Study Arms (2)

Open flap debridement with osteoplasty

EXPERIMENTAL

In this arm, periodontal surgery consists of open flap debridement followed by osteoplasty in the furcation entrance area.

Procedure: Open flap debridement with osteoplastyProcedure: Open flap debridement without osteoplasty

Open flap debridement without osteoplasty

ACTIVE COMPARATOR

In this arm, periodontal surgery consists of open flap debridement only. No osteoplasty will be performed.

Procedure: Open flap debridement with osteoplastyProcedure: Open flap debridement without osteoplasty

Interventions

Treatment of furcation grade II defect with open flap debridement followed by osteoplasty treatment. Osteoplasty includes altering the bone buccal to the furcation opening to \>90 degrees relative to the apico-coronal axis of the toot.
