Clinical evaluation of subgingival debridement with ultrasonic instruments used by trained and untrained operators

Previous studies have proven the efficacy of modified ultrasonic (EWP-12 R & L) inserts in scaling and root planing (root debridement) procedures performed by skilled periodontists and dental hygienists. This study was undertaken to compare and skilled operators in these tasks. Using a slightly altered testing protocol, untrained operators demonstrated equal ability. A reevaluation of current thinking in the training of professionals in scaling and root planning (root debridement) procedures is suggested. Future studies are needed to determine if a training protocol is possible to prepare inexperienced operators to use ultrasonic instruments for subgingival scaling and root planing.
