Which instrument combination is not typically used for basic periodontal charting?

• A. Periodontal probe, explorer, and mouth mirror.
• B. Periodontal probe, scaler, and mouth mirror.
• C. Explorer, scaler, and mirror.
• D. Probe, explorer, and curet.

Answer: (B)

The key idea is that basic periodontal charting relies on measuring and observing the tissues around each tooth, using tools dedicated to assessment. The periodontal probe is used to determine pocket depths, the mouth mirror improves visibility, and the explorer helps detect surface irregularities and calculus during the exam. Instruments like scalers and curets are designed for removing calculus and for instrumentation, not for recording measurements or charting findings. Including a scaler in a charting set introduces a tool whose primary role isn’t charting, so that combination isn’t typical for basic periodontal charting. In charting practice you’d stick with the probe, mirror, and explorer, while scalers or curets would be used later if debridement or root planing is needed.
