Different Regenerative Responses of Two Platelet Concentrates in the Treatment of Human Periodontal Infrabony...

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.

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.

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.

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.

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.
