Endodontics in primary molars using ultrasonic instrumentation.

Abstract

PURPOSE: The purpose of this study, which is a series of consecutive case reports, was to describe and evaluate the protocol used in the treatment of pulpal necrosed of primary molars, used by the dental service of Social Support Foundation of the Moinhos de Vento Hospital, Porto Alegre, RS, Brazil. METHODS: Eighteen primary molars in 15 children, ranging from 4 to 10 years of age, were endodontically treated using ultrasonic instrumentation. RESULTS: Clinical and radiographic controls showed a success rate of 94%, considering an evaluation time of 14.1+/-6.3 months. CONCLUSIONS: The use of ultrasonic instrumentation in primary molars with pulpal necrosis succeeded in reducing appointment time and showed a high success rate.
