The unfold of coronavirus illness 2019 (COVID-19) has posed important challenges for dentistry and drugs. The chance of nosocomial transmission led the routine dental care to be temporally suspended in a number of European international locations experiencing COVID-19 (Coulthard, 2020), and it was restricted to emergency remedies (Gurzawska-Comis et al., 2020). Numerous measures, together with the usage of further private protecting tools (PPE), have been proposed by nationwide and worldwide tips to attenuate an infection dangers (Pan et al., 2020; Ren et al., 2020). Nonetheless, attributable to an especially giant demand worldwide, restricted safety measures had been out there for the availability of dental remedies (Coulthard, 2020).
The shortage of scientific proof on the efficacy of preventive measures accelerated analysis tremendously, which, nevertheless, has not develop into complete up to now (Majumder & Mandl, 2020; Zimmermann & Nkenke, 2020). As well as, attributable to quick observe evaluation and time strain, publications appeared on-line earlier than thorough peer-review course of. This made assessing the standard of the out there proof more difficult and likewise extra related than ever. Subsequently, our analysis group reviewed the present proof and proposals not too long ago (Gurzawska-Comis et al., 2020). It was reported that literature and proposals had been primarily primarily based on extreme acute respiratory syndrome (SARS) and Center East respiratory syndrome (MERS).
One other method to gather proof is a survey of consultants, that enables quick and high-quality knowledge assortment (Atkins et al., 2004). As a result of pressing want for dependable suggestions, the authors hypothesized that analysis gaps may be crammed by asking worldwide consultants on the frontline for his or her opinions.
The aim of this research was to survey European consultants about their opinion on PPE, affected person triage and extra measures in dental settings throughout COVID-19 pandemic.
2 MATERIAL AND METHODS
A survey was designed to establish the opinions and the expertise of educational European consultants in Oral and Maxillofacial Surgical procedure or Oral Surgical procedure, concerned within the dental emergency care through the outbreak of COVID-19. The research protocol was submitted to and authorised by the Moral Committee of the College of Dusseldorf (Protocol no. 2020–926). The acknowledged requirements had been adopted (Declaration of Helsinki; European Medicines Company Tips for Good Medical Apply). The current research was additionally performed and reported based on the “Good follow within the conduct and reporting of survey analysis” standards (Kelly et al., 2003).
2.1 Research inhabitants
For every of the 27 member international locations of the EU and for five further European international locations (Iceland, Norway, Moldova, Switzerland, UK), a survey invitation was despatched by e mail to at least one educational skilled in Oral and Maxillofacial Surgical procedure or Oral Surgical procedure (ideally head of the division). The choice of the contributors was primarily based on word-of-mouth communication and by hand search of College web sites. The invitation e mail defined the purpose of the research and included the hyperlink to the consent type and on-line survey. If the reply was not offered throughout the given deadline, a second skilled from the respective nation was contacted. If the second skilled didn’t reply in time, a 3rd skilled was requested. If no response was retrieved, the nation was labelled as not-responding.
The participation within the survey was voluntary and with none incentive. All responders signed an knowledgeable consent type earlier than accessing the questionnaire by a web based survey platform (SurveyMonkey®). Knowledge assortment happened between twelfth April and twenty second Might 2020. Knowledge had been assessed, saved and processed anonymously.
A structured questionnaire together with 10 gadgets was developed (Attachment 1). The survey was evaluated in a pilot part by 5 Oral Surgeons affiliated to European universities that had been chosen primarily based on the skilled community of the authors. The questionnaire was amended primarily based on their suggestions, to keep away from redundancies and ambiguities within the remaining survey. The COVID-19 threat classification based on Gurzawska-Comis et al.  was offered: Unknown threat: (no flu-like signs) AND (no contact with COVID-19-positive sufferers); Excessive threat: (flu-like signs + no contact with COVID-19-positive affected person) OR (no flu-like signs + contact with COVID-19-positive affected person); Very excessive threat: COVID-19 constructive or flu-like signs + contact with COVID-19-positive sufferers.
