Aim: This study aims to evaluate and compare the structural characteristics of platelet-rich fibrin (PRF) prepared by two different protocols in nondiabetic and controlled diabetic patients. Materials and methods: Ten milliliters of blood sample were drawn from 30 participants [nondiabetic (15), controlled diabetic (15)]. Five milliliters of blood were transferred to two dry vacutainers. For each patient two PRF clots were obtained using the standard protocol [leukocyte-rich platelet-rich fibrin (L-PRF)] and the low-speed concept [advanced platelet-rich fibrin (A-PRF)]. These were processed for light microscopy analysis to estimate the width of the fibrin meshwork. Results: In controlled diabetic patients, A-PRF showed significantly more dense fibrin network compared to those of L-PRF. The difference between L-PRF and A-PRF in nondiabetic patients was not statistically significant. Conclusion: Modification done to the standard centrifugation protocol, by increasing time and reducing speed, favors an increase in the dense fibrin network of A-PRF in diabetic patients. Clinical significance: Modified centrifugation protocol proves to be favorable in controlled diabetic patients for periodontal regeneration.
