【摘要】 目的:观察新型注射式根管糊剂作为乳牙根管充填材料的疗效。方法:设碘仿氧化锌丁香油糊剂作为对照组,共对224个乳牙行根管治疗观察3个月、1年后的疗效。结果:注射式新型根管糊剂与碘仿氧化锌丁香油糊剂远期疗效有显著差异(t=0.025,P<0.05),尤其在乳磨牙治疗效果更为显著(t=0.02,P<0.05);实验组超充和适充疗效无显著性差异(χ2=0.28,P>0.05),与欠充之间有显著性差异(χ2=6.04,P<0.05)。结论:新型注射式根管糊剂更适合临床作为常规乳牙根管充填材料。更多还原

【Abstract】 Objective: To evaluate the efficacy of novel injectable oxpara paste used as root canal filling material in root canal therapy for primary teeth with periapical periodontitis.Methods: In all 224 teeth,the root canal of 113 teeth were obturated with oxpara paste(test group).The other 111 teeth were obturated with paste iodoform-zinc oxide eygenol (control group).The clinical efficacy was observed after 3 months and 1 year.Results: There’s significant difference between two groups in prospective efficacy(t=0.025,P<0.05),especially for primary molars(t=0.02,P<0.05).In test group,there’s no significant deviation between exceed and appropriate obturation(χ~2=0.28,P>0.05),but significant deviation among the exceed,appropriate obturation teeth and insufficient obturation teeth(χ2=6.04,P<0.05).Conclusion: The novel injectable oxpara paste is more suitable for treatment of periapical periodontitis of primary teeth.更多还原
