简要总结
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.
详细描述
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.

结局指标
主要结局
Pulpal Anesthesia
时间窗: Continuous throughout dental treatment period (up to 60 minutes)
Number of participants who did not need rescue anesthesia to complete the study dental procedure, i.e. Kovacaine provided enough pulpal anesthesia to complete a dental procedure.
