Gutta percha removal utilizing GPX instrumentation.
Two studies were performed in order to test the efficiency of GPX rotary instrumentation in removing gutta percha from endodontically-treated extracted teeth. A pilot project compared GPX to gates glidden instrumentation, and then a GPX technique was performed on 60 obturated mesial canals of mandibular molars. Assessment of the technique included radiographic and microscopic analysis of remaining debris. Results indicated that the GPX is a useful adjunct in these retreatment procedures. The clinical technique and time involved in the use of the GPX are discussed.
