- Abstract
THE PURPOSE OF THIS STUDY was to compare the clinical effectiveness of connective tissue grafts including periosteum used as a mechanical barrier for guided periodontal tissue regeneration and coronally positioned flaps in the treatment of Class II furcation defects. A total of 28 furcation defects were treated; 14 received a periosteal barrier and 14 received a coronally positioned flap. Reentry surgeries were performed at 6 months. No statistically significant differences were found preoperatively between the two treatment groups with respect to clinical parameters and osseous measurements. Postsurgically, both treatment modalities resulted in a significant decrease in probing depth and a significant gain in clinical attachment, but the differences observed were not statistically significant. The periosteal barrier group presented with a significantly better gain in vertical components of the alveolar bone (1.93 ± 0.15 mm and 0.20 ± 0.26 mm for periosteal barrier and coronally positioned flap groups, respectively; P ≤ 0.001) and horizontal components of the alveolar bone (1.60 ± 0.21 mm and 0.13 ± 0.90 mm for periosteal barrier and coronally positioned flap groups, respectively; P ≤ 0.001). The results of this trial indicate that similar clinical resolution of Class II furcation defects can be obtained with periosteal barriers and coronally positioned flaps. Periosteal barriers, however, are a better treatment alternative in achieving bone fill of the furcation area.
