BACKGROUND: Aggressive periodontitis is a specific type of periodontitis with clearly identifiable clinical characteristics such as rapid attachment loss, bone destruction and familial aggregation. Regeneration of mineralized tissues affected by aggressive periodontitis comprises a major scientific and clinical challenge. In recent years some evidence has been provided that bioactive glass is also capable of supporting the regenerative healing of periodontal lesions. OBJECTIVE: The aim of this clinical and radiological prospective study was to evaluate the efficacy of bioactive glass in the treatment of intra-bony defects in patients with localized aggressive periodontitis. METHODS:Twelve localized aggressive periodontitis patients with bilaterally located three-walled intra-bony defect depth = 2 mm, preoperative probing depths = 5 mm were randomly treated either with the bioactive glass or without the bioactive glass. The clinical parameters plaque index, gingival index, probing depth, gingival recession, clinical attachment level, and mobility were recorded prior to surgery as well as 12 months after surgery. Intraoral radiographs were digitized to evaluate the bone defect depth at baseline and 12 months after the surgery. RESULTS: After 12 months, a reduction in probing depth of 3.92 + 0.313 mm (P < 0.001) and a gain in clinical attachment level of 4.42+0358mm (P < 0.001) were registered in the test group. In the control group, a reduction in probing depth of 2.5 +0.230mm (P <0.001) and a gain in clinical attachment level of 2.58 + 0.149 mm (P <0.001) was recorded. Radiographically, the defects were found to be filled by 2.587 + 0.218 mm (P < 0.001) in the test group and by 0.1792 + 0.031mm (P < 0.001) in the control group. Changes in gingival recession showed no significant differences. . CONCLUSION: Highly significant improvements in the parameters Probing depth, Clinical attachment level, and Bone defect depth were recorded after 12 months, with regenerative material.
