NCT04611282

Brief Summary

The purpose of this study was to compare the effectiveness of microsurgical and macrosurgical approaches on CPFs plus SCTGs for the treatment of localized gingival recession defects (Miller class I or II) over the course of 6 months based on clinical periodontal parameters, periodontal phenotypes, and the postoperative complaints and satisfaction levels of the patients. We hypothesized that root coverage achieved through microsurgery in Miller I or II gingival recessions would improve clinical periodontal outcomes and the periodontal phenotype, with greater postoperative comfort and aesthetic satisfaction in comparison with conventional macrosurgical techniques. Miller Class I and II gingival recession defects, at least 3.0 mm deep, were selected and randomly assigned to receive micro or macrosurgical techniques. Both techniques were performed using a coronally positioned flap with a subepithelial connective tissue graft. Plaque and gingival indices, gingival recession depth and width, probing pocket depth, bleeding on probing, clinical attachment level, width of keratinized gingiva, aesthetic score and percentage of root coverage, postoperative complaints, and satisfaction of the participants completing the study were evaluated at follow-up 1st, 3rd and 6th months.

Outcome Measures

Primary Outcomes (1)

  • Percentage of root coverage

    The primary endpoint for efficacy of the gingival recession was the percentage of root coverage at baseline and 6-months postsurgery, as measured by gingival recession depth.

    6 months

Secondary Outcomes (4)

  • Changes in Gingival recession depth

    6 months

  • Changes in Gingival recession width

    6 months

  • Changes in Keratinized gingival width

    6 months

  • visual analog scale

    6 months

ACTIVE COMPARATOR

All defects were treated with a CPF plus an SCTG by the same investigator using macrosurgery technique.

Procedure: surgical techniques in the treatment of localized gingival recession defects.

Interventions

Micro or macrosurgical echniques were performed using a coronally positioned flap with a subepithelial connective tissue graft.
