[Microscopic analysis of the effects of ultrasonic instrumentation on the root surface of molar furcations].
Twenty molars, 10 from the maxilla and 10 from the mandible with furcation areas type II (Staffileno) were instrumented in their inter-radicular area with P10 instrument of Cavitron. It was established that the furcations of easier access instrumentation were the lingual o lower teeth and the buccal of the upper, and the most difficult accessibility were the distal of upper molars. The instrumentation can leave grooves or deformations, depending on the instrument to the area. It was concluded that ultrasonic instrument are useful removing supragingival calculus and bacterial plaque, and it must be limited to perform such procedures.
