Aim of the work:the aim of this study is to find out the changes in the percentage of the bone surface area in the regenerating interradicular bone which take place in association with using occlusive or modified perforated collagen membranes in management of grade II furcation defects in dogs. Materials and Methods: A total number of four adult clinically healthy mongrel dogs were included in the current study. Sixteen grade II critical-sized furcation defects were surgically createdin lower

In all four dogs, defects on the right quadrants were managed by ß-Tricalcium phosphate (ß-TCP) bone graft and occlusive collagen membrane and defects on the left quadrants were managed by ß-TCP bone graft and modified perforated collagen membrane. Results and conclusions: The obtained data revealed that modified perforated membrane had a positive better role in the regenerating of interradicular bone as revealed by significantly greater value of mean percentage of bone surface area which has taken place in association with it.
