Summary:

      The aim of this study is to evaluate the ability of a prototype power toothbrush (PTB) versus
      a manual toothbrush in healthy, right-handed manual toothbrush (MTB) participants with no
      signs of periodontal disease or excessive recession to remove dental plaque after a single
      tooth brushing event. Prior to each treatment visit, participants will abstain from oral
      hygiene for a period of 12 hours preceding a pre-brushing dental plaque evaluation.
      Participants will then brush once under supervision for 2 minutes in 'Gum line' mode and
      1-minute in 'Interdental' mode after which re-disclosing and a post-brushing plaque
      assessment will be carried out.
