Question 1

Which class of antihypertensive medications is most commonly associated with drug-induced gingival overgrowth that can interfere with orofacial myofunctional therapy?

Accepted Answer

Calcium channel blockers

Answer

Calcium channel blockers such as nifedipine and amlodipine are the most common antihypertensives linked to gingival overgrowth.

Question 2

A patient undergoing orofacial myofunctional therapy reports chronic use of opioid analgesics. Which oral side effect should the COM clinician monitor most closely?

Accepted Answer

Xerostomia and reduced mucosal lubrication

Answer

Opioids reduce salivary flow via anticholinergic mechanisms, causing xerostomia that compromises oral tissue health.

Question 3

Botulinum toxin type A injections used in bruxism management primarily work by:

Accepted Answer

Inhibiting acetylcholine release at the neuromuscular junction

Answer

Botulinum toxin prevents ACh vesicle fusion at the neuromuscular junction, producing temporary chemodenervation of targeted muscles.

Question 4

Which over-the-counter antihistamine most significantly impairs salivary flow and could complicate myofunctional exercises requiring adequate oral lubrication?

Accepted Answer

Diphenhydramine (Benadryl)

Answer

Diphenhydramine is a first-generation antihistamine with strong anticholinergic activity, producing pronounced xerostomia.

Question 5

A child patient's parent reports the child takes methylphenidate for ADHD. How might this medication affect orofacial myofunctional therapy sessions?

Accepted Answer

It typically improves focus but may cause bruxism or jaw clenching

Answer

Stimulant medications like methylphenidate can cause bruxism and jaw clenching as side effects while generally improving focus during the medicated window.
