The epidemic coronavirus disease 2019 (COVID-19) has infected millions of people and put a huge amount of stress on the health-care system. Health-care professionals, including dental professionals, are at a high risk of acquiring COVID-19. Therefore, extra precautions need to be implemented for routine dental infection control procedures. It is encouraged to have a written reminder in the form of a checklist to recall these crucial steps, especially when nonroutine procedures must be followed. The aim of this special communication is to present a proposed mnemonic or memory-recall, user-friendly checklist to be used in the dental clinic during the COVID-19 outbreak. The checklist was created following the guidelines for reopening dental services in governmental and private sectors during the COVID-19 pandemic that were published by the Ministry of Health on June 5, 2020. Based on the patient's score and the urgency of the dental situation, specific steps should be followed. When the patient's score is ≥ 4 and needs an emergency aerosol-generating procedure, REDS steps should be recalled. Further, MRS steps must be followed if the patient's score is < 4. For both groups, GAMES can be followed when personal protective equipment is needed before the patient examination and HD steps should be applied after finishing the dental procedure. In conclusion, this written reminder in the form of a checklist can be helpful for a safe dental practice during pandemics to recall the crucial nonroutine steps. We recommend that the dental staff place those steps as a written reminder in an accessible, visible place.

| Introduction|| |
The coronavirus disease 2019 (COVID-19) is an infectious disease caused by the novel coronavirus (2019-nCOV), also known as the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). It is classified as a new strain of the coronaviruses family that targets the airways and has not been detected in humans before.,,, COVID-19 causes respiratory infections that range from common cold-like symptoms to the more severe illnesses similar to the Middle East respiratory syndrome (MERS-CoV) and SARS-CoV., In addition, it can also cause dyspnea, severe lung congestion, arrhythmia, acute myocardial injury, acute liver injury, and multiorgan failure such as respiratory failure.
As of August 2020, the COVID-19 pandemic represents an extraordinary public health crisis that has affected over 22 million of the population worldwide.
COVID-19 can spread by mucus or droplets that are expelled through the nose or mouth when an infected individual coughs or sneezes. In addition, it can be indirectly transmitted via contact between the hands/oral mucosa and the contaminated surfaces. More importantly, as a case report of COVID-19 infection in Germany revealed, the transmission of the virus can occur via contact with asymptomatic patients as well., Furthermore, other studies indicated that COVID-19 infection could be transmitted through fecal–oral route. Studies also suggested that medical/dental procedures such as aerosol-generating procedures (AGP) can transmit COVID-19 infections. Therefore, everyone in the sustained transmission phase of COVID-19 needs to consider that anyone might have the virus and act accordingly.
Countries' first action toward COVID-19 was the implementation of curfew laws toward the pandemic, including school closures, shopping malls' closures, plane groundings, and business/major event lockdowns. Furthermore, people have been instructed to stay at home, but are allowed to leave home for necessities such as food, medical reasons, or for work. Due to the escalating numbers of cases, many countries were providing ample tests for free to people with symptoms and are conducting active screening in crowded areas where there is a high number of confirmed cases. On August 15, 2020, the total number of cases reached 297,315 since the start of the outbreak in Saudi Arabia. In addition, the number of recovered cases and fatalities reached 264,487 and 3369, respectively [Figure 1].
In many countries, all routine medical/dental care and elective surgical procedures were postponed until further notice to avoid sustained transmission of COVID-19.,,, In March 16, 2020, the American Dental Association recommended postponing elective procedures until April 18, 2020, when they released the new interim guidance to help dentists during the reopening process to help reduce the risk of exposure to infection. In the case of Saudi Arabia, the Saudi Ministry of Health (MOH) recommended that all essential dental procedures, including emergencies, during the COVID-19 pandemic, must be provided with a high level of infection control protocol supported by suitable personal protective equipment (PPE). In particular, the MOH recommended avoiding AGPs, unless they fall under the category of dental emergencies, and published a guideline regarding dental emergencies during the COVID-19 outbreak. On June 5, 2020, the MOH published guidance for the reopening of dental services in governmental and private sectors – as the COVID-19 pandemic continues. In response, this special communication aims to present a proposed mnemonic, or memory-recall, user-friendly checklist to be used in dental clinics during the COVID-19 outbreak.
