AIM: To compare paediatric patients' pain during needle insertion and injection in inferior alveoler nerve block (IANB) anaesthesia injected by either a traditional syringe (TS) or the DentalVibe Injection Comfort System (DV).


STUDY DESIGN: the study was a randomised controlled crossover clinical trial, comprised of 60 children aged 6-12 requiring an operative procedure with IANB anaesthesia on their mandibular molars bilaterally. One of the molar teeth was treated with TS and the contralateral tooth was treated with DV. On each visit, subjective and objective pain was evaluated using the Wond-Baker Faces Pain Rating Scale (PRS) and the Face, Legg, Cry, Consolability Scale (FLACC Scale). Patients were asked which anaesthesia technique they preferred. Data were analysed using Wilcoxon signed rank, Spearman correlation, and Mann-Whitney U tests.

RESULTS: There were no statistically significant differences for pain evalution during needle insertion and injection of each injection system. However, a negative correlation was found on the FLACC between age and pain scores during injection after using DV.

CONCLUSION: Paediatric patients experienced similar pain during IANB anaesthesia administered with TS and DV. With increased age, pain values reduced during anaesthetic agent injection with DV according to FLACC. The traditional procedure was preferred to DV in paediatric patients.
