摘要/Abstract

摘要： 目的：探讨引起楔状缺损的危险因素。方法：应用Teetester咬合分析系统对30例患者的420颗上颌牙齿进行咬合观测，记录早接触患牙、分离时间及力百分比，通过统计学方法分析楔状缺损的危险因素。结果：上颌各类楔状缺损患牙中，前磨牙占比最高，为46.49%；64颗早接触牙齿中42颗伴有楔状缺损，经卡方检验，Pearsonχ2=25.732，P<0.001，OR=4.0，95% 置信区间（2.282~7.015），提示早接触与楔状缺损的发生有统计学意义；26颗分离时间过长牙齿中17颗伴有楔状缺损，经卡方检验，Pearsonχ2=9.285，P<0.05，OR=3.427，95%置信区间（1.489~7.890），提示分离时间与楔状缺损的发生有统计学意义；对比41颗楔状缺损患牙与对侧同名正常牙所受力大小，差异具有统计学意义（P<0.05）；对比43颗楔状缺损深度较深的患牙与对侧楔状缺损深度较浅的同名患牙所受力大小，差异具有统计学意义（P<0.05）。结论：上颌前磨牙区是楔状缺损的易患区域；早接触、分离时间及力大小是楔状缺损的危险因素。

Abstract: Objective To study the risk factors of wedge-shaped defects. Methods Thirty patients with total 420 maxillary teeth were selected. And the Teetester occlusal analysis system was employed to record premature contact teeth, disocclusion time (DT) and occlusal force through which the risk factors were thus statistically revealed. Results Among the maxillary teeth, premolars occupied 46.49%, which illustrates that the maxillary premolar region is the susceptible area of wedge-shaped defects. Among 64 premature contact teeth, 42 were defected teeth, according to Chi-square statistics, Pearsonχ2=25.732, P<0.001, OR=4.0, 95% Confidence interval (2.282~7.015), which illustrates that premature contact is a risk factor. Moreover, among 26 over disocclusion time teeth, 17 were defected teeth, according to Chi-square statistics, Pearsonχ2=9.285, P<0.05, OR=3.427, 95% Confidence interval (1.489~7.890), which illustrates that disocclusion time is another risk factor. The difference of occlusal force between 41 defected teeth and normal teeth were obvious (P<0.05). And the difference of occlusal force between 43 pairs of deeper defected teeth and lighter defected teeth were obvious (P<0.05) too. Conclusion The maxillary premolar region is the susceptible area of wedge-shaped defects. Premature contact teeth, disocclusion time, and occlusal force are risk factors.

Key words: Wedge-shaped defects, Premature contact, Disocclusion time
