Non Surgical Periodontal Therapy

Scaling and root planing, otherwise known as conventional periodontal therapy, non-surgical periodontal therapy, or deep cleaning, is the process of removing or eliminating the etiologic agents – dental plaque, its products, and calculus – which cause inflammation, thus helping to establish a periodontium that is free of disease. Periodontal scalers and periodontal curettes are some of the tools involved.
