A patient requires root planing. All of the following are correct regarding root planing EXCEPT:
Show answer and explanation
Correct answer: A. Remove calculus from enamel
✓ A) Remove calculus from enamel is the EXCEPTION.
Root planing involves instrumentation of the root surfaces — cementum and sometimes dentin — to remove calculus, endotoxins, and contaminated cementum. Enamel is located coronal to the CEJ and above the gingival margin; it is addressed during scaling (supragingival or coronal subgingival), not root planing. Root planing is specifically a subgingival procedure on root surfaces (cementum/dentin).
