About

The purpose of this study was to determine the safety and efficacy of Kovacaine Mist (3% tetracaine HCl with 0.05% oxymetazoline HCl) for anesthesia of the maxillary teeth for dental procedures.

Full description

The primary objective of this single-center, randomized, double-blind, active-controlled, parallel-group study was to determine if Kovacaine Mist provided anesthesia of the maxillary teeth sufficient for the performance of dental procedures. Secondary objectives included a determination of whether Kovacaine Mist provided anesthesia of the soft tissue and to evaluate the safety and tolerability of Kovacaine Mist and sham injection as compared to sham nasal spray and 2% lidocaine hydrochloride with 1:100,000 epinephrine submucosal injection and as determined by changes in vital signs and reports of side effects and adverse events.
