摘　　要：目的观察在乳磨牙深龋治疗中,矿物三氧化物凝聚体(MTA)与戊二醛用于活髓切断术的临床疗效。方法选择80例乳磨牙深龋患儿,随机分成2组,治疗组活髓切断术后用MTA盖髓,对照组活髓切断术后用戊二醛盖髓,术后跟踪随访6个月,1年和2年的临床疗效。结果 2组6个月时成功率相近,但1年后及2年后MTA组成功率高于戊二醛组,差异有统计学意义(P<0.05)。结论 MTA用于乳磨牙活髓切断术远期临床疗效优于戊二醛。Objective To observe the effectiveness of vital pulpotomy with mineral trioxide aggregate（MTA） and glutaraldehyde during the treatment of primary teeth.Methods 80 deciduous molars with deep caries from 4-8 year-old children were selected.All selected teeth were randomly divided into control group（using glutaraldehyde pulpotomy） and experimental group（using MTA pulpotomy）.Patients were recalled for clinical and radiographic evaluation in 6-month,one-year and two-years periods.Results 6 months after the treatment,the rates of success in both groups were close,but after one year and two years,the rate of success in experimental group was higher than that in control group.There was statistically significant difference in the success rate of teeth treated with MTA pulpotomy in comparison to those treated with glutaraldehyde pulpotomy﹙P0.05﹚.Conclusions The clinical effectiveness of vital pulpotomy in primary teeth with MTA is better than that with glutaraldehyde.
