Guidelines for dental care provision during the COVID-19 pandemic

Implications of the COVID-19 Pandemic on the Mental Health and Professional Psychomotor Skills of Dental Students

Purpose

To estimate dental students’ self-perception of mental well-being (MWB) and its effects on their clinical psychomotor skills (CPS) once they (or their family members) get infected with COVID-19.

Materials and Methods

This is a cross-sectional (n =268) study from a public dental college in Riyadh. We collected data on MWB and CPS. An 18-item online survey was used to collect the responses from the participants. The inter-rater reliability for the finalised survey came out to be 0.86.

Results

The participants (54.3%) who were infected with COVID-19 recorded that their CPS were significantly affected (almost 4 times higher) as compared to others (OR= 4.02; P=0.0004). However, 42.2% reported infection control measures at clinics resulted in bringing significant (OR=2.22, P=0.04) psychological upsets, for those who were infected with COVID-19. Participants (45.1%) also reported that they have difficulty in recalling old memories or information due to the COVID-19 pandemic; among them, 46.7% were the ones who (and/or any family member) were exposed to COVID-19.

Conclusion

The study spotlighted the extent of dental students’ MWB and its significant effect on their CPS once (themselves or a family member) infected with COVID-19. Moreover, levels of infection control measures at clinics resulted in psychological upsets for dental students.

Clinical Significance

The issue is fundamental as participants enter the clinical workforce and face the ever-increasing demands of dental practice.

Safety protocols for dental care during the COVID-19 pandemic: the experience of a Brazilian hospital service

The coronavirus disease (COVID-19) has been prioritized in relation to other illnesses considered critical, such as cancer, cardiovascular diseases/stroke, diabetes, and autoimmune diseases. The management of patients with these diseases involves dental care to reduce systemic complications caused by odontogenic infections, and/or to treat oral manifestations of systemic comorbidities. In this regard, the dental care of these individuals must be guaranteed during the pandemic. Although a high risk of exposure to and catching of COVID-19 is expected to befall dental professionals, biosafety guidelines reduce the likelihood of infection. Thus, the current scenario poses challenges, and offers decision-making approaches and tools that facilitate the management of individuals with oral manifestations of chronic and/or critical diseases, using hospital-based services. This article presents an overview for hospital service providers who are at the forefront of COVID-19 care, including a secure protocol, and clinical guidelines based on the experience of the Hospital das Clínicas in Belo Horizonte, a public referral service, supported by the Brazilian National Health System.

COVID-19 pandemic and dental practice in Ghana

With the advent of the COVID-19 pandemic, healthcare systems and their provision of care has globally been challenged, including the delivery of Oral healthcare. In Ghana, it has become imperative that healthcare delivery including the practice of Dentistry and its sub-specialties be re-oriented in our peculiar setting to ensure minimal risk of spread of the infection. This article discusses the impact of COVID-19 on the practice of Dentistry in the country.

Challenges for dental professionals during COVID-19 pandemic: Are we prepared?

BACKGROUND

With the emerging knowledge and understanding of novel coronavirus infection, dentists must be capable of resuming their practice with necessary precautions in near future; hence, the aim of the present study was to evaluate the knowledge, attitude, and practices along with felt challenges by the dentists concerning practicing dentistry during pandemic in India.

MATERIALS AND METHODS

An online cross-sectional questionnaire study was conducted on the dental practitioners of Uttarakhand, India. The dentists were approached by obtaining their E-mail address from the heads of dental institutions or dental association branches in the state. The knowledge, attitude, and practices along with apparent challenges of practicing during pandemic were assessed using closed-ended questionnaire. The relationship between the mean scores and demographic variables was determined using Student's unpaired t-test by keeping the significance level below 0.05.

RESULTS

Out of 759 respondents, a total of 458 respondents were male (60%), whereas 301 (40%) were female. The mean knowledge scores were higher in females (11.06 ± 2.12) compared to males (9.72 ± 4.53), which was statistically significant (P < 0.05). The mean practice score was lower in males (17.49 ± 6.47) compared to females (19.26 ± 6.69) and likewise lower scores were seen in graduates compared to specialists and these differences were again statistically significant (P < 0.05). Majority of the study participants felt that following various safety guidelines were not feasible (96.97%) and too expensive (96.44%) and considered them as a challenge.

CONCLUSION

It is imperative that dentists should be fully prepared before resuming their services and reach the right kind of awareness to limit the spread of the disease.

Dental practice closure during the first wave of COVID-19 and associated professional, practice and structural determinants: a multi-country survey

BACKGROUND

The coronavirus outbreak (COVID-19) in China has influenced every aspect of life worldwide. Given the unique characteristics of the dental setting, the risk of cross-infection between dental practitioners and patients is high in the absence of adequate protective measures, and dentists may develop severe anxiety in relation to the current pandemic. The limited provision of services and widespread closure of dental practices have raised concerns among dental professionals about the financial impact. The present study assessed the frequency of dental practice closure during the pandemic's first wave in several countries and whether closures and their associated factors differ between the private and non-private sectors.

METHODS

An electronic cross-sectional survey questionnaire was sent to dentists in several countries, from April to May 2020. The survey assessed professional, practice related and country-level structural factors elucidating the reason for practice closure. Multilevel logistic regression was used to assess the association between practice closure and these factors, and differences were evaluated by sector type.

RESULTS

Dentists from 29 countries (n = 3243) participated in this study. Most of the participants (75.9%) reported practice closure with significantly higher percentage in the private sector than the non-private sector. Greater pandemic-related fears were associated with a significantly higher likelihood of practice closure in the private (odds ratio [OR] = 1.54, 95% confidence interval [CI] 1.24, 1.92) and non-private (OR = 1.38, 95% CI 1.04, 1.82) sectors. Dentists in non-private rural areas (OR = 0.58, 95% CI 0.42, 0.81), and those in hospitals (overall OR = 0.60, 95% CI 0.36, 0.99) reported a low likelihood of closure. A high likelihood of closure was reported by dentists in the academia (OR = 2.13, 95% CI 1.23, 3.71). More hospital beds at the country-level were associated with a lower likelihood of closure in the non-private sector (OR = 0.65, 95% CI 0.46, 0.91). Private- sector dentists in high- income countries (HICs) reported fewer closures than those in non-HICs (OR = 0.55, 95% CI 0.15, 1.93).

CONCLUSIONS

Most dentists reported practice closure because of COVID-19, and greater impacts were reported in the private sector than in the non-private sector. Closure was associated with professional, practice, and country-levels factors.

Historical Evolution and Filtering Characteristics of Masks and Respirators in Dentistry in the Context of COVID-19: A Literature Review

OBJECTIVES

At present, it is very important to identify the available literature regarding the use of masks and respirators by analyzing their historical evolution in the medical field. In addition, consideration should be given to the major filtering characteristics of those most used due to the current SARS-CoV-2 pandemic. Therefore, the purpose of this literature review is to describe the qualitative evolution that facemasks and respirators have undergone along with their different characteristics.

