Comprehensive Bio-Screening of Phytochemistry and Biological Capacity of Oregano (Origanum vulgare) and Salvia triloba Extracts against Oral Cariogenic and Food-Origin Pathogenic Bacteria.

This study utilized phytochemical screening to conduct the qualitative analysis of plant extracts, aiming to identify various classes of secondary metabolites. Moreover, the antibacterial activity of different types of Oregano vulgare and Salvia triloba extracts was determined. To achieve the aim of this study, aqueous, ethanolic, and enzymatic extracts were prepared and screened for phytochemical capacity and antioxidant activities. The determination of the antibacterial activity included phenotypic screening of antibiotic susceptibility pattern of oral and food pathogenic bacterial strains, determination of the minimum inhibitory concentration and minimum bactericidal concentration-via microdilution broth test and in vitro valuation of antibacterial efficacies-of the anti-biofilm properties of the studied herbal extractions. Results: Our study evaluated the phytochemical composition and the antioxidant, antibacterial, and anti-biofilm properties of O. vulgare and S. triloba extracts. The analyzed samples contained bioactive compounds, such as phenolics and flavonoids, contributing to the observed strong antioxidant effect. Furthermore, they exhibited notable activity against oral biofilm formation and demonstrated significant antibacterial efficacy against dental caries' microorganisms as well as food pathogens. Despite methodological variations, all extracts showed significant antioxidant capacity and promising antibacterial activity against various pathogens, including resistant strains, while also inhibiting biofilm formation. Although limited to two plant species and facing methodological constraints, this study lays the groundwork for future research, indicating the therapeutic potential of O. vulgare and S. triloba extracts. Further exploration is needed to report on underlying mechanisms and validate efficacy through clinical trials.

Plant-Derived Compounds: A Promising Tool for Dental Caries Prevention.

There is a growing shift from the use of conventional pharmaceutical oral care products to the use of herbal extracts and traditional remedies in dental caries prevention. This is attributed to the potential environmental and health implications of contemporary oral products. This comprehensive review aims at the analysis of plant-derived compounds as preventive modalities in dental caries research. It focuses on data collected from 2019 until recently, trying to emphasize current trends in this topic. The research findings suggest that several plant-derived compounds, either aqueous or ethanolic, exhibit notable antibacterial effects against Streptococcus mutans and other bacteria related to dental caries, with some extracts demonstrating an efficacy comparable to that of chlorhexidine. Furthermore, in vivo studies using plant-derived compounds incorporated in food derivatives, such as lollipops, have shown promising results by significantly reducing Streptococcus mutans in high-risk caries children. In vitro studies on plant-derived compounds have revealed bactericidal and bacteriostatic activity against S. mutans, suggesting their potential use as dental caries preventive agents. Medicinal plants, plant-derived phytochemicals, essential oils, and other food compounds have exhibited promising antimicrobial activity against oral pathogens, either by their anti-adhesion activity, the inhibition of extracellular microbial enzymes, or their direct action on microbial species and acid production. However, further research is needed to assess their antimicrobial activity and to evaluate the cytotoxicity and safety profiles of these plant-derived compounds before their widespread clinical use can be recommended.

Development of a Multiplexing Injector for Gas Chromatography for the Time-Resolved Analysis of Volatile Emissions from Lithium-Ion Batteries.

Multiplex sampling, so far mainly used as a tool for S/N ratio improvement in spectroscopic applications and separation techniques, has been investigated here for its potential suitability for time-resolved monitoring where chromatograms of transient signals are recorded at intervals much shorter than the chromatographic runtime. Different designs of multiplex sample introduction were developed and utilized to analyze lithium-ion battery degradation products under normal or abuse conditions to achieve fast and efficient sample introduction. After comprehensive optimization, measurements were performed on two different GC systems, with either barrier discharge ionization detection (BID) or mass spectrometric detection (MS). Three different injector designs were examined, and modifications in the pertinent hardware components and operational conditions used. The shortest achievable sample introduction time was 50 ms with an interval of 6 s. Relative standard deviations were lower than 4% and 10% for the intra- and inter-day repeatability, respectively. The sample introduction system and column head pressure had to be carefully controlled, as this parameter most critically affects the amount of sample introduced and, thus, detector response. The newly developed sample introduction system was successfully used to monitor volatile degradation products of lithium-ion batteries and demonstrated concentration changes over the course of time of the degradation products (e.g., fluoroethane, acetaldehyde and ethane), as well as for solvents from the battery electrolyte like ethyl carbonate.

