Common
Benzodiazepines
A thorough review of dental anesthetics
and their reversals
by Tammy Smit, CRNA

Course description
Sedation for dental treatments and procedures is on the rise, and is often expected by
patients. Practitioners offering sedation often request additional information on commonly
used pharmaceutical agents. The benzodiazepine class of medications is the most commonly
used type of medication used for either oral or intravenous sedation. This course revisits the
pharmacology of these prescribed sedatives, including midazolam, diazepam and triazolam.

Introduction
Pain and anxiety have always been associated with dental treatment. It has been
increasingly more common for anxious patients to seek out sedation dentistry; in fact, surveys
suggest that around 60% of the population suffers from anxiety, fear or phobia toward
dental procedures.1 Moreover, these anxious behaviors lead to avoidance of care, resulting
in compromised dental health. Because of their fears, as many as 5-7% of the population
never or rarely visits a dentist.2 This ultimately causes bad oral health and potentially creates
advanced disease states, beginning a cycle of anxiety and declining oral health and making
it even more challenging when these patients actually seek dental care.
