The ultrasonic NO PAIN technology (Electro Medical Systems, Nyon, CH) promises minimal pain during debridement due to linear oscillating action combined with a sinusoidal power output and feedback control. The aim of the present study was to measure pain perception on a visual analogue scale (VAS) during supportive periodontal therapy including debridement of hypersensitive teeth. Two ultrasonic scalers were used, one with and one without NO PAIN technology. In a randomized-controlled clinical study with split-mouth design, 100 hypersensitive teeth matched for air blast hypersensitivity were either treated with the ultrasonic device Piezon Master 700 or the Mini Piezon (both EMS, Nyon, CH). Pain perception during debridement was assessed by a VAS (range 0-10). The average VAS for the test device Piezon Master 700 with NO PAIN technology was 3.16 ± 2.10, and for the control device Mini Piezon without NO PAIN technology 3.40 ± 2.59 (p = 0.490). Placing an arbitrary threshold at the VAS score of 3 for significant pain experience, 60 % of the subjects experienced no significant pain with either instrument. No statistically significant difference in perceived pain between the instruments used was found. Both ultrasonic devices showed very small pain intensities during debridement of highly hypersensitive teeth and can therefore be recommended for supportive periodontal therapy.
