Which of the following is NOT a WREB dental hygiene practical examination required for licensure in Washington?

The answer highlights that oral hygiene assessment is not a specific practical examination required by the Western Regional Examination Board (WREB) for dental hygiene licensure in Washington. While an oral hygiene assessment is indeed an essential part of the dental hygiene process and may be evaluated in other contexts, it does not constitute a separately designated practical examination component by WREB.

In contrast, the other choices represent key competencies assessed by WREB. Patient evaluation clinical competency involves assessing a patient's overall health and oral conditions, which is vital for effective dental hygiene practice. Prophylaxis clinical competency focuses on the skills needed to perform professional dental cleanings and preventive care, ensuring the hygienist can safely and effectively remove plaque and calculus. Anesthesia clinical competency evaluates the hygienist’s ability to administer local anesthetics safely and effectively, which is a crucial skill in modern dental hygiene practice.

These components are critical for ensuring that candidates are adequately prepared to provide high-quality care to patients. Each of these practical examinations directly reflects the essential skills required for functioning effectively as a licensed dental hygienist in Washington State.