The questionnaire coated the next areas:
- Participant working atmosphere (2 gadgets, single selection);
- An infection threat of dental well being professionals (2 gadgets, single selection);
- Beneficial PPE for dental well being professionals (2 gadgets, matrix/a number of choose);
- Amenities for dental therapy of COVID-19-positive sufferers (1 merchandise single selection);
- Measures to stop an infection of well being professionals and nosocomial transmission in dental clinics (2 gadgets, matrix/single selection per row);
- Details about the place dental care was offered for sufferers with a excessive threat of COVID-19 (1 merchandise, a number of choose).
The problems on the working atmosphere included two questions. The consultants had been requested whether or not they handled sufferers within the personal and/or college dental clinic settings (query 1) and in regards to the variety of employees members working of their departments was additionally investigated (query 2). The an infection threat of dental well being professionals needed to be scored for aerosol-free and aerosol-generating procedures (questions 3 and 4).
Questions 5 and 6 investigated consultants’ advice concerning PPE for dental well being professionals through the pandemic for aerosol-free or aerosol-generating procedures.
In query 7, it was requested the place COVID-19-positive sufferers ought to be handled in case of urgency. The relevance of varied measures to stop an infection transmission in dental settings was investigated in questions 8 and 9. Info on the dental setting the place sufferers with (excessive) threat of COVID-19 had been handled throughout pandemic was obtained in query 10.
2.3 Statistical evaluation
The information evaluation was carried out utilizing Microsoft Excel® for Mac model 16.37 (Microsoft®, USA). For every query, absolutely the variety of votes and the relative settlement (%) had been calculated. As just one group was surveyed (consultants in oral surgical procedure), no comparative analyses had been carried out.
In whole, consultants from 27 (84%) international locations out of 32 responded to the survey (Determine 1). To the primary spherical of invitation, 13 consultants from the respective international locations responded, whereas to the second spherical 10 remaining international locations replied. A complete of 4 international locations responded to the third spherical. The imply period of answering the questionnaire was seven minutes. Particulars on the adhere to the “Good follow within the conduct and reporting of survey analysis” standards for questionnaire research are reported in attachment 2 (Kelly et al., 2003).
3.1 A) Participant working atmosphere
Eleven respondents (40.5%) acknowledged to deal with sufferers on the Dental College Hospital, and one other eleven (40.5%) indicated therapy in each personal follow and Dental College Hospital. 5 contributors (18.5%) reported to be working clinically in personal follow solely. The variety of employees members working of their division was heterogeneous: 0–10 (5 contributors,18.5%), 11–20 (6 contributors, 22.2%), 21–30 (5 contributors, 18.5%), 31–50 (4 contributors 14.8%), 51–100 (6 contributors, 22.2%), >100 (1 participant, 3.7%).
3.2 B) an infection threat of dental well being professionals
For aerosol-free remedies, 4 consultants (14.8%) discovered the danger to be low, whereas eleven rated the danger to be impartial (40.7%) and twelve (44.4%) thought of the danger to be excessive. For aerosol-generating procedures, two consultants scored the danger to be impartial (7.4%) whereas 25 (92.6%) to be excessive.
3.3 C) Beneficial ppe for dental well being professionals
For aerosol-free procedures, the suggestions different for the totally different PPE measures (Desk 1). Nearly all of consultants really useful FFP2/FFP3 masks for treating sufferers at unknown (66.7%), excessive (88.9%) and really excessive (96.3%) threat, whereas just one skilled discovered FFP2/FFP3 not related for aerosol-free procedures.
