Alveolar Bone Loss, Periodontal Attachment Loss, Periodontitis
Conditions
Brief summary
This study aims to verify the effectiveness of Trafermin (recombinant human basic fibroblast growth factor) in stimulating regeneration of periodontal tissue lost by periodontitis and to evaluate the safety of such stimulation.