A Holistic Approach for Ethics and Sustainability in the Food Chain: The Gateway to Oral and Systemic Health.

Food production is a complex matter, affecting people's lives, organizations' profits, and the well-being of the whole planet, and has multifaceted ethical considerations surrounding its production, distribution, and consumption. This paper addresses the pressing need to confront ethical challenges within the food system, encompassing issues such as environmental sustainability, food security, and individual food choices for better oral and systemic health of all individuals around the globe. From agricultural practices to global trade and food waste, ethical implications are addressed across various domains, highlighting the interconnectedness of ethical decision-making in the food industry. Central themes explored include the ethical dimensions of food production methods, the impact of global trade on food ethics, and the role of individuals in making ethically informed food choices. Additionally, this paper considers the spiritual and physical significance of food, particularly through the lens of oral health as a gateway to holistic well-being. Recognizing the complexity of the food and mouth ecosystem, this paper calls for serious interventions in legislation and economics to promote ethical protocols and techniques for sustainability reasons. It emphasizes the importance of ethical considerations in food safety management systems, regulatory frameworks, and quality standards. Moreover, this paper underlines the need for a comprehensive approach to address ethical dilemmas and moral values inherent in the food industry and oral health policies, adopting the precautionary principle and ethical decision-making frameworks. This article finally aims to serve as a call to action for stakeholders across the food industry and the healthcare sector, to prioritize ethical practices, promote transparency, rearrange economic parameters, and work towards a more sustainable and equitable food system for inner and outer oral and systemic health and human sustainability for all.

Educational Approach: Application of SWOT Analysis for Assessing Entrepreneurial Goals in Senior Dental Students.

The SWOT (strengths, weaknesses, opportunities, and threats) analysis is a framework used to evaluate a company's competitive position and to develop strategic planning. In the competitive dental sector, it can aid dentists in identifying and analyzing internal strengths and weaknesses, as well as external opportunities and threats. This study focuses on senior dental students of the Department of Dentistry at the National and Kapodistrian University of Athens, Greece, aiming to scrutinize their use of SWOT analysis and assess its application as a tool for evaluating entrepreneurial goals and making career decisions in dental entrepreneurship. The research sample comprises 116 senior dental students (N1) in the final undergraduate year of their dental education, with data collection accomplished through the administration of an e-questionnaire during the obligatory course of "Organization and management of dental practices" in December 2023. The data extracted from the SWOT analysis encompass internal and external factors, gender distinctions, and outcomes derived from Stepwise Binary Logistic Regression concerning predictor markers. The results from the SWOT analysis of 114 valid questionnaires (N2), revealed that participants identified communication skills (50%) and organization skills (49.10%) as their primary strengths, followed by favorable personal traits contributing to goal success (36%). Weaknesses predominantly centered around emotional and personal traits like anxiety (41.20%) and other characteristics, alongside practical challenges such as lack of initial capital (24.60%). Main opportunities included collaboration with experienced dentists (33.30%) and access to training programs (27.20%), while economic instability in Greece (77.20%) and the saturated dentist profession (26.30%) were perceived as significant threats. Gender differences were notable, with female dentists more likely to report organization skills as a strength and anxiety as a weakness. Values such as industriousness, persistence, and ethics were commonly shared, with actions focusing on training programs (57.9%) and gaining experience with experienced dentists (29.8%). Cluster analysis identified two subgroups, with one emphasizing utilizing all available options (n = 49) and the other prioritizing on gaining professional skills and experience (n = 65). Logistic regression indicated that participants valuing industriousness were less likely to explore all available options, while those recognizing personal traits were more likely to do so. The study's outcomes highlight key predictor factors linked to a proactive orientation in career decision-making among senior dental students. These insights offer valuable implications for educational institutions and career counselors.

Orthodontic Risk Perspectives among Orthodontists during Treatment: A Descriptive Pilot Study in Greece and Slovakia.

