Text: When compared to baseline, the 12-month results indicated that, while both treatment modalities resulted in significant changes in all clinical parameters (gingival index, bleeding on probing, probing depth, clinical attachment level, and intrabony defect fill ; P < 0. 001), the test group exhibited statistically significant changes compared to the control sites in probing depth reduction : 4. 7 + / - 1. 6 mm versus 3. 7 + / - 2. 0 mm (P < 0. 05) ; clinical attachment gain : 3. 4 + / - 1. 7 mm versus 2. 0 + / - 1. 2 mm (P < 0. 001) ; and vertical relative attachment gain : 70. 3 % + / - 23. 4 % versus 45. 5 % + / - 29. 4 % (P < 0. 001).
