The use of biocompatible materials like mineral trioxide aggregate (MTA) may improve the prognosis of teeth with root perforations.
The treatment outcome of root perforations repaired between 2000 and 2006 with MTA was investigated. Twenty-six patients received treatment with MTA in 26 teeth with root perforations. Treatment was performed by supervised undergraduate students (29%), general dentists (52%), or dentists who had focused on endodontics (19%). Perforation repair by all treatment providers was performed using a dental operating microscope. Calibrated examiners assessed clinical and radiographic outcome 12 to 65 months after treatment (median 33 months, 81% recall rate). Pre-, intra-, and postoperative information relating to potential prognostic factors was evaluated.
Of 21 teeth examined, 18 teeth (86%) were classified as healed. None of the analyzed potential prognostic factors had a significant effect on the outcome.
MTA appears to provide a biocompatible and long-term effective seal for root perforations in all parts of the root.
使用生物相容性材料（如矿化三氧化物凝聚体，MTA）可能会改善有牙根穿孔的牙齿的预后。
研究了 2000 年至 2006 年间使用 MTA 修复的牙根穿孔的治疗效果。26 名患者的 26 颗牙根穿孔牙接受了 MTA 治疗。治疗由监督本科生（29%）、普通牙医（52%）或专注于牙髓病学的牙医（19%）进行。所有治疗提供者均使用牙科手术显微镜进行穿孔修复。校准检查者在治疗后 12 至 65 个月（中位数 33 个月，81%的召回率）评估临床和放射学结果。评估了与潜在预后因素相关的术前、术中和术后信息。
在 21 颗受检牙齿中，18 颗牙齿（86%）被归类为愈合。分析的潜在预后因素均未对结果产生显著影响。
MTA 似乎为牙根的所有部位的牙根穿孔提供了一种生物相容性和长期有效的密封。
