牙髓塑化治疗后再治疗原因分析

目的对临床上需要再治疗的牙髓塑化治疗病例进行分析，探讨牙髓塑化治疗病例再治疗的原因，为牙髓塑化治疗效果评价提供临床依据。方法随机选取已做牙髓塑化治疗但需再治疗的患牙296例，记录患者一般情况、就诊原因、牙位、塑化时间以及患者年龄。结果牙髓塑化治疗后再治疗的主要原因为牙折，占30．41％，其次是充填物脱落（26．01％）和慢性根尖周炎（20．95％）。296例牙髓塑化治疗病例中再治疗牙齿69．59％为磨牙；牙髓塑化治疗5年后需要根管再治疗的牙齿占84．12％；年龄方面再治疗患者以30岁至60岁为主，占总数的64．19％。结论牙折、充填物脱落和慢性根尖周炎是导致牙髓塑化治疗再治疗的主要原因，牙髓塑化治疗远期疗效不理想。

Analysis of causes for retreatment of resinified teeth

Objective To analyze the reasons for retreating resinified teeth and the factors that may lead to the failure of resinified teeth.MethodsA total of 296 failed resinified teeth were randomly selected and included in this study.The causes of failure,tooth position,resinified duration and the age of the patient were recorded and the data analyzed.ResultsTeeth fracture accounted for 30.41%,which was the major cause for retreatment,followed by missing of fillings(26.01%)and chronic apical periodontitis(20.95%).69.59% were molars;84.12% of the teeth which needed retreatment had received resinifying treatment for 5-10 years;64.19% of the resinified teeth were from 30-60 years old patients.ConclusionMissing of restoration and teeth fracture were the main causes for the retreatment of resinified teeth.Long-time results of resinifying treatment were not good.
