Flat root surface areas of formalin‐stored mandibular incisors with plaque and calculus were scaled by sonic (PHATELUS® SONIC SCALER, SONIC FLEX 2000®, TITAN‐S® SONIC SCALER) or ultrasonic instruments (HY‐GIENIST® ULTRASONIC SCALER, CAVITRON®) or by a new reciprocating scaling insert for the EVA/PROFIN® system. The test areas were photographed by SEM and coded micrographs were independently graded by three examiners using the RCI (Remaining Calculus Index) and the RLTSI (Roughness Loss of Tooth Substance Index). The findings revealed that the sonic sealers as a group removed calculus more completely but also left significantly more roughness and loss of tooth substance than the other instruments tested. No difference was seen between the two ultrasonic sealers. The reciprocating insert gave results similar to those of the ultrasonic except for the scaling time which was significantly longer for the new “cleansing principle”.
