Study arms

  • Active comparator
    coronally advanced flap with connective tissue graft

    After randomization a subepithelial connective tissue graft along with coronally advanced flap is applied to one maxillary quadrant to cover the recession.

    Procedure: Gingival coverage using coronally advanced flap and a connective tissue graft

  • Experimental
    coronally advanced flap with platelet rich fibrin membranes

    After randomization platelet rich fibrin membranes along with coronally advanced flap are applied to the other maxillary quadrant to cover the recession.

    Procedure: Gingival coverage using coronally advanced flap and platelet rich fibrin membranes

Interventions

  • ProcedureGingival coverage using coronally advanced flap and a connective tissue graft

    A coronally advanced flap is applied for recession coverage in the maxilla in a split-mouth randomized trial using a subepithelial connective tissue graft

  • ProcedureGingival coverage using coronally advanced flap and platelet rich fibrin membranes

    A coronally advanced flap is applied for recession coverage in the maxilla in a split-mouth randomized trial using platelet rich fibrin membranes

What researchers measure

Primary outcomes

  1. Increase in gingival height (recession coverage)

    The measurements of the increase in gingival height (recession coverage) using a linear evaluation (corono-apical direction) with a periodontal probe (Merrit-B; Hu-Friedy, Chicago, IL, USA) at the interventions sites to the nearest 0.5 mm. Registration of the recession height was done before treatment and after 6 weeks.

    Time frame: six weeks

  2. Shrinkage in gingival height

    To assess the shrinkage of the gingival height, the amount of gingival height vestibular to the treated teeth in a corono-apical direction was measured after the surgery and after six months.

    Time frame: six months

Secondary outcomes

  1. Postoperative pain visual analog scores (VAS) and surgery time

    This questionnaire used 100 mm visual analog scores VAS to evaluate the amount of pain, ranging from 0 (no pain) to 10 (worst pain imaginable), and the amount of swelling. Patients were asked to fill in the VAS scales at day 7 and day 14 at suture removal. The time of surgery was measured of both treatment options. Timing started at the moment of first incision until the last suture.

    Time frame: two weeks
