The primary purpose of root planning in periodontal therapy is to:

The primary purpose of root planing in periodontal therapy focuses on removing calculus and biofilm from the root surfaces of teeth. This procedure is essential because the presence of these deposits can contribute to the progression of periodontal disease by perpetuating inflammation and infection in the surrounding gum tissue. By effectively cleaning the root surfaces, root planing helps to reduce bacterial load and diminish the inflammatory response, thereby supporting the overall health of the periodontal tissues.

While there are other important aspects of periodontal therapy, such as aiding in healing and reattachment of the gingiva, evaluating the depth of periodontal pockets, and assessing tooth mobility, these are secondary effects or considerations following the primary objective of root planing. The removal of calculus and biofilm sets the stage for improved healing and recovery of the periodontal tissues, allowing for better outcomes in periodontal treatment.