MATERIALS AND METHODS

This literature review was conducted between September and December 2020. Articles were identified from PubMed Central, Scopus, and Web of Science. The following keywords were used: "COVID-19," "dentistry," and "masks." These MeSH terms were combined with the Boolean operators "AND" and "OR."

RESULTS

We found 36 articles in PubMed Central, 21 in Scopus, and 17 in Web of Science, which included reviews, clinical, descriptive, and experimental trials.

CONCLUSION

The emergence of new pathogens leads to continuous improvement in masks and respirators. It was determined that for the dental field, respirators with filtration characteristics greater than 95%, such as FFP3, N100, N95, and KN95, are indicated in addition to their decontamination and reuse processes.

Uncertainties around COVID-19 from the perspectives of oral health care workers during the first wave of SARS-CoV-2 infections in British Columbia, Canada

Background

The first wave of COVID-19 infections caused disturbances in all aspects of personal and professional lives. The aim of this study was to explore the ways in which that first wave of novel coronavirus infections resulted in uncertainties, as experienced by members of the oral health care workforce in British Columbia, Canada.

Methods

This qualitative inquiry purposefully recruited frontline oral health care workers, including dentists, dental hygienists, certified dental assistants, and administrative staff, via remote semi-structured interviews between April 20 and May 4, 2020. Coding, categories, and themes were inductively assigned.

Results

A total of 45 interviews, lasting between 39 and 74 minutes each, were conducted involving 18 dentists (6 females), 12 dental hygienists (11 females), 6 certified dental assistants (all females), and 9 administrators/front-desk staff (7 females). Fifty-one hours of audio recordings and more than 650 single-spaced pages of transcripts were produced. Five main themes emerged pertaining to uncertainties surrounding COVID-19, patient care, personal lives and infectiousness, concern for the future, and variations among different pandemics. Certitudes were less evident, but surfaced mostly when considering a potential new normal resulting from the pandemic.

Conclusion

Participants indicated that the uncertainties they felt were dependent upon what is known, and unknown, about the pandemic and the provision of oral health care during the first wave of infections. Future studies are needed to include the viewpoints of oral health care workers from other provinces, as well the perceptions of patients who received oral health care during the height of the first wave of the pandemic.

Saliva: What Dental Practitioners Should Know about the Role of This Biofluid in the Transmission and Diagnostic of SARS-CoV-2

A novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak has become a global ongoing pandemic. This pandemic represents a great work risk for all health professionals, it includes dental professionals who are in constant contact with saliva, which represents one of the main routes of transmission of the disease. This is due to the fact that a wide variety of oral tissues and cells are susceptible to infection by SARS-CoV-2 and that they express the ACE2 receptor, which is the main route of entry of the virus into cells, as well as the proteins TMPRSS and furin that contributes to the binding of the virus to the host cells. According to recent studies, some of the oral cells most susceptible to infection by SARS-CoV-2 are the epithelial cells of the salivary glands. This explains the presence of the virus in the saliva of infected patients and provides scientific evidence that supports the use of saliva as a biofluid that offers the opportunity to develop new detection and diagnostic techniques. This is because saliva is much easier to collect compared to nasopharyngeal swab. However, the presence of the virus in saliva, also represents a great source of transmission, since the main form of infection is through microscopic drops that are generated when infected people cough or sneeze. Likewise, health professionals, such as dentists are exposed to contagion through saliva. The objective of this review article is to provide a perspective on the main cells and tissues that can be affected by the virus, the risk of contagion that the presence of the virus in saliva represents for dentists; and the new techniques developed from saliva samples for the diagnosis and surveillance of SARS-CoV-2 infection. This review is expected to contribute to the knowledge of oral health professionals about the risk of saliva in the spread of SARS-CoV-2, but also its advantages as a diagnostic tool for pandemic control. In conclusion, the authors can mention that information that provides more scientific evidence of the mechanisms of infection of the coronavirus in oral cells and tissues is being published continually. This also explains the presence of the virus in the saliva of infected people and the risk of contagion that this means. It also provides scientific evidence of the use of saliva as a biofluid for the detection, diagnosis, monitoring, and control of the spread of the virus.

Infection control in dental health care during and after the SARS-CoV-2 outbreak

COVID-19 is an emerging infectious disease caused by the widespread transmission of the coronavirus SARS-CoV-2. Some of those infected become seriously ill. Others do not show any symptoms, but can still contribute to transmission of the virus. SARS-CoV-2 is excreted in the oral cavity and can be spread via aerosols. Aerosol generating procedures in dental health care can increase the risk of transmission of the virus. Due to the risk of infection of both dental healthcare workers and patients, additional infection control measures for all patients are strongly recommended when providing dental health care. Consideration should be given to which infection control measures are necessary when providing care in both the current situation and in the future.

Knowledge, stress levels, and clinical practice modifications of Turkish dentists due to COVID-19: a survey study

Dentists are exposed to the highest risk of occupational respiratory and droplet infections by working face-to-face with patients. The aim of this study was to investigate the knowledge of symptoms and modes of transmission of COVID-19, stress levels and clinical practice modifications of Turkish dentists during the COVID-19 pandemic. An online survey (15 questions) was sent to Turkish dentists from May 5 to 12 May, 2020. The survey comprised questions about dentists' demographic characteristics, their knowledge about COVID-19, stress levels and the measures taken in dental clinics against COVID-19. This study included a total of 1,095 Turkish dentists. The data were expressed as frequency with percentage values for overall variables. Dentists were most familiar with high fever among the symptoms of COVID-19 (99.4%) and 99.2% of them reported that COVID-19 was transmitted with eye, mouth and nasal mucosa contact on surfaces contaminated with the droplets of infected persons. While the stress levels of females were higher than males, the stress levels of dentists with more than 20 years of professional experience were found to be lower. Regarding the precautions to be taken as a preventive measure when working again, 86.6% of the dentists took precautions by increasing daily patient care intervals and only 38.4% of the dentists wore an N95 mask. During this pandemic, knowing the conditions about when the treatments can be applied and the precautions to be taken will shed light on dentistry staff. Current recommendations of national authorities about the coronavirus should be followed.

An Untested and Uncooperative Pediatric Patient Undergoing a Dental Procedure Using a Negative Airflow Tent During the Coronavirus Disease 2019 Pandemic: A Case Report

The coronavirus disease 2019 (COVID-19) pandemic prompted the creation of novel techniques to protect patients and health care providers. Simulations showed that disposable oxygen face tents act as a physical barrier and can be repurposed as a negative airflow tent. This case study presents a pediatric patient requiring dental surgery, ineligible for preoperative testing for COVID-19 due to developmental delay and aggression. Precautionary measures were taken by means of full personal protective equipment (PPE) and negative airflow tent. The tent added additional protection and is a promising new technique that is disposable, widely available, and offers full access to proceduralists.

