Coronavirus Disease 2019 (COVID-19): Emerging and Future Challenges for Dental and Oral Medicine

Elevated α-hydroxybutyrate dehydrogenase as an independent prognostic factor for mortality in hospitalized patients with COVID-19

AIMS

Many studies have explored the clinical characteristics of patients with coronavirus disease (COVID-19), especially patients with cardiovascular disease. However, associated mechanisms and markers remain to be further investigated. This study aimed to investigate the effect of α-hydroxybutyrate dehydrogenase (α-HBDH) levels on disease progression and prognosis of patients with COVID-19.

METHODS AND RESULTS

One thousand seven hundred and fifty-one patients from the Leishenshan hospital in Wuhan were divided into elevated and normal groups by α-HBDH level, and the clinical information between the two groups was compared retrospectively. The main outcome evaluation criteria included in-hospital death and disease severity. Univariate and multivariate regression analyses, survival curves, logistic regression, and receiver operating characteristic curve models were performed to explore the relationship between elevated α-HBDH and the two outcomes. Besides, curve fitting analyses were conducted to analyse the relationship between computed tomography score and survival. Among 1751 patients with confirmed COVID-19, 15 patients (0.87%) died. The mean (SD) age of patients was 58 years in normal α-HBDH group and 66 years in elevated α-HBDH group (P < 0.001). The mortality during hospitalization was 0.26% (4 of 1559) for patients with normal α-HBDH levels and 5.73% (11 of 192) for those with elevated α-HBDH levels (P < 0.001). Multivariate Cox analysis confirmed an association between elevated α-HBDH levels and higher risk of in-hospital mortality [hazard ratio: 4.411, 95% confidence interval (95% CI), 1.127-17.260; P = 0.033]. Multivariate logistic regression for disease severity and α-HBDH levels showed significant difference between both groups (odds ratio = 3.759; 95% CI, 1.895-7.455; P < 0.001). Kaplan-Meier curves also illustrated the survival difference between normal and elevated α-HBDH patients (P < 0.001).

CONCLUSIONS

Our study found that serum α-HBDH is an independent risk factor for in-hospital mortality and disease severity among COVID-19 patients. α-HBDH assessment may aid clinicians in identifying high-risk individuals among COVID-19 patients.

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.

Aerosols modification with H2O2 reduces airborne contamination by dental handpieces

Objective: We designed an in vitro study to evaluate the efficiency of an 0.5 vol% hydrogen peroxide-based spray in reducing Coronavirus 229E spread during a conventional dental procedure.

Methods: A class III cabinet-like chamber was custom-built, using phantoms for both patient and operator. A suspension of HCoV-229E in artificial saliva having a similar viral load to SARS-CoV-2 asymptomatic patients was inoculated inside the patient’s phantom mouth. A 10 s-lasting dental procedure was performed using an aerosol-generating air-turbine, with or without high-volume evacuation (HVE). The effect of 0.5 vol% H₂O₂ cooling spray in reducing viral loads was tested. Viral presence on the operator phantom was assessed by Real-Time quantitative PCR on the mask’s outer surface, on the phantom’s forehead, and inside its mouth.

Results: When the H₂O₂ cooling spray was used, as compared to the conventional spray, viral loads were significantly lower on all tested sites, falling below the detection limit. Viral loads did not significantly change in any tested site when HVE was used.

Conclusion: The use of 0.5 vol% H₂O₂ cooling spray by dental handpieces drastically reduced the possibility of coronaviruses spread during aerosol-generating dental procedures. This strategy deserves further consideration among the preventive measures to be adopted during the SARS-CoV-2 pandemic.

Spanish Dentists' Awareness, Knowledge, and Practice Regarding COVID-19: A Multiple Regression Analysis

Introduction

During the first months of the coronavirus disease 2019 (COVID-19) pandemic, Spain had the highest mortality rate and the second-highest infection rate in the world.

Objective

To analyze the occupational situation of dentists, hygienists, and dental auxiliary staff during the peak of the pandemic, after the state of alarm was declared in Spain, and when the state of alarm was declared. In addition, a possible relationship between the geographical distribution of infected people and the availability of individual protection systems was investigated.

