Multi‐centre, randomized clinical trial on efficacy and safety of recombinant human platelet‐derived growth factor with β ‐tricalcium phosphate in human intra‐osseous periodontal defects. J Clin Periodontol 2011; 38: 163–172. doi: 10.1111/j.1600‐051X.2010.01639.x. Abstract Aim: The objective of the study was to evaluate the safety and efficacy of a formulation containing recombinant human platelet‐derived growth factor (rhPDGF‐BB) and β ‐tricalcium phosphate ( β ‐TCP) in patients with periodontal defects and to compare it with those of β ‐TCP alone. Materials and Methods: In this double‐blind, prospective, parallel, active‐controlled, randomized, multi‐centre clinical trial, 54 patients with periodontal osseous defects were randomly assigned to rhPDGF‐BB+ β ‐TCP or β ‐TCP. Following periodontal surgery, respective implantation was performed. The primary and secondary end points of treatment were evaluated at the third and the sixth month. Results: Among the outcome measures, the extent of linear bone growth ( p <0.01) and per cent bone fill ( p <0.004) at the sixth month over baseline were significantly higher in the rhPDGF‐BB+ β ‐TCP group when compared with the β ‐TCP group. Similarly, it also resulted in significantly higher area under the curve clinical attachment level gain at 0–6 months ( p <0.01), CAL gain and greater reduction in probing depth at the third and the sixth month than that with β ‐TCP treatment alone. The incidence of adverse events was similar in both the groups and no serious adverse events were reported in any of the patients. Conclusions: rhPDGF‐BB+ β ‐TCP is safe and effective in the treatment of periodontal defects. It increases bone formation and soft tissue healing (clinicaltrials.gov, number NCT00496847; CTRI No.: CTRI/2008/091/000152).
