Ace the FPC 2: 2026 PSR & Probing Practice – Smile Your Way to Success!

During walking stroke technique, the probe should stay in the sulcus as you move around the tooth, using light, even pressure. This minimizes tissue trauma and keeps readings consistent. The statement that the probe is not removed from the sulcus with each stroke reflects this practice—removing it would repeatedly traumatize the tissue and disrupt the measurement.

In contrast, actions like removing and reinserting after every stroke, probing deeply to the bottom of the sulcus, or scrubbing the tooth with the tip are not part of proper walking stroke technique. They can cause tissue injury, distort measurements, and compromise the efficiency and comfort of the exam.
