Clinical Performance of the DentalVibe® Injection System on Pain Perception During Local Anesthesia in Children.

Purpose: The purpose of this study was to clinically compare injection pain experience in children using three methods. Methods: This was a randomized clinical trial conducted among 150 children (81 girls, 69 boys), from seven to 14 years of age, who required operative dental treatment. Fifty patients were randomized into one of three groups: DentalVibe® , manual stimulation, or no stimulation (control). During the injection, the pulse rate and perceived pain, using the Wong Baker FACES Pain Rating Scale were recorded. Generalized linear models were used to analyze the data. Results: We found a statistically significant decrease in the FACES score in the DentalVibe® group compared to the control group and the manual stimulation group ( P <0.001). Injection type (mandibular inferior alveolar block/long buccal injections versus maxillary infiltration injections) did not differ statistically in pain perception. The heart rate in the DentalVibe® group showed no significant difference compared to the other groups at all time points. Conclusion: The DentalVibe® may reduce pain for pediatric patients receiving dental injections.
