The aim of periodontal treatment is to regenerate periodontium. Regenerative treatments include the use of plasma that is rich in growth factors (PRGF). Materials & Methods: In a randomized clinical trial, 20 three-walled intrabony defects from five patients with moderate periodontitis were randomly assigned to three groups. Patients in the control group underwent debridement of lesions. In the first treatment group, the defects were debrided and cenomembrane was applied. The third group was

Measures of vertical probing depth (VPD), vertical clinical attachment level (VCAL), gingival index (GI; Sinless and Loe) and radiographic index (by digital subtraction) were made preoperatively and 6 months post-surgery. Wilcoxon signed-ranks and Chi-square tests were used for analyzing quantitative and qualitative variables, respectively. Results: All three groups showed improvements in all measures except GI. Intra-group comparison for clinical attachment level (CAL) indicated significant difference in all groups before and after surgery (P<0.05); there was no correlation in CAL among groups before surgery Intra-group comparison demonstrated significant differences in all three groups before and after surgery (P<0.001). A statistically significant difference was found in radiographic indices among the groups post-surgery (P=0.009). Conclusion: The use of PRGF was associated with improvements in all parameters but not for GI.
