Masaeli R, et al. - Experts provided a comparative outlook on different biomaterials applicable in regeneration of furcations with a focus on enamel matrix derivative (EMD)(a protein complex widely used in the regeneration of different periodontal defects). The evidence to find the best combination of biomaterials to treat furcation defects was provided by the results. If EMD was combined with β-TCP/HA alloplastic bone grafts, the best results were obtained. Tissue swelling and patient discomfort after treatment was also reduced with EMD.
