title: Comparative clinical evaluation of combination anorganic bovine-derived hydroxyapatite matrix (ABM)/cell binding peptide (P-15) and open flap debridement (DEBR) in human periodontal osseous defects: a 6 month pilot study.
abstract: A synthetic cell binding peptide (P-15) combined with anorganic bovine-derived hydroxyapatite bone matrix (ABM) was compared to open flap debridement (DEBR) in human periodontal osseous defects. Following initial preparation procedures, two osseous defects per patient were treated randomly with one of the two procedures after surgical preparation. Appropriate periodontal maintenance schedules were followed, and at 6 months clinical and radiographic assessments for soft tissue and hard tissue were performed for documentation and finalization of treatment. Statistical analysis using Student's paired t-test analyses of patient mean value from 10 patients revealed that the combination ABM/P-15 grafts demonstrated significantly better mean defect fill of 3.4+/-1.7 mm (73.2%) versus a mean defect fill of 0.6 mm (15.8%) for defects treated with DEBR. Soft tissue findings showed significant differences among treatments with ABM/P-15 compared to DEBR. These results suggest that the use of the P-15 synthetic cell-binding peptide combined with ABM yields better clinical results than DEBR.
