Background: The present study evaluated the healing of enamel matrix derivative (EMD) proteins in the treatment of periodontal lesions with deep intrabony defects.
Methods: Ten deep intrabony defects in 7 periodontal patients were treated and followed for 1 year. The sites had a probing depth (PD) > or = 8 mm; clinical attachment level (CAL) > or = 9 mm, and intrabony component depth > or = 5 mm.
