Aim: The objective of this study was to determine the pain produced from needle insertion at bilateral labial site prepared with topical application of 2% lidocaine gel, 20% benzocaine gel, and placebo paste at subsequent visits in a same patient.
Materials and Methods: Forty healthy individuals aged 18-30 years old were subjected to three sessions in which they were treated with 2% lidocaine gel, 20% benzocaine gel, and placebo paste. in all sessions, a 26-gauge needle was inserted in maxillary labial mucosa before and 1 min after the drug application. Immediately, after needle insertion, participants indicated pain intensity on visual analog scale (VAS).
Results and Conclusions: Pain responses were compared based on subjects' self-report using VAS. Results showed that lidocaine and benzocaine were equally effective, and both were better than placebo in reducing the pain of needle insertion.
