Periodontal Regeneration in Humans Using Recombinant Human Platelet‐ Derived Growth Factor‐BB (rhPDGF‐BB) and Allogenic Bone

Use of purified rhPDGF-BB mixed with bone allograft results in robust periodontal regeneration in both Class II furcations and interproximal intrabony defects. This is the first report of periodontal regeneration demonstrated histologically in human Class II furcation defects.
