The aim of this study is to evaluate the pain perception while administering local infiltration, in children undergoing dental extractions, using a new auto-controlled injection system.
Children in the age range of 6–10 years with teeth indicated for extraction were recruited and allocated to either Group I, computer-controlled injection system (auto system with special cartridge and compatible disposable 30-gauge, 10 mm needles), or Group II, traditional system (30-gauge, 10 mm needle and disposable traditional syringe). Local infiltration was administered and extraction performed after 3 min. The time of administration (TOA) of infiltrate was noted whereas anxiety and pain in both groups were assessed using the Modified Child Dental Anxiety Faces Scale simplified (MCDAS (f)), pulse rate, Faces Pain Scale-Revised (FPS-R), and Face, Legs, Activity, Cry, Consolability (FLACC) Scale.