|Unknown COVID−19 threat||Excessive COVID−19 threat||Very excessive COVID−19 threat solely||None|
|FFP2/FFP3 masks||66.7% (18)||88.9% (24)||96.3% (26)||3.7% (1)|
|Face defend/goggle||81.5% (22)||88.9% (24)||96.3% (26)||3.7% (1)|
|Overshoes||40.7% (11)||66.7% (18)||70.4% (19)||29.6% (8)|
|Robe||66.7% (18)||85.2% (23)||92.6% (25)||7.4% (2)|
|Cap||85.2% (23)||92.6% (25)||100% (27)||0% (0)|
|Double gloves||40.7% (11)||63.0% (17)||74.1% (20)||25.9% (7)|
- Danger classification: Unknown threat: (no flu-like signs) AND (no contact with COVID-19-positive sufferers); Excessive threat: (flu-like signs + no contact with COVID-19-positive affected person) OR (no flu-like signs + contact with COVID-19-positive affected person); Very excessive threat: COVID-19 constructive or flu-like signs + contact with COVID-19-positive sufferers
Comparable replies had been noticed for face shields and goggles. Nonetheless, there was a pattern in the direction of recommending face safety for dental employees whatever the sufferers’ particular person threat (22 consultants, 81,5%). Overshoes had been much less appreciated and weren’t really useful in any respect by 29.6% of the consultants. Robes had been really useful by comparable numbers of consultants for sufferers with unknown (18 consultants, 66.6%), excessive (23 consultants, 85.2%) and really excessive threat (25 consultants, 92.6%). In distinction, caps had been steadily really useful for each therapy whatever the particular person threat (23 consultants, 85.9%), whereas no consultants discovered this measure ineffective for aerosol-free procedures (Desk 1).
When contemplating aerosol-generating procedures, FFP2/FFP3 masks, face shields, overshoes, robes and double gloves had been really useful by nearly all of contributors. In distinction to aerosol-free procedures, many of the PPE was additionally really useful when treating sufferers with unknown COVID-19 threat (Desk 2).
|Unknown COVID−19 threat||Excessive COVID−19 threat||very excessive COVID−19 threat||None|
|FFP2/FFP3 masks||77.8% (21)||96.3% (26)||100% (27)||0% (0)|
|Face defend/goggle||92.6% (25)||100% (27)||100% (27)||0% (0)|
|Overshoes||55.6% (15)||74.1% (20)||77.8% (21)||22.2% (6)|
|Robe||81.5% (22)||88.9% (24)||88.9% (24)||11.1% (3)|
|Cap||88.9% (24)||96.3% (26)||100% (27)||0% (0)|
|Double gloves||51.8% (14)||66.7% (18)||74.1% (20)||25.9% (7)|

3.4 D) Amenities for dental therapy of COVID-19-positive sufferers
A complete of 18 consultants (66.7%) responded that dental remedies of COVID-19-positive sufferers ought to be carried out at Dental College Hospitals. The remaining 9 contributors (33.3%) prompt personal follow and Dental College Hospitals as eligible. Non-public practices, in distinction, weren’t discovered to be the one setting for pressing therapy of COVID-19-positive sufferers.
3.5 E) Measures to stop an infection of well being professionals and nosocomial transmission in dental clinics
The vast majority of consultants (25 consultants, 92.6%) really useful treating COVID-19-positive sufferers in separate isolation rooms and minimizing aerosol-generating procedures (27 consultants, 100%). Moreover, limiting the contact between employees members was discovered related by many of the consultants (23 consultants, 85.2%). Nearly all of contributors additionally discovered the usage of rubber dam, extraoral radiographs, air disinfection and pure air air flow related (Determine 2).
Nearly all of patient-related measures had been discovered related to restrict the danger of COVID-19 transmission. All of the consultants agreed that the variety of sufferers in ready space and the time they spend there ought to be minimized. Telephone interviews to evaluate the well being standing (COVID-19 threat evaluation) had been scored to be extremely related (81.5%). In distinction, assessing affected person therapy wants through cellphone was authorised by 66.7% of the consultants solely. The hand hygiene was thought of to be essential (100%), whereas surgical masks put on contained in the clinic was barely much less authorised (70.4%) (Determine 3).
