【摘要】 目的:比较氢氧化钙碘仿(CHI)糊剂与传统的根管消毒剂甲醛甲酚(FC)、樟脑酚(CP)的临床效果。方法:选择需作根管治疗的患者142例,患牙165颗,随机分为CHI、FC、CP组,常规镍钛根管预备后分别封入上述药物于根管及髓腔中,观察比较根管预备封药后发生根管治疗期间疼痛(EIP)的情况、临床疗效及完成根管治疗的复诊次数。结果:CHI组EIP的发生率最低、临床有效率最高、复诊次数最少,与FC组有显著性差异(P<0.05),但与CP组的差异无显著性(P>0.05)。讨论:与传统的酚类根管消毒药物(FC、CP)相比较,CHI封药不易导致EIP,临床疗效高、疗程短、操作简便、无细胞毒性及抗原性,是一种较理想的根管消毒剂。更多还原

【Abstract】 Objective:To compare the clinical effects of calcium hydroxide iodoform(CHI)slurry and traditional intracanal medication such as formocresol(FC),camphophenic(CP).Methods:165 permanent teeth needed root canal therapy collected from 140 patients were divided randomly into 3 groups.After mechanical preparation of the root canals using the crown-down technique,three intracanal medications(CHI,FC and CP)were used respectively.The endodontic interappointment pain(EIP),clinical effects and treatment times to finish root canal treatment were observed and compared.Results:Compared with other two groups,the CHI group had a lower EIP rate,better therapeutic effect and shorter treatment time.There was significant difference between the CHI group and the FC group(P<0.05);however,there was no significant difference between the CHI group and the CP group(P>0.05).Conclusion:Compared with traditional intracanal medications(FC,CP),CHI slurry rarely causes EIP.Its clinical effects are excellent and treatment time is short.It is an ideal intracanal medication.更多还原
