Avaliação comparativa em relação a dor de crianças submetidas à anestesia odontológica com e sem vibração

Abstract

The fear and anxiety during dental treatments are often related to pain regarding local dental anesthetic procedures. As there are many studies about the effect of vibration on pain analgesia, this thesis aimed to compare whether children anesthetized with a dental anesthetic device that produced micro-vibrations during the anesthetic procedure would behave differently when compared to the regular procedure. Thirty children, aged between 7 and 12 years underwent two sessions of local dental anesthesia each, with and without the vibration device. A single researcher, pediatric dentist, managed the anesthetic procedures that consisted of maxillary infiltration anesthesia and which were recorded on video. Due to the multidimensional nature of fear, anxiety and pain, multiple tests were used to evaluate them, such as Child Fear Survey Schedule – Dental Subscale – CFSS-DS, Facial Anxiety Scale – FAS , the SEM Scale Sound, Eyes and Motor, the Visual Analogue Scale (VAS) and the Frankl Scale. The scales were applied twice, before and after anesthesia. After the second anesthetic session, the preference of the children regarding the use or not of vibration was assessed and it was found that 90% of children preferred anesthesia using vibration. There was a statistically significant difference considering the Visual Analogue Scale (VAS) in the comparison of means (p = 0,04) considering a significance level of 5%. As a result, we concluded that the use of vibration seemed to result in a positive influence on the perception of the children regarding the anesthetic procedure, as almost the totality opted by the device with vibration, which lead us to the conclusion that the use of vibration resulted in a less painful local dental anesthesia.
