Abstract
Objectives
To evaluate pain, disruptive behavior, and anxiety in children undergoing different local dental anesthetic techniques.
Methods
This randomized/parallel clinical trial analyzed three groups of patients (9–12 years old) (n = 35) who received infiltrative anesthesia using conventional (CA), vibrational (VBA), and computer-controlled techniques (CCLAD). The outcomes were pain self-perception (Wong-Baker Faces Pain Rating Scale (WBF); Numerical Ranting Scale (NRS)), disruptive behavior (Face, Legg, Activity, Crying, Consolability Scale (FLACC)), anxiety (Corah’s Dental Anxiety Scale; modified Venham Picture test (VPTm)), and physiological parameters (systolic (SBP)/diastolic pressure (DBP); heart rate (HR); oxygen saturation (SpO2); respiratory rate (RR)). Statistical analysis was accomplished using Kruskall-Wallis test and ANOVA for repeated measures (α = 0.05).
Results
Dental anxiety levels at the baseline were similar for all patients. CA promoted less pain than VBA in WBF (p = 0.018) and NRS (p = 0.006) and CCLAD in WBF (p = 0.029). There were no differences in disruptive behavior (FLACC p = 0.573), anxiety (VPTm p = 0.474), blood pressure (SBP p = 0.954; DBP p = 0.899), heart rate (p = 0.726), oxygen saturation (p = 0.477), and respiratory rate (p = 0.930) between anesthetic techniques.
Conclusion
Conventional technique resulted in less pain perception for dental local anesthesia.
Clinical relevance
Conventional technique reduces the self-reported pain in children 9–12 years old, and therefore, the use of additional devices or different anesthetic techniques is not justified.
