Objective: This randomized, prospective, blinded study compared pain in children following dental treatment under general anesthesia (GA) using 1 of 2 established analgesia methods.
Methods: Patients age 4 to 7 years were randomly assigned to a control group (intravenous [IV] analgesics) or experimental group (IV analgesics and intrapapillary local anesthetic infiltrations) between July 2017 and February 2018. During recovery from surgery, Faces, Legs, Activity, Cry, and Consolability (FLACC) scores were recorded upon regaining consciousness and reassessed every 15 minutes until discharge. Overall pain occurrence (FLACC ≥1) and moderate/severe pain occurrence (FLACC ≥4) were analyzed using mixed effects logistic regression (N = 88).
Results: The experimental group had a 17% lower overall pain occurrence than the control group (16 vs 33%; p = .02). Moderate/severe pain occurrence between the groups was not significant (9 vs 22%; p = .23). The dental treatment subjects received (number of completed stainless steel crowns, extractions, and/or pulpotomies) did not significantly affect pain occurrence.
Conclusion: Local anesthesia intrapapillary infiltrations around stainless steel crowns decrease overall pain occurrence but not moderate/severe pain occurrence following dental treatment under GA in pediatric patients.
