依次校正年龄和牙齿类型后构建3个模型,RP组和SIRP组的电活力差值具有统计学意义(OR=1.041、1.041、1.041,95%CI:1.017~1.065、1.018~1.066、1.017~1.066,均P<0.05)。限制性三次立方样条函数结果显示随着电活力差值增大,罹患SIRP的风险也随之增加(P<0.05)。3种模型的曲线下面积分别为0.599、0.598、0.602。结论:牙髓电活力差值有助于RP和SIRP的鉴别诊断。
Objective:To investigate the diagnostic ability of the difference in electric pulp test values for the reversible pulpitis(RP)and symptomatic irreversible pulpitis(SIRP)caused by deep caries.Methods:A total of 370 patients diagnosed with cariogenic pulpitis were selected.General information and clinical examination data were collected.The patients were divided into two groups:RP group(202 cases)and SIRP group(168 cases).The electrical pulp activity values of affected and control teeth were tested and the difference values were calculated.Univariate analysis was performed to determine whether age,sex and tooth type were confounding factors.After the three models were established,Logistic regression and restricted cubic spline function were used to analyze the relationship between the difference of pulp electrical activity and diagnosis of pulpitis.Results:Univariate analysis showed age was correlated with the difference in electric pulp test values(P<0.05),and tooth type was correlated with the diagnosis of pulpitis(P<0.05).Finally,ageand tooth type were included as confounding factors.Three models were established without adjusting for confounding factors and after adjusting for age and tooth type in turn.The difference in electric pulp test values between the RP and SIRP groups was statistically significant(OR=1.041,1.041,1.041,95%CI:1.017-1.065,1.018-1.066,1.017-1.066,all P<0.05).The results of the restricted cubic spline function showed that the risk of SIRP increased with the increase of the electrical activity difference(P<0.05).The AUC of the three models were 0.599,0.598,0.602,respectively.Conclusion:The difference in electric pulp test values is helpful for the differential diagnosis of RP and SIRP.
