BACKGROUND: This study investigates the impact of enamel matrix derivative (EMD) proteins on the outcome of a minimally invasive surgical technique (MIST) for the treatment of intrabony defects. METHODS:Thirty patients who presented with intrabony defects were randomly assigned to treatment with: 1) MIST plus EMD or 2) MIST alone. Probing depth (PD), position of the gingival margin (PGM), and relative clinical attachment level (RCAL) were evaluated at 3 and 6 months after treatment. Radiographs and markers in gingival crevicular fluid associated with periodontal regeneration were also evaluated. RESULTS:Significant PD reductions, RCAL gains, and no changes in PGM were obtained at 3 and 6 months in both groups. Clinical and radiographic evaluations and levels of mediators of wound healing did not present differences between therapies at any time. CONCLUSION: The use of EMD did not provide superior benefits on the outcome of the minimally invasive surgical approach for the treatment of intrabony defects.
