Which class of drugs is considered first-line for reducing dental anxiety?
Show answer and explanation
Correct answer: B. Benzodiazepines
- A. Antihistamines like hydroxyzine have mild sedative/anxiolytic effects but are second-line compared to benzodiazepines.
- B. Correct. Benzodiazepines (e.g., diazepam, triazolam) are the first-line pharmacologic agents for dental anxiety due to their anxiolytic, sedative, and amnestic properties.
- C. Beta-blockers may reduce some physical symptoms of anxiety (tachycardia, tremor) but are not standard for dental anxiety management.
- D. Opioids are analgesics, not anxiolytics, and are not first-line for dental anxiety.
