Sensitivity experienced by a client during power-driven instrumentation is most likely due to which of the following?

Question

Quizplus · Accepted Answer

Incorrect adaptation can create sensitivity. If the tooth-to-working end angle is greater than 15 degrees, energy is emitted that can create sensitivity. Intraoral or extraoral fulcrum placement should not affect sensitivity, although extraoral fulcrum placement facilitates lighter pressure with precision thin inserts. Methodical activation tends to refer to the motions used to cover the root surface with periodontal debridement to ensure calculus and biofilm removal is thorough. Generally, as long as the working end is in motion at all times over the tooth, sensitivity should not be felt. Faster activation to smooth a tooth should not, in itself, create sensitivity. All stroke directions (vertical, horizontal, oblique) are appropriate as long as the proper tooth-to-working end angulation is maintained.