This study explores orthodontists' perspectives on risks associated with orthodontic treatment, as described by Greek and Slovak orthodontists. Informed by the foundational importance of effective communication of risk perspectives in health sciences, particularly in facilitating valid consent and shared decision-making, this research addresses gaps identified in the literature concerning the consistent communication of potential treatment risks based on demographic and cultural characteristics. This study identifies 15 potential critical risks during orthodontic treatment. These risks include root resorption; temporary undesired changes to the occlusion; sleep difficulties; not achieving an ideal result; development of black triangles between teeth; taking additional X-rays; speech difficulties; using a protective splint during sports; duration of treatment; number of visits; transmission of infectious diseases; and swallowing orthodontic appliances. A questionnaire, distributed electronically to orthodontists in Greece (N1 = 570) and Slovakia (N2 = 210) from September 2022 to December 2022, aimed to assess risk communication practices, taking into consideration socio-demographic factors, such as country, gender, age, and academic-degree-related variations. A total of 168 valid questionnaires (91 from Slovakia and 77 from Greece) were obtained, indicating significant disparities in the risks emphasized and preferred forms of consent. The Greek orthodontists focused more on the risks involved, such as relapse, root resorption, temporal occlusal changes, and failure of desired movement, while the Slovak practitioners tended to be more interested in sleeping difficulties, temporal occlusal changes, and not achieving an ideal result. They also obtained written or digital consent from patients or their parents/guardians more frequently than the Greek team. Male orthodontists discussed specific risks more frequently, including relapse and extractions, whereas females preferred written or digital consent. PhD-trained orthodontists prioritized certain risks, indicating the need for tailored approaches. This study underscores the dynamic nature of risk assessment in orthodontic practice, emphasizing its ethical and strategic dimensions. The findings advocate for tailored risk communication strategies that recognize individual, contextual, and cultural factors, and the need for an orthodontic informed consent protocol for a tailored communication approach for patients to elevate the standard of care in European orthodontics. The reliance on digital tools reflects contemporary trends in enhancing patient understanding, thereby supporting ongoing innovation in orthodontic practices.

An Update on Drug-Nutrient Interactions and Dental Decay in Older Adults.

In recent decades, the global demographic landscape has undergone a discernible shift that has been characterised by a progressive increase in the proportion of elderly individuals, indicative of an enduring global inclination toward extended lifespans. The aging process, accompanied by physiological changes and dietary patterns, contributes to detrimental deviations in micronutrient consumption. This vulnerable aging population faces heightened risks, including dental caries, due to structural and functional modifications resulting from insufficient nutritional sustenance. Factors such as physiological changes, inadequate nutrition, and the prevalence of multiple chronic pathologies leading to polypharmacy contribute to the challenge of maintaining an optimal nutritional status. This scenario increases the likelihood of drug interactions, both between medications and with nutrients and the microbiome, triggering complications such as dental decay and other pathologies. Since the drug industry is evolving and new types of food, supplements, and nutrients are being designed, there is a need for further research on the mechanisms by which drugs interfere with certain nutrients that affect homeostasis, exemplified by the prevalence of caries in the mouths of older adults. Infectious diseases, among them dental caries, exert serious impacts on the health and overall quality of life of the elderly demographic. This comprehensive review endeavours to elucidate the intricate interplay among drugs, nutrients, the microbiome, and the oral cavity environment, with the overarching objective of mitigating the potential hazards posed to both the general health and dental well-being of older adults. By scrutinising and optimising these multifaceted interactions, this examination aims to proactively minimise the susceptibility of the elderly population to a spectrum of health-related issues and the consequences associated with dental decay.

Quality of Life and Wellbeing Parameters of Academic Dental and Nursing Personnel vs. Quality of Services.

