[Use of thermoplasticized gutta-percha in retrograde obturation]

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.
