RESUMEN
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.

Objective: To evaluate the influence of different local anaesthetic techniques in pain, disruptive behaviour and anxiety in children´s dental treatment.Material and methods: This was a randomised and parallel clinical trial. The sample consisted of 105 children (5-8 years old) that were divided into three groups (n = 35) according to the anaesthetic technique: conventional anaesthesia (CA); vibrational anaesthesia (VBA); computer-controlled local anaesthesia delivery (CCLAD). The outcomes were self-perception of pain (Wong-Baker Faces Pain Rating Scale - WBF; Numerical Rating Scale - NRS); disruptive behaviour (Face, Legg, Activity, Cry, Consolability Scale - FLACC); anxiety (Corah's Dental Anxiety Scale; modified Venham Picture test - VPTm) and physiological parameters (blood pressure - systolic - SBP and diastolic - DBP; heart rate - HR; oxygen saturation - SpO2; respiratory rate - RR). Data were statistically analysed with Kruskall-Wallis test and ANOVA for repeated measures with Tukey post hoc test (α = 0.05).Results: All the patients exhibited the same level of dental anxiety at baseline (Corah's Dental Anxiety Scale). There was no difference in self-perception pain, irrespective the evaluation tool used (WBF - p = .864; VAS - p = .761). No differences were detected in disruptive behaviour (FLACC - p = .318); anxiety (VPTm - p = .274); blood pressure (SBP - p = .239; DBP - p = .512); heart rate (p = .728); oxygen saturation (p = .348) and respiratory rate (p = .238) between anaesthetic techniques.Conclusion: Different anaesthetic dental local techniques do not affect the levels of pain, disruptive behaviour, anxiety and physiological parameters in children aged 5-8 years old.
