Purpose: To evaluate and compare the efficacy of the hands-eyes-mouth distraction technique (HEM-DT) in reducing anxiety and pain levels and improving the behaviour of pre-school children during inferior alveolar nerve block (IANB) administration to that of the covering patient's vision technique (CPV-T). Methods: This study included 52 children aged 3-5 years old with primary dentition, no history of receiving local anaesthesia, and whose treatments required an IANB. These children were randomly assigned into two groups: HEM-DT (G1; n = 26) and CPV-T (G2; n = 26). Anxiety and pain levels were assessed using the Facial Image Scale and the Wong-Baker Scale, respectively, while the patient's behaviour was evaluated using the Frankl Behaviour Scale. This study was divided into two sessions including the treatment session (administration of IANB) and the control session (7 days after anaesthesia). Chi-square test, the Mann-Whitney U test and Wilcoxon test were used for statistical analyses. Results: The patients' anxiety levels did not increase 7 days after IANB in G1 (p value = 0.798); however, higher anxiety levels were observed in the G2 group (p value = 0.039). No significant differences in pain levels and behaviour were observed between the groups during administration of anaesthesia (p value > 0.005). Conclusion: HEM-DT and CPV-T showed efficacy in terms of pain and behaviour during IANB administration. Pre-school children in the HEM-DT group exhibited lower anxiety levels in the control session.
