The study is a randomized, controlled clinical trial. Patients were randomly divided into two equal groups, Group I (Test group): included seven Grade II furcation defects treated by beta tricalcium phosphate bone cement only.~Group II (Control group): included seven Grade II furcation defects treated with granulated beta tricalcium phosphate bone graft covered by resorbable collagen membrane.
This study will be conducted to evaluate clinically and radiographically the use of PD VitalOs cement® bone graft in the treatment of class II furcation defects comparing with Hydroxyapatite bone graft and biodegradable collagen membrane in the treatment of class II furcation defects.
