Clinical outcomes with bioactive agents alone or in combination with grafting or guided tissue regeneration.

AIM: The purpose of the present review was to determine the clinical effect of the use of bioactive agents (BAs) for the treatment of intra-osseous and furcation defects.
MATERIAL AND METHODS: The effectiveness of the BAs was evaluated when used in addition to open flap debridement either alone or in association with grafts and/or guided tissue regeneration (GTR). Among the included agents, recombinant human platelet-derived growth factor-BB (rhPDGF-BB), platelet-rich plasma (PRP), commercially available enamel matrix derivative (cEMD) and peptide P-15 (P-15) have been clinically tested for treating periodontal defects. RESULTS AND
CONCLUSIONS: The results of the present review indicate that: (1) cEMD either alone or in combination with grafts can be effectively used to treat intra-osseous defects and the clinical results appear to be stable long term; (2) the additional use of a graft seems to enhance the clinical outcome of cEMD; (3) the combined use of rhPDGF-BB and P-15 with a graft biomaterial has shown beneficial effects in intra-osseous defects; (4) contrasting results were reported for PRP and graft combinations; and (5) limited evidence supports the use of BAs either alone or in association with graft/GTR for the treatment of furcation defects.
