慢性根尖周炎进行一次性根管治疗术的临床观察

目的:探讨慢性根尖周炎患者进行一次性根管治疗术的急性发作原因和预防措施。方法:慢性根尖周炎共182例,男性84例,女性98例,年龄12岁～75岁。所有病例均应用TRIAUTO-ZX全自动根管治疗仪进行一次性根管治疗。结果:急性炎症的发作率为17.03%。女性急性发作率为17.34%,男性为16.67%(P>0.05)。12岁～34岁急性发作率为20.31%,35岁～54岁为17.95%,55岁～75岁为17.64%,(P<0.05)。前牙急性发作率为14. 71%,前磨牙为15.56%,磨牙为17.43%(P>0.05)。器械穿出根尖孔者,急性发作率45.45%,未穿出根尖者为13. 12%(P<0.05)。超填者的急性发作率为28.57%,未超填的急性发作率为16.57%(P>0.05)。结论:患者个体内在因素、患牙的解剖病理因素以及术者的治疗和操作是慢性根尖周炎进行根管治疗并发急性炎症的主要因素,因此,避免急性炎症的发生,术者必须熟悉患牙的解剖形态及其变异,严格按照无菌操作技术预备根管,减少根尖周组织的理化及生理性刺激。

Clinical Observation of Immediate Root Canal Filling for Chronic Periapical Periodontitis

Objective:The aim of this study was to investigate the reason of acute attack and the method for prevention af- ter immediate root canal filling for chronic periapical periodonititis.Methods There were 182 eases between 12 and 75 years old with chronic periapical periodontitis,in which male were 84 and female were 98.All the cases had immediate root canal filling by TRIAUTO-ZX auto root canal filling instument.Results The rate of acute attack was 17.03%,in which femal was 17.34% and male was 16.67% (P>0.05).The rate of 13～35 years old cases was 20.31%,and the rate of 35～55 years was 17.95%,yet,the 55～75 years was 17.64%,(P<0.05).The rate of front teeth was 14.71%,the prmolar teeth was 15. 56% ,and the molar teeth was 17.43% (P>0.05).The rate in the cases which the instrument cut through the periapical hole was 45.51%,the others was 5.63%,(P<0.05).The rate in overfilling cases was 28.57%,and the others was 5.71%,(P<0.05 ).Conclusion The individual factors of patients,the anatomy of teeth and the therapy were the main factors which caused acute after immediate root canal filling for chronic periapical periodontitis.In order to prevent acute attack,dentists must know the anatomy and variation of teeth clearly,prepare root canal sterile and dicrease the physical,chemical and biotic irritations.
