RESUMO
PURPOSE: Prior studies explored factors influencing dental study choice, but shifts from BDSc to DDS degrees in some countries impact demographics and motivations, potentially affecting the dental workforce. The aim of this study was to establish Australian DDS and BOH students' sociodemographics and career motivations. METHODS: Questionnaires conducted in mid-2019 assessed sociodemographic profiles and career motivations. Statistical analysis utilized descriptive statistics and Fisher's exact test. RESULTS: The overall response rate was 71.3%. DDS students had an average age of 25.2 years, while BOH students averaged 21.5 years. Most BOH (80.7%) and DDS students (52.0%) were female. They were mainly single, local, Australian citizens from metropolitan areas. Self-motivation ranked highest, particularly for DDS students (P < 0.05). Significant motivators included healthcare occupation, helping others, interesting career, and flexible hours (P < 0.05). DDS students were more motivated by flexible hours and independence (P < 0.05), while females emphasized a healthcare profession (P = 0.003). International students were motivated by being their own boss (P = 0.003), and private school graduates valued lifestyle within the profession (P = 0.049). CONCLUSION: Despite sociodemographic changes, the main motivations for studying dentistry remain consistent. DDS students prioritized lifestyle factors such as time and remuneration over BOH students.

The present research explores linear as well as nonlinear radiation patterns based on the MHD non-Newtonian (Maxwell) nanofluid flow having Arrhenius activation energy. This study's core focus is MHD properties in non-Newtonian fluid dynamics and boundary layer phenomena analysis. It initiates with time-dependent equations, employing boundary layer approximations. Extensive numerical computations, executed with custom Compact Visual Fortran code and the EFD method, provide profound insights into non-Newtonian fluid behavior, revealing intricate force interactions and fluid patterns. To check the stability of the solution, a convergence and stability analysis is performed. With the values of ΔY = 0.25, Δτ = 0.0005, and ΔX = 0.20; it is found that the model convergence occurs to the Lewis number, Le > 0.016 as well as the Prandtl number, Pr > 0.08. In this context, investigating non-dimensional results that depend on multiple physical factors. Explanation and visual representations of the effects of different physical characteristics and their resultant temperatures, concentrations, and velocity profiles are provided. As a result of the illustrations, the skin friction coefficient and Sherwood number, which are calculated, as well as Nusselt values, have all come up in discussion. Additionally, detailed representations of isothermal lines and streamlines are implemented, and it is pointed out that the development of these features occurs at the same time as Brownian motion. Furthermore, the temperature field for Maxwell fluid is modified due to the impression of chemical reaction as well as the Dufour number (Kr and Du). Our research demonstrates the superior performance of non-Newtonian solutions, notably in cases involving activation energy and nonlinear radiation. This paradigm shift carries significant implications. In another context, the interplay between Maxwell fluid and nonlinear radiation is notably affected by activation energy, offering promising applications in fields like medicine and industry, particularly in groundbreaking cancer treatment approaches.
