Abstract

In 29 teeth, apicoectomies with retrograde instrumentation and retrofilling with low temperature thermoplasticized gutta-percha were performed. Nineteen of them were clinically an radiographically evaluated, showing the following average rate: successes 84.2% (16 cases), failures 10.5% (2 cases) and incomplete healing 5.2% (1 case). The observation period varied from 12 to 41 months. The use of retrograde instrumentation an retrofilling with thermoplasticized gutta-percha is suggested as a useful method in surgical procedures.

摘要

对29颗牙齿进行了根尖切除术，采用逆行根管预备并使用低温热塑牙胶进行根管倒充填。其中19颗牙齿进行了临床和影像学评估，结果显示以下平均比率：成功84.2%（16例），失败10.5%（2例），愈合不完全5.2%（1例）。观察期为12至41个月。建议采用逆行根管预备并使用热塑牙胶进行根管倒充填，作为外科手术中的一种有效方法。
