ABSTRACT
Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2. (SARS-CoV-2). It spreads mainly through saliva droplets or nasal discharge. Dentists are among the professionals with the greatest risk of contracting and transmitting COVID-19. We compared the efficacy of surgical masks versus N95 respirators in preventing COVID-19 infection in dental settings. PubMed, Scopus, Web of Science, and Cochrane Library databases were searched. Search terms corresponded to a predefined PICOS (patient/population, intervention, comparison, and outcomes) question. The risk of bias was evaluated using AMSTAR-2 (A Measurement Tool to Assess Systematic Reviews-2), ROBIS (Risk of Bias in Systematic Reviews), and Health Evidence tools. A total of 191 articles were screened, and nine of them were further evaluated for eligibility, of which five articles (fulfilled the selection criteria) and were included in this study. Two studies concluded that surgical masks could provide equivalent protection to N95 respirators. Another study found that N95 respirators were superior to surgical masks. The fourth study found that better protection can be achieved when using surgical masks by the aerosol source than when the recipient uses an N95 respirator, while the last study concluded that surgical masks or N95 respirators alone do not provide full protection. Thus, according to this systematic review, N95 respirators provide better protection against COVID-19 infection compared to surgical masks.
ABSTRACT
OBJECTIVE: The aim of this study is to assess knowledge, attitudes, and clinical practices of dental professionals regarding the prevention and control of coronavirus disease 2019 (COVID-19) in Pakistan. MATERIALS AND METHODS: General dentists and dental specialists working in public and private dental practices, hospitals, and academic institutions participated in this cross-sectional study. A pilot-tested questionnaire was sent to dental professionals through an online link in Pakistan and data collection was completed in April-May 2020. The knowledge score was calculated from 22 variables about the COVID-19. RESULTS: The study included data of 343 dental professionals with 47.2% of males and 52.8% of females. The mean knowledge score was 16.78 ± 2.25, and it significantly differed between general dentists (16.55 ± 2.36) and dental specialists (17.15 ± 2.04) (p = 0.020), and those with up to 10 years of experience (16.58 ± 2.28) and those with more than 10 years of experience (17.05 ± 2.2) (p = 0.026). Only 15.5% of the participants were comfortable in treating patients during the COVID-19 pandemic. A workshop/seminar on the COVID-19 was attended by 23% of the participants. In multivariate analysis, being comfortable in treating patients (odds ratio = 3.31, 95% confidence interval = 1.63, 6.73) was associated with the attendance of workshop/seminar on COVID-19. CONCLUSIONS: Dental professionals had adequate knowledge about COVID-19, but a few of them were comfortable in treating patients during the pandemic. A minority of dental professionals attended a workshop/seminar on the COVID-19. Continuous education activities should be provided to dental professionals to enhance their role in the prevention of COVID-19 spread and promotion of oral health.
ABSTRACT
OBJECTIVE: The aims of this study were to investigate the awareness, knowledge, and attitudes of Pakistani medical and dental undergraduate students toward COVID-19 during the surge of its outbreak. MATERIALS AND METHODS: The multicentered, cross-sectional study was carried out nationwide among undergraduate medical and dental students. A convenience sampling technique was used. A self-developed online questionnaire was pretested to be completed by the participants. It was distributed using social media. The survey was comprised of questions related to demographics, health status, general hygiene perception, understanding, and the learning attitudes of the students. Comparisons of the knowledge scores and the attitude responses with the demographic information were done using the independent t-test, one-way ANOVA, and Chi-square, as appropriate. RESULTS: Of the 937 total respondents, 353 (38%) were males and 582 (62%) were females; two students did not mark their gender. Of these, 680 (73%) were dental students and 257 (27%) were medical students. The mean knowledge score of the female dental students (5.15 ± 1.08) was significantly higher than that of the male students (4.87 ± 1.09). Overall, the mean knowledge score was statistically higher among the medical students in comparison to the dental students (5.21 ± 1.15, 5.05 ± 1.09; p = 0.054), respectively. CONCLUSION: The medical and dental students were both aware of the importance of the use of a mask. The medical students had a greater awareness regarding the mode of transmission, symptoms, and origin of COVID-19. However, the dental students showed better understanding of the use of surgical masks and the correct protocol for hand washing. Social media was considered the main source for COVID-19 related information.
ABSTRACT
Recently, there have been many global outbreaks of diseases. The latest is the coronavirus disease of 2019 (COVID-19) pandemic. The virus has spread worldwide and is transmitted mainly through droplets or by touching contaminated surfaces. Globally, healthcare systems are challenged due to a lack of workplace safety and professional obligations in addition to the rapid spread of the virus. Dental facilities are at greater risk due to the nature of dental care. The aim of this review study was to provide a situational analysis within dental facilities during the new COVID-19 outbreak. Published papers concerning dental facilities and COVID-19 were retrieved from PubMed, search engines, and organizational websites. All data were reviewed, arranged into themes, and then categorized either as strengths or weaknesses with respect to addressing the COVID-19 pandemic in dental facilities, and accordingly, threats and possible opportunities to the handling of the pandemic were identified. Preparedness of dental facilities during the current pandemic is a weakness that needs to be addressed promptly. Shortage of dental care providers, cyber security, economic losses, and ethical challenges are possible threats due to the current outbreak. Coordination and prompt communication among all healthcare providers during such outbreaks is a strength that needs to be supported. This strengths, weaknesses, opportunities, and threats (SWOT) analysis can be a useful tool for guiding decision-making as it is crucial during the current pandemic to work on weaknesses, avoid threats, and utilize all future opportunities.
