Periodontal scaling and root planing “involves instrumentation of the crown and root surfaces or the teeth to remove deposit and/or roughness and is therapeutic, not prophylactic, in nature.
Root planning is the definitive procedure designed to remove plaque and calculus from these surfaces. It is indicated for patients with periodontal disease and is for removal of cementum and dentin that is rough, and/or permeated by calculus or contaminated with toxins or microorganisms. Some soft tissue removal occurs.”
Periodontal disease is episodic; destructive episodes can be triggered by stress, disease, or other systemic problems. It is not curable but can be controlled much like diabetes.
