https://www.selleckchem.com/products/cp2-so4.html Dental trauma is one of the critical oral health problems in childhood and adolescence that can affect an individual's quality of life. Teachers may witness a dental injury on many occasions, and they are likely to be involved at the site of an accident. Hence, they should be capable of managing prompt and correct emergency treatment at the accident site. The aim of this cross-sectional study was to assess the level of knowledge and experience of Croatian elementary and high school teachers concerning dental trauma. A questionnaire-based cross-sectional online survey was conducted to determine knowledge and experience about traumatic dental injuries among 803 full-time working elementary and high school teachers. The inclusion criteria were full-time employment at the time of data collection with at least 1year of teaching experience. Retirement (teachers aged ≥65years) and unwillingness to participate in the survey were the exclusion criteria. The Student t test or one-way ANOVA, with Tukey's post hoc wa programs are recommended.We propose a surrogate model for the fluid-structure interaction (FSI) problem for the study of blood dynamics in carotid arteries in presence of plaque. This is based on the integration of a numerical model with subject-specific data and clinical imaging. We propose to model the plaque as part of the tissues surrounding the vessel wall through the application of an elastic support boundary condition. In order to characterize the plaque and other surrounding tissues, such as the close-by jugular vein, the elastic parameters of the boundary condition were spatially differentiated and their values were estimated by minimizing the discrepancies between computed vessel displacements and reference values obtained from CINE Magnetic Resonance Imaging data. We applied the model to three subjects with a degree of stenosis greater than 70%. We found that accounting for both plaque and jugular vein in
