Background: Local anesthetic injection considered one of the most anxiety-provoking procedures especially for pediatric dental patients.Many techniques had been suggested to decrease the pain during local anesthetic injection; one of them is using a Vibro-tactile device as Dentalvibe® which claims to decrease the pain during local anesthetic injection.Aims: The aim of this study was to compare the pain perceived during maxillary infiltration local anesthesia injection with the aid of DentalVibe comfort system and that perceived during maxillary infiltration injection alone in pediatric dental patients.Design: The study included 19 children from both genders, aged 5-6 years old. Each child received two injections.The injections were divided randomly into two methods: Dentalvibe (DV): maxillary infiltration injection with the aid of Dentalvibe and traditional (TR): receiving the same previous injections without the use of Dentalvibe.Pain was assessed objectively using the FLACC® and subjectively using Wong-Baker faces® pain scales.Results:Statistical analysis for both objective and subjective pain assessment using Chi-square and Fisher's Exact tests found a statistically significant reduction in pain ratings for injections with the Dentalvibe when compared to traditional injections.Conclusions: Using DentalVibe comfort system in maxillary infiltration dental local anesthesia showed less pain when compared to traditional method. In addition, gender had no effect on the pain felt during injection using DentalVibe comfort system when compared to traditional method
