Randomized Controlled TrialEffect of eutectic mixture of local anesthetics on pain perception during scaling by ultrasonic or hand instruments: a masked randomized controlled trial.
The aims of this study are to evaluate the efficacy of a eutectic mixture of local anesthetic (EMLA) cream on pain perception during scaling and to compare the intensities of pain provoked by hand and ultrasonic instruments. ⋯ Although most patients experienced limited pain during scaling, a significant reduction of pain is achieved by using EMLA cream and ultrasonic scaler.