Quality of life (QOL) is based on one's perception of one's position in life with respect to one's goals, expectations, standards, and concerns. It is also influenced by one's culture and value system, workflow, and workplace situation; in turn, QOL influences the quality of service one is able to provide. In this study, we aim to report on dental and nursing academics' QOL and wellbeing at the end of the third year of the COVID-19 pandemic. There are several studies on the impact of the COVID-19 pandemic on health professionals (nurses and dentists), but it is important to investigate their quality of life three years later; furthermore, knowledge about academic staff is very limited. The World Health Organization Quality of Life-BREF Scale (WHOQOL-BREF) tool, recording the physical, psychological, social, and environmental dimensions of QOL, was used. The WHOQOL-BREF was modified using a spiritual coaching/mentoring approach in a two-step design and validation procedure. The modified SHQOL-BREF (Spiritual Healthcare version) designed for this study was uploaded and filled in online during April-June 2023. The staff (N = 120, 75% female) of the Departments of Dentistry (44.2%) and Nursing (55.8%) of the National and Kapodistrian University of Athens participated anonymously. QOL in terms of physical health was reported at a higher level (M = 72.2 points) compared to social relationships (M = 69 points), psychological health (M = 65 points), and environment (M = 59 points) (scores reported on a 0-100 scale). Overall, QOL was rated at 66 points, while satisfaction with one's health was at 72 points. Job satisfaction (M1 = 3.2) and spirituality (M2 = 3.0) were reported at a medium level on a five-point scale, while personal beliefs and values were reported at a high level (M3 = 4.0). The four areas of QOL are associated with job satisfaction, personal beliefs, and spirituality. Participant age presented a significant moderate-strong effect on physical health (F (3.97) = 2.89, p < 0.05, η2p = 0.08) and on the environment (F (3.97) = 2.80, p < 0.05, η2p = 0.08), and marital status had a significant effect on social relationships (F (1.97) = 9.66, p < 0.05, η2p = 0.09). Married participants reported consistently higher levels of QOL compared to single participants, for all age groups. The department had a significant moderate effect on social relationships (F (1.97) = 5.10, p < 0.05, η2p = 0.05), and education had a significant moderate-strong effect on psychological health (F (2.97) = 3.74, p < 0.05, η2p = 0.07). PhD-level participants in both departments presented higher levels of psychological health compared to those with lower educational levels. Also, participants from the Department of Dentistry reported higher levels of social relationship QOL in all educational groups compared to the Department of Nursing. Overall, according to our findings, PhD participants generally had better psychological health. Those under 40 years of age had higher levels of physical health and environmental quality of life, while married participants and those from the Department of Dentistry had higher levels of social interactions than those from the Department of Nursing. Strategic planning on sustainability and QOL initiatives should be introduced after the COVID-19 pandemic for dental and nursing academic personnel to promote resilience and QOL scores. Enhancing the QOL of academic staff is essential for developing health promotion activities at universities and can help boost performance among staff and students.

Ethical Dilemmas for Dental Students in Greece.

Professional dental ethics for students are based on promoting oral health for dental patients and reinforcing an anthropocentric approach to communication and dental services. A total of 133 dental students (males 33.8% N1 = 46, females 66.2% N2 = 87) completed the study questionnaire. Descriptive statistics were applied, and non-parametric Kruskal-Wallis tests were used (p < 0.05). Students refuse services to patients that misbehave (37.6%), have irrational demands (18%), and when clinical cases exceed their capabilities (36.8%). Of the participants, 50.4% want to waive confidentiality when abuse is declared. Ethical role models are educators (33.8%), other qualified dentists (25.6%), and their parents (21.8%). Female gender positively affects integrity (p = 0.046), altruism (p = 0.032), and difficulty in conversations among colleagues (p = 0.036). Students outside the capital are less interested in esthetic issues (p = 0.007), in giving more than one treatment plan (p = 0.006), and in being confronted with inadequate treatments from other colleagues (p = 0.005). Family income positively affects clinical skills (p = 0.003), trust issues (p = 0.008), and moral insight and intuition (p = 0.02). Presentation with clinical scenarios is the preferred educational method (49.6%). Dental students show compassion for poor patients, respect patients' autonomy, and guide patients to choose the best treatment plan before receiving dental ethics seminars. There is a positive relationship between the ethical footprints of students and gender, origin, family income, postgraduate studies, and future professional plans. Factors and ways to incorporate ethics in the dental curriculum could be considered when planning relevant courses.

Bi-functional photocatalytic heterostructures combining titania thin films with carbon quantum dots (C-QDs/TiO2) for effective elimination of water pollutants.

In this study, carbon quantum dots (C-QDs), prepared via hydrothermal-microwave procedures, were successfully combined with nanostructured titania (TiO2). The photocatalytic oxidation/reduction activity of the C-QDs/TiO2 composite films was evaluated in the decomposition of organic-inorganic contaminants from aqueous solutions under UV illumination. Physicochemical characterizations were applied to investigate the crystal structure of the carbon quantum dots and the composites. It was found that the prepared C-QDs/TiO2 composites had great contribution to the photocatalytic reduction of hexavalent chromium (Cr+6) species and 4-Nitrophenol (PNP) as well as to the photocatalytic oxidation of methylene blue (MB) and Rhodamine B (RhB) dyes. The mechanism of the photocatalytic reaction was studied with trapping experiments, revealing that the electron (e-) radical species were powerfully supported for the photocatalytic reduction of Cr+6 and PNP and the holes (h+) are the main active species for the photocatalytic oxidation reactions.

