Clinical Evaluation of Coronally Advanced Flap With or Without Advance-Platelet Rich Fibrin Membrane in the Treatment of Miller's Class-II Localized Gingival Recession: A Clinical Study.

ABSTRACT

INTRODUCTION:  Periodontal treatment focuses on maintaining a patient's natural teeth and gums. The gingival margin recedes to a point apical to the tooth in 20%-100% of people. Coronally advanced flap (CAF) is one of several effective treatments for this condition. This surgery covers the tooth root with gingiva. The predictability of this surgery depends on the blood supply, donor tissue, and surgical skills. Platelet concentrates, which include platelet-rich fibrin (PRF), majority of the time is used for various regenerative therapies. Since no bovine thrombin or anticoagulant is needed, its manufacturing is simpler, cheaper, and less biochemically modified than PRP. Platelet-rich fibrin (PRF) is a fibrin matrix that progressively releases platelet cells and cytokines. AIM: The present study aimed to evaluate the efficacy of CAF with and without A-PRF in the treatment of Miller's class-II localized gingival recession. MATERIALS AND METHODS: Twenty patients were chosen who had Miller's class-II localized gingival recession. A random number generator was used to place patients into either the "test" or "control" group. Treatment for both Groups A and B included a coronally advanced flap, but only Group A additionally got autologous platelet-rich fibrin (A-PRF). After receiving a detailed explanation of the treatment process, the patient signed an informed consent form. Complete medical and dental histories were taken to see whether there were any absolute or relative contraindications. RESULTS:  Following treatment with either method in the current study, gingival thickness improved considerably. The percentage of root coverage did not change considerably between the two groups. The clinical result might likely have been different if other factors, such as platelet concentration and PRF consistency, had been examined in the current investigation. Furthermore, there was no histological examination of the healing process. As a result, we are unsure of the extent to which PRF affects how effectively connective tissue attaches. CONCLUSION: The additional use of A-PRF membrane did not provide additional benefits in terms of root coverage outcomes compared with CAF alone. The use of A-PRF membranes significantly reduced the recession depth.
