ABSTRACT Introduction: Association between pulp and periodontal lesion is termed as endo-perio lesion. Treatment of intra-bony defect can be done by GTR. Methodology: The present study was conducted on 180 patients suffering from endo-perio lesion. They were divided into two groups namely the ones treated by PRF and the other one treated with T-PRF. Follow-up was taken at 3 and 6 months interval. The results thus obtained were analyzed statistically using SPSS version 21.0 (IBM. Chicago, USA) and unpaired t test. The level of implication was set less than 0.05. Results: Mean change in probing depth at period of 3 months in group 1 is 2-15 while after 6 months is 2.74. P value is 0.91 which is highly insignificant. Similarly relative attachment level at 3 months is 1.96 and at 6 months is 2.63. P value is 0.73. Conclusion: No statistically significant results were observed in term of baseline attachment measurements.
