Aim and objective: To evaluate the pain perception and comfort of patient during local anesthesia (LA) delivery using Buzzy system and conventional syringe. Materials and methods: Fifty children aged 5 to 10 years were randomly divided into two groups, the main inclusion criteria being administration of LA for dental treatment. Parameters include Wong Baker face pain reading scale (WBFPRS) for subjective evaluation and pulse oximeter and face leg activity crying consolability (FLACC) scale for objective evaluation. The values obtained were statistically analyzed. Results: FLACC score was higher in conventional group as compared to the Buzzy group, which was statistically significant. Conclusion: External cold and vibration via Buzzy can reduce pain and anxiety during LA delivery.
