A Comparative Cytocompatibility Assessment of Leukocyte-Platelet-Rich Fibrin (L-PRF) and Injectable Platelet-Rich Fibrin (I-PRF) on the Pre-osteoblastic MG-63 Cell Line in Chronic Periodontitis Patients: An In Vitro Study

AimThe aim of the study is to assess the cellular viability of various concentrations of different platelet concentrates on pre-osteoblastic MG-63 cells.Materials and methodsIn this in-vitro experiment, blood samples from 21 individuals with chronic periodontitis were taken and centrifuged according to Choukroun and Miron's protocol to prepare L-PRF and I-PRF, respectively. The methyl thiazolyl tetrazolium (MTT) test was used to determine the viability of 0%, 1%, 2%, 4%, 8%, 10%, and 20% concentrations of L-PRF and I-PRF on MG-63 cells.ResultsThe 20% L-PRF had the lowest percentage of cell viability (90.429 +/- 2.06), and the 1% I-PRF had the highest percentage (98.918 +/- 0.54), with no statistically significant difference (p>0.05).ConclusionAccording to the findings of the current study, both L-PRF and I-PRF provide favorable outcomes in terms of the viability of MG-63 cells in chronic periodontitis patients that may be utilized for regenerative purposes such as periodontal osseous defects and mucogingival surgeries. Incorporating these platelet concentrates with bone grafts results in enhanced regenerative outcomes.
