Outcome Measures

Primary Outcomes (1)

  • Complete Root Coverage

    The percentage of sites showing complete root coverage will be calculated as a percent of treated defects with the marginal gingival located at or above the cement-enamel junction compared to the total defects treated.

    6-months

Secondary Outcomes (9)

  • Clinical Periodontal Parameters

    Baseline, 6-weeks, 4-months, and 6-months

  • Clinical Periodontal Parameters

    Baseline, 6-weeks, 4-months, and 6-months

  • Clinical Periodontal Parameters

    Baseline, 6-weeks, 4-months, and 6-months

  • Clinical Periodontal Parameters

    Baseline, 6-weeks, 4-months, and 6-months

  • Pain Levels

    1-week, 2-weeks, 4-weeks, and 6-months

  • +4 more secondary outcomes