Economic Valuation of Balkan Chamois Conservation.

The Balkan chamois (Rupicapra rupicapra balcanica) is a caprine of the rocky mountain slopes, threatened in Greece by illegal hunting and population isolation. We used a contingent valuation method to assess the willingness to pay (WTP) for chamois conservation of 500 residents of the region of Eastern Macedonia and Thrace. Most of the participants (61.6%) were WTP a mean of EUR 41.6 for chamois conservation, totaling EUR 6.03 million for the target population. Attitudes toward and knowledge about chamois, moralistic worldviews (spiritual reverence and ethical concern for nature and wildlife), participation in wildlife-related consumptive outdoor activities (i.e., hunting and fishing), intention to participate in conservation actions for the species, and encounters with the species in the wild were positively associated with WTP for its conservation. Dominionistic worldviews (humans have mastery, physical control, and dominance of wildlife) were negatively associated with WTP, while highly educated females with high income were more WTP for implementing relevant conservation actions. Factors involving previous knowledge of the chamois positively influenced the WTP, thus, confirming the construct's bias toward charismatic species. The findings show that Greek residents highly value the chamois and its conservation and would be useful for advising this process and achieving its conservation management.

Awareness of Students and Dentists on Sustainability Issues, Safety of Use and Disposal of Dental Amalgam.

Among the pillars of sustainability in health care units is environmental protection. Although an EU-wide dental amalgam phase-out legislation exists, quantities of this material are still to be found in the market, dental offices or in the mouths of patients. The purpose of this study is to record the views of dentists and dental students in Greece regarding the use and safety of dental amalgam for people and the environment as well as their attitudes towards its restriction and disposal. MATERIALS AND METHODS: Two different questionnaires, through Google forms, were filled by each group. Descriptive statistics were used to describe the variables. The chi-square test or the chi-square test with Yates correction was used to examine potential differences per group (p-value = 0.05). Overall, 564 people participated in this study; 462 (81.9%) dentists (N1) and 102 (18.1%) dental students (N2). RESULTS: Both groups agreed that they no longer use dental amalgam often. Dentists (39.8%) and students (36.4%) consider amalgam to have a moderate burden on the environment. This answer differed significantly per year of profession and year of undergraduate studies, respectively, with dentists from 6-25 years in the profession and 4th-year students, being the least aware on the environmental footprint of dental amalgam. Further, professionals (70%) and students (60%) believe that dental amalgam has a hazardous impact on patient's health, at all or to a small extent. For staff health, dentists reported at a moderate degree dangerous impact (32.9%) while students (36.4%), respectively. The impact on patients and staff health, were found to differ significantly per region of practicing dentistry for both groups. Finally, there were suggestions made from both groups about the necessity of information sharing on amalgam and mercury safety and the impact on the environment at the level of professional organizations. CONCLUSIONS: Students, younger dentists and those living in non-urban regions seem to be more sensitive to the environmental impact of amalgam use, disposal, and health of people. Environmental issues should be addressed thoroughly by professional organizations, enhancing relevant activities for all people involved.

The In Vitro Assessment of Antibacterial and Antioxidant Efficacy in Rosa damascena and Hypericum perforatum Extracts against Pathogenic Strains in the Interplay of Dental Caries, Oral Health, and Food Microbiota.

The rising demand for novel antibiotic agents prompts an investigation into natural resources, notably plant-derived compounds. In this study, various extracts (aqueous, ethanolic, aqueous-ethanolic, and enzymatic) of Rosa damascena and Hypericum perforatum were systematically evaluated against bacterial strains isolated from dental lesions (n = 6) and food sources (raw milk and broiler carcass, n = 2). Minimal inhibitory concentration (MIC), minimal bactericidal concentration (MBC), antibiofilm activity, and time-kill kinetics were assessed across a range of extract concentrations, revealing a dose-responsive effect. Notably, some extracts exhibited superior antibacterial efficacy compared to standard clinical antibiotics, and the time-kill kinetics demonstrated a rapid elimination of bacterial loads within 24 h. The susceptibility pattern proved strain-specific, contingent upon the extract type, yet all tested pathogens exhibited sensitivity. The identified extracts, rich in phenolic and polyphenolic compounds, as well as other antioxidant properties, contributed to their remarkable antibiotic effects. This comprehensive investigation not only highlights the potential of Rosa damascena and Hypericum perforatum extracts as potent antibacterial agents against diverse bacterial strains including caries pathogens, but also underscores their rapid action and dose-dependent efficacy. The findings suggest a promising avenue for harnessing plant-derived compounds in the development of novel antimicrobial strategies against dental caries and other oral inflammations, bridging the gap between natural resources and antibiotic discovery.

