Outcome Measures

Primary Outcomes (6)

  • Effect on dental plaque

    Dental plaque (%) will be assessed according to the O'Leary method on each side of the mouth.

    Change from Visit 1 (Day 1) to Visit 2 (Day 29).

  • Effect on gingival bleeding

    Gingival bleeding (%) will be assessed on each side of the mouth.

    Change from Visit 1 (Day 1) to Visit 2 (Day 29).

  • Effect on pocket depth

    Pocket depth (mm) will be assessed on each side of the mouth.

    Change from Visit 1 (Day 1) to Visit 2 (Day 29).

  • Interdental hygiene assessment by subject

    Interdental hygiene on each side of the mouth at Visit 2 compared to Visit 1 will be assessed by the subject using a 4-point scale (0: no change, -1: slightly improvement, 2: improvement, 3: significant improvement)

    Visit 2 (Day 29).

  • Adverse events recording

    Adverse events occurrence will be determined by the subject spontaneous reporting, the investigator's non-leading questioning and his/her clinical evaluation

    From Visit 1 (Day 1) to Visit 2 (Day 29)

  • Acceptability Questionnaire assessment

    Acceptability questionnaire regarding the use of the interdental brushes will be completed by the subject.

    Visit 2 (Day 29)
