Human Histologic Repair and Regeneration After Biologic Preparation of Diseased Root Surfaces

摘要

Case reports of two human volunteers are presented with histologic evaluation of the results 28 days after periodontal flap surgery. Three specimens were treated with phosphate-buffered physiological saline applied to the diseased root surface for one minute (control), and three specimens were treated with an experimental combination of 2% bile salt followed by 5% human plasma fraction for one minute each. There are indications that a connective tissue new attachment may be possible following the biologic preparation of diseased root surfaces.
