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

Objectives: To evaluate the efficacy of the Triple bristles three-sided sonic poweredtoothbrush in plaque removal and its impact on tooth shade and gingival health, andto compare this with a conventional manual toothbrush.Methods: Fifty two participants (26 males 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 obser-vational study between October 2020 and January 2021 in the School of Dentistry,University of Jordan. Within each participant, the upper and lower jaws were rand-omized to receive a brushing protocol either with the Triple bristles three-sided sonicbrush or with a soft manual standard toothbrush with flat trimmed bristles. Toothshades were recorded for upper and lower anterior and premolar teeth. The Turesky-Modified Quigley-Hein Plaque Index (TMQHPI) and bleeding on probing (BOP) wereevaluated at study baseline, 1 week and 1 month after applying the brushing protocol.Results: Both tested brushes were associated with significant reduction in plaquescores and BOP (p < 0.05). The Triple bristles brush was more effective in reduction inplaque and BOP in the lower jaw and among females than the manual brush (p < 0.05).Conclusions: The Triple bristles brush was more superior for reduction in plaque andprobing on bleeding in the lower jaw and among females
