Abstract

Aim: This study aims to assess the influence of external cold and vibration (Buzzy device) compared to the conventional injection technique on the perception of pain during local anesthesia administration in children.
Materials and Methods: Twenty-one children aged 6-11 years with bilateral decay in primary or permanent teeth needing restoration, extraction, or pulp therapy were randomly split into two groups. Group (A) received local anesthesia with the buzzy device on the first visit and conventional injection technique on the next visit, and group (B) received conventional injection technique on the first visit and local anesthesia with the buzzy device on the next visit. The face leg activity crying consolability (FLACC) scale and pulse oximeter were utilized for the objective evaluation, while the Wong-Baker faces pain scale (WBFPS) was used for the subjective assessment. The results were statistically examined.
Results: There was no statistically significant difference in pain score between the buzzy device and conventional methods using the WBFPS. After applying the two methods, there was no statistically significant difference observed between heart rates. Using the FLACC scale, there was no statistically significant difference concerning the two methods for the child's behavior during the injection of local anesthesia.
Conclusion: Buzzy devices can effectively control pain during nerve block injection technique. There is no difference in the buzzy device's effectiveness compared to the conventional injection technique in reducing children's pain during a nerve block injection.
