选择性去髓术中约诊间痛发生的研究

目的:探讨选择性去髓术中的约诊间痛发生率和影响因素。方法:对门诊中选择性去髓术的218个活髓牙(117例患者)进行根管预备后疼痛程度的临床调查;分析不同医师、根管预备方法等治疗因素对疼痛的影响。结果:选择性去髓术的根管预备后疼痛发生率为28.4%。约诊间痛发生率为0.46%。不同医师、不同根管预备方法对活髓牙根管预备后疼痛发生均无明显影响(P>0.05)。而牙根情况影响根管预备后疼痛发生(P<0.01)。结论:创伤因素可以引起约诊间痛,严格遵守操作规程是减少创伤、降低疼痛发生的关键。

Study of flare- up during selected pulpectomy

AIM:To examine the incidence and factors affecting flare-ups during selected pulpectomy.METHODS:218 teeth(117 patients) with vital pulp were randomly assigned to four groups for pulpectomy.The incidence and degree of post-operative pain after root canal preparation between different dentist and different preparatory techniques were recorded.RESULTS:The incidence of post-operative pain was 28.4%,while the incidence of flare-ups was 0.46%.The difference among dentists and preparatory techniques were no statistically significance((P>0.05)).The incidence of post-operative pain of multi-roots tooth was more than that of single-root tooth((P<0.01)).CONCLUSION:Trauma may cause flare-ups.pulpectomy should be done strictly.
