Phase 2
Completed
Conditions
Furcation Defects
Interventions
Procedure: OFD with Platelet rich fibrin (PRF)
Procedure: OFD with Platelet rich fibrin (PRF)+1% Metformin (Drug) in gel form
Procedure: Open flap debridement (OFD)
Registration Number

Brief Summary

The aim of the present trial is to evaluate the efficacy of PRF with 1% MF in treatment of mandibular class II furcation defects and its comparison to PRF and access therapy alone.

Detailed Description

Background: For improving efficacy and outcomes of regenerative therapy for furcation defects, various materials has been investigated in addition to access therapy. Platelet-rich fibrin (PRF) having concentrated growth factors and cytokines and Metformin (MF), an efficacious member of biguanide group are known to enhance periodontal regeneration. The aim of the present trial is to evaluate the efficacy of PRF with 1% MF in treatment of mandibular class II furcation defects and its comparison to PRF and access therapy alone.

Methods: This randomized trial was conducted on 75 patients with mandibular class II furcation defects. Defects were surgically treated with either access therapy alone (Group 1), access therapy+PRF (Group 2), and access therapy+ PRF+1% MF (Group 3). Clinical parameters like probing depth (PD), relative clinical attachment level {vertical (RVCAL) and horizontal (RHCAL)}, modified sulcus bleeding index (mSBI) and site specific plaque index (PI) were evaluated at baseline and 9 months post-operatively. Radiological assessment of bone defect fill was done at baseline and 9 months.
