Abstract

Background/Purpose: The COVID‐19 pandemic affects social and psychological resources. Healthcare workers, especially dental personnel, are more at risk for mental issues due to anxiety, pressure, and frustration. This study assessed mental health outcomes during the COVID‐19 epidemic among Iranian dental care providers, focusing on insomnia, anxiety, depression, and posttraumatic stress disorder (PTSD). Methods: In this multicenter cross‐sectional survey, the Insomnia Severity Index, the Hospital Anxiety and Depression Scale, and the Global Psychotrauma Screening were masured. Six hundred thirty‐eight dental care providers (dental specialists, general dentists, dental hygienists, dental assistants, and dental students) from different parts of Iran (Tehran, Shiraz, Tabriz, and Mashhad) were investigated by the stratified sampling method. The univariate analysis was incorporated as independent in binary logistic regression models to analyze the data. In this study, the significance level was set at 0.05. Results: Among all the participants, 42.8% were dental students or residents, 21.9% were general or specialist dentists, 18.7% were dental assistants, and 16.6% were nonclinicians. The prevalence of insomnia, anxiety, and depression was 31.3%, 40.8%, and 54.9%, respectively. The frequency of participants in the low, moderate, and high levels of PTSD resulting from LCA 56.6%, 33.7%, and 9.7%, respectively. Conclusions: This study found a significant frequency of mental health issues among Iranian dentists. Females, participants whose relatives have COVID‐19, and those with a higher workload were more likely to develop mental health symptoms. As mental problems among dental professionals might affect the quality of patient care, diagnostic, supportive, and therapeutic interventions should be taken. [ABSTRACT FROM AUTHOR]

278. On the sparse multiscale representation of 2‐D Burgers equations by an efficient algorithm based on multiwavelets.

Abstract

In this work, we design, analyze, and test the multiwavelets Galerkin method to solve the two‐dimensional Burgers equation. Using Crank–Nicolson scheme, time is discretized and a PDE is obtained for each time step. We use the multiwavelets Galerkin method for solving these PDEs. Multiwavelets Galerkin method reduces these PDEs to sparse systems of algebraic equations. The cost of this method is proportional to the number of nonzero coefficients at each time step. The results illustrate, by selecting the appropriate threshold while the number of nonzero coefficients reduces, the error will not be less than a certain amount. The L2 stability and convergence of the scheme have been investigated by the energy method. Illustrative examples are provided to verify the efficiency and applicability of the proposed method.
