问题的陈述。切牙磨损可能是长期磨牙行为的标志。磨牙症被认为是颞下颌关节紊乱病（TMD）的一个危险因素。本研究旨在探讨前牙磨耗与颞下颌关节紊乱病的关系。208名TMD患者和172名对照者被选入研究。在排除了对侧牙弓中有1个以上前磨牙或磨牙区缺失的受试者以及前牙缺失或严重修复的受试者后，154名TMD患者和120名对照受试者被纳入研究（年龄31.2 ± 13.4岁;范围13至76岁）。前牙磨损在石膏上以0至5级进行评估。控制年龄和性别的影响，进行多元Logistic回归分析，以探讨牙齿磨损和TMD之间的关系。比值比为0.76（95%置信区间：0.51 ~ 1.15），表明在调整性别和年龄后，平均牙齿磨损评分每增加一个单位，有利于TMD的比值估计减少24%。该结果不具有显著性（P= 0.20）。在本研究的限制范围内，当控制年龄和性别的影响时，切牙磨损（通过牙模评估）与TMD无显著相关性。基于这些发现，可以排除切牙磨损导致TMD的临床相关风险。因此，现有证据不支持治疗切牙磨损可预防TMD的观点。
Statement of problem. Incisal tooth wear may be a sign of long-term bruxing behavior. Bruxism is Purported to be a risk factor for temporomandibular disorders (TMD).Purpose. The purpose of this clinic-based case-control study was to investigate whether the wear of anterior teeth is associated with TMD.Material and methods. Two hundred eight TMD patients and 172 control subjects were selected for participation. After exclusion of subjects with more than 1 missing premolar or molar zone in opposite arches, as well as subjects with missing or severely restored anterior teeth, 154 TMD patients and 120 control subjects were included in the study (age 31.2+/-13.4 years; range 13 to 76 years). Anterior tooth wear was assessed on casts with a 0 to 5 scale. A multiple logistic regression analysis, controlling for the effects of age and gender, was performed to investigate the relationship between tooth wear and TMD.Results. An odds ratio of 0.76 (95% confidence interval: 0.51 to 1.15) indicated that after adjusting for gender and age, the odds in favor of TMD decreased an estimated 24% for each additional unit of the mean tooth wear score. This result was not significant (P=.20).Conclusion. Within the limitations of this study, incisal tooth wear (assessed on dental casts) was not significantly associated with TMD when the influence of age and gender was controlled, Based on these findings, a clinically relevant risk for TMD from incisal tooth wear can be excluded. Hence, the presented evidence does not support the idea that treatment of incisal tooth wear is indicated to prevent TMD.