Impact of COVID-19 Pandemic on Healthcare Professionals and Oral Care Operational Services: A Systemic Review

The unprecedented climate of the COVID-19 pandemic has some restrictions on oral care operational services, which heavily impacted the delivery of aerosol generating procedures (AGPs). This led the health authorities to set up guidelines and policies that should be followed to minimize the virus spread and ensure safe and effective dental care delivery. This systemic review aimed to evaluate the current guidelines and strategies in providing safe dental services and ensuring efficacy of the current universal personal preventive and protective measures, as well the impact that this outbreak might have on practicing the dental profession in full scope. The review focus questions were as follows: are the current guidelines and measures in literature mitigated enough to ensure safe and effective oral care delivery to patients during the COVID-19 pandemic? Is it possible to highlight the essential and fundamental cross-infection control measures and policies? Twenty articles were chosen out of 180,248 after the inclusion and exclusion criteria were applied in the period between January 1st and August 1st 2020. Our results highlighted effective safety measures that can be implanted in protecting healthcare professionals and patients and ensuring optimal dental care delivery in a safe and healthy environment, taking into consideration the risk assessment and management of AGPs. In conclusion, informative updated standardized policies and protocols are required when more knowledge on the virus behavior keeps evolving. Moreover, there is a need for evidence-based protective measures to be modified on a regular basis to be followed, until a safe vaccine is produced.

Global concerns of dental and oral health workers during COVID-19 outbreak: a scope study on the concerns and the coping strategies

BACKGROUND

Dental and oral health workers have direct contact with respiratory aerosols of patients during procedures. This study aimed to determine the main concerns of dental and oral health workers globally during COVID-19 outbreaks and the coping strategies that help the resilience of dental and oral healthcare system.

METHODS

This scoping study was conducted in August 2020. After adjusting the search strategy, a systematic search of five databases (PubMed, ISI Web of Science, Scopus, ProQuest and EMBASE) was conducted. Data was extracted using Microsoft Excel and the contents of retrieved articles were analysed through a qualitative thematic analysis applying MAX QDA₁₀.

RESULTS

Most articles were either editorial/letters to the editor/commentary formats (34%), or literature reviews (26%). About half of the articles belonged to three countries of Italy, China and the USA (each 16% and totally 48%). Thematic analysis of included papers led to the identification of four main global concerns and 19 sub-concerns. Economic, ethical, social and professional concerns are among dental and oral health concerns. Other results indicate on three main themes and 13 sub-themes as the coping strategies including patient management, infection control and virtual strategies.

CONCLUSION

Dental and oral health care workers have many concerns relating to COVID-19 including economic, ethical, social and professional factors. Resolution of concerns may involve enhancing coping strategies relating to patient management and infection control strategies as well as using new technologies for virtual contact with the patient without any risk of infection.

Is there scientific evidence of the mouthwashes effectiveness in reducing viral load in Covid-19? A systematic review

BACKGROUND

The aim of this research is to verify whether there is evidence in the literature regarding the decrease in viral load present in saliva after using three types of mouthwashes.

MATERIAL AND METHODS

Clinical and/or in vitro experimental studies that have used mouthwashes as a form of intervention to reduce the viral load in saliva were included. Combinations of words and appropriate truncations were adapted for each of the seven selected electronic bases including grey literature.

RESULTS

The selection of articles was carried out in two phases by two independent reviewers. After removing duplicate articles, 1245 references were maintained, and 2 articles were included in the Systematic Review. Both studies were performed in vitro and tested the virucidal action of the PVP-I solution for mouthwash at two different concentrations, 1% without dilution and 7% with 1:30 dilution, on the SARS-CoV and MERS-CoV viruses. Both showed a viral reduction of ≥ 99.99% with 15 s exposure.

CONCLUSIONS

Based on the evidence currently available in the literature, PVP-I, at concentrations of 1 and 7%, appears to be the most effective mouthwash for reducing the viral load of COVID-19 present in human saliva. However, the guidelines for dental care refer to the use of hydrogen peroxide but there is insufficient scientific evidence to support this recommendation. Key words:COVID-19, Coronavirus, Mouthwash, Chlorhexidine, Hydrogen Peroxide, PVP-I.

Antiviral Activity of Reagents in Mouth Rinses against SARS-CoV-2

The oral cavity, an essential part of the upper aerodigestive tract, is believed to play an important role in the pathogenicity and transmission of SARS-CoV-2. The identification of targeted antiviral mouth rinses to reduce salivary viral load would contribute to reducing the COVID-19 pandemic. While awaiting the results of significant clinical studies, which to date do not exist, the commercial availability of mouth rinses leads us to search among them for reagents that would have specific antiviral properties with respect to SARS-CoV-2. The challenges facing this target were examined for 7 reagents found in commercially available mouth rinses and listed on the ClinicalTrials.gov website: povidone-iodine, chlorhexidine, hydrogen peroxide, cyclodextrin, Citrox, cetylpyridinium chloride, and essential oils. Because SARS-CoV-2 is an enveloped virus, many reagents target the outer lipid membrane. Moreover, some of them can act on the capsid by denaturing proteins. Until now, there has been no scientific evidence to recommend mouth rinses with an anti-SARS-CoV-2 effect to control the viral load in the oral cavity. This critical review indicates that current knowledge of these reagents would likely improve trends in salivary viral load status. This finding is a strong sign to encourage clinical research for which quality protocols are already available in the literature.

The Debate: What Are Aerosol-Generating Procedures in Dentistry? A Rapid Review

Introduction:

This article aims to review the current national and international dental guidance produced during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic to identify the level of consensus on aerosol-generating dental procedures (AGDPs). The outcomes intend to encourage increased collaboration with respect to dental guidelines in relation to the SARS-CoV-2 pandemic, as well as to improve decision making and safety for dental patients and staff.

Methods:

This rapid review was conducted by 2 authors (MKV and KD), with the support of a third author (SD), to assess current guidelines related to dental AGDPs. This streamlined review approach allowed synthesis of data in an efficient manner in the rapidly evolving environment associated with the SARS-CoV-2 pandemic.

Results:

The findings identified 1) a lack of consistency in reporting which procedures were deemed an AGDP; 2) that high-speed handpieces, air-water syringes, and mechanical scalers were consistently considered high-risk AGDPs; 3) a lack of consensus on the risk of coronavirus disease 2019 (COVID-19) transmission with the use of slow-speed handpieces; 4) a general agreement, when described, that rubber dam and high-volume evacuation can significantly reduce aerosol production; and 5) a lack of consistency in reporting whether procedures constitute a low, moderate, or high risk of COVID-19 transmission. The findings are discussed in relation to the guidance and future recommendations.

Conclusion:

It is recommended that future published guidance should indicate the risk stratification (low/moderate/high) of each procedure/exposure in a standardized international approach.

