The purpose of this study is to determine if the topical application to gingival tissue of the combination of benzocaine and tetracaine has a longer duration of local anesthetic activity than benzocaine alone.
In a blinded study, either benzocaine alone or the combination of benzocaine and tetracaine will be sprayed onto the gingival mucosal tissue. Onset and duration of local anesthesia will be evaluated over a one hour period using pin prick and quantitative sensory testing of heat (QST-heat) stimulation. Subjects will receive both treatments in a cross-over design with each session separated by 4-14 days. A total of 50 subjects (normal volunteers) will be evaluated.

The QST Heat-based "Duration of effect" was calculated by the length of time in minutes from onset of anesthesia to the absence of anesthesia where Onset of anesthesia was defined by PPT unless specific QST thresholds were not met. After Onset had been established, absence of analgesia or offset was the first of two time points with consecutive occurrences of regression or absence of analgesia. Reports of QST heat pain temperature by ≥ 3 °C of the Baseline QST indicated analgesia; while a report of similar (<3 °C) than Baseline indicated regression or absence of analgesia. Stage I outcome. | Posted | Mean | Standard Deviation | minutes | Up to one hour post-application |
