Abstract
OBJECTIVE
The purpose of this randomized controlled study is to determine if an interactive power toothbrush (PTB) with application (app) promotes additional benefit on dental plaque, gingivitis, and gingival abrasion to that of a manual toothbrush (MTB).
MATERIALS AND METHODS
Ninety participants (dental students) diagnosed with gingivitis were randomly assigned, into three groups, 1:1:1 ratio, given an app-assisted interactive PTB (PTB-A) (Oral-B Genius® Rechargeable 8000 PTB with CrossAction brush head) or the same PTB without app-assistance (PTB-NA) or a regular MTB for home-use. Plaque was assessed using the Turesky modification of the Quigley and Hein Plaque Index (QHPI-TM), and gingivitis was evaluated using the Bleeding on Marginal Probing Index (BOMP) at baseline (T0), week 2 (T1), and week 8 (T2). Gingival abrasions were recorded at T1 and T2. Exit survey was used to assess brushing time and visual-analogue-scale (VAS) scores.
RESULTS
PTB improved QHPI-TM significantly in terms of time-dependent changes, irrespective of app-assistance. BOMP was observed to be statistically lower in PTB-A than in MTB only at T2. Brushing times were longer in PTB-A than in MTB. Gingival abrasion was less in both PTB than MTB. PTB-A had better results to MTB in cleaning ability according to subject-reported outcomes.
CONCLUSIONS
Both PTBs were more effective to MTB; however, the app-assisted interactive PTB was similar to the non-assisted one in plaque removal efficacy, gingivitis reduction, and incidence of gingival abrasion, yet better than MTB in cleaning ability.
CLINICAL RELEVANCE
Developing an application software to prevent gingival abrasion might be clinically beneficial regardless of the individual factor.