Dental practitioners are at a biological risk of infection due to the exposure to pathological microbes from the patient's oral cavity and respiratory tract. Studies have shown that face-to-face contact and day-to-day exposure to contaminated saliva, blood, and conjunctival/nasal mucosa could transmit respiratory infections., Moreover, dental staff is at possible extra risk of infection from the handling of sharp instruments. Studies have suggested that respiratory infection can be directly transmitted through the inhalation of airborne microbes that are present in the air, or indirectly transmitted by contact with contaminated instruments or inanimate surfaces.,,
AGPs, which include the use of high-speed handpieces, ultrasonic scaler, and triple syringes during dental procedures, can cause the spread of infection through the production of a significant amount of droplets and aerosols mixed with a patient's blood or saliva., It is recommended that the dental clinic environment must be under the highest infection control standards as part of dental care workers' routines to prevent the transmission of microbiological contaminations. This cannot be emphasized enough especially during a public health crisis.
It has been documented that extended exposure to AGP along with poor infection control could be associated with an increased risk of acquired infections. Moreover, inadequate handwashing, inadequate social distancing, and inadequate use of PPE can contribute to an increased risk of infection. A study conducted in China reported that a large number of medical staff became infected with COVID-19 during this pandemic.
Several guidelines provide recommendations to minimize or prevent the risk of transmission associated with AGP during the COVID-19 outbreak.,,, To prevent the spread of COVID-19, dental staff must not only be aware of the way that COVID-19 is transmitted but also be able to identify patients at risk and implement appropriate infection control measures in the dental practice.
The need for the development of a mnemonic checklist
It is important for health-care workers during the COVID-19 pandemic to follow the recommended guidelines in both emergencies and routine dental care to decrease the chance of possible unfavorable consequences and improve standards of patient care., Moreover, it has been documented that during stressful conditions such as the COVID-19 outbreak, memory, awareness, and cognitive functions could be adversely influenced. Hales et al. suggested that the development of a checklist might be required to not only help staff and minimize the risk of medical errors but also ensure patient safety. Hence, a useful checklist should improve performance in stressful environments by increasing mental competence to perform important tasks correctly.
A checklist is a directory of actions, procedures, or behavior that highlights the essential measures of a particular task or a set of tasks., It aims to assist in recalling critical criteria, ensure standardization of practice, and maintain reproducibility in assessments., Studies recommend one of the two main types of checklists: evaluative or mnemonic. An evaluative checklist is used to standardize evaluation by using specific guidelines for assessment while maintaining further authority and uniformity among the evaluators. A mnemonic checklist is used as a reminder system not only to help standardize routine or complex procedures but also to provide an organizational structure for a quick memory recall of crucial information during periods of stress or crisis. It is suggested that medical mnemonic checklists can be designed to support a medical/dental team through a process with a standard outline. At the same time, the mnemonic checklist should be concise and condense the number of bits of knowledge to help focus on the most critical areas.
| Discussion of the Checklist|| |
The proposed checklist [Appendix 1] was obtained from the guidelines for reopening dental services in governmental and private sectors during the COVID-19 pandemic that was published by the MOH. However, this checklist highlights the important procedures that must be undertaken in the dental clinic, starting from the patient evaluation until the dismissal from the clinic during the COVID-19 outbreak. These procedures are divided into three main stages: before the patient enters the clinic, while the patient is in the clinic, and after the patient leaves the clinic. Based on the respiratory triage checklist (RTC) score, the checklist is further divided into two main sections: protocol A is followed when the RTC score is ≥4 and protocol B is followed if the RTC score is <4. Each patient must be carefully triaged and scored before the dental examination.
