National Board Dental Hygiene Examination (NBDHE) Dental Hygienist Practice Test

The use of an air polisher typically requires careful consideration of a patient’s overall health and specific conditions. Among the listed options, a patient with hypotension would not have their condition contraindicating the use of an air polisher.

Hypotension, or low blood pressure, largely pertains to the cardiovascular system and does not directly relate to the oral cavity or the effects of an air polisher. This equipment operates via high-pressure air and a slightly abrasive powder, which may be relevant to other oral health conditions, but it does not inherently pose a risk to someone with hypotension.

In contrast, patients with exposed cementum may be more sensitive to abrasive polishing techniques, while those on a sodium-restricted diet should avoid the sodium-containing powders commonly used in air polishers. Respiratory issues can also create complications since the aerosolized particles could be inhaled, potentially exacerbating pre-existing conditions.

Thus, hypotension is the safest of these conditions in relation to the use of an air polisher, allowing dental hygienists to administer this procedure without significant risk to the patient's health.