3.6 F) Details about the place dental care was offered for sufferers with a excessive threat of COVID-19
Within the majority of nations (70.4%), the Division of Oral Surgical procedure was offering emergency dental care throughout knowledge assortment. The Division of Oral and Maxillofacial Surgical procedure was reported to be concerned in 55.6% of the international locations. In 37.0%, personal practices had been offering dental therapy for COVID-19-positive sufferers or sufferers being at excessive threat. Emergency items provided dental care in 22.2% of the international locations. No therapy was carried out on the affected sufferers in 3.7% of the international locations.
Provision of dental care throughout this pandemic is difficult due to the excessive transmission threat in dental settings (Ather et al., 2020; Izzetti et al., 2020; Meng et al., 2020). As dental care can’t be postponed for longer episodes, eligible precautionary measures need to be carried out quickly to make sure security in dental settings (Gurzawska-Comis et al., 2020). Presently (Might 2020), managed scientific trials on COVID-19 in dentistry are usually not but out there and they don’t seem to be more likely to be possible owing to moral causes. To supply interim evidence-based drugs suggestions, the analysis gaps will be full of skilled opinions (World Well being, 2014). Subsequently, the current research aimed to gather the opinion of consultants working on the frontline concerned in emergency dental care through the pandemic. These consultants’ statements are presupposed to complement our earlier evaluation of the out there literature and nationwide in addition to worldwide tips (Gurzawska-Comis et al., 2020). All consultants chosen to take part on this research had been primarily based at European Universities.
The transmission threat for aerosol-free procedures in dental settings was thought of to be low or impartial by roughly 55% of the consultants, whereas for aerosol-generating procedures, the overwhelming majority (93%) agreed that the danger was excessive. Regardless of of the heterogenic responses associated to aerosol-free procedures, metadata (working atmosphere) might solely partially clarify the various solutions. Specialists working not completely at college hospitals tended to fee the danger of aerosol-free procedures larger. In distinction, 64% of the consultants working at college hospitals thought of the danger to be low or impartial. As knowledge couldn’t be matched with the consultants’ house nation, the affiliation with nationwide COVID-19 prevalence couldn’t be evaluated.
Amongst really useful PPE, face shields, robes, and caps had been scored the very best for sufferers of unknown COVID-19 threat. FFP2/3 masks had been really useful by virtually 80% of consultants for aerosol-generating procedures for sufferers of unknown threat, and consultants agreed that FFP2/3 masks, face shields and caps ought to be used for aerosol-generating procedures in sufferers at excessive or very excessive threat. Specialists prompt that sufferers with excessive and really excessive threat ought to be handled with FFP2/3 masks, face shields and caps regardless of on the kind of process.
Overshoes and double gloves had been judged not helpful by nearly all of the respondents, and this appraisal could also be associated to the restricted proof out there (Verbeek et al., 2020).
Nonetheless, proposed PPE measures had been extra homogenous for aerosol-generating procedures, whereas larger disagreement was discovered for aerosol-free procedures. This would possibly mirror a scarcity of scientific proof and unclarity in the direction of the transmission threat throughout aerosol-free procedures.
Two thirds of the consultants prompt to deal with COVID-19-positive sufferers throughout pandemic solely in College Hospitals, whereas one third prompt to deal with them additionally in personal places of work. Not one of the contributors thought of personal follow as the one setting for treating contaminated sufferers.
All consultants agreed on the significance of decreasing aerosol-generating procedures and 92% of the consultants prompt treating COVID-19-positive sufferers in isolation rooms. In distinction, air disinfection was prompt by 60%.
