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.

Aims and objectives The aim of this prospective clinical study was to evaluate the response of type 2 diabetics to periodontal surgical therapy and to compare the treatment outcome with that of non-diabetics.Patients and methods A total of 20 type 2 diabetic and 20 non-diabetic patients with moderate to advanced periodontal disease were recruited in the study. Patients with probing pocket depth ≥ 5 mm in at least three adjacent teeth and with horizontal bone defects (as confirmed by radiographs) were subjected to periodontal surgery. Changes in clinical parameters such as gingival status, probing pocket depth, clinical attachment level, mobility, and position of the gingiva were evaluated 6 months post-operatively.Results Patients in both groups showed significant pocket depth reduction and clinical attachment gain as compared to baseline, however, no differences in the amount of improvement between the groups was seen.Interpretation and conclusions Type 2 diabetic patients respond to periodontal surgical procedures in a manner similar to that of non-diabetics provided good glycemic control and optimum oral hygiene are maintained.
