Ninety-three percent of the participants have stated that health care professionals must clean their hands often, cover their nose and mouth, and maintain safe distance from everyone in order to prevent the virus from affecting them. Sixty-three percent of the participants are familiar with the term PPE. Majority assume that health care professionals are given enough safety precautions while treating a patient with coronavirus.

 Hence, to conclude, health care professionals play a vital role in improving access and quality health care for the population, and hence, they must be protected as well. Since dental students treat patients, they are vulnerable to infection as well, and must take proper safety measures.

 Hence, to conclude, health care professionals play a vital role in improving access and quality health care for the population, and hence, they must be protected as well. Since dental students treat patients, they are vulnerable to infection as well, and must take proper safety measures.The purpose of the present narrative review was to evaluate and discuss the actual available information regarding coronavirus disease 2019 and dental practice, and to share recommendations with the intent to help dentists in providing a safe and healthful workplace during pandemic. A step-by-step workflow is presented including prevention and measures to reduce risk for cross infections before, during, and after the dental treatments. Individualization of different risk-level zones and the establishment of a team-based chain control is also presented. The present manuscript may offer deeper knowledge and discussion regarding recommended procedures aimed to reduce risk for dental health care workers contamination and cross infections. Within these, infection prevention in dental settings, respect of general rules, containment measures, proper use of the personal protective equipments (PPE), and well-organized chain control of all the staff, with definition of risk zones and specific responsibility could be an adjunctive but important step to control the spread of the disease.

 Evaluating the potential remineralization effect of NovaMin prophylaxis paste on artificial enamel lesions in primary teeth using Vickers microhardness and scanning electron microscope.

 Forty sound buccal and lingual surfaces of human primary canine teeth were randomly divided into two groups after creating artificially demineralized lesions (G1 NovaMin and G2 fluoride; 20 per group) and then treated with the respective remineralization agents. The remineralization cycle repeated twice daily for 10 days. The groups were evaluated with Vickers microhardness and scanning electron microscope before and after de/remineralization.

 Statistically significant difference of microhardness was observed between demineralized enamel and remineralized enamel with group 1 and group 2 (

= 0.000 and

= 0.000, respectively). No statistically significant difference of microhardness was observed between two remineralized agents (

= 0.368).

 Within the limitation of this

study, NovaMin enhances the remineralization process equally to fluoride.

 The coronavirus disease 2019 (COVID-19) pandemic has affected professionals in all fields; none more so than medical and dental professionals. As dental core trainees (DCT) working in hospitals, we have been at the forefront of the crisis and one of the first in line for redeployment. Therefore, we decided to investigate the impact of COVID-19 on the redeployment of DCTs across the UK.

 Data for this study was collected and shared between three project researchers. All researchers were undergoing dental core training in Oral Surgery and Restorative dentistry at Guy’s Hospital, London. An online survey was sent out via email and online social media platforms to reach as many DCTs as possible in the United Kingdom. Implied consent was obtained by respondents on submission of the survey.The survey consisted of five sections and was branched, with respondents answering different sections depending on their redeployment status. No qualitative data was collected, as all questions included in the survey were die anxiety as a result. see more Inevitably, this has resulted in disruption to their training program and education over the last few months. The response across the United Kingdom has been understandably variable due to the differing demands of the hospital trusts within which the DCTs work.

 In response to the coronavirus disease 2019 (COVID-19) pandemic, the Indian Government imposed a countrywide lockdown of 21 days from March 25 to April 14, 2020, which was further extended to 60 days. The sudden draconian measures changed the delivery of dental education and practice throughout the country. The study aimed to screen for depression during the COVID-19 lockdown and the factors associated with it among dental students and practitioners in highly COVID-19 infected states of India.

 The current study is an online cross-sectional survey performed in Delhi NCR, Maharashtra, and Tamil Nadu during May 2020. The participants were recruited by convenience sampling. The main outcome measure was the screening of depression using the Patient Health Questionnaire (PHQ-9), which was categorized as mild, moderate, and severe depression. The data analysis was performed with IBM SPSS Version 23.0. A multivariable logistic regression model was fitted to identify the independent predictors of depression.

 The results of this study indicate a high level of depression among a significant number of dental students and practitioners. It is important to monitor and address the mental health needs of dental students and practitioners during and after the lockdown.

 The influence of different light-emitting diode (LED) curing light intensities on the degree of conversion (DC) and volumetric polymerization shrinkage (VPS) of bulk-fill resin-based composite (RBC) restorative materials was evaluated.

 Twenty-four specimens of each RBC material (Filtek one bulk-fill posterior, Reveal HD Bulk, Tetric N-Ceram, and Filtek Z350) were prepared. The RBCs were shaped in molds and cured using an LED curing light unit at high-intensity (1,200 mW/cm

) for 20 seconds and low-intensity (650 mW/cm

) for 40 seconds Fourier-transform infrared (FTIR) spectroscopy was used to determine the DC and microcomputed tomography was used to evaluate VPS. Data were analyzed using one- and two-way ANOVA, independent

-test, and Tukey’s and Scheffe’s post hoc multiple comparison tests.

 With high-intensity curing light, Reveal HD showed the highest DC (85.689 ± 6.811%) and Tetric N-Ceram the lowest (52.60 ± 9.38%). There was no statistical difference in VPS when using high- or low-intensity curing light.
