   When a tooth has very deep periodontal pockets it may not be possible to fully remove the dental plaque/tartar/calculus from the tooth's root surface with scaling alone. In open flap debridement (OFD) the gum is peeled back to make it possible for the dentist to see and ensure full removal of tartar/calculus from these difficult to access areas ...

   Removal of microbial plaque and calculus is necessary to establish periodontal health. The first step in the treatment of periodontitis involves nonsurgical cleaning below the gum line with a procedure called "root surface instrumentation" or "RSI", this causes a mechanical disturbance to the bacterial biofilm below the gumline.
