Impact of online education due to the pandemic among college students: Knowledge, Attitude and Practices analysis with structural equation modeling.

Pandemic 2019 is observed in all sectors of the world which had caused a huge disruption in the education system in India as well as worldwide adding challenges to student's life. We aimed to provide an outline on E-Learning and the difficulties experienced by students of various colleges in the southern parts of India and to conduct knowledge, attitude and practices (KAP) analysis based on student's perception regarding E-learning by collecting an online survey, 346 valid questionnaires were retrieved. In order to evaluate the association between the variables of KAP, structural equation modeling was used for data analysis.

Comparison of Streptococcus mutans Adhesion on New and Recycled Metal Brackets: An In Vitro Study.

Background: Evaluation of adhesion of on recycled orthodontic brackets is significant, as is the main causative factor in enamel demineralization and many clinicians, in their practice, resort to reconditioning of brackets, as it is cost-effective. Thus, this study aimed to evaluate and compare the adhesion of on new brackets of three different companies (Group I, Group II, and Group III) and brackets recycled by three different recycling methods (RC I: flame heating followed by acid bath; RC II: flame heating followed by ultrasonic cleaning and electropolishing; RC III: flame heating followed by sandblasting and electropolishing). Materials and methods: A total of 10 brackets from each group were incubated with 10 colony-forming units (CFUs) of in trypticase soy broth overnight.
