氢氧化钙碘仿甘油糊剂用于根管消毒的临床研究

目的:观察氢氧化钙碘仿甘油糊剂用于根管消毒的临床疗效。方法:选择需做根管治疗的门诊患者145例,患牙145颗,随机分为氢氧化钙碘仿甘油糊剂(A组)、樟脑苯酚(B组)、甲醛甲酚(C组)3组,常规根管预备后分别封入上述药物于根管及髓室内,比较3组发生急性反应(EIP)情况和临床疗效。结果:A组EIP发生率(8.16%)最低、有效率(97.96%)最高,与B组的31.91%、68.09%,C组的34.69%、71.43%比较有显著性差异(P<0.05)。结论:氢氧化钙碘仿甘油糊剂用于根管消毒的临床疗效较好,优于传统药樟脑苯酚和甲醛甲酚,是一种较理想的根管消毒剂。

Clinic Efficacy of Calcium Hydroxide Iodoform Glycerin Paste for Root Canal Disinfection

OBJECTIVE： To evaluate the clinical efficacy of Calcium Hydroxide Iodoform Glycerin （CHIG） paste for root canal disinfection. METHODS： 145 patients （145 teeth） requiring root canal therapy were divided randomly into CHIG group, formo - cresol solution group （Group B） and camphor phenol group （Group C）. After root canal preparation, the corresponding drugs were introduced into root canal and pulp chamber. The endodontic interappointment pain （EIP） and clinical efficacy in the 3 groups were Compared. RESULTS： In Group A, the EIP incidence was the lowest （8.16%） while the effective rate was the highest （97.96%）, showing significant differences as compared with Group B（31.91% and 68.09%, respectively） or Group C （34.69% and 71.43 %, respectively） （P 〈 0.05） . CONCLUSION： Calcium Hydroxide Iodoform Glycerin Paste is an effective ideal agent for root canal disinfection with better clinical efficacy than that of the traditional camphor phenol or formocresol solution.
