氢氧化钙-地塞米松糊剂预防根管治疗期间急症的临床研究

Prevention of Root Canal Therapy Emergencies by Biocalc-dexamethasone Paste

目的:评价采用氢氧化钙-地塞米松糊剂根管封药预防根管治疗期间急症的临床效果。方法:200例慢性根尖周炎、牙髓坏死、残根、残冠,需行根管治疗的患者,随机分为两组,实验组用氢氧化钙-地塞米松糊剂封药,对照组用FC封药,每组100例。结果:实验组急症发生率(4%),显著低于对照组(28%)。结论:氢氧化钙-地塞米松糊剂能有效预防根管治疗期间急症的发生和降低约诊间疼痛程度。

Objective： To appraise the effect of adopting biocalc--dexamethasone paste to seal off the root canal on preventing from endodontic interappomtment emergencies. Methods： 200 cases of chronic periapical periodontitis, pulp necrosis, remaining root and remaining crowns that needed to treat the root canal were divided in two groups randomly. One group used biocalc--dexamethasone pasteas as seal off medicine, the control group used FC. Each group had 100 samples. Results： Acute disease incidence in experimental groups was 4%, obviously lower than 28% in control group. Conclusion： Biocalc--dexamethasene paste can effectively prevent endodontic interappomtment emergencies.