To scale back the variety of doubtlessly contaminated sufferers in dental settings, a phone threat evaluation was discovered to be useful. Nonetheless, about one third of the consultants didn’t counsel assessing therapy wants through cellphone, thus emphasizing the significance of nose to nose contact throughout scientific examination. Not one of the consultants prompt that dental care throughout pandemic ought to be restricted to non-public practices, and the bulk discovered solely dental hospitals to be applicable. This can be associated to the lockdown of dental places of work in a number of European international locations when the survey was performed.
A excessive proportion of consultants really useful carrying of masks by sufferers in dental settings, despite the fact that this safety measure was not but really useful by World Well being Group (WHO) throughout knowledge assortment. This may occasionally mirror the yearlong expertise of dentists being uncovered to a number of infectious illness.
Earlier research associated to SARS-CoV-1 reported implementation of common precautions, each time an aerosol is produced (e.g. preprocedural mouth rinse) (Harrel & Molinari, 2004). The applying of an infection management methods is widespread in dentistry and it’s a milestone in dental schooling at universities these days (Heinzerling et al., 2020; Oosthuysen et al., 2014).
Since June fifth 2020, group masks put on is really useful by WHO (World Well being, 2020). As carrying masks by sufferers throughout dental therapy is not possible, mouth wash could cut back the viral load. Certainly, 80% of consultants really useful this measure even earlier than it was really useful by WHO. Nonetheless, only a few research exist on the efficacy and substantivity of mouth rinses to eradicate viral load throughout therapy (Carrouel et al., 2020; Peng et al., 2020).
In abstract, consultants’ suggestions revealed excessive settlement, particularly for PPE measures throughout aerosol-generating procedures. This underlines the significance of face safety utilizing FFP2/3 masks, shields and caps in addition to discount of aerosol-generating procedures.
The survey inhabitants was supposed to symbolize the opinion of European consultants dealing with dental emergencies throughout pandemic. As nearly all of the emergencies are offered by Oral Surgical procedure or Oral and Maxillofacial Surgical procedure departments (Scottish Dental Medical Effectiveness Programme, 2007), the respective heads or professors had been chosen to be included. Some international locations had only a few dental colleges. Thus, contemplating a couple of skilled vote per nation would have required aggregation to stop imbalance. As well as, the respective query for the origin would have been in battle with our nameless method in small international locations (i.e. making it not possible to allocate consultants and solutions). Subsequently, to make sure homogenous representativity, one skilled vote was permitted per nation solely. As well as, all consultants had been chosen independently of age and gender.
Limitations related to the current research embody that the affect of nationwide tips and native rules on consultants’ solutions couldn’t be assessed owing to the nameless method. Furthermore, the survey was carried out throughout an exponential progress part (6 weeks), during which consultants might need tailored to the scenario. Moreover, the current suggestions had been collected when solely emergency care was offered in many of the international locations. As a result of similarity between emergency and different elective oral surgical procedure remedies, the current suggestions will be utilized in implant dentistry. As basic dental practitioners and specialists (endodontists, orthodontists, periodontists, prosthodontics) offering elective remedies are actually re-opening their places of work, larger-scaled surveys will likely be attainable within the close to future. They might embody additional questions on the relevance of qualitative and quantitative testing for COVID-19, novel high-efficiency particulate air (HEPA) filtration gadgets for dental places of work, or high-power suction.
In conclusion, the an infection and transmission threat in dental settings was scored to be explicit excessive. For aerosol-generating procedures and sufferers at excessive/very excessive threat, most PPE use was really useful. Whereas the proposed measures (i.e. FFP2/3 masks, caps, robes and face safety) could cut back the transmission threat in dental hospitals, future survey ought to be performed amongst a bigger inhabitants of dentists in addition to amongst consultants in virology and an infection management. Sooner or later, additionally in vitro experiments and epidemiological research would reveal useful details about the transmission threat related to the particular dental procedures. Lastly, future threat evaluation would possibly embody further components, akin to the present prevalence per 100,000 inhabitants, age distribution of the sufferers, and social and economical standing.