Material and Methods

A cross-sectional questionnaire was answered by 6470 dentists and dental staff via WhatsApp and social media.

Results

A total of 1 in 4 dental professionals ceased working completely. Of those that kept working, 25.28% of dentists and 19.61% of hygienist-auxiliary were equipped with filtering face piece (FFP) 2 masks (P < .05), and 61.8% complied with the official protection recommendations set by the General Council of Dentists of Spain. Nearly 59.4% of respondents had symptoms, but only 1.5% of dentists were tested, with 14% of dentists in isolation at the time of response. Overall, it is suggested that 10% of dental professionals may have been in direct contact with the coronavirus.

Conclusions

Direct contact of Spanish dental health professionals with severe acute respiratory syndrome coronavirus disease 2 (SARS CoV-2) has been high during the most active phase of the pandemic. Dental professionals did not have personal protective equipment (PPE) necessary to care for patients, a situation that justified the reduction in scheduled dental care and only emergencies being treated. The Spanish geographical regions with the highest number of contagions had the least amount of individual protective resources (FFP2 and FFP3 masks).

COVID-19 Pandemic and Its Impact on Pediatric Dentistry in Austria: Knowledge, Perception and Attitude Among Pediatric Dentists in a Cross-Sectional Survey

Introduction

The Novel Coronavirus Disease (COVID-19) outbreak is affecting people worldwide. Given the frequent production of aerosols, dentists are a high-risk group for infection. The aim of this study was to assess the knowledge, perception and attitude regarding COVID-19 among pediatric dentists in Austria.

Methods

An online survey was distributed among the 128 pediatric dentists that are members of the Austrian Society of Pediatric Dentistry. The questionnaire was divided into three sections: 1) dentists’ demographic characteristics, 2) general knowledge and attitude, 3) COVID-19 with a focus on pediatric dentistry.

Results

Seventy-five dentists replied; 58 questionnaires could be included in the analysis (93.1% female). Pediatric dentists were found to have good general knowledge of COVID-19. However, only 10% had attended training or lectures and 36.2% rated their role in teaching patients about COVID-19 as being very significant. At the beginning of the outbreak, 78.6% only offered emergency services. Currently, only 10.3% of the dentists work without FFP2/3 mask when producing aerosols.

Discussion

Austrian pediatric dentists were aware of the general aspects of COVID-19. Those, who had their practice open mostly followed national and international recommendations given and only offered emergency visits.

Psychological Distress and Post-Traumatic Symptomatology Among Dental Healthcare Workers in Russia: Results of a Pilot Study

The spread of SARS-CoV-2 infection has increased the risk of mental health problems, including post-traumatic stress disorders (PTSD), and healthcare workers (HCWs) are at greater risk than other occupational groups. This observational cross-sectional study aimed to explore the symptoms of depression, anxiety, and PTSD among dental HCWs in Russia during the coronavirus disease 2019 (COVID-19) pandemic. The survey was carried out among 128 dental HCWs from three dental clinics of Ekaterinburg, Russia. The mean age of the sample was 38.6 years. Depression, anxiety, and stress were assessed using the Depression Anxiety and Stress Scale-21 (DASS-21); PTSD was assessed using the PTSD Symptom Scale-Self-Report (PSS-SR); subjective distress was assessed using the Impact of Event Scale-Revised (IES-R). The results indicated that 20.3-24.2% HCWs had mild to extremely severe symptoms of psychological distress, and 7.1-29.7% had clinical symptoms of PTSD. No differences between females and males were revealed. HCWs working directly with patients had significantly higher levels of PTSD symptoms and the risk of PTSD development compared to those working indirectly, whereas older HCWs had significantly higher levels of both psychological distress and PTSD symptoms compared to younger HCWs. Thus, dental HCWs are at high risk for psychological distress and PTSD symptoms during the COVID-19 pandemic.

Assessment of the Awareness, Perception, Attitudes, and Preparedness of Health-care Professionals Potentially Exposed to COVID-19 in the United Arab Emirates

BACKGROUND

Since COVID-19 surfaced in December 2019, health-care organizations across the globe have struggled to maintain the safety and well-being of health-care professionals (HCPs).

PURPOSE

This study investigates the HCPs' general understanding of the health risks of COVID-19 and to what extent they are equipped with the knowledge to protect themselves and others against this contagion.

