The purpose of this study was to evaluate the outcome of apexogenesis with mineral trioxide aggregate (MTA) in traumatised anterior and carious posterior teeth over 5 years. A comprehensive chart review was performed to obtain a retrospective of sequential previously completed cases with recalls. Clinical and radiographic data were collected for 97 vital immature teeth (40 traumatised anterior and 57 carious posterior teeth) pulpotomised (partial or full pulpotomy) using MTA with an average follow-up time of 5 years. Chi-squared test and Fisher's exact test were implemented to analyse data. The success rate in anterior teeth and posterior teeth was 82.5% and 96.4% respectively. Crown discolouration was observed in 25 (62.5%) anterior teeth. There was a significant difference between the number of successful and unsuccessful cases (P < 0.05) and there was no correlation between type of treatment and success/failure (P > 0.05). The success rate of apexogenesis using MTA in immature teeth was relatively high.
本研究的目的是评估使用三氧化矿物凝聚体（MTA）对受创伤的前牙和龋坏的后牙进行根尖诱导成形术5年的治疗效果。进行了全面的病历回顾，以回顾性分析一系列先前完成并进行了随访的病例。收集了97颗活力未成熟牙齿（40颗受创伤的前牙和57颗龋坏的后牙）的临床和影像学数据，这些牙齿采用MTA进行了牙髓切断术（部分或完全牙髓切断术），平均随访时间为5年。采用卡方检验和Fisher精确检验对数据进行分析。前牙和后牙的成功率分别为82.5%和96.4%。25颗（62.5%）前牙出现了冠变色。成功和失败病例数之间存在显著差异（P<0.05），治疗类型与成功/失败之间无相关性（P>0.05）。使用MTA对未成熟牙齿进行根尖诱导成形术的成功率相对较高。
