Scaling and root planing, also known as conventional periodontal therapy, non-surgical periodontal therapy or deep cleaning, is a procedure involving removal of dental plaque, calculus or debridement and then smoothing, or planing, of the exposed surfaces of the roots, removing cementum or dentine that is impregnated with calculus, toxins, or microorganisms, the agents that cause inflammation. It is a part of non-surgical periodontal therapy. This helps to establish a periodontium that is in remission of periodontal disease. Periodontal scalers and periodontal curettes are some of the tools involved. A regular, non-deep teeth cleaning includes tooth scaling, tooth polishing, and debridement if too much tartar has accumulated, but does not include root planing.
