Background/Purpose:
The present study aimed to investigate plastic tubes without additives as alternatives to glass and silica-coated plastic tubes, in the production of PRF membranes.
Materials And Methods:
Nine blood samples were collected from eight volunteers (n = 8) separated into three groups, according to tube material: glass, silica-coated plastic, and plastic without additives. In each group, the samples were centrifuged using different relative centrifugation forces: L-PRF (700 g/12 min), A-PRF (200 g/14 min), and A-PRF + (200 g/8 min). The generated membranes were evaluated by histomorphometry, considering the fibrin network, platelet aggregates, and cellular morphology, by light microscopy. The ultrastructural cellular morphology integrity was evaluated by transmission electron microscopy.
Results:
The L-PRF (p < 0.019) and A-PRF (p < 0.001) membranes showed a significantly lower fibrin network density in plastic tubes without additives compared to glass and silica-coated plastic tubes. Plastic tubes without additives revealed a significantly higher platelet percentage, regardless of the protocol (p < 0.005). In all groups, TEM analysis showed preserved normal morphological ultrastructure, maintaining the integrity of cellular components.
Conclusion:
Plastic tubes without additives offer a viable alternative for producing PRF membranes. They exhibited a higher platelet density and demonstrated fibrin network and cellular morphology similar to those of glass and silica-coated plastic tubes, irrespective of the centrifugation protocol.