Knowledge Transfer Statement:

The results of this rapid review can be used by clinicians to increase their awareness of international guidance on aerosol-generating procedures in dentistry. It will also encourage those publishing future guidance to provide an internationally standardized, risk-stratified approach to describing aerosol-generating procedures. Currently, it allows clinicians to consider aerosol-generating procedures as a risk spectrum.

INTRODUCTION

The management of endodontic emergencies has been particularly challenging during the coronavirus disease 2019 (COVID-19) outbreak because of the possible generation of airborne particles and aerosols. The aim of this report was to contribute to the practice of endodontics by proposing a general protocol for the management of emergencies showing the rationale for remote diagnosis, clinical procedures, and the use of personal protective equipment and barriers at the dental office during the COVID-19 outbreak.

METHODS

A review of the literature was conducted up to May 2020 on relevant institutional sites, aiming to retrieve the best updated evidence. The reporting considered the Reporting Tool for Practice Guidelines in Health Care statement.

RESULTS

Recommendations from Cochrane Oral Health, the American Dental Association, and the Centers for Disease Control and Prevention were included along with the American Association of Endodontists resources and scientific articles that addressed the issue.

CONCLUSIONS

The proposed protocol could contribute to the management of endodontic emergencies at the dental office during the COVID-19 outbreak.

Evaluating the Influence of COVID-19 Among Dental Practitioners After Lockdown

Clinical activities at dental premises after the COVID-19 lockdown period or post-COVID-19 are likely to be a challenge for all practicing dentists. To assess the impact of the COVID-19 pandemic on dentists and change in dental practice following lockdown, a total of 1150 participants were approached through online survey forms registered on www.surveys.google. A link containing details of the questionnaire and a consent form was sent to dentists through emails and social media forums. The questionnaire included 3 domains comprising of seventeen questions. The first section focused on demographics. The second section inquired about the change in dental practice, that is, clinical hours, use of PPE, type of treatment, and patient flow. The third section investigated the impact of COVID-19 on dentistry. Means, standard deviation, and percentages were calculated using descriptive statistics. Chi-square was used to find an association between different variables. The response rate was 87%. Demographic factors revealed participants aged from 20.45 to 40.55 years. The data showed around 89.6% (896) of dentists have altered their clinical working hours post lockdown and, approximately, 59.7% (597) of dentists provided only emergency treatments. 88.1% (881) of the dentists wore PPE during dental procedures. Overall, a huge negative impact of the COVID-19 pandemic was observed among practicing dentists in terms of the dental supply chain, cost, and availability of dental equipment, treatment cost, and bill payments.COVID-19 pandemic compromised dental care. Though dentists were taking precautionary measures and have changed their practice according to the guidelines provided by the ADA and World Health Organization, they were still experiencing monetary loss due to decrease patient influx post lockdown.

Coronavirus Disease-19 and Dentistry: A Review

Novel coronavirus (nCoV) is a novel form of virus with a new strain identified recently in humans. Common clinical signs and symptoms primarily consist of fever, cough, and breathing difficulties. In severe cases, it can results in pneumonia, severe acute respiratory syndrome, kidney failure, and even death. It is important to follow all infection control measures in prevention of the nCoV from spreading and controlling the epidemic situation. The risk of cross infection can be high between dental practitioners and patients due to the features of dental clinical settings. Here, we are summarizing the nCoV related information and infection control measures to be followed in dental practice.

Polymeric Iodophors: Preparation, Properties, and Biomedical Applications

The review summarizes the data on the main chemical and physiological properties of iodine and its capability of complexation with natural and synthetic polymers. Iodine is the best known antiseptic used to prevent and treat microbial infections. Its unique capability of complexation with certain polymers opens wide opportunities for targeted and prolonged delivery to target organs. Polymeric complexes with iodine have another color, other morphology, a higher electrical conductivity, and higher biological activity as compared with initial polymers. The formation of and ions is associated with iodine-polymer complexation. Iodine-containing biocompatible adhesive controlled-release formulations are designed as part of research into iodine-polymer complexes. The field is promising in terms of treating certain diseases because tolerance to iodine compounds does not usually develop in microbial cells.

A Pan-Canadian narrative review on the protocols for reopening dental services during the COVID-19 pandemic

The current coronavirus disease 2019 (COVID-19) pandemic is impacting the way in which dental services are provided. The aim of this narrative review was twofold: to summarize key areas from the Canadian protocols available for the reopening and restructuring of dental services across the country and to critically review these protocols based on existing evidence. A narrative review of the existing Canadian protocols, written in English and French, was undertaken between April 15 and July 13, 2020. The protocols were obtained by searching through regulatory bodies and websites from professional organizations, and from personal contacts through academic institutions and policy leaders. The data extraction form focused only on protocols related to dentistry, and the information was compiled by a hired assistant. Content was categorized via group discussions with the research team on eight areas: office management and procedures, patient and staff screening, treatment procedures, office layout, risk reduction, personal protective equipment, supporting information, and length and readability. Thirteen protocols were identified and offered substantial variation in the level of details provided. All but two protocols specified proper donning/doffing of personal protective equipment, while all protocols recommended daily monitoring of COVID-19 related signs and symptoms in staff and patients. They varied in terms of recommended mask types, eye and face shield protection, and head coverings. While all protocols aimed at restructuring emergency dental services, their recommendations were often not based on the published evidence. This narrative review summarized key areas from 13 provincial and territorial protocols in Canada to help oral health care providers plan the reopening of their services. The information conveyed across all documents was clear, but variance highlights the need for a coordinated effort to develop an evidence-based document for dental practitioners.

Association of Personal Protective Equipment with De Novo Headaches in Frontline Healthcare Workers during COVID-19 Pandemic: A Cross-Sectional Study

OBJECTIVES

 This study aimed to determine the association of personal protective equipment (PPE) usage with new-onset headaches and exacerbation of pre-existing headache disorders among healthcare workers at the frontlines during coronavirus disease 2019 (COVID-19) pandemic.

MATERIALS AND METHODS

 A descriptive cross-sectional survey was conducted across Pakistan in June-July 2020. The study was approved by Ethical Committee, Armed Forces Institute of Dentistry, Rawalpindi (IRB form no.905/Trg-ABP 1K2). A qualitative questionnaire was developed and was shared via different social networks. The questionnaire was closed when 241 responses were received.

STATISTICAL ANALYSIS

 Descriptive analysis was performed on demographic data. Chi-squared analysis was performed between demographic data and PPE-usage patterns among participants with or without de novo headaches. Univariable and multivariable logistic regression models were used to compare variables with the development of new-onset headaches. Chi-squared test was also performed between demographic data and other factors that may be causing new-onset headaches. A p-value < 0.05 was considered significant.

