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.

Conditions

Interventions

DEVICE

Reference MTB

Participants will brush their teeth with manual toothbrush and 1.3 g ± 0.1 g of fluoride toothpaste (containing 0.76% w/w sodium monofluorophosphate) for 1-timed minute under supervision of study staff.

DEVICE

Reference PTB

Participants will brush their teeth with power toothbrush and 1.3 g ± 0.1 g of fluoride toothpaste (containing 0.76% w/w sodium monofluorophosphate) for 2-timed minute under supervision of study staff.

DEVICE

Prototype PTB (Gum line mode)

Participants will brush their teeth with prototype PTB toothbrush and 1.3 g ± 0.1 g of fluoride toothpaste (containing 0.76% w/w sodium monofluorophosphate) for 2-timed minute in "Gum Line" mode under supervision of study staff.

DEVICE

Prototype PTB (Combined mode)

Participants will brush their teeth with prototype PTB toothbrush and 1.3 g ± 0.1 g of fluoride toothpaste (containing 0.76% w/w sodium monofluorophosphate) for 2-timed minute in "Gum Line" mode and 1-timed minute in "Interdental" mode under supervision of study staff.
