Aim: To evaluate and compare the pain perception by the pediatric patients, while experiencing computerized injection device computerized syringe and the conventional injection technique during dental clinical procedures Methodology: Forty children aged 10‑14 years requiring local anaesthesia on two sides of the dental arch were included in the study. The patients served as their own control, and on the appointed day through computerized injection technique local anesthesia was injected and on the second day, anesthesia was achieved with the help of traditional method. Visual analogue scale (VAS) and faces pain rating scale (FRS) were used to evaluate pain perception of pediatric patients. Along with this, various other physiological parameters were also taken into consideration. Results: Paired t‑test discovered a statistically significant variance in the pain acuity in pediatric patients using VAS and FRS scales to compare amid computerized and conventional technique. No statistically significant difference was observed when physiological parameters (heart rate, blood pressure) were compared at various intervals between the computerized and the conventional technique Conclusion: Computerized controlled injection technique provides less painful injections when compared to the conventional injection technique.