The Effect of Sound in the Dental Office: Practices and Recommendations for Quality Assurance-A Narrative Review.

Sound is inextricably linked to the human senses and is therefore directly related to the general health of the individual. The aim of the present study is to collect data on the effect of two dimensions of sound, music, and noise from an emotional and functional point of view in the dental office and to perform a thorough review of the relevant literature. We collected articles from the databases PubMed and Google Scholar through keywords that were related to noise and music in healthcare. Important information was also extracted from articles on the web and official websites. Screening of the relevant literature was performed according to accuracy and reliability of the methodology tested. A total of 261 articles were associated to sound and music in healthcare. Ninety-six of them were the most well documented and were thus included in our article. Most of the articles associate noise with negative emotions and a negative impact on performance, while music is associated with positive emotions ranging from emotional state to therapeutic approaches. Few results were found regarding ways to reduce noise in a health facility. If there is a difficulty to find effective methods of reducing the daily noise-inducing sounds in the dental office, we must focus on ways to incorporate music into it as a means of relaxation and therapy.

Leadership and Managerial Skills in Dentistry: Characteristics and Challenges Based on a Preliminary Case Study.

Dentistry is changing rapidly in a dynamic and challenging mode and is incorporating digital technology, communication, and managerial skills for profitable enterprises. On the new dental horizon, the profession requires engaging and inspiring role models and leaders. Ιdentifying and developing human soft skills can improve quality issues and guarantee a sustainable dental business. The concept of leadership is a very complex and multidimensional phenomenon as observed from the current literature. In different commercial environments, there has been a huge discussion on the specific characteristics of an effective leader. In dentistry, the subject needs further investigation. This article aims to bring up the importance of dental leadership and highlights the need of identifying dental leaders committed to excellency. It also challenges the need for educational shift on dental leadership management. Finally, it aims to support and develop educational transformations based on positive preliminary data observed by incorporating a new, relevant subject in the dental curriculum.

Quality of Life and Satisfaction from Career and Work-Life Integration of Greek Dentists before and during the COVID-19 Pandemic.

Quality of life (QoL) of dental professionals is a basic parameter of the quality of dental services (QS), a fact well-documented before and during the COVID-19 pandemic in different countries. This study is a comprehensive, cross-sectional survey aimed to explore possible differences in satisfaction from career and work-life integration, as well as QoL in a sample of Greek dentists during the second lockdown in March 2021. Methods: 804 dentists from the vast metropolitan area of Athens and Piraeus selectively responded by completing a self-reported questionnaire based on: the Copenhagen Questionnaire (CQ) for assessing work stress; the Maslach Burnout Inventory-Human Service Survey (MBI-HSS) for evaluating personal accomplishment; and the Quality-of-Life work scale (ProQOL-CSF). Data were analyzed using the independent t-test, ANOVA, Pearson's correlation, and multiple linear regression. Results: QoL and career satisfaction were significantly diminished during the pandemic. Career satisfaction despite the pandemic was overall influenced in tandem by age (b = 0.427, p = 0.001), marital status (b = 0.276, p = 0.021), and inversely by years of practice (b = -0.330, p = 0.007) and income (b = -0.221, p = 0.015). Satisfaction from the work-life integration was influenced before the pandemic by marital status (b = 0.255 p = 0.013), years of practice (b = -0.371, p = 0.0001), while gender, years of practice, age, higher education, and income played a significant role during the pandemic. QoL was impacted before pandemic by age (b = -1.007, p = 0.001), number of children (b = -1.704, p = 0.018), and higher degree (b = -1.143, p = 0.001), while during the pandemic by gender (b = -0.582, p = 0.002), number of children (b = 0.469, p = 0.037), higher degree (b = 0.279, p = 0.009), and years of practice (b = -0.523, p = 0.0001). Males were more prone to low QoL, and dissatisfaction with career and work-life integration, during the pandemic. Income is a predictor of career satisfaction despite the pandemic. Personal resources through deep human relationships, higher education, beliefs, and values can offer a resilience shield against professional difficulties in periods of unexpected stressful events.

Sustainable Distance Online Educational Process for Dental Students during COVID-19 Pandemic.

