Efficacy of vibrotactile device Dentalvibe in the assessment of pain during local anaesthesia in pediatric dental patients in comparison to conventional techniques: A comparative clinical study

According to the ''gate control'' approach, pain can be minimized by activating bigger diameter nerve fibers with appropriate coldness, warmth, rubbing, pressure, or vibration. : The present study investigated the efficacy of a vibrotactile device, Dentalvibe (DV), for needle-related procedural pain in comparison to conventional techniques (CCLAD, needle, topical jelly, vibraject, and Nitrous oxide inhalation sedation) of local anaesthesia in paediatric patients. 150 children aged 8 -12 years participated in a randomized controlled clinical study and divided into 6 test groups. Pain perception and comfort were assessed using the visual analog scale (VAS) and the 10-point scale, respectively. The pain perception was compared between the groups, and results were calculated based on the mean outcome. The results showed a significant reduction in pain with dental vibe compared to other techniques, whereas similar results were shown by nitrous oxide inhalation sedation (NIOS) and dental vibe. Our study shows that the vibration technique with the DentalVibe device can be used as a simple and efficient method to alleviate pain associated with dental injections compared to traditional local anaesthetic techniques.
