The use of ultrasonic instrumentation in the cleansing and enlargement of the root canal.
The purpose of this study is to compare the cleansing effect of ultrasonic devices with that of hand instrumentation. When ultrasonic instrumentation is used in a curved canal, instruments should be precurved to some degree. The ultrasonic method is superior to the manual method in removal of debris from the root canal.
