About

The present study was designed to evaluate the combined efficacy of PRF and 1% ALN in the treatment of mandibular degree II furcation defects when compared with PRF and open flap debridement (OFD) alone.

Full description

Background: Various regenerative materials have been introduced and tested in the treatment of furcation defects. Platelet-rich fibrin (PRF) is a reservoir of growth factors and cytokines which are the key factors for regeneration of bone and maturation of the soft tissue. Alendronate (ALN), a potent member of bisphosphonate group is known to promote tissue regeneration by inhibiting osteoclastic bone resorption and promoting osteoblastogenesis. The present study was designed to evaluate the combined efficacy of PRF and 1% ALN in the treatment of mandibular degree II furcation defects when compared with PRF and open flap debridement (OFD) alone.

Methods: Seventy two mandibular furcation defects were treated with either OFD alone (Group 1), OFD with PRF (Group 2), and OFD with PRF+1% ALN (Group 3). Clinical parameters; site specific plaque index (PI), modified sulcus bleeding index (mSBI), probing depth (PD), relative vertical attachment level (RVAL) and relative horizontal attachment level (RHAL), intrabony defect depth (IBD) were recorded at baseline before surgery and 9 months post-operatively. Percentage radiographic defect fill was evaluated at baseline and 9 months.

Enrollment: 72 patients

Sex: All

Ages: 30 to 50 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Immunocompromised individuals;
• Those having unacceptable oral hygiene (plaque index [PI] >1.5).
• Teeth with furcation involvement, non-vital teeth, and carious teeth indicated for restorations and mobility of at least grade II
