Does the diabetes status of an individual have effects on mechanical and biologic properties of platelet-rich fibrin? An in vitro comparative evaluation

Objective: Clinical research in the field of regeneration presents challenges for regulating inflammation and speeding up healing and regenerative processes, which are lacking in individuals with diabetes. Platelet-rich fibrin (PRF) has shown promising results in regeneration. Variations in its properties are attributed mainly to the centrifugation method and other parameters. Hence, the present in vitro study on leukocyte-PRF (L-PRF) and advanced-PRF (A-PRF) membranes, with varying protocols amongst diabetes, was conducted.

Method and materials: Sixty-four PRF membranes from 30 individual's venous blood samples (16 nondiabetic and 16 diabetic) were assessed for platelet parameters, tensile strength, strain, and growth factor release. The resulting data were statistically analyzed.

Results: The A-PRF membrane had better tensile strength, strain, and growth factor level in comparison with the L-PRF membrane in healthy individuals. Significantly (P < .05) higher strain and growth factor levels in the A-PRF membrane and marginally higher tensile strength in the L-PRF membrane were seen in diabetic individuals.

Conclusions: The nondiabetic A-PRF membrane had better tensile strength, strain, and growth factor release. Well-controlled diabetic individuals had higher growth factor release, suggesting the use of A-PRF membrane as a suitable autogenous regenerative material.
