Background: Dental anxiety is a matter of serious concern to pediatric dentists as it may impede the efficient delivery of dental care. If not adequately resolved, a persistent negative response pattern may emerge. Thaumaturgy, commonly known as magic trick, has become popular recently. It is a tool that distracts and relaxes the child by using magic trick while the dentist performs necessary treatment. Hence, the aim of this study was to evaluate the effectiveness of Thaumaturgic aid in alleviation of anxiety in 4-6 - year-old children during administration of local anesthesia using the inferior alveolar nerve block (IANB) technique. Methods: Thirty children aged between 4-6 years with dental anxiety requiring IANB were included in this study. Patients were divided equally into two groups: Group I, thaumaturgic aid group and Group II, conventional non-pharmacological group using randomization. Anxiety was measured before and after using the intervention with Raghavendra Madhuri Sujata-Pictorial scale (RMS-PS), Venham's anxiety rating scale, and pulse rate. All the data were tabulated and compared using statistical analysis. Results: Children in thaumaturgy group (Group- I) exhibited significantly lower anxiety during IANB in comparison with children in the conventional group (Group- II) and the difference was statistically significant. Conclusion: Magic tricks are effective in reducing anxiety among young children during IANB; Moreover, it expands the arsenal of behavior guidance techniques for treatment of children with anxiety and plays an important role in shaping the behavior of a child in pediatric dentistry.

Understanding the electrocatalysis OER and ORR activity of ultrathin spinel Mn3O4

Rapid depletion of non-renewable sources has made us look into possible green energy alternatives tomeet energy challenges. Electrocatalytic reactions involving oxygen evolution reaction (OER) and oxygenreduction reaction (ORR) play crucial roles in assisting the derivation of clean forms of energy. Here, wedemonstrate that few layers of the manganese oxide: hausmannitene (atomically thin two dimensional(2D-Mn3O4) can be exfoliated from its bulk form hausmannite (Mn3O4). Most significantly, the hausmanniteneexhibits catalytic activity towards oxygen reduction and evolution reactions. The hausmannitenehas enhanced Mn(III) ions (65%) compared to its parent structure hausmannite (31%). The Mn(III) ionsin a distorted lattice show the highest catalytic activity towards OER performance with the oxygen electrodeactivity (DE) of 1.08 eV for hausmannitene. The density functional theory (DFT) calculations, confirmedthe presence of both Mn(III) and Mn(II) sites on the (112)-oriented surface of Mn3O4 which arehighly active for OER and ORR, having vacant and filled orbitals of lowest and highest energy, respectively. Increased oxidation sites aiding to better performance of 2D structure was theoretically manifested. Therefore, demonstrating that similar mechanisms can be used to explore other 2D oxides aspossible efficient stable electrocatalyst substitute for energy conversion.