RESULTS

 A total of 241 healthcare workers participated, of which 68 participants (28.2%) reported de novo headaches since the start of the pandemic. Incidence of pre-existing headaches (odds ratio [OR] = 1.91; 95% confidence interval [CI]: 0.99-0.37; p = 0.049) was associated with new-onset headaches. Post hoc multivariable logistic regression analysis stated that incidence of pre-existing headaches (OR = 1.88; 95% CI: 0.94-3.78; p = 0.75) and age (OR = 2.21; 95% CI: 0.47-10.33; p = 0.36) was independently associated with new-onset PPE-induced headaches but was not statistically significant. Chi-squared analysis showed a statistically significant relationship between other factors (sleep deprivation, emotional stress, etc.) and department of activity, gender, and occupation (p < 0.05).

CONCLUSION

 Healthcare workers with previous history of pre-existing headaches were found to be more susceptible to PPE-induced headaches during COVID-19 pandemic. However, age and the department where the healthcare workers performed may also be risk factors.

COVID-19 and Oral Surgery: A narrative review of preoperative mouth rinses

OBJECTIVE

To provide a narrative review of the preprocedural mouth rinse protocols suggested for oral surgery in order to contrast the presence of SARS-CoV-2 in aerosol.

SOURCES AND METHODS

Electronic searches were performed in medical databases PubMed, Medline, CINAHN and Scopus to identify relevant studies published up until the third week of April 2020. This research was supplemented by exploration through a web-based search engine as well as a manual search for international and national guidelines. Studies and protocols which suggested preoperative mouth rinsing as a recommended measure during the COVID-19 outbreak were included. Given the small number of studies, a narrative literature review was conducted. In total, 15 references (11 articles and 4 guidelines) were considered relevant and were critically analysed.

CONCLUSION

The findings show a high heterogeneity in the protocols suggested. Further research is required to better understand the viral features and epidemiologic characteristics of this new virus and to test the efficacy of commonly used antiseptics against SARS-CoV-2 in future clinical trials. However, the use of chlorhexidine, hydrogen peroxide, PVP-I and cetylpyridinium chloride in contrasting the spread of Covid-19 is described as advisable and substantial in different publications.

Pivoting Dental Practice Management during the COVID-19 Pandemic-A Systematic Review

Background and Objectives: The aims of this systematic review were to identify additional infection control measures implemented in dental practice globally to prevent cross-infection and evaluate the psychological impacts of the pandemic among dental professionals. Materials and Methods: A sequential systematic literature search was conducted from December 2019 to 30 April 2020 through PubMed, CINAHL, Scopus, Google Scholar, Embase, and Web of Science databases. The search yielded the following results: "COVID-19" (n = 12,137), "Novel corona virus" (n = 63), "COVID-19 and dentistry" (n = 46), "COVID-19 and oral health" (n = 41), "Novel Corona virus and Dentistry" (n = 0), "dental health and Novel Coronavirus" (n = 26), and "dental practice and Novel Coronavirus" (n = 6). Results: After a careful review and eliminating articles based on inclusion and exclusion criteria, the final review included 13 articles. Management of infection control is discussed extensively in the literature and remains the main theme of many Coronavirus Disease 2019 (COVID-19) articles on dentistry. Telephone triage using a questionnaire, hand hygiene, personal protective equipment (PPE) for clinical and nonclinical staff, a preprocedural mouth rinse, and aerosol management have been discussed and implemented in few countries. Three studies recommended that elective treatments for patients with a temperature of >100.4 F or 38 °C should be postponed or performed in an airborne infection isolation room (AIIR) or negative-pressure room. Limiting the number of patients in the waiting area, the removal of shared objects, proper ventilation, and physical distancing were highly recommended. Psychological distress among dental professionals in relation to existing medical conditions and self-efficacy has been discussed. Conclusions: Although the COVID-19 pandemic has had a substantial impact on the dental profession worldwide, our review highlights many practice management approaches to adopt the new norm. More research highlighting evidence-based safety practices and multisectoral collaboration is required to help dental professionals make informed decisions and make the profession safe, both for the patient and dental professionals.

Head and neck cancer therapy-related oral manifestation management in the COVID-19 pandemic: a critical review

With the onset of the new coronavirus disease (COVID-19) pandemic, the dental treatment of patients at risk of infection has become quite challenging. In view of this, patients with head and neck cancer may present with oral complications due to anticancer therapy, making dental assistance necessary. Thus, the objective of the study was to review the literature and critically discuss important concerns about the treatment of patients with head and neck cancer during the COVID-19 pandemic. Because dental professionals are in close contact with the main viral transmission routes, this study presents recommendations for management and protection during clinical dental care. The main characteristics and transmission routes of COVID-19 are also discussed. Dental professionals should control pain and the side effects of antineoplastic treatment and use preventive measures for infection control. During this pandemic, patients with head and neck cancer should not undergo elective procedures, even if they do not have symptoms or a history of COVID-19; therefore, in asymptomatic or painless cases, only preventive actions are recommended. In symptomatic or painful cases, precautions for safe interventional treatments must be implemented by following the hygiene measures recommended by health agencies and using personal protective equipment. During health crises, new protocols emerge for cancer treatment, and professionals must act with greater attention toward biosafety and updated knowledge. It is important to offer adequate individualized treatment based on the recommendations of preventative and interventional treatments so that patients can face this difficult period with optimized quality of life.

The impact of COVID-19 pandemic on patients receiving orthodontic treatment: An online questionnaire cross-sectional study

Background

The spread of Coronavirus Disease 2019 (COVID-19) has led to a major public health issue; most dental clinics were closed and millions of orthodontic patients were unable to complete their treatment. This study aimed to assess the challenges faced by patients receiving orthodontic treatment and their preferred solutions to overcoming these challenges during this pandemic.

Methods

An online questionnaire was developed and sent to patients receiving orthodontic treatment at a public or private clinic.

Results

A total of 388 responses were analyzed: mean age 20.4 ± 4 years, 75% (291) female, and 58% (226) received their treatment at a public clinic. Of all participants, 27.3% (106) were still unable to attend their appointments and 69% (244) stated that closing of the clinic was the main reason for missing their appointments. Depending on their type of appliance, the patients faced different problems and chose multiple ways to deal with them. Most participants had fixed appliances, 84% (327), and only 21% (64) of them stated that they had no problem compared with 39% (11) and 36% (8) for removable appliance and clear aligner groups, respectively.

Conclusion

The COVID-19 pandemic has had a significant impact on orthodontic treatments. Almost every orthodontic patient had to stop attending their appointments, which put them in complicated situations and in fear of delayed treatment. Patients from a public clinic and patients with fixed appliances reported more problems than others. More attention should be giving to teleorthodontics; also orthodontists should prepare their patients to deal with some of the problems related to their appliances when possible.

COVID-19 Perceptional Disparity Among Dental Healthcare Personnel at King Faisal University: Applying Health Belief Model

Objectives  In Saudi Arabia, more than 100, 000 cases of COVID-19 have been reported, and more than 4,000 in Al Hofuf to date. Dental healthcare personnel are at a higher risk of COVID-19 due to their exposure to saliva, blood, and aerosol/droplet during their daily practice. Their perceptions of COVID-19 drive their behaviors.

