Various regenerative procedures used for the treatment of intabony defects.The Aim of this study is to compare the treatment outcome of bioactive silica graft with platelet rich fibrin Vs bioactive silica graft in the treatment of intrabony defects in patients with diabetes mellitus.

Platelet rich fibrin has emerged as one of the promising regenerative material.It is a second generation platelet concentrate and is defined as an autologous leucocyte-and platelet-rich fibrin biomaterial.Platelet-rich fibrin membrane consists of a fibrin 3-D polymerized matrix in a specific structure ,with the incorporation of almost all the platelets and more than half of leucocytes along with growth factors.It enhance the stabilization and revascularization of the flaps and grafts.

Bioactive silica graft (Novabone dental putty )is being used for regenerative procedures is a premixed composite of bioactive calcium -phospho-silicate particulate which is composed solely of elements that exist naturally in normal bone (ca,p,na,si,o) and an absorbable binder which is a combination of polyethylene glycol and glycerine.Treatment of intrabony defects with bioactive silica graft has led to clinically and statistically significant probing depth reduction ,relative attachment level gain and radiographic osseous defect fill.
