Identify the four-step process of removing calculus and smoothing root surfaces below the gumline.

• A. Scaling and Root Planing
• B. Root Canal Therapy
• C. Prophylaxis
• D. Periodontal Debridement

Answer: (A)

This item is asking about the procedure that removes calculus below the gumline and smooths the tooth roots to promote healing. The best description is scaling and root planing. Scaling involves removing plaque and calculus from the tooth surfaces, including below the gingival margin, using manual instruments or ultrasonic tips. Root planing follows, which smooths the rough cementum on the root surfaces to eliminate embedded deposits and toxin-laden irregularities, creating a clean, smooth surface that discourages bacterial re-adhesion and helps the surrounding tissues reattach. This combination is the standard non-surgical periodontal therapy for subgingival deposits and pocket inflammation, typically performed in stages (quadrants) with local anesthesia. Root canal therapy focuses on the tooth’s pulp, not the roots and supporting structures. Prophylaxis is a preventive cleaning above the gumline. Periodontal debridement is a broader term that can include subgingival cleaning, but the specific process described—removing calculus below the gumline and smoothing the root surfaces—is most accurately termed scaling and root planing.
