Comparison of computer controlled local anesthetic delivery and traditional injection regarding disruptive behaviour, pain, anxiety and biochemical parameters: a randomized controlled trial

The study herein evaluated the effects of infiltrative anesthesia administered via different ways. Resultantly, the pain and anxiety were monitored using psychometric, physiological and biochemical methods. Sixty children aged 7–11 years (8.73 ± 1.38) were included in the study. They were divided into 2 groups (n = 30): Traditional injection (control group), and computer controlled local analgesic delivery (CCLAD)(study group). Pulse, oxygen saturation (SpO2), and salivary cortisol levels were recorded, and the scales data (Visual Analogue Scale (VAS), Wong-Baker Faces Rating Pain Scale (WBS), Modified Child Dental Anxiety Scale (MCDAS) and Face, Leg, Activity, Cry, Consolability Behavioral Pain Assessment Scale (FLACC)) were evaluated. The data were statistically analyzed. Age and gender had not much impact on the measured parameters (p > 0.05). SpO2 values in both groups were not significantly different (p > 0.05). Pulse, VAS, WBS, MCDAS, FLACC and salivary cortisol values were increased after the anesthesia in control group (p < 0.05). WBS, MCDAS, FLACC and salivary cortisol values were decreased after the anesthesia in study group compared to the control (p < 0.05). It was inferred that computer controlled local analgesic delivery system could be preferred in pediatric patients because of reduced pain and anxiety.