In this study, we evaluated the perception of distance online learning in undergraduate dental students in two different European countries during the second lockdown of the COVID-19 pandemic to explore sustainable undergraduate educational and examination e-learning forms. Dental students from Dental school of Athens, National and Kapodistrian university of Athens (N1_3rd preclinical year = 131, N2_4th clinical year = 119) and Dental school of Copenhagen (3rd preclinical year N3 = 85) completed the mixed-designed Dental e-Learning process Questionnaire (DeLQ) distributed in a google form. Responses to closed-ended questions were collected on a five-point Likert scale. Descriptive statistics were applied, and non-parametric Kruskal-Wallis tests were used to examine student groups. N1 (90% strongly agree) students reported that "e-learning is a suitable education method for theory in dentistry" at a significant level and more often than N2 (43% strongly disagree). N1 and N2 students strongly agreed that they preferred face-to-face teaching rather than distance e-learning. A relatively low number of N1 (31%) students believed that e-learning prepares them sufficiently for their practical training while none of the (0%) N2 cohort agreed. A low percentage of students in both years (N1 = 31%, N2 = 23%) believed that e-learning prepared them for their exams. Additionally, N1 = 60% and N2 = 66% preferred hybrid learning. Only 26% (N1) and 19.5% (N2) desired e-learning to continue after the COVID-19 pandemic. Nearly half of the participants believed the online exam model to be unreliable (N1 = 49%, N2 = 43%). Overall, students considered distance e-learning as an educational method applicable only to theoretical lessons. However, the lack of physical communication and interaction in distance learning led students to prefer a blended method. Students of the two faculties seemed to agree on many points, but there were also specific differences attributable to the differences in the programs and educational culture of the two countries.

Estimation of Factors Affecting Burnout in Greek Dentists before and during the COVID-19 Pandemic.

This study is a comprehensive, cross-sectional survey in occupational burnout, career satisfaction, and quality of life conducted in March 2021 among dentists in the vast area of metropolitan Athens, Greece. Data were collected using a self-reported questionnaire based on the Copenhagen Questionnaire (CQ) for assessing work stress and the Maslach Burnout Inventory-Human Service Survey (MBI-HSS) for evaluating occupational burnout. Using the independent t-test, ANOVA, Pearson's correlation, and multiple linear regression, 804 valid questionnaires were analyzed. During the pandemic, personal exhaustion was affected by gender (b = 1.862, p = 0.0001), age (b = -0.598, p = 0.0001), number of children (b = -0.886, p = 0.020) and higher degree (b = -0.450, p = 0.012). Exhaustion due to working with patients was affected by gender (b = 0.662 p = 0.0001), age (b = -0.513, p = 0.0001), number of children (b = -0.701, p = 0.0001), higher degree (b = -0.207, p = 0.028) and years in practice (b = 0.408 p = 0.0001). Males were more prone to unhappiness, dissatisfaction, and professional physical and emotional exhaustion, but personal resources through higher education, beliefs, values, and hobbies can offer a preventive shield to all dental professionals. Economic management issues can also enhance dentists' satisfaction and feeling of safety in a rapidly changing environment.

Intention of Collaboration among Dental Students during the COVID-19 Pandemic.

Interpersonal communication skills (ICS) are crucial for effective dental practice and interprofessional collaboration. The current study aimed to assess the attitudes of Greek dental undergraduate students towards team working and their cooperation abilities during the COVID-19 pandemic. One-hundred and twenty-seven fourth-semester dental students (N1 = 127) out of 145 (N0) filled in the online survey placed on Google forms. The "Dental Students Cooperation Questionnaire" (DSC) consisted of 49 questions and was available for completion for one week during April 2020. Bivariate (ANOVA) and linear regression analysis of data revealed that mean scores of the questionnaire increased as the parents' educational level also increased. Data analysis showed that dental students had the required ICS and the intention to collaborate with each other. Many participants managed to achieve group goals, were willing to support other members to fulfill the project's goals, and there was no competition among them. They acknowledged the importance of feedback, the reward at the end of a group project and social media as a tool for teamworking communication. The students reported that the most important characteristics of an academic teacher were patience, willingness to cooperate, friendliness, politeness, willingness to help, accessibility and availability. It is suggested that group work should be included in the curriculum of dental schools to enhance the integration and evolution of students' ICS, and the DSC questionnaire can be an effective tool to assess these skills.