METHODS

This cross-sectional study used a web-based structured questionnaire posted on the UAE government electronic survey portal. A collection of 941 HCPs from diverse general and specialty hospitals in the UAE responded to an electronic participation invite.

RESULTS

Our analysis showed that the majority of HCPs (97.6%) had updated information about COVID-19 modes of transmission, risks of contamination, high-risk groups, and the potential consequences of testing positive. Furthermore, the results of the chi-squared testing revealed that the HCPs' confidence and vigilance of the COVID-19 threats were significantly increased (p< 0.01) by being experienced, having had infection control training, or/and having undergone COVID-19 education.

CONCLUSION

We conclude that HCPs have an evidence-based understanding of the ways their own health is at risk while they are performing their duties in hospital setups. Further, the study found that HCPs who undergo special infection control training and who are kept posted on the official updates on COVID-19 are more likely to remain vigilant at all times to minimize the risks to themselves and their patients. Although the generalizability of the study findings should be considered with caution, the results could be generalizable to health-care professionals who received similar COVID-19 related training in the UAE or other regional countries.

Investigating the factors enabling the accurate implementation of the patient-assisted teledermatology model during the pandemic in Turkey: A pilot study

We aim to investigate the factors enabling the accurate implementation of the patient-assisted teledermatology model during the pandemic in our country. This single-center, a prospective-survey study was enrolled consecutively 468 patients aged 13 years and older. The patients were asked about their attitudes towards teledermatology. After the dermatological examinations, the diagnosis and management of the diseases, and classification of diseases according to lesion locations were recorded. The physician's and the patient's opinions on whether it was possible to manage properly the current medical condition through teledermatology were recorded. The patients stated that 81.2% have been keen to use teledermatology for any complaints during the pandemic. 53.7% of the patients who are positive to use teledermatology expressed that they would never use this method unless it is fully reimbursed. Although it was thought that 49.8% of the current complaints according to the patients and 56.6% to the dermatologists could be resolved appropriately by teledermatology, for 24.8% either the patient's or the physician's opinion was contrary. Being woman, high-income level, and the presence of facial dermatosis favorably affected the patients' and physicians' evaluations regarding the suitability of the complaint to teledermatology. Factors such as low education level, insufficient technical skills to be examined alone, and the necessity of undressing for examination caused patients to consider teledermatology unsuitable for their current complaints. Priority should be given to the development of an appropriate reimbursement system and reducing potential medicolegal risks to encourage patients to participate in high-quality teledermatology.

COVID-19 Dentistry-Related Aspects: A Literature Overview

A new coronavirus (Sars-CoV-2) was detected in China at the end of 2019 and has since caused a worldwide pandemic. This virus is responsible for an acute respiratory syndrome (COVID-19), distinguished by a potentially lethal interstitial bilateral pneumonia. Because Sars-CoV-2 is highly infective through airborne contamination, the high infection risk in the dental environment is a serious problem for both professional practitioners and patients. This literature overview provides a description of the clinical aspects of COVID-19 and its transmission, while supplying valuable information regarding protection and prevention measures.

Integrating Metamaterial Antenna Node and LiFi for Privacy Preserving Intelligent COVID-19 Hospital Patient Management

Light fidelity (LiFi) and wireless fidelity (WiFi) can be applied with the same network under the different constraints, which is suitable for COVID-19 surveillance in hospitals. The LiFi network is a high-capacity and security platform. A COVID-19 surveillance system using LiFi is proposed, which consists of two switching modes: communication and surveillance. Firstly, the communication targets are to accommodate the electromagnetic interference (EMI) immunity and high-capacity and security data transmission, where secondly the COVID-19 surveillance can be applied. In operation, the up and downlink system uses a metamaterial antenna embedded by Mach Zehnder interferometer (MZI). An antenna consists of silver bars embedded at the microring center with two-phase modulators at its sides. The entangled source namely a dark soliton is applied to form the transmission, where the information security based on quantum cryptography can be managed. By using the suitable parameters, the whispering gallery modes (WGMs) are generated and the up and downlink nodes are formed. The input information is multiplexed with time to form the multiplexed signals, where the big data transmission (40 Pbit s - 1 ) can be employed. By using the surveillance mode, the plasmonic antenna can be applied for temperature and electric force sensors, which can offer the disinfectant spray and temperature sensor for COVID-19 applications. The optimum plasma force sensitivity is 0.16 N kg-1 mW-1. The center frequencies of 191.48 THz and 199.41 THz are obtained for uplink and downlink antennas, respectively. The optimum temperature sensitivity is 0.05 rads-1 °C-1. In conclusion, the novelty of proposed work is that the integrated sensor circuits are employed for COVID-19 surveillance in the hospital. The fuzzy-based system is designed for critical patient monitoring alert using this surveillance and management inside the hospital for COVID-19 patients.

