三氧化矿物凝聚体修补根管侧穿、髓底穿孔的临床效果

摘要

ObjectiveTo study the clinical effect of mineral trioxide aggregate (MTA) in repairing the root canal perforation and perforation of pulp lfoor.Method168 patients with the root canal perforation and perforation of pulp lfoor treated in our hospital from September 2012 to March 2013 were selected as objects of study and they were randomly divided into research group and control group, 84 cases in each group. Patients in research group were given MTA to repair the perforation, patients in control group were given the light-curing calcium hydroxide to repair the perforation. During 1-year follow-up, the clinical effects of the two groups were compared.ResultThe total effective rate of research group was 90.48% (76/84), signiifcantly higher than control group [71.43% (60/84)] (P<0.05). The total effective rate was 100.00% (48/48) in the treatment of patients with perforation diameter less than 2 mm, which was signiifcantly higher than that of the perforation diameter of 2 mm patients with [77.78% (28/36)] (P<0.05). The overall response rate of patients with the iatrogenic perforation was 100.00% (47/47), which was significantly higher than patients with the carious perforation [78.38% (29/37)] (P<0.05).ConclusionThe clinical effect of MTA in the treatment of root canal perforation and perforation of pulp lfoor is outstanding and it has the extremely high clinical value especially in the treatment of teeth with the diameter of perforation less than 2 mm and with the iatrogenic perforation.%目的：观察三氧化矿物凝聚体（mineral trioxide aggregate，MTA）修补根管侧穿、髓底穿孔的临床效果。方法选取2012年9月至2013年3月本院收治的168例根管侧穿、髓底穿孔患者为研究对象，随机分为研究组和对照组，每组各84例。研究组患者应用MTA实施穿孔修补术，对照组患者应用光固化氢氧化钙实施穿孔修补术。随访1年，比较两组患者的临床疗效。结果研究组患者治疗总有效率为90.48%（76/84），显著高于对照组[71.43%（60/84）]（P＜0.05）。穿孔直径＜2 mm患者治疗总有效率为100.00%（48/48），显著高于穿孔直径≥2 mm患者[77.78%（28/36）]（P＜0.05）。医源性穿孔患者治疗总有效率为100.00%（47/47），显著高于龋源性穿孔患者[78.38%（29/37）]（P＜0.05）。结论 MTA修补根管侧穿、髓底穿孔临床疗效确切，尤其在穿孔直径＜2 mm的患牙及医源性穿孔的患牙治疗方面具有极显著的临床价值。
