The influence of distinct techniques of local dental anesthesia in 9- to 12-year-old children: randomized clinical trial on pain and anxiety.

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)).

Evaluation of pain, disruptive behaviour and anxiety in children aging 5-8 years old undergoing different modalities of local anaesthetic injection for dental treatment: a randomised clinical trial.

To evaluate the influence of different local anaesthetic techniques in pain, disruptive behaviour and anxiety in children´s dental treatment. This was a randomised and parallel clinical trial. The sample consisted of 105 children (5-8 years old) that were divided into three groups ( = 35) according to the anaesthetic technique: conventional anaesthesia (CA); vibrational anaesthesia (VBA); computer-controlled local anaesthesia delivery (CCLAD).
