Evaluation of Injectable Beta-tricalcium Phosphate Clinically in Treatment of Grade II Furcation Involvement

Evaluation of Injectable Beta- Tricalcium Phosphate as an Occlusive Barrier Membrane in Treatment of Grade ii Furcation Involvement (Clinical and Radiographic Study)

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.

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.

Inclusion Criteria:

• • Presence of a lower molar with critical size grade II furcation defect (15) with a horizontal component of 4 mm and a vertical component of 4 to 6 mm (18), detected using Naber's probe and William's periodontal probe.

  • Patient's age between 30 - 50 years.
  • Both sexes.
  • The patient should be psychologically accepting the procedures.
  • Patients should be systemically free.

Exclusion Criteria:

• • Uncooperative patients regarding oral hygiene measures performance.
