A patient requires root planing. Which of the following statements about the root planing procedure is INCORRECT?

Root planing is a periodontal therapeutic procedure that involves instrumentation of the exposed root surface to remove subgingival calculus and contaminated/necrotic cementum, smooth the root surface, and disrupt/remove the bacterial biofilm. It is performed on the ROOT (cementum and dentin), NOT on the enamel surface. Removing calculus from enamel is scaling (supragingival), which is a different procedure. Root planing specifically targets the root surface below the gingival margin. The procedure aims to create a smooth, biologically compatible root surface that facilitates reattachment of periodontal tissues and resolution of inflammation.