Materials and Methods  A cross-sectional online survey to assess COVID-19 related perceptions and possible disparities between them.

Statistical analysis  Data were analyzed using the Statistical Package for the Social Science, version 23 (IBM SPSS). Descriptive analyses were performed using frequencies and percentages for categorical variables, mean and (± SD) for numerical variables. Bivariate analyses were assessed using t -test and one-way ANOVA, with a 95% confidence interval (CI).

Results  With a response of 75% (150), results showed that there were perceptional disparities: students and technical staff perceived more barriers to preventive measures compared to faculties with a mean difference of (−0.145 SD ± 0.580, p = 0.802, CI −1.29 / 1.00 and −2.433, SD ± 0.94, p = 0.010), respectively. This was also shown in threat perception with a mean difference of (2.525, SE ± 0.917, CI 0.71/4.34, p = 0. 0.007). Students perceived more threat than clerks did with a mean difference of (1.281, SE ± 0.569, CI − 0.16 / 2.41, p = 0.026), while clerks perceived less threat than the technical staff with a mean difference of (−2.790, SE ± 0.860, CI −4.49 /−1.09, p = 0.001).

Conclusions  There was a clear disparity in the perceptions among the different categories of participants. More emphasis on the training and preparedness of the dental healthcare personnel is required.

COVID-19 transmission risk and protective protocols in dentistry: a systematic review

BACKGROUND

Among several potential transmission sources in the spreading of the COVID-19, dental services have received a high volume of attention. Several reports, papers, guidelines, and suggestions have been released on how this infection could be transmitted through dental services and what should be done. This study aimed to review the guidelines in order to develop a practical feasibility protocol for the re-opening of dental clinics and the reorientation of dental services.

METHODS

This study systematically reviewed the published literature and the guidelines of international health care institutions on dentistry and COVID-19. We searched Pubmed, Web of Science, and SCOPUS electronic databases using MESH terms. The recommendations identified were tested with a convenience sample of experienced practitioners, and a practical step-by-step protocol is presented in this paper.

RESULTS

To the date this paper was drafted, 38 articles were found, of which 9 satisfied our inclusion criteria. As all the nine studies were proposed in a general consensus, any elective non-emergency dental care for patients with suspected or known COVID-19 should be postponed for at least 2 weeks during the COVID-19 pandemic. Only urgent treatment of dental diseases can be performed during the COVID-19 outbreak taking into consideration pharmacological management as the first line and contagion-reduced minimally invasive emergency treatment as the secondary and final management.

CONCLUSIONS

While the currently available evidence has not demonstrated a clear and direct relationship between dental treatment or surgery and the possibility of the transmission of COVID-19, there is clearly the potential for transmission. Therefore, following the protective protocols in the COVID-19 crisis is of utmost importance in a dental setting.

Clinical endodontic management during the COVID-19 pandemic: a literature review and clinical recommendations

The spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in millions of confirmed cases and hundreds of thousands of deaths. Despite all efforts to contain the spread of the disease, the number of infections and deaths continue to rise, particularly in some regions. Given its presence in the salivary secretions of affected patients, and the presence of many reported asymptomatic cases that have tested positive for COVID-19, dental professionals, including Endodontists, are at high risk of becoming infected if they do not take appropriate precautions. As of today, there are no predictable treatments or approved vaccines that can protect the public and healthcare professionals from the virus; however, there is speculation that a vaccine might be available sometime in 2021. Until then, general dentists and Endodontist will need to be able to treat emergency patients in order to relieve pressure on emergency clinics in hospitals or local community hubs. In addition, as the pandemic continues, strategies to manage patients will need to evolve from a palliative to a more permanent/definitive treatment approach. In this article, an update on the treatment considerations for dental care in general is provided, as well as a discussion on the available endodontic guidelines reported in the literature. Recommendations on clinical management of endodontic emergencies are proposed.

COVID-19-Orthodontic Care During and After the Pandemic: A Narrative Review

OBJECTIVES

To provide comprehensive information regarding the implications of the coronavirus disease 2019 (COVID-19), mode of transmission of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), and its effects on orthodontic care during the pandemic and post-pandemic outbreak of the disease, based on currently available literature and information.

MATERIALS AND METHODS

A comprehensive research for studies that focused on the COVID-19 pandemic and orthodontic care up to August 18, 2020, with no language restriction. The databases included PubMed, MEDLINE, Scopus, Google Scholar, and COVID-19 Open Research Dataset (CORD-19) 2020. The research was focused on presenting symptoms, disease transmission, infection control, orthodontic care, and financial implications affecting the delivery of orthodontic treatment. The research also included reports from major health policy regulatory bodies such as World Health Organization, Centers for Disease Control and Prevention, European Centre for Disease Control and Prevention, and major international dental and orthodontic societies and associations. The peer-reviewed publications and guidelines from the health regulatory authorities were given priority.

RESULTS

The latest information on the SARS-CoV-2 virus effects and orthodontic implications were arranged sequentially. The SARS-CoV-2 virus mode of transmission and its prevention were emphasized to keep the orthodontic and dental operatory safe for continuing practice.

CONCLUSION

The COVID-19 outbreak has changed the way orthodontics is practiced. Strict infection control, near-zero aerosol production, and minimal touch dentistry are the keys to prevent contamination of orthodontic operatory. During the pandemic, only emergency orthodontic procedures could be extended to the orthodontic patient while adhering to all the regulatory guidelines. Fortunately, to date, there is no reported case of cross-transmission of the SARS-CoV-2 virus at the dental setup.

Comprehensive review of guidelines to practice prosthodontic and implant procedures during COVID-19 pandemic

OBJECTIVES

To present a comprehensive review of current literature available on Corona virus disease and dentistry, modifications required in dental and laboratory settings; and recommended disinfection protocols in current scenario. Special emphasis has been given to discuss guidelines for handling different prosthodontic procedures and implications of this pandemic on prosthodontic practice, education and research.

MATERIALS AND METHODS

Relevant literature pertaining to COVID-19 and dentistry was scrutinized on electronic search engines including PubMed, EMBASE and Cochrane. Guidelines given by various organizations, institutions, national and international regulatory bodies and Indian Prosthodontic Society were also consulted to gather information pertaining to the objectives of our review.

RESULTS

and observations: A total of 160 articles including cross-sectional studies, in vitro study, narrative reviews, letters to the editor and opinions were found to be relevant in accordance with our search strategy. Documented literature revealed that Covid-19 pandemic has culminated in serious clinical, financial and psychological implications in the field of dentistry. Certain steps such as adoption of teledentistry, judicious use of protective equipment, use of rubber dams, pre-procedural rinses have been suggested unanimously. However, there is a dearth of evidence-based recommendations in literature. Data regarding consequences of delaying prosthodontic procedures and patients' perspectives is also sparse.