The RTC score consists of a number of questions about the exposure risk to COVID-19 and the clinical signs and symptoms. Each question has an assigned score. The total score should be calculated by adding the patient's score for each question. According to the patient score, the responsible dentist must evaluate the urgency of the dental condition and decide whether to provide or defer dental care. For example, febrile patients with respiratory symptoms will fall under section A and should not receive dental treatment unless it is urgent. According to the checklist, if the emergency AGP dental procedure was necessary when the patient's score is ≥4, REDS steps should be recalled, whereas MRS steps must be retrieved if the patient's score is <4. However, for both groups, we suggest that GAMES be followed when PPE is needed before examination, and HD steps should be used after finishing the dental procedure [Appendix 1]. Because those mnemonic checklists are meant to facilitate easy recall, the mnemonic abbreviations are explained as follows: The REDS steps denote Rubber dam, Emergency dental procedure, Dental clinic, and Suction, whereas MRS steps stand for Mask, Rubber dam, and Suction; GAMES steps indicate Gown, Anti-septic mouthwash, Mask, Eye protection, and Shoes and protective head covering; and HD steps denote Hand hygiene and Doffing of PPE.
Standard infection control guidelines, including the use of PPE, are well known by dental professionals. Unlike normal dental settings, the current checklist emphasizes two levels of PPE that depend on the patient's RTC score. The first level includes standard PPE, comprised of an isolation gown, surgical mask, eye protection (such as goggles or a face shield), and protective headcover, which is recommended for use when examining a patient with an RTC score <4. The second level of PPE is comprised of a surgical gown, N95 mask with eye protection, and protective headcover, which must be used during the examination of a patient with an RTC score ≥4. Of note, a power air-purifying respirator can be used instead of the N95 mask as the second level of PPE when the RTC score is ≥4 – especially when AGP is needed during the COVID-19 outbreak.
Although hand hygiene is considered a standard requirement in dental practice, studies have shown low hand-hygiene compliance (35%–56%) among dental health workers, thus hand hygiene was also included in the checklist,,, followed by wearing gloves, which should be worn at all times. The checklist also includes patient's hand hygiene to minimize the risk of surface area contamination in the dental clinic and possible cross-contamination.
Evidence regarding the effectiveness of preoperative use of antiseptic mouth rinse is controversial. On one hand, several studies suggested the use of a 0.2% chlorhexidine gluconate mouthwash to decrease oral microbes before AGP, especially when a rubber dam cannot be used.,, On the other hand, few studies stated that the use of a preprocedural chlorhexidine gluconate mouth rinse is ineffective in reducing bacterial contamination during AGP. Other studies have shown that a 0.2% povidone-iodine mouth rinse is effective in reducing viruses, including SARS-CoV and MERS-CoV.,, Ather et al. recommended using povidone-iodine mouth rinse before dental emergencies during the COVID-19 pandemic.
Dentists should minimize the use of AGPs during the pandemic and if needed, a rubber dam along with AGPs can be used as presented in the checklist. Studies strongly recommended the use of rubber dam together with high-volume suction as it significantly minimizes aerosols by >70%., For a dental patient whose RTC score is ≥4 and requires AGPs for emergency reasons, it is recommended that the treatment takes place in a negative-pressure room in the dental practice or medical high-efficiency particulate air filter/airborne infection isolation room for the duration of the public health crisis. Regarding AGP, Baumann et al. stated that airborne aerosols could remain in the air from 30 min up to 2 h. van Doremalen et al. have shown that SARS-CoV-2 survived up to 3 h in aerosols and remained viable for 3 days on inanimate surfaces. Hence, a 3-h time lapse is suggested between patients with an RTC score >4 for maximum precaution. Two hours is recommended before the next use of dental clinic when AGP is performed on patients with an RTC score <4, whereas only a 30-min time lapse is necessary before the next use of dental clinic when non-AGP procedures are performed on patients with an RTC score <4.
| Conclusion|| |
Because dental health-care workers are considered a part of the “very high exposure risk” category during COVID-19, they need to take proper precautions to protect themselves and prevent cross-contamination. Thus, having a written reminder in the form of a checklist to recall the important and new nonroutine steps could be helpful. This will improve the safety of dental practice in this critical time during the COVID-19 pandemic. Furthermore, we recommend that dental health-care providers receive good training to be able to recall the checklist steps. It is recommended that dental clinics have those steps printed, laminated, and placed in an accessible visible place to support the implementation process.
