What researchers measure

Primary outcomes

  1. Gingival Margin Plaque Index

    Scale 0 to 100% of tooth gingival margin covered by plaque. (0=no plaque, 100%=100% of the tooth's gingival margin is covered in plaque). The lower the score less dental plaque is present along the gum line and therefore the better the performance of the study treatment.

    Time frame: 1 day
