Optimally, natural tooth structures should be used to repair a dental defect. If this is not possible, the objective should shifted to creating the optimal circumstances for healing the defect with normal tissues or repairing it with a material that has the closest properties to the lost tissues. The objectives of repairing furcation perforations are to seal the dentin defect and provide suitable conditions for formation of a new periodontal attachment. Some materials may provide adequate seal but may interfere with the formation of periodontal reattachment while others may initiate formation of new bone and periodontal attachment but cannot adequately seal the dentin defect. This may result in leakage of bacteria and their by-products into the lesion with eventual failure. Since the furcation perforation involves different types of inter-related tissues, each tissue within the defect should be considered separately. Artificial floor technique applies the biological concept for the repair of furcation perforations considering the periodontal wound and the dentinal wound of the defect separately. This new concept allows for a better understanding for the management of furcation perforation.
