De novo surgical debridement of furcation roofs by fine diamond bur was introduced. Routine presurgical preparation of teeth and a strict plaque control program were performed for at least six weeks before surgery. A papillary conserved full thickness mucoperiosteal flap was used in all cases. In addition to conventional debridement, odontoplasty was performed on the furcation areas with a diamond bur to eradicate inaccessible fissures or grooves and ensure calculus-free root surfaces. Following debridement, the bony defects were filled with DFDBA and covered with polytetrafluoroethylene (ePTFE) membranes. The flaps were then closed by interproximal sutures coronally positioned through the contact point. The ePTFE membranes were removed 6 to 7 weeks after operation. Clinical parameters such as probing depth (PD), gingival recession (GR), probing attachment level (PAL), tooth mobility (TM), and periapical x-ray were recorded at the baseline and 0, 3, 6, 9, and 12 months after removal of the ePTFE membrane. The results showed a significant increase in the probing attachment level and radiographic evidence of bone fill at the furcation sites. Thus, the addition of fine diamond bur debridement on the furcation in the GTR procedure with DFDBA grafting may be effective in the treatment of grade III furcation involvement. |
