Abstract

Introduction: Surgical endodontics try for healing conventional root canal treatment failed, improving previous sealing through filling of a root-end cavity. Actual/y is not clear if it is better used stainless steel ultrasonic retrotips than diamond-coated ultrasonic retrotips far cavity preparation. Moreover, surgical endodontics published results are discussable. The aim of present study is two-fold: first, to show the success rote of surgical endodontics based in ultrasonics; and second, to evaluate both retrotips (stainless steel and diamond-coated) influence in success rote. Materials and methods: lt was designed a 1-year and 2-years follow-up clinical and prospective study and developed a modern surgical endodontics based in ultrasonics and root-end filling with MTA (Mineral Trioxide Aggregate). Follow-up examination included clínical and radiographic assessment. Results: lt was included 161 teeth from 101 patients. 1-year follow-up showed 117 teeth examined with 79,4% general success rate, 75,3% stainless steel success rate and 85,3% diamond-coated success rate. 2-years follow-up showed 118 teeth examined with 82,2% general success rate, 79,3% stainless steel success rate and 87,9% diamond-coated success rate. Statistical analysis showed no significant difference in success between retrotips. Conclusions. Surgical endodontics based in ultrasonic showed high success rates with two types of retrotips and there are no statistical differences between stainless steel retrotips and diamond-coated retrotips, although diamond-coated retrotips showed better results.
