Five-year results following treatment of intrabony defects with enamel matrix proteins and guided tissue regeneration

A modest 1-year difference between the outcomes of simple flap surgery (OFD) and surgery with enamel matrix derivative (EMD) disappeared by 5 years. In this study, 56 patients with single intrabony ...
