Comparative Evaluation of the Efficacy of Platelet-rich Fibrin and Calcium Phosphosilicate Putty alone and in Combination in the Treatment of Intrabony Defects: A Randomized Clinical and Radiographic Study.

BACKGROUND

Combination of platelet-rich fibrin (PRF) and bone substitutes for the treatment of intrabony pockets is based on sound biologic rationale. The present study aimed to explore the clinical and radiographic effectiveness of autologous PRF and calcium phosphosilicate (CPS) putty alone and in combination in treatment of intrabony defects.

MATERIALS AND METHODS

A total of 45 intrabony defects were selected and randomly divided into three groups. In Group I, mucoperiosteal flap elevation followed by placement of PRF was done. In Group II, mucoperiosteal flap elevation followed by placement of CPS putty was done. In Group III, mucoperiosteal flap elevation followed by placement of PRF and CPS putty was done. Clinical parameters such as gingival index (GI), pocket depth (PD), clinical attachment level (CAL), gingival marginal position and radiographic parameters such as bone fill, changes in crestal bone level, and defect depth resolution were recorded at baseline and after 6 months postoperatively.

RESULTS

Statistically significant changes in GI, PD reduction, CAL gain, defect fill, and defect depth resolution from baseline to 6 months were seen in all the three groups ( < 0.05). On intergroup comparison, no statistically significant changes were seen in all clinical parameters. However, the difference in defect fill and defect depth resolution between the Groups I and III and Group II and III was significant.

CONCLUSION

Within limitations of study, combination of PRF and CPS putty showed a significant improvement in PD reduction, CAL gain, and bone fill.
