Intervention / Treatment
Detailed Description
This will be a single center, 4-week, randomized, controlled, examiner-blind, four-treatment arm, parallel design, clinical methodology development study to investigate the plaque removal efficacy of marketed manual toothbrushes in healthy, dentate participants. Changes in plaque level will be evaluated after first brushing, after two further single brushing events (Days 7 and 28) and following 7 and 28 days usage (twice daily brushing with assigned toothbrush treatment).
Supra-gingival plaque levels will be assessed using two established clinical measures: the Rustogi Modified Navy Plaque Index (RPI) and the 6-site Turesky Modified Quigley and Hein Plaque Index (TPI). Participants will abstain from oral hygiene for a period of 12-18 hours prior to each assessment visit. Participants with Day 0 pre-brushing mean RPI overall ≥ 0.6 will be stratified by their Day 0 pre-brushing RPI score (lower: mean RPI overall ≥ 0.6 to ≤ 0.8; higher: mean RPI overall; 0.8 to 1.0) and randomized to study treatment (Visit 2).
To standardize oral hygiene practice, eligible participants will complete a lead-in period (minimum 5 days) prior to Visit 2 during which they will brush with the toothbrush and regular fluoride toothpaste provided.
The safety and oral tolerability of each study toothbrush will be monitored after first use and over the 28-day usage period by review of reported treatment emergent adverse events (TEAEs).

Description
Inclusion Criteria:
An individual must meet all the following inclusion criteria to be eligible for enrollment into the study.
- Participant provision of a signed and dated informed consent document indicating that the participant has been informed of all pertinent aspects of the study before any assessment is performed.
- A participant who is willing and able to comply with scheduled visits, treatment plan and other study procedures.
- A participant in good general, mental and oral health with, in the opinion of the investigator or medically qualified designee, no clinically significant or relevant abnormalities in medical history or upon oral examination, or condition, that would impact the participant's safety, well-being or the outcome of the study, if they were to participate in the study, or affect the individual's ability to understand and follow study procedures and requirements.
- A participant with, in the opinion of the investigator or medically qualified designee, satisfactory oral hygiene based on oral examination.
- A participant who routinely uses a manual toothbrush for daily oral hygiene.
- VISIT 1 (Screening): A participant must have a) ≥ 20 natural, permanent teeth b) ≥ 40 gradable tooth surfaces (≥ 2/3rds of the tooth surface assessable for RPI).Third molars, fully crowned/ extensively restored, grossly carious, orthodontically-banded/bonded or abutment teeth and surfaces with calculus deposits which, in the opinion of the clinical examiner, would interfere with plaque assessment should not be included in the gradable surface count. Third molars can be included if, as a result tooth loss, they are functioning as second molars.
- VISIT 2 (Baseline): A participant must have a pre-brushing mean RPI ≥ 0.6 overall (that is, the mean over all gradable surfaces)
Exclusion Criteria:
An individual who meets any of the following exclusion criteria will not be eligible for enrollment into the study.
