This study aimed to assess COVID-19 perceived risk, confidence and its impact on potentially infected patients’ management practices, in a clinical dental education setting. The survey was conducted by application of a self-administered questionnaire amid the COVID-19 pandemic. Results indicate high COVID-19 perceived risk and confidence levels (86.7% and 72.8%, respectively). A significantly lower risk perception was identified for individuals classifying COVID-19 as a moderately dangerous disease and confidence was significantly lower for women and for individuals not previously exposed to confirmed or suspected cases of COVID-19. No factor-related significant differences were found on potentially infected patients’ management practices.

Background: Acceleration of mass vaccination strategies is the only pathway to overcome the COVID-19 pandemic. Healthcare professionals and students have a key role in shaping public opinion about vaccines. This study aimed to evaluate the attitudes of dental students globally towards COVID-19 vaccines and explore the potential drivers for students’ acceptance levels. Methods: A global cross-sectional study was carried out in February 2021 using an online questionnaire. The study was liaised by the scientific committee of the International Association of Dental Students (IADS), and data were collected through the national and local coordinators of IADS member organizations. The dependent variable was the willingness to take the COVID-19 vaccine, and the independent variables included demographic characteristics, COVID-19-related experience, and the drivers of COVID-19 vaccine-related attitude suggested by the WHO SAGE. Results: A total of 6639 students from 22 countries, representing all world regions, responded to the questionnaire properly. Their mean age was 22.1 ± 2.8 (17–40) years, and the majority were females (70.5%), in clinical years (66.8%), and from upper-middle-income economies (45.7%). In general, 22.5% of dental students worldwide were hesitant, and 13.9% rejected COVID-19 vaccines. The students in low- and lower-middle-income (LLMI) economies had significantly higher levels of vaccine hesitancy compared to their peers in upper-middle- and high-income (UMHI) economies (30.4% vs. 19.8%; p< 0.01). Conclusions: The global acceptance level of dental students for COVID-19 vaccines was suboptimal, and their worrisome level of vaccine hesitancy was influenced by the socioeconomic context where the dental students live and study. The media and social media, public figures, insufficient knowledge about vaccines, and mistrust of governments and the pharmaceutical industry were barriers to vaccination. The findings of this study call for further implementation of epidemiology (infectious diseases) education within undergraduate dental curricula.

The physical closure of higher education institutions due to coronavirus disease 2019 (COVID-19) shed a brighter light on the need to analyze, explore, and implement strategies that allow the development of clinical skills in a distance learning situation. This cross-sectional study aims to assess dental students’ self-perception, motivation, organization, acquired clinical skills, and knowledge using the online problem-based learning method, through the application of a 41-item questionnaire to 118 senior students. Answers were subjected to descriptive and inferential statistics analysis. Further, a principal component analysis was performed, in order to examine the factor structure of the questionnaire. Results show that online problem-based learning can be considered a relevant learning tool when utilized within the specific context of clinical dental education, displaying benefits over the traditional learning strategy. Overall, dental students prefer a hybrid system over the conventional one, in a distance learning context, and assume self-responsibility for their own learning, while knowledge thoroughness is perceived as inferior. This online active learning method is successful in improving information and clinical ability (visual/spatial and auditory) advancement in the scope of dental education, with similar results to presential settings. Further studies are required to assess clinical skill development through active learning methods, in a distance learning context.

In this study, we explore the diagnostic accuracy of a Radiographic-based Periodontal Bone Loss (R-PBL) method as a screening tool for periodontitis, in the form of radiographic bone loss, under the 2018 case definition in comparison to the 2012 case definition. The analysis was based on 456 patients (253 females and 203 males), screened for periodontal status in the Study of Periodontal Health in Almada-Seixal (SoPHiAS) project and subjected to a panoramic dental X-ray. Patients were diagnosed for the presence of periodontitis following the 2018 and 2012 case definition. R-PBL classification was defined by alveolar bone loss and diagnosed as no periodontitis (≥80% remaining alveolar bone), mild to moderate periodontitis (66% to 79%), or severe periodontitis (<66%). We appraise the X-ray quality to look for the influence on the performance of R-PBL. Sensitivity, specificity, accuracy, and precision, through several indicators, were determined. Performance measurement was assessed through binary and multiclass Receiver operating characteristic/are under the curve (ROC/AUC) analyses. Our results show that the tested R-PBL method under the 2018 case definition is a reliable tool in periodontitis cases screening. This method does not replace clinical periodontal evaluation, but rather, it screens patients towards a definitive periodontitis diagnosis. These results will contribute to support the development of automated prediction systems towards periodontitis surveillance.

Introduction: The knowledge of drinks' pH is essential for the development of preventive strategies in patients at risk of dental erosion [1 Reddy A, Norris DF, Momeni SS, et al. The pH of beverages available to the American consumer. Journal of the American Dental Association. 2016;147(4):255. doi:10.1016/j.adaj.2015.10.019[Crossref], [PubMed] , [Google Scholar]], since this defines the erosive potential of a drink. The critical pH, below which demineralization is expected to occur is 5.2–5.5 in enamel [2 Fisher BJ, Spencer A, Haywood V, et al. Relieving Dry Mouth: Varying Levels of pH Found in Bottled Water. Compendium of continuing education in dentistry. 2017;38(7):e17–e20.[PubMed] , [Google Scholar]]. Bottled water is often considered innocuous for dental tissues, both by patients and clinicians, and the erosive potential of different brands is neglected, especially in patients with dry mouth symptoms who need a strong water reinforcement [3 Brunstrom JM, Tribbeck PM, MacRae AW. The role of mouth state in the termination of drinking behaviour in humans. Physiology & behavior. 2000;68(4):579–583.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]]. The aim of this study is to demonstrate that bottled waters, commercialized in Portugal, have a minimum erosive potential for enamel, based on the measurement of their pH. Materials and methods: 31 different bottled mineral water, commercialized in Portugal, were analysed by means of the hydrogenionic concentration, by direct potentiometric measurement using a pH electrode calibrated in the range 4.01-10.00. Five independent pH measurements were recorded at 25 °C immediately after opening each bottle, for later calculation of the mean value and standard deviation. Results: From the 31 analysed bottled mineral water, three have shown a mean pH value within or very close to the critical pH range for demineralization (namely bottled waters Dia, Salutis and Vitalis), while the remaining 28 have shown to have mean pH values above. None of the measured waters had a pH mean value below 5.2 (Table 1). Discussion and conclusions: With the results of this preliminary study, we can demonstrate that bottled mineral waters commercialized in Portugal have minimal erosive potential on human dental enamel, based on the pH mean value. Nevertheless, it is essential for the clinician to be aware of the erosive potential of bottled water and educate patients as a preventive strategy. A further investigation concerning this area is needed for wider conclusions.
