Use of platelet gel with connective tissue grafts for root coverage: a randomized-controlled trial.
BACKGROUND
Platelet-rich plasma (PRP) was speculated to be a promoter of periodontal regeneration. There are only a few clinical comparative studies using PRP in the treatment of gingival recession.


OBJECTIVE
The aim of the present study was to compare connective tissue graft (CTG)+PRP with CTG alone in the treatment of gingival recession.


METHODS
Forty patients with Miller I/II recessions were included. Each recession was randomly treated with either CTG+PRP or CTG. Clinical variables were recorded at baseline and at 6 weeks, 6 and 12 months. Root coverage (RC) and attachment gain (AG) were also calculated.


RESULTS
Probing depth, recession depth, clinical attachment level, keratinized tissue width and recession width (RW) were improved in both study groups. However, no difference was observed between groups, except RW. RW in the control group was statistically lower than the test group at all follow-up periods.


CONCLUSIONS
Treatment of recession with CTG or a CTG-PRP combination resulted in favourable clinical outcomes. However, no difference could be found between CTG and CTG+PRP. Whether much longer follow-up studies with higher statistical power may change these results remains questionable.
