The variation in the effects of scaling devices on calculus removal, root surface roughness was unknown. This study evaluated the effectiveness of three piezoelectric ultrasonic scalers and a hand scaler in removing calculus. Twenty four extracted permanent teeth coated with artificial calculus were randomly assigned into four groups of scaler types: (1) EMS scaler (2) Gracey curette #5/6 (3) Satelec scaler (4) Kavo scaler for root planing. After instrumentation, the root surface were assessed for roughness and remaining calculus using a digital microscope Hirox KH-7700 version 2.0 (Hirox, Japan) under x50 magnification. The length of procedural time was also recorded. The remaining calculus was significantly lower for the EMS scaler group (0.32 mm2) than for the Kavo group (1.01 mm2), P= 0.037. The mean scores of surface roughness for the Gracey scaler group (15.90 mm2) was statistically significantly more than for the Satelec scaler group (5.38 mm2),P= 0.047. The mean time spent to remove calculus for the Gracey scaler group was significantly longer (16.76 min) than for the EMS (11.36 min; P=0.031) and Kavo scaler groups (11.41 min; P=0.033). The results indicate EMS scaler group is more favourable than the other piezoelectric scaler groups and Gracey scaler.
