Different Regenerative Responses of Two Platelet Concentrates in the Treatment of Human Periodontal Infrabony Defects: A Clinico-Radiographic Study.

Abstract

Background:Platelet concentrates usage in the treatment of intrabony defects has been improved due to advancement of research. Many generation of platelet concentrates were used, but research regarding advanced platelet-rich fibrin (A-PRF) regarding periodontal treatment is scanty.Aim:The purpose of the study was to evaluate and compare PRF and A-PRF in the treatment of human periodontal infrabony defects (IBDs) both clinically and radiographically.Materials and Methods:Twenty-eight patients having IBDs were divided into Group A (PRF) and Group B (A-PRF). Clinical parameters such as plaque index, gingival index, probing pocket depth (PPD), and clinical attachment level (CAL) were recorded at baseline and 3 and 6 months and radiographic examination at baseline and 6 months were also recorded to evaluate defect fill, resolution, and change in the alveolar crest height. Then, all the data were tabulated in a Microsoft Excel sheet and subjected to statistical analysis. Mean and standard deviations of the clinical and radiographic parameters were calculated, and unpaired t-test was performed to assess intergroup comparison at different time intervals.Results:Intragroup comparison showed statistically significant improvement in PPD and CAL at 3 and 6 months while statistically significant improvement was observed in mean defect fill and resolution in Group B.Conclusion:Individually, both the materials have shown promising results. However, statistically, PRF group (Group A) showed better treatment outcome in terms of bone fill and A-PRF group (Group B) in terms of soft tissue healing.
