About

Healing of apicomarginal defects using 2 different formulations of PRF i.e PRF -high and PRF-medium will be assessed and compared using 2D and 3D criteria. Also, in vitro evaluation of the PRF formulations and quality of life will be compared between the two groups.

Full description

Periapical surgery is a viable treatment option in teeth with persistent apical periodontitis, especially in cases which fail to heal by non surgical treatment. Kim and Kratchman classified periradicular lesions into categories A-F. Lesions A-C are of endodontic origin without any periodontal pockets and vary with respect to the size of periapical radiolucency while D-F are combined endodontic - periodontal origin and are ranked accoding to the magnitude of periodontal breakdown. Type F defects are commonly referred to as apicomarginal defects and have worst prognosis among all. The lower success rate is attributed to the apical migration of junctional epithelium and intrusion of non osteogenic connective tissue into the periapical region.

Recently, autologous platelet concentrates have been used instead of the conventional practice of using GTR barrier membranes for treating apicomarginal defects. Till date no human study has compared platelet formulations; PRF-high ( 2700 rpm for 12minutes) and PRF-medium (1500 rpm for 14minutes) to see any difference in the bony healing and the quality of life between the two groups and no study have assessed bony healing of the periapical defect with periodontal communication with the use of CBCT.

Thus, the aim of the present study is to investigate the effect of 2 different formulations of PRF on quality of life and healing outcome of periapical defects with periodontal communications . Also, in vitro histological and immunohistochemical evaluation and comparison of the clots prepared from different centrifugation protocols will be done .
