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 and calculus (scaling 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.