CONCLUSION

The COVID-19 necessitates the need to adopt a balanced approach while treating patients and safeguarding the dental professionals at the same time. Risk-benefit ratio has to be assessed along with stringent following of guidelines and disinfection protocols to combat this unprecedented situation.

Risk for dental healthcare professionals during the COVID-19 global pandemic: An evidence-based assessment

OBJECTIVES

Heightened anxiety among dental healthcare professionals (DHPs) during the COVID-19 pandemic stems from uncertainties about the effectiveness of personal protective equipment (PPE) against dental aerosols and risk levels of asymptomatic patients. Our objective was to assess the risks for DHPs providing dental care during the pandemic based on available scientific evidence.

METHODS

We reviewed the best available evidence and estimated the annualized risk (p=das(1-1-p0p1(1-e)yn) for a DHP during the COVID-19 pandemic based on the following basic parameters: p0, the prevalence of asymptomatic patients in the local population; p1, the probability that a DHP gets infected by an asymptomatic patient; e, the effectiveness of the PPE; s, the probability of becoming symptomatic after getting infected from asymptomatic patient; da, the probability of dying from the disease in age group a; n, number of patients seen per day; and y, number of days worked per year.

RESULTS

With the assumption that DHPs work fulltime and wear a N95 mask, the annualized probability for a DHP to acquire COVID-19 infection in a dental office, become symptomatic, and die from the infection is estimated at 1:13,000 (0.008 %) in a medium sized city in the US at the peak of the pandemic. The risk estimate is highly age-dependent. Risk to DHPs under the age of 70 is negligible when prevalence of asymptomatic cases is low in the local community.

CONCLUSIONS

Risk of COVID-19 transmission in dental office is very low based on available evidence on effectiveness of PPE and prevalence of asymptomatic patients. Face shields and pre-procedure oral rinses may further reduce the risks.

CLINICAL SIGNIFICANCE

DHPs should follow guidelines on pre-appointment protocols and on PPE use during dental treatments to keep the risk low.

COVID-19: Perspectives for the management of dental care and education

The rapid and abrupt transmission pattern of the SARS-CoV-2 unleashed the current COVID-19 pandemic, as recognized by the World Health Organization in March 2020. Considering the high risk of transmission of the virus in dental environments and the specificities in clinical practice, COVID-19 posed immediate challenges for dental care and education. Due to the need to establish infection prevention and control guidance in dental health settings to enable a safe clinical practice, this review aims to list the challenges and perspectives in managing dental care in services and schools. This review employed materials collected from PubMed and the main guidelines and studies on the novel coronavirus to provide an overview of the clinical procedures and decisions made by health care personnel in dental offices and dental schools. We expect the COVID-19 scenario to promote significant changes in clinical practice and dental education; dentists should seek specific and particular regulations for dental practice established by their state or country. Biosafety checklists are strongly recommended for appointments at dental services and face-to-face activities in dental schools.

Managing the Oral Health of Cancer Patients During the COVID-19 Pandemic: Perspective of a Dental Clinic in a Cancer Center

The practice of dentistry has been dramatically altered by the coronavirus disease 2019 (COVID-19) pandemic. Given the close person-to-person contact involved in delivering dental care and treatment procedures that produce aerosols, dental healthcare professionals including dentists, dental assistants and dental hygienists are at high risk of exposure. As a dental clinic in a comprehensive cancer center, we have continued to safely provide medically necessary and urgent/emergent dental care to ensure that patients can adhere to their planned cancer treatment. This was accomplished through timely adaptation of clinical workflows and implementation of practice modification measures in compliance with state, national and federal guidelines to ensure that risk of transmission remained low and the health of both immunocompromised cancer patients and clinical staff remained protected. In this narrative review, we share our experience and measures that were implemented in our clinic to ensure that the oral health needs of cancer patients were met in a timely manner and in a safe environment. Given that the pandemic is still on-going, the impact of our modified oral healthcare delivery model in cancer patients warrants continued monitoring and assessment.

Concerns, perceived impact, and preparedness of oral healthcare workers in their working environment during COVID-19 pandemic

OBJECTIVE

The aim of the study was to evaluate the oral healthcare workers' concerns, perceived impact, and preparedness in COVID-19 pandemic.

METHODS

This cross-sectional study was carried out at 10 different dental hospitals in Pakistan from March to June 2020. A 35 items valid and reliable questionnaire was used to assess the concerns, perceived impact, and preparedness of oral healthcare workers (OHCW) in COVID-19 pandemic. Chi-squared test and logistic regression were used for analysis.

RESULTS

A total of 583 OHCW participated in this study. The odds of having the awareness about the risk of exposure and fear of getting infected, were greater in the clinical than non-clinical OHCW (OR: 52.6; OR: 15.9). For social network concerns, the clinical OHCW were more likely to be concerned about their colleagues (OR: 6.0). The clinical OHCW have greater odds of worrying about telling the family/friends about the risk exposed to (OR: 2.55), being avoided because of the job (OR: 3.20) and more likely to be feeling stressed (OR: 4.31). Less than 50% of the participants felt that their institutions are well prepared and only 12.6% had attended an infection control training session. Most participants practiced self-preparation such as buying masks and disinfection (94.3%, 98.3%).

CONCLUSION

The majority of OHCW felt concerned about their risk of exposure to infection and falling ill from exposure and infecting friends/family. There is a need for training of infection control and PPE and minimizing fear and psychological impact on OHCW should be the priority in any preparedness and planning for combating COVID-19.

COVID-19: Prosthodontic Challenges and Opportunities in Dental Practice

The coronavirus disease (COVID-19) has spread globally. Dentists, dental specialists, dental assistants, dental staff, and patients are potentially at higher risk of COVID-19 infection during dental treatments. The prosthodontic dental treatment procedures may range from low to very high risk of COVID-19. This article presents necessary recommendations regarding the prosthodontic dental treatment procedures with standards of care and infection control.

Palliative dental care: Ignored dimension of dentistry amidst COVID-19 pandemic

Palliative care (PC) represents an approach that encompasses the procedures to relieve pain and distressing symptoms and maintain function as much as possible in the terminally ill patient until death. PC dentistry (PCD) is an approach for providing supportive and palliative dental care in patients with serious life-threatening illness (cancer, chronic heart failure, chronic obstructive pulmonary disease and cognitive impairment). The care is provided at different time points of diseases (i.e., from in-therapy care to survivorship care to end-of-life care). Dentists have a significant role to play in the multidisciplinary team of PC. Oral health problems (ulcers, mucositis, pulpitis and abscess) have a negative impact on general health and quality of life and can be acutely debilitating in these patients. These patients with existing comorbidities are at increased risk of developing oral complications. Furthermore, social isolation can cause an increase in anxiety, hopelessness, psychosocial and existential suffering amongst these patients. It is essential to incorporate PCD in the guidelines of critical dental care during the COVID-19 pandemic to decrease the suffering of these patients by symptom management. Teledentistry can be used with caution to provide at-home care to such patients during the pandemic.

