The aim of this study is to describe the protocol used in the treatment of pulpally necrosed primary molars and to evaluate the effectiveness of ultrasonic instrumentation technique in primary dentition.

Materials and methods

A total of 50 primary molars in 40 children, ranging from 8 to 10 years of age, were endodontically treated using standard protocols and ultrasonic instrumentation. The follow-up was done for each case ranging from 1 to 2½ years.


Clinical and radiographic controls showed a success rate of 97.5%, considering an evaluation time of 19 ± 9.02 months.


The use of ultrasonic instrumentation in primary molars with pulpal necrosis succeeded in reducing appointment time and showed a high success rate.

Clinical significance

Ultrasonic instrumentation should be used as a standard protocol in instrumentation of endodontic treatment of primary molars so as to increase the success rate of primary teeth pulpectomies.
