This is a split-mouth, randomized, controlled clinical trial that aims to evaluate the clinical efficacy of platelet-rich fibrin (PRF) membranes in conjunction with coronally advanced flap (CAF) in treating maxillary gingival recession defects.

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
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
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
