An increase in the utilization of anesthesia and sedation medications by
non-anesthesiologists, including dentists, has grown dramatically. This has been prompted,
in part, by the need for pharmacological tools to address high levels of fear and anxiety
about dental care among the US population and the evidence of oral health disparities among
those who are fearful . Given the prevalence of dental fear in the general population and in
the various populations with the greatest burden of oral diseases, effective sedation
techniques are needed that are safe and effective in the hands of general dentists that make
up the "front line" in the efforts to reduce oral health disparities. This study is to
determine whether, when compared to a saline placebo, a single intraoral submucosal
administration of the benzodiazepine antagonist flumazenil (0. 2 mg) is capable of attenuating
in 10 minutes or less the central nervous system (CNS) depression produced by a paradigm of
stacked sublingual dosing of triazolam (3 doses of 0. 25 mg over 90 minutes).
