Objective: The purpose of this clinical study was to assess the efficacy of Drynaria quercifolia plant (rhizome) extract as bone forming substitute in periodontal intraosseous defects. Material and methods: Twenty patients with chronic periodontitis with intraosseous defects were selected for the study. The sites were randomly divided into control and experimental group. Control group was treated with open flap debridement (OFD) whereas the experimental group with OFD and placement of drynaria plant extract. Probing pocket depth (PPD), relative attachment level (RAL), radiographic evaluation including the depth of the bone defect and the percentage of bone defect fill were recorded for both the groups, at baseline, three and six months. Results: The control and experimental groups from baseline to six months showed the PPD reduction by 3.2 mm (45.71%) and 4.6 mm (63.01%), respectively. RAL gain by 3.9 mm (30.47%) and 5.5mm(42.97% ), respectively; gain in bone fill level was 2.22 ± 0.6 (29.23 %) and 3.71 ± 0.54 mm (44.97 %), respectively. Conclusion: The Probing pocket depth reduction and relative attachment level gain after six months were more for the experimental group as compared to the control group and the difference was statistically significant.
