Enamel Matrix Derivative and Xenograft for Mandibular Molar Furcation Defects

This randomized controlled clinical trial aims to compare two regenerative surgical approaches for the treatment of mandibular molar Class II furcation defects in patients with periodontitis. Eligible furcation defects will be randomly assigned to receive either xenograft bone combined with enamel matrix derivative (EMD) or xenograft bone combined with a collagen membrane. Both approaches are used to support periodontal tissue regeneration. Participants will be followed for approximately 7 months. The study will evaluate postoperative pain and patient-reported satisfaction, periodontal clinical parameters, changes in furcation defect volume and relative bone density on cone-beam computed tomography (CBCT), and changes in gingival crevicular fluid TWEAK levels. Clinical and radiographic outcomes will be assessed before surgery and during follow-up, including at 3 and 6 months after surgery. The study is intended to determine whether xenograft bone combined with EMD provides clinical, radiographic, biological, and patient-reported outcomes comparable or superior to xenograft bone combined with a collagen membrane in the regenerative treatment of mandibular molar Class II furcation defects.