Dilemma in the foreign lands during COVID-19: An outlook of expat health care professionals with a take on a social perspective

BACKGROUND

The World Health Organization (WHO) has declared novel coronavirus (COVID-19) infection a global pandemic due to the fast transmission of this disease worldwide. To prevent and slow the transmission of this contagious illness, the public health officials of many affected countries scrambled to introduce measures aimed at controlling its spread. As a result, unprecedented interventions/measures, including strict contact tracing, quarantine of entire towns/cities, closing of borders and travel restrictions, have been implemented by most of the affected countries including the Kingdom of Saudi Arabia.

OBJECTIVES

The aim of this paper is to share health care professionals' perspectives who are experiencing COVID19 firsthand in a foreign land. In addition, the role of the Saudi governance to combat the current situation is also discussed.

DISCUSSION

Personal and previous experiences as related to Middle East respiratory syndrome coronavirus (MERS-CoV) by the authors has been compared to the current situation and how it affected our thoughts and management. A review of the evidence-based literature was conducted to investigate the demographics of the region; and to understand the awareness of the various tools that are available and how they were utilized in the present situation of pandemic.

CONCLUSIONS

Saudi Arabia has been challenged during the pandemic as are other countries.

Awareness and Knowledge of SARS-CoV-2 Infection among Dental Professionals According to the Turkish National Dental Guidelines

The objective of the current survey was to assess the awareness of the dental professionals according to the principals described by the Turkish Dental Association (TDA). A questionnaire including the socio-demographic data, specialties/academic degree, institutions/affiliations, the knowledge about COVID-19, the number of patients examined and dental treatments performed during the COVID-19 pandemic, the knowledge of protection based on the guidelines described by TDA, contamination with COVID-19 and the psychological complaints has been used. A total of 947 (63.1%) dentists enrolled the study. The results showed satisfactory knowledge about the COVID-19 etiology, mode of transmission and the pre-procedural cautions as the majority of them had a fair level of knowledge with significantly higher knowledge among specialized respondents. The participants have also recorded a good judgment towards performing the emergency dental treatment during the current COVID-19 pandemic which corresponds with the guidelines determined by TDA. Considering the updates on the transmission of COVID-19 and protective strategies, there is an urgent need for improvement of dentists’ knowledge about risk assessment via training programs. The incidence of positive testing among dental professionals also necessitates immediately testing of asymptomatic Turkish dental professionals.

The impact of the COVID-19 epidemic on the utilization of dental services and attitudes of dental residents at the emergency department of a medical center in Taiwan

Background/purpose

Dental visits are a high risk activity during the COVID-19 pandemic. This study investigated the utilization of emergency dental services and clinical practical attitudes of dental residents in this period.

Materials and methods

Retrospective chart data from 13th November 2019 to 31st March 2020 in Kaohsiung Medical University Hospital, Taiwan were used. We obtained electronic medical records to review data from 515 patients who visited the emergency department with dental complaints and we contacted the 26 residents assigned to act as primary care providers to participate in this study.

Results

After the COVID-19 outbreak, 17% fewer patients had dental emergency utilization at a hospital emergency center relative to the previous period. A survey of residents also showed a decline in the number of patients. There were no significant differences of patients' problems and diagnoses between the two periods. After the COVID-19 outbreak, 61.5% of the residents were afraid of being infected by a patient's disease and the proportions of dentists wearing waterproof gowns, face shields, and surgical hair caps were 76.9%, 88.5%, and 76.3%, respectively. These variables increased significantly after the outbreak of COVID-19.

