Summary

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.

Conditions

  • Class II Furcation Defect

Interventions

PROCEDURE

Periodontal Regenerative Surgery With Xenograft and Enamel Matrix Derivative

Periodontal regenerative surgery is performed using xenograft bone combined with enamel matrix derivative (EMD). After flap elevation, thorough defect debridement, and root surface conditioning with 24% EDTA for 2 minutes, EMD is applied to the root surface associated with the furcation defect. The xenograft bone is mixed with EMD and placed to completely fill the defect. The flap is then repositioned and sutured.

PROCEDURE

Periodontal Regenerative Surgery With Xenograft and Collagen Membrane

Periodontal regenerative surgery is performed using xenograft bone combined with a resorbable collagen membrane. After flap elevation, thorough defect debridement, and root surface conditioning with 24% EDTA for 2 minutes, the xenograft bone is mixed with sterile saline and placed to completely fill the furcation defect. A trimmed resorbable collagen membrane is positioned to completely cover the defect and secured before flap repositioning and suturing.
