ABSTRACT:
Objective: This study was directed to compare the efficacy of VibraJect (VJ) and DentalVibe (DV) comfort systems and Topical anesthesia (TA) (20% benzocaine) in relieving of pain associated with local injection in children.
Subjects and methods: A total of 150 children (87 boys and 63 girls), who were attending for dental treatment in the pediatric dental clinic, were selected. Subjects equally divided according to used method into three groups (50 each). Fifty Subjects received into local anesthetic injections with VJ. Fifty Subjects received into local anesthetic (LA) injections with DV comfort system. Fifty Subjects received into local anesthetic injections with TA. Pain during injection was evaluated subjectively using Wong-Baker FACES pain rating scale by showing the scale to the child and asking him/her to choose a face that best described his/her feeling. Pain also had been objectively evaluated using face, leg, activity, cry and consolability (FLACC) scale by observing the child behavior during anesthesia administration.
Results: This study revealed that vibration applied using the VJ and DV decreased pain associated with a LA injection delivered via infiltration and nerve block. Subjects in the VJ and DV groups had significantly lower pain scores than those in the control (TA) group.
Conclusion: In this study, the VJ and DV appeared to reduce pain during LA injection without causing anxiety.
