Coping strategies, resilience and quality of life: reaction to the COVID-19 pandemic among Romanian physicians.

BACKGROUND: The COVID-19 pandemic has presented multiple psychological challenges for healthcare workers, such as anxiety, depression, burnout, and substance use disorders. In this research, we investigate the different ways Romanian physicians dealt with the difficult period of the COVID-19 pandemic. We also analyze how positive and negative stress-reducing strategies, as well as demographic variables, affect their psychological resilience and quality of life. Our goal is to provide a comprehensive overview of how physicians coped with the unprecedented global health challenges. METHODS: We carried out a national cross-sectional study of 265 physicians in Romania between January 2021 and January 2022 using a web-based questionnaire. The study employed a web-based questionnaire to assess coping mechanisms using the COPE inventory, resilience through the Connor-Davidson Resilience Scale 25 (CD-RISC 25), and quality of life via the WHOQOL-BREF scale. The COPE inventory, consisting of 60 items across 15 subscales, categorizes coping strategies into problem-focused, emotion-focused, and dysfunctional types, with each item rated on a 4-point scale. The CD-RISC 25 measures resilience on a 5-point Likert scale, with total scores ranging from 0 to 100. WHOQOL-BREF assesses quality of life through 26 items in 4 domains: physical, mental, social relations, and environmental, scored from 1 to 5 and converted to a 0-100 scale for domain scores. Univariate and multivariate linear regression models were employed to discern the intricate relationships between coping strategies, resilience levels, quality of life dimensions, and pertinent demographic factors. RESULTS: The average CD-RISC score among participants was 66.2. The mean scores for the values for the QOL subscales were 64.0 for physical well-being, 61.7 for psychological well-being, 61.2 for social relationships, and 64.7 for environment. Individuals tend to use problem-focused and emotion-focused coping more than dysfunctional mechanisms, according to the COPE inventory. Problem-focused and emotion-focused coping are positively correlated with resilience, while dysfunctional coping is negatively correlated. Resilience is significantly influenced by gender and professional status, with males and senior specialists reporting higher levels while younger physicians and residents reporting lower levels. CONCLUSIONS: Our data points to specific protective characteristics and some detrimental factors on physicians' resilience and quality of life during the pandemic.

Romanian dental students' learning experience related to lifestyle changes imposed by Covid-19 lockdown.

Background and aim: The SARS-CoV-2 outbreak in Romania was followed by the declaration of an Emergency State and the subsequent lockdown. As all the schools and universities ceased onsite activities, the teaching process continued exclusively online, on different platforms, such as Microsoft Teams or Zoom. Objectives: The aim of this cross-sectional study is to evaluate how the lifestyle changes imposed by the Covid-19 lockdown and online lectures influenced the learning experience of Romanian dental students, as their point of view could bring new information which might contribute to improving the teaching process. Methods: The questionnaire had 28 items, each with either a Likert Scale or a multiple-choice option and was distributed in April 2020, one month after implementation of circulation restrictions and social distancing. Results: Compared to classical teaching, we found that the online teaching process had a lower efficiency, with a higher satisfaction level for online courses, but lower for online practical teaching activities. The absence of human interaction was found to be detrimental to the teaching process. Conclusion: Despite the lower efficiency of online learning, it was a good alternative that helped students continue their education in the situation created by the outbreak of Covid-19. For higher learning efficiency, a compromise method consisting of online courses and onsite practical training could be a better alternative.

Comparative microleakage outcomes of different techniques used for creating the occlusal anatomy in occlusal direct restorations using the dental operating microscope.

OBJECTIVES: Microleakage in direct dental restorations is a primary causal factor in the restoration's failure. The aim of this study was to evaluate whether the technique for occlusal layering of the composite resin (the use of brush adaptation, the use of magnification, cusp build-up, stamp technique) has any effect on microleakage of direct restorations in occlusal cavities. MATERIALS AND METHODS: One hundred extracted human molars were restored using five restoration techniques (Packable Bulk technique, Occlusal Stamp technique, Successive Cusp Build-up technique, Successive Cusp Build-up technique + Brush adaptation, Successive Cusp Build-up technique + brush adaptation + Dental Operative Microscope magnification). The teeth were subjected to thermal aging for 800 cycles at 5°C and 55°C, infiltrated with basic fuchsin dye for 24 h, and then sectioned buccolingually in the middle of the crown. Infiltration was measured in four areas of the tooth section by five different observers and then given a score from 1 to 3, proportional to infiltration depth. RESULTS: The lowest mean scores for infiltration (meaning less infiltration observed) were present in Group A (1.41 ± 0.878) and Group C (1.46 ± 0.679), while Group D showed the highest infiltration scores (1.75 ± 0.853). When comparing the groups for differences, no statistically significant difference in infiltration was found between any technique p < .586. CONCLUSION: The techniques examined for placing the occlusal layer of composite in direct restorations do not differ significantly in terms of marginal infiltration, although a slight improvement was found when using the bulk technique and the successive cusp build-up.

Comparative analysis of preclinical dental students' working postures using dental loupes and dental operating microscope.

BACKGROUND: Dentists are susceptible to musculoskeletal disorders due to prolonged static postures during dental treatments. Using a magnification tool like dental operating microscope (DOM) or the dental loupes may correct the operator's posture. Up until now, few studies have focused on preclinical dental students' posture when working with the DOM, while most of them have focused on the loupes. The aim of this study was to comparatively analyse the working posture of preclinical students during a dental restoration procedure, working with two different magnification methods. MATERIALS AND METHODS: This study used a randomised cross-over design in which seventeen third year students were randomly divided into three groups. The exclusion criteria were previous contact with magnification systems and previous clinical working experience. Each student prepared 3 Black class 1 cavities on artificial lower molars: first with no magnification, following dental loupes and DOM. They were video-recorded throughout the preparation. Trunk, neck and upper-arm position were evaluated using the Posture Assessment Instrument. Students completed a questionnaire on their subjective perception of the two magnification systems. RESULTS: The statistical analysis showed significant improvement of the working posture using magnification systems compared to direct vision. The biggest improvement was obtained through the use of DOM, followed by the dental loupes. Students perceived dental loupes as being the most comfortable and easy to adapt to. They reported being more focused when using DOM. CONCLUSIONS: Both magnification systems had a positive impact on the working posture, DOM having the best results. Loupes showed better adaptability while DOM showed better concentration.
