Impacts of the Triple bristles three-sided sonic powered toothbrush on tooth shade, plaque control and gingival health.

Abstract

To evaluate the efficacy of the Triple bristles three-sided sonic powered toothbrush in plaque removal and its impact on tooth shade and gingival health, and to compare this with a conventional manual toothbrush. Fifty two participants (26males and 26 females; mean age [SD]=22.48 [1.52], SE=0.210, 95% CI=22.06-22.90) were recruited into this controlled within-subject, randomized, two-treatment, 1-month crossover and examiner-blinded observational study between October 2020 and January 2021 in the School of Dentistry, University of Jordan. Within each participant, the upper and lower jaws were randomized to receive a brushing protocol either with the Triple bristles three-sided sonic brush or with a soft manual standard toothbrush with flat trimmed bristles. Tooth shades were recorded for upper and lower anterior and premolar teeth. The Turesky-Modified Quigley-Hein Plaque Index (TMQHPI) and bleeding on probing (BOP) were evaluated at study baseline, 1week and 1month after applying the brushing protocol. Both tested brushes were associated with significant reduction in plaque scores and BOP (p<0.05). The Triple bristles brush was more effective in reduction in plaque and BOP in the lower jaw and among females than the manual brush (p<0.05). The Triple bristles brush was more superior for reduction in plaque and probing on bleeding in the lower jaw and among females.
