Evaluation of Modified Minimally Invasive Surgical Technique and Platelet Rich Fibrin With or Without Vitamin Pool A and C for Management of Periodontal Intrabony Defects

Intrabony Periodontal Defect

This study aims to assess clinical and radiographic outcomes after the use of vitamins A and C with PRF versus PRF alone in the treatment of periodontal intrabony defect.

Sites with deep intrabony defects were considered to be at a higher risk of disease progression if patients did not receive any systematic periodontal therapy. Treatment of intrabony defects is an important therapeutic goal of periodontal therapy. The optimal outcome of treatment in intrabony defects is considered to be the absence of bleeding on probing, the presence of shallow pockets associated with periodontal regeneration and limited soft tissue recession.The minimally invasive surgical technique is designed to mobilize just the defect-associated papilla and to reduce flap extension as much as possible. The modified minimally invasive surgical technique has been proposed to further reduce invasiveness and patient side effects by limiting the incision line to the buccal side. This technique fulfilled the maintenance of the interdental papillary height by minimizing its tendency to collapse, increased the likelihood of primary wound closure and reduced the chances of gingival recession. Platelet-rich fibrin is a powerful healing biomaterial with inherent regenerative capacity and can be used in the treatment of periodontal intrabony defects. Vitamin C is found to be able to induce osteogenic differentiation and maturation of progenitor cells of PDL without using osteogenic filling material. Also, Vitamin A has a unique property of de-differentiating adult cells into pluripotent cells. Since combination therapies have been shown to be effective in the regeneration of periodontal defects, this study will evaluate the synergetic effect of vitamins A and C on the periodontal regeneration, together with the most widely used regenerative biomaterial; Platelet-rich fibrin, as an attempt for finding the gold standard in the treatment of intra-bony defects.