The Coronavirus Disease-19 Infection and the Oral Mucosa

BACKGROUND: The current coronavirus disease (COVID-19) pandemics induced a modification of daily life and clinical practice. Health care workers, particularly dentists and dental hygienists, have been obliged to limit their activity and to establish new operative protocols. AIM: We aimed to discuss an easy protocol for the prevention of cross-infections in dental settings. METHODS: We revised literature data about COVID-19 and oral health to establish how to work safely with dental patients. RESULTS AND CONCLUSION: A few papers are currently available about the effective prevention of COVID-19 during dental procedures. Most of the revised articles report a potential strong effectiveness of povidone-iodine and its safety for both patients and dental professionals.

Pandemic preparedness of dentists against coronavirus disease: A Saudi Arabian experience

Background

Dental offices are among the highest risk for transmission of the COVID-19, having the potential to transmit the virus via routine dental procedures. This cross-sectional study assessed the preparedness and perception of infection control measures against the COVID-19 pandemic by dentists in Saudi Arabia.

Materials and methods

This online survey addressed the impact and perception of the COVID-19 pandemic on dental practice in Saudi Arabia. The questionnaire comprised 26 closed-ended questions. Descriptive statistics included frequency distributions with percentages. In addition, the significance between the different demographic variables and questions about dentists’ perception of the COVID-19 pandemic was tested using the Chi-square test.

Results

COVID-19 management in dental clinics varied in terms of adherence to the Ministry of Health (MOH) guidelines. Dental clinics’ screening questionnaire for patients showed good adherence (67%), while the lowest agreement was detected with the question on the existence of an airborne infection in the isolation room (15%). Almost two-thirds of the respondents agreed that the dental reception area adopted the proper COVID-19 preventive measures. Greatest accord was observed in their answers on questions about dentists’ perception of the COVID-19 pandemic, ranging from 64%–89%. In addition, there were statistically significant differences in questions about the perception of dentists towards the COVID-19 pandemic by different demographic variables such as age and years of work experience (p < 0.05).

Conclusion

The response of most dentists regarding the preparedness and perception of infection control measures against the COVID-19 pandemic was positive. Dental clinics need to adhere more to the MOH recommendations in preparedness of their facilities or by educating their dentists and staff.

Oral and maxillofacial surgical services amid COVID-19 pandemic: perspective from Tanzania

The coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 is a global pandemic that affects individuals from all walks of life. Considering that the virus can be passed on directly from person to person through respiratory droplets, contact, fomites, and saliva, the oral and maxillofacial surgeons are exposed to COVID-19 in their daily clinical duties. This is because of the nature of their work, which entails working within a short distance from patients' oral cavity and upper airway. As such, there is a need for having locally tailored standard guidelines for managing patients with oral and maxillofacial conditions during the COVID 19 pandemic in Tanzania.

A Dental Response to the COVID-19 Pandemic-Safer Aerosol-Free Emergent (SAFER) Dentistry

Dental services are significantly impacted by the COVID-19 pandemic. Almost all dental procedures carry a high infection risk for providers and patients due to the spread of aerosols. As a consequence, public health agencies and professional associations have issued guidelines for enhanced infection control and personal protection equipment and have also limited care to urgent or emergency services. However, there is no dental service concept for pandemic disaster preparedness or response that might be applied. Moreover, pathways to dental care provision in a post-pandemic future with persisting risks are needed. We propose Safer Aerosol-Free Emergent Dentistry (SAFER Dentistry) as one approach to dental services during and emerging from the pandemic. The concept's starting point is the identification of the most common patient needs. The next step is to replace common treatments addressing the most frequent needs with alternative interventions involving a lower infection risk because they do not generate aerosols. SAFER Dentistry is innovative, avoids risk, and responds to the requirements of a pandemic and post-pandemic emergency where the risk of airborne disease transmission remains high. SAFER Dentistry thereby ensures continuity of dental services while protecting providers and patients from infectious pathogens. Moreover, SAFER Dentistry allows dental service providers to remain operational and generate income even under pandemic conditions. Potential implementation and policy options for SAFER Dentistry include universal availability without co-payments by patients and a uniform bundled payment scheme for providers to simplify budgeting, reimbursement, and administration during a pandemic. Adaptations and adjustments of the concept are possible and encouraged as long as the principle of avoiding aerosol-generating procedures is maintained.

Management of oral medicine emergencies during COVID-19: A study to develop practise guidelines

Coronavirus disease (COVID-19) pandemic has become a significant global public health concern. Since the announcement of the Public Health Emergency of International Concern, many countries have implemented lockdown and restrictive quarantines; therefore, routine dentistry, as well as oral medicine practise, have been suspended in several countries. However, urgent oral cares and emergencies are still operated and delivered by on-call dental practitioners. The objective of this study was to investigate the management of oral medicine emergency during a viral pandemic such as COVID-19. During the lockdown period, digital technologies, such as video conferencing with Zoom, Google Meeting or WhatsApp, are useful and efficient tools that oral medicine practitioners could consider to use for patient triage, managing emergencies, reassure, and follow patients remotely. Oral medicine emergencies can be carefully evaluated and triaged via video conferencing and sometimes phone contact, to avoid life-threatening risks while realising the limitations by both patient and clinician.

Reopening of dental clinics during SARS-CoV-2 pandemic: an evidence-based review of literature for clinical interventions

Background

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes serious acute respiratory diseases including pneumonia and bronchitis with approximately 2.3% fatality occurrence.

Main body

This study argues the main concepts that need to be considered for the gradual reopening of dental offices include treatment planning approaches, fundamental elements needed to prevent transmission of SARS-CoV-2 virus in dental healthcare settings, personal protection equipment (PPE) for dental health care providers, environmental measures, adjunctive measures, and rapid point of care tests in dental offices.

Conclusion

This article seeks to provide an overview of existing scientific evidence to suggest a guideline for reopening dental offices.

Mapping COVID-19 related research from Saudi Arabia, a scoping review. Between reality and dreams

OBJECTIVES

To map research production by Saudi-affiliated investigators in order to identify areas of strength and weakness. Method: We followed the Arksey and O'Malley (2005) framework. Medline and Cochrane databases were searched with a focus on identifying articles related to COVID-19 and Saudi Arabia following the PRISMA protocol. The study was conducted at King Saud University, Riyadh, Saudi Arabia between March and May 2020. Results: A total of 53 articles were ultimately included. Most of the research production from Saudi Arabia was opinion and narrative reviews related to the clinicopathological features of COVID-19 as well as control and prevention of virus spread.  Conclusion: The results of this scoping review identify a relative deficiency in original research, which requires further investigation.
