Abstract

BACKGROUND/AIM: The placement of a biocompatible material after performing pulp therapy in traumatically exposed permanent incisors is one of the important factors that determine pulp healing. The aim of this study was to assess the clinical and radiographic outcomes when using mineral trioxide aggregate (MTA) and Biodentine as pulpotomy materials to maintain the vitality of traumatized immature anterior permanent teeth with pulp exposure.

MATERIALS AND METHODS

Fifty traumatized immature anterior permanent teeth with exposed pulps were included in the study. Teeth were equally divided and randomly assigned to two groups MTA or Biodentine. After pulpotomy, pulp stumps were covered with MTA or Biodentine followed by a permanent restoration. Blinded clinical and radiographic evaluations were performed at baseline, immediate post-operative and after 6, 12 and 18 months according to pre-determined clinical and radiographic criteria.

RESULTS

No statistically significant differences were observed between MTA and Biodentine for any of the clinical parameters, except for discoloration, which was significantly more prevalent in the MTA group (P < .001). No significant statistical difference was observed in the radiographic outcomes between MTA and Biodentine, as evidenced by continued root development and by an increased prevalence of root formation stage H in both groups.

CONCLUSIONS

Both MTA and Biodentine showed similar clinical and radiographic outcomes when used as pulpotomy materials in the treatment of traumatized immature anterior permanent teeth. However, discoloration was significantly more prevalent in the MTA group.

摘要

背景/目的:在创伤性暴露的恒牙进行牙髓治疗后放置生物相容性材料是决定牙髓愈合的重要因素之一。本研究的目的是评估使用三氧化矿物凝聚体(MTA)和生物活性玻璃陶瓷作为牙髓切断术材料来维持外伤后未成熟恒前牙牙髓暴露活力时的临床和影像学结果。

材料与方法

本研究纳入50颗外伤后未成熟恒前牙且牙髓暴露。牙齿平均分为两组,随机分配至MTA组或生物活性玻璃陶瓷组。牙髓切断术后,牙髓残端用MTA或生物活性玻璃陶瓷覆盖,随后进行永久修复。根据预先确定的临床和影像学标准,在基线、术后即刻以及6、12和18个月后进行盲法临床和影像学评估。

结果

除变色外,MTA组和生物活性玻璃陶瓷组在任何临床参数上均未观察到统计学显著差异,MTA组变色更为普遍(P <.001)。MTA组和生物活性玻璃陶瓷组在影像学结果上未观察到显著统计学差异,两组均表现为牙根持续发育且牙根形成阶段H的发生率增加。

结论

在治疗外伤后未成熟恒前牙时,MTA和生物活性玻璃陶瓷作为牙髓切断术材料显示出相似的临床和影像学结果。然而,MTA组变色更为普遍。
