Which technique should be used to allow for movement when probing maxillary molars?

• A. Use a longer lever
• B. Hold the probe vertically
• C. Rotate the wrist
• D. Pivot the fulcrum to allow for movement

Answer: (D)

Pivoting the fulcrum to allow for movement gives you a stable base that you can rotate around while guiding the probe tip along the complex surfaces of the maxillary molars. The fulcrum acts as your fixed point of support; by shifting and rotating it, you can adjust the angle and direction of the probe without losing control, which is essential for reaching buccal, palatal, mesial, and distal surfaces on these posterior teeth. This technique enables precise, gentle probing with consistent pressure, helping you obtain accurate depths. In contrast, a longer lever makes control harder; holding the probe vertically is not practical for accessing the molars; and simply rotating the wrist does not provide the same stable base for safe, accurate measurement.
