Abstract
Experience: The effect of the action of vibration in pain analgesia is relatively well established, however little is known about the real effect of vibration on pain reduction. Objective: To compare children’s reactions when undergoing dental local anesthesia using an anesthesia device that produces micro-vibrations. Method: Thirty children underwent two types of anesthesia: with and without vibration. The anesthetic procedures were filmed and consisted of maxillary posterior infiltration anesthesia. A combination of tests was used to evaluate the multidimensional character of fear, anxiety, and pain. The tests were applied before and after the anesthetic procedures. At the end of the second anesthesia session, the children reported their preferences regarding the use of vibration or not. Results: It was found that 90% of the children preferred anesthesia with vibration. A statistically significant difference was found in the Visual Analogue Scale (VAS) when comparing the mean values (p=0.04) using selective criteria at a 5% significance level. Conclusion: Vibration seems to have a positive influence on the children’s perception during local anesthetic procedures.
