Abstract
The aim of this randomized-controlled, single-blinded study was to compare the effects of mechanical tooth cleaning (MTC) and ultrasonic debridement (UD) on oral hygiene status in healthy young adults. Thirty-seven participants (mean age: 20.3±0.62 years) were divided into 3 groups after pre-examination: group A, receiving MTC; B, receiving MTC+UD using a universal insert (UDUI); and C, receiving MTC+UD using a probe-shaped insert (UDPI). All participants were required to abstain from oral hygiene for 24 hours after the allocated intervention, after which they were examined. A masked examiner determined the Quigley-Hein plaque index (PlI) and Silness and Löe gingival index (GI) scores before the interventions and after 24 hours of non-brushing. A significant increase in the PlI score was observed in group A (p<0.001) in comparison with that in group B (A: 0.311±0.26; B: -0.01±0.33; C: 0.13±0.27; p<0.05). A significant decrease in the GI score was observed in groups B and C (p<0.05), and the change in this score in group C significantly differed from that in group A or B (A: -0.04±0.25; B: -0.13±0.17; C: -0.33±0.2; p<0.05). Only MTC was insufficient to prevent plaque formation over a 24-hour period of non-brushing and decrease the GI score. Ultras...
