The Centres for Disease Control and Prevention and the World Health Organization have developed preparedness and prevention checklists for healthcare professionals regarding the containment of COVID-19. The aim of the present protocol is to evaluate the impact of the COVID-19 outbreak among dentists in different countries where various prevalence of the epidemic has been reported. Several research groups around the world were contacted by the central management team. The online anonymous survey will be conducted on a convenience sample of dentists working both in national health systems and in private or public clinics. In each country/area, a high (~5–20%) proportion of dentists working there will be invited to participate. The questionnaire, developed and standardized previously in Italy, has four domains: (1) personal data; (2) symptoms/signs relative to COVID-19; (3) working conditions and PPE (personal protective equipment) adopted after the infection’s outbreak; (4) knowledge and self-perceived risk of infection. The methodology of this international survey will include translation, pilot testing, and semantic adjustment of the questionnaire. The data will be entered on an Excel spreadsheet and quality checked. Completely anonymous data analyses will be performed by the central management team. This survey will give an insight into the dental profession during COVID-19 pandemic globally.

Objectives A multicentre survey was designed to evaluate the impact of COVID-19 outbreak on dental practice worldwide, estimate the COVID-19 related symptoms/signs, work attitudes and behaviour and the routine use of protective measures and personal protective equipment (PPE). Methods A global survey using a standardized questionnaire with research groups from 36 countries was designed. The questionnaire was developed and pretested during April 2020 and contained three domains: 1) personal data; 2) COVID-19 positive rate and symptoms/signs presumably related to the coronavirus; 3) working conditions and PPE adopted after the outbreak. Countries’ data were grouped by the country positive rate (CPR) during the survey period and by Gross-National-Income per capita. An ordinal multinomial logistic regression model was carried out with COVID-19 self-reported rate referred by dental professionals as dependent variable to assess the association with questionnaire items. Results A total of 52,491 questionnaires were returned with a male/female ratio of 0.63. Out of the total respondents, 7,859 dental professionals (15%) reported symptoms/signs compatible with COVID-19. More than half of the sample (n=27,818; 53%) stated to use FFP2/N95 masks, while 21,558 (41.07%) used eye protection. In the bivariate analysis, CPR and N95/FFP2 were significantly associated (OR=1.80 95% CI=1.60/2.82 and OR=5.20 95% CI=1.44/18.80, respectively), while Gross-National-Income was not statistically associated with CPR (OR=1.09 95% CI=0.97/1.60). The same significant associations were observed in the multivariate analysis . Conclusions Oral health service provision has not been significantly affected by COVID-19, although access to routine dental care was reduced due to country-specific temporary lockdown periods. While the dental profession has been identified at high-risk, the reported rates of COVID-19 for dental professionals were not significantly different to those reported for the general population in each country. These findings may help to better plan oral health care for future pandemic events.

Introduction: Having in mind the importance of providing continuous pediatric dental services during the COVID-19 pandemic and the fact that children have similar viral loads to adults, the potential to spread the virus to others, and with variable clinical presentation of COVID-19 infection, this study aimed to analyze the impact of COVID-19 outbreak on pediatric dentistry service provision, risks, and preventive measures before and during dental treatment. Method: Structured and closed epidemiological cross-sectional survey involved seven Southeastern European countries. The questionnaire was developed using the modified Delphi method, pretested, and tested in North Italy during April 2020. The sample consisted of licensed dental professionals reached via national dental chambers and social media using the best strategies according to the national setting. Results: A total of 3227 dentists participated in the survey, and we included 643 specialists in this study—among them, 164 were pediatric dentists. Most pediatric dentists worked in the public sector (61.0%) and provided emergency (64.6%) and routine dental treatment (18.3%) during the outbreak. One-third of pediatric dentists were COVID-19 tested, statistically significantly more than other specialties, and 3.0% tested COVID-19 positive. In addition, significantly more pediatric dentists (13.4%) reported the presence of at least one symptom related to COVID-19 compared to other specialists (6.1%). None of the pediatric dentists reported PPE shortage. However, 26.2% of all specialists stated that they lacked clear step by step professional guidance in a national language. Similarly, in both groups, around 10% of specialists attended education on coronavirus. Conclusions: Considering that most pediatric dentists provided dental treatment during lockdown in their countries in public health centers and that they will continue to work during pandemic, our results suggest that pediatric dentists might be at higher risk of COVID-19 infection. Further research should focus on finding better ways to promote and adapt preventive, protective measures and PPE in the pediatric dental setting to be behaviorally acceptable. Moreover, additional efforts should be invested in dental education regarding COVID-19 in the mother tongue.
