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.
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.
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.
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.
血小板浓缩物富含生长因子,有助于再生医学促进愈合和组织再生。同样,部分脱矿牙是多种生长因子的储存库,有助于骨再生。因此,本研究旨在分别量化不同血小板浓缩物以及与部分脱矿牙基质混合时生长因子的释放量。
分别对年轻和老年男性及女性供体的富血小板纤维蛋白和可注射富血小板纤维蛋白中存在的人类生长因子如碱性成纤维细胞生长因子(bFGF)、表皮生长因子(EGF)、血小板衍生生长因子AB(PDGF-AB)、转化生长因子β-1(TGF-β-1)和血管内皮生长因子A(VEGF-A)进行定量。然后将这些血小板浓缩物与使用智能牙本质研磨机磨成粉末的部分脱矿牙基质混合。采用酶联免疫吸附测定法对生长因子进行定量。
富血小板纤维蛋白和可注射富血小板纤维蛋白等生长因子的释放量无统计学意义;然而,当可注射富血小板纤维蛋白与部分脱矿牙基质混合时,释放量显著更高。
研究表明,部分脱矿牙基质与可注射富血小板纤维蛋白混合时生长因子的表达明显高于与富血小板纤维蛋白混合时。
