摘　　要：目的通过比较无机三氧化聚合物(MTA)与氢氧化钙加碘仿成品糊剂(Vitapex)促年轻恒牙根尖闭合的疗效和二者治疗成本-效益比,寻求更优方案。方法选择牙根长度发育达2/3、根管下段管壁呈平行或内聚型的70颗全部牙髓感染或伴发根尖周炎的年轻恒牙,分别采用MTA与Vitapex促根尖闭合并进行卫生经济学分析。结果经2年追踪观察,术后患牙100%临床不适症状消失。MTA和Vitapex促根尖闭合成功率分别为100%和92.6%,差异无统计学意义。就诊次数和治疗周期分别为2.3次7、.8 d和7.0次2、67.9 d,差异均有统计学意义(P<0.01);人均最小成本分别为797.1元和1 043.3元,成本-效益比分别为7.97和11.27,差异均有统计学意义(P<0.01)。结论在已发生全部牙髓感染或伴发根尖周炎的年轻恒牙根尖闭合治疗中,MTA即刻封闭和Vitapex长期根尖诱导的方案均有效,以前者更优。Objective To finding the superior scheme though comparing efficacy and cost-benefit ratio between Mineral Trioxide Aggregate（MTA）and Vitapex in the treatment of apical closure of young permanent teeth.Methods Seventy pulpal or periapical tissue infected young permanent teeth,which developed root length exceed 2/3 and apical walls were convergent or parallel,were treated with MTA and Vitapex.The health economics analysis was performed.Results After two years follow-up observation,the success rate of clinical symptoms was 100%.In terms of apical closure,the success rates for MTA and Vitapex group were 100% and 92.6%,with no significant difference（P0.05）.Average visiting number and treatment period of MTA were 2.3 times and 7.8 days;Average number and period of Vitapex were 7.0 times and 267.9 days,which was significantly longer than MTA（both P0.01）.For MTA and Vitapex group,the health economics analysis showed that average minimization cost of each case were 797.1 Yuan and 1043.3 Yuan respectively and cost-benefit ratio were 7.91 and 11.27 respectively,with significant difference（both P0.01）.Conclusion Both MTA immediate sealing and Vitapex long-term apexification are effective in the treatment of apical closure of pulpal or periapical tissue infected young permanent teeth,but the former is superior with lower cost-benefit ratio.
