这项初步研究的目的是评价三氧化矿物聚合体(MTA)作为根尖诱导材料用于儿童非生命未成熟恒切牙的临床疗效。15名平均年龄为11.7岁的儿童和17颗无生命恒切牙被判定为适合纳入。遵循标准的根管治疗程序，在使用氢氧化钙根管内敷料至少1周后，使用MTA制作3~4 mm的根尖塞。在MTA放置后至少1周，用热塑性牙胶(Obtura II)完成最后的充填。每隔3个月对受试者进行临床和放射学检查。MTA的平均随访时间为12.53个月(+/-2.94 SD)。在总共治疗的17颗牙齿中，13颗牙齿的MTA放置被认为是适当的。临床成功率为94.1%，放射学成功率为76.5%，另有3例(17.6%)结果不确定。这是为数不多的报道MTA作为根尖诱导材料应用于无活力牙齿和牙根发育不全的儿童的研究之一。然而，需要更大规模的临床研究来评估这一手术的长期成功。
The aim of this pilot study was to evaluate the clinical efficacy of mineral trioxide aggregate (MTA) as an apexification material when used in non-vital immature permanent incisors in children. Fifteen children with a mean age of 11.7 years and 17 non-vital permanent incisors were ajudged suitable for inclusion. Standard endodontic procedures were followed and an apical plug of 3-4 mm was created by using MTA after a calcium hydroxide intracanal dressing had been applied for at least 1 week. Final obturation was completed by using thermoplastisized Gutta-Percha (Obtura II) at least 1 week following MTA placement. Subjects were reviewed clinically and radiographically at 3-month intervals. Mean follow-up time for MTA was 12.53 months (+/- 2.94 SD). Of the total of 17 teeth treated, MTA placement was considered to be adequate in 13 teeth. The procedure showed clinical success in 94.1% of the cases, radiographic success was found to be 76.5% and in further three cases (17.6%) the outcome was considered to be uncertain. This is one of the very few studies that have reported the out coming of MTA as an apexification material in children with non-vital teeth and incomplete root development. However, larger clinical studies are required to evaluate the long-term success of this procedure.
