Comparision of injection pain caused by the DentalVibe Injection System versus a traditional syringe for inferior alveolar nerve block anaesthesia in paediatric patients

ABSTRACT

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). MATERIALS AND

Methods

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.
