地塞米松-氢氧化钙糊剂用于根管治疗术一次法缓解疼痛的疗效评价

Clinical observation of calcium hydroxide-dexamethesone paste in one-visit root canal therapy

目的观察地塞米松-氢氧化钙糊剂应用于根管治疗术一次法缓解疼痛的短期临床疗效。方法将63颗患牙随机分为两组行根管治疗术一次法,实验组用地塞米松-氢氧化钙糊剂,对照组用AHPlus糊剂,观察根充后缓解疼痛的临床疗效。结果实验组根管治疗期间疼痛的发生率为3.1%,对照组为9.7%,两组间差异有显著性(P<0.01)。有瘘型两组间差异无显著性(P>0.05),而无瘘型实验组根管治疗期间疼痛发生率为8.3%,对照组为18.2%,两组间差异有显著性(P<0.01)。结论地塞米松-氢氧化钙糊剂应用于根管治疗术一次法能有效降低根管治疗期间疼痛的发生。

[Objective] To observe the short-time clinical effect of calcium hydroxide-dexamethesone paste in one-visit root canal therapy. [Methods] 63 diseased teeth were randomly divided into two groups and treated by one-visit root canal therapy. Calcium hydroxide-dexamethesone paste was used in experimental group and AH Plus paste was used in control group. The clinical efficacy after 1-week period was observed. [Results] The incidence of endodontic interappointment pain （EIP） in experimental group was significantly lower than that in control group （P 〈 0.01）. The EIP incidence was no significant difference between two groups of chronic fistulous periapical periodontitis. The EIP incidence in experimental group of chronic periapical periodontitis without fistula was significantly lower than that in control group （P 〈 0.01）. [Conclusion] The investigation proves that calcium hydroxide-dexamethesone paste can effectively decrease the EIP incidence in one-visit root canal therapy.
