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. All subjects received therapy prior to surgery and had a plaque score (PI) < or = 10%. Full thickness flaps were elevated buccally and lingually, granulation tissue was removed from the defects, and the root surfaces were planed. A 24% EDTA gel was applied followed by the enamel matrix protein preparation. The flaps were closed with interrupted sutures. The patients rinsed with a chlorhexidine solution twice a day for 6 weeks. They were recalled every 2 weeks for 6 months for professional tooth cleaning and then every 4 weeks for an additional 6 months. The experimental sites were re-examined 6 and 12 months after regenerative surgery.
RESULTS: At the 1-year examination, the mean CAL gain was 6.5 mm, the mean PD was 3.2 mm, and mean radiographic bone fill was 4.7 mm.
CONCLUSIONS: The application of enamel matrix proteins in combination with open flap curettage and root planing resulted in a gain of CAL and bone fill in deep intrabony defects.
