Abstract
Background and objectives: Dental phobia is a widespread issue that impacts a large portion of the world's population. As a result, various solutions have been proposed, such as applying topical anesthesia before the injection. However, there are paradoxical findings in different studies regarding the significance of pain control in dentistry. This study aims to evaluate the effect of Benzocaine Gel 20% on reducing pain for inferior alveolar nerve block.
Materials and methods: In the current double-blinded clinical trial, patients were randomly divided into two groups: the study group received 20% Benzocaine Gel (Master Dent) while the control negative group received Fluoride Gel (Master Dent AFP). An inferior alveolar nerve block injection was done afterward. The level of pain was assessed using Visual Analogue Scale (VAS). Data were analyzed using SPSS version 16.
Results: 329 patients were included of which, 149 (45.3%) and 180 (54.7%) individuals were in the control negative and intervention groups, respectively. The VAS was 73.97 ± 14.01 in the control negative and 60.68 ± 19.1 in the intervention group, which was significantly different (P = 0.001).
Conclusion: This investigation suggests that topical anesthetic substance 20% Benzocaine Gel can efficiently reduce injection pain and patients can become more comfortable during the procedure.
