RESUMO
BACKGROUND: Dentists are the common preys for the transmission of pandemic disease because of the airborne spread via routine dental checkups. This study which is a cross-sectional one gives the idea about awareness and alertness of dentists about COVID-19 in Kerala, India. MATERIALS AND METHODS: The survey comprised 25 closed-ended questions. The survey was separated into two sections. The initial segment of the poll was identified with the socio-segment qualities that were researched, while the subsequent part was worried about dental practitioners' perspectives toward the management of COVID-19 and the apparent danger of defilement in dental facilities. RESULTS: Coronavirus management in dental clinics differs regarding adherence to the rules. An aggregate of 750 respondents finished the form, out of which 686 (91.46%) complete reactions were incorporated. The majority of the respondents concurred on inquiries regarding the knowledge, practice, and mentality of dental specialists toward the COVID-19 pandemic. CONCLUSION: The feedback of most dental specialists with respect to the readiness and view of disease control measures against the COVID-19 pandemic was positive. Dental facilities need to adhere more to the central and state government suggestions in alertness of their facilities or by tutoring their dental specialists and staff.
RESUMO
Three dimensional flower-like NiO-thermally reduced Graphene Oxide (trGO) nanocomposite was prepared by a simple hydrothermal method. The morphology and structure of the nanocomposite was characterized using Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Energy Dispersive X-ray (EDX), X-ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy. The electrocatalytic oxidation of Dopamine, Ascorbic Acid (AA) and Uric Acid (UA) was investigated using Cyclic Voltammetry (CV). The modified electrode NiO-trGO/GCE showed good electrocatalytic activity compared to bare GCE. The detection of dopamine was carried out using Differential Pulse Voltammetry (DPV) wherefrom the Limit of Detection (LOD) and linear range was estimated to be 50 nM and 10 µM to 500 µM respectively. The selective detection of dopamine in presence of UA and AA was carried out. The NiO-trGO/GCE showed excellent selectivity for the detection of dopamine in presence of UA. However AA was found to interfere in the determination of dopamine. Also, the validity of the present sensor was examined in human biological samples.
