Abstract
CONTEXT: Platelet concentrates are rich in growth factors that assist in regenerative medicine to promote healing and tissue regeneration. Similarly, partially demineralized tooth is a storehouse of many growth factors, assisting in bone regeneration. Hence, the present study aimed to quantify the release of growth factors from different platelet concentrates individually and when mixed with a partially demineralized tooth matrix. METHOD: Human growth factors such as bFGF, EGF, PDGF-AB, TGF-beta-1, and VEGF-A present in platelet-rich fibrin and injectable platelet-rich fibrin from young and old male and female donors were quantified separately. Then these platelet concentrates were then mixed with a partially demineralized tooth matrix, which was powdered using a Smart Dentin Grinder. An enzyme-linked immunosorbent assay was used for the quantification of growth factors. RESULTS: The release of growth factors, such as platelet-rich fibrin and injectable platelet-rich fibrin, was not statistically significant; however, it was significantly greater when i-PRF was mixed with a partially demineralized tooth matrix. CONCLUSION: The study revealed that the expression of growth factors was significantly greater when a partially demineralized tooth matrix was mixed with injectable platelet-rich fibrin than when combined with platelet-rich fibrin.
