Use of autologous platelet rich plasma to treat gingival recession in esthetic periodontal surgery

Background: Multiple approaches have been used to replace lost, damaged or diseased gingival tissues. Coronally advanced flap (CAF) and the use of guided tissue regeneration are among the successfully used surgical techniques to treat gingival recession. Platelet rich plasma (PRP), containing autologous growth factors, has been shown to promote soft-tissue healing. Therefore, the purpose of this study was to evaluate the efficacy of PRP in combination with CAF in the treatment of gingival recession. Materials and Methods: A total of 15 systemically healthy patients with buccal Miller's class I and class II gingival recession in cuspids or premolars participated in the study. CAF procedure was performed and PRP with collagen sponge was placed over the defect. Clinical parameters such as recession depth, recession width, surface area, width of keratinized gingival (KG), clinical attachment level (CAL), probing depth, plaque index and gingival index were evaluated at 3, 6 and 9 months post-surgery. The percentage of root coverage was calculated. Results: The results of this study suggest that the CAF procedure provides a predictable and simple technique in the treatment of localized Class I and Class II gingival recession. The additional application of PRP does significantly increase the width of KG and gain in clinical attachment. Conclusion: CAF procedure is a predictable and simple technique in the treatment of gingival recession and the additional application of PRP does significantly increase the width of KG and gain in CAL. The long-term benefits following surgical treatment of such defects needs to be determined further.