Conclusion

Despite the trend of a decreased number of patients, their utilization of dental emergency services seems to be similar before and after the COVID-19 outbreak, possibly related to strict hospital infection control policies and the relatively low number of COVID-19 confirmed patients internationally at that time.

Mean age of the patients treated in the isolated ward: children 8.6±3.6, adults 39.1±13.8 years. People of active working age comprised 72% of all adult patients. Males filed for dental assistance more than females (54%). ICD K04.5 was established diagnosis in 52% of cases.

CONCLUSIONS

We managed to demonstrate high efficiency in utilizing telehealth technology. An issue of organizing medical dental care at the II level healthcare institution for adult population and for children diagnosed with new coronavirus infection COVID-19 in the heavy populated metropolis was solved.

Challenges, limitations, and solutions for orthodontists during the coronavirus pandemic: A review

INTRODUCTION

Orthodontic patients worldwide missed appointments during the early months of the coronavirus disease 2019 (COVID-19) pandemic. A significant problem with this virus is its high transmission power. Asymptomatic patients can transmit the virus. The aim of this review is to examine orthodontic emergencies and the necessary strategies and measures for emergency and nonemergency treatment during the coronavirus pandemic.

METHODS

The following databases were comprehensively searched: PubMed, MEDLINE, Scopus, and Google Scholar. Up-to-date data released by major health organizations such as the World Health Organization and major orthodontic associations involved in the pandemic were also evaluated.

RESULTS

Few studies were conducted on managing orthodontic offices or clinics during the pandemic, and most are not of high quality. Appropriate communication is the most important issue in managing orthodontic patients, particularly virtual counseling. Many orthodontic emergencies can be managed in this way by patients themselves. Most studies recommend using the filtering facepiece 2 masks, equivalent to N95 masks for non-COVID-19 patients undergoing aerosol-generating procedures and all suspected or confirmed COVID-19 patients in orthodontic visits.

CONCLUSIONS

At this time, there are no definitive clinical protocols supported by robust evidence for orthodontic practice during the COVID-19 pandemic. Orthodontists should not rush to return to routine orthodontic work and should follow state guidelines. Nonemergency orthodontic visits should be suspended during the severe acute respiratory syndrome coronavirus 2 pandemic in high-risk areas. Resuming orthodontic procedures during the pandemic requires paying special attention to screening, performing maximum efforts to reduce aerosol generation, using appropriate personal protective equipment, having proper ventilation, and fully adhering to sterilization and disinfection principles.

Guidelines for oral and maxillofacial imaging: COVID-19 considerations

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus causing the current coronavirus disease 2019 (COVID-19) pandemic, is not only highly infectious but can induce serious outcomes in vulnerable individuals including dental patients and dental health care personnel (DHCPs). Responses to COVID-19 have been published by the Centers for Disease Control and Prevention and the American Dental Association, but a more specific response is required for the safe practice of oral and maxillofacial radiology. We aim to review the current knowledge of how the disease threatens patients and DHCPs and how to determine which patients are likely to be SARS-CoV-2 infected; consider how the use of personal protective equipment and infection control measures based on current best practices and science can reduce the risk of disease transmission during radiologic procedures; and examine how intraoral radiography, with its potentially greater risk of spreading the disease, might be replaced by extraoral radiographic techniques for certain diagnostic tasks. This is complemented by a flowchart that can be displayed in all dental offices.

Dentistry for children during and post COVID-19 pandemic outbreak

BACKGROUND

During and post COVID-19 pandemic outbreak, it is essential for safeguarding this viral infection control and prevention in pediatric dental practices. The role of parents and pediatric dentist and their dental team requires specific guidance to deal with dental problems of children in the dental operatory during and post-pandemic outbreak of COVID-19 disease.

PURPOSE

To report dentistry for children during and post COVID-19 pandemic outbreak.

CONCLUSIONS

The present review highlights the clinical features, possible modes of transmission of COVID-19 in dental operatory, preventive strategies, emergencies that pose a significant challenge, and treatment strategies for dealing with children and parents during and post COVID-19 pandemic. Absolute measures for children during their visit to dental operatory, quality control for pediatric dental clinics, and additional preventive measures associated with examinations and management of dental problems in children have been covered in this insight.

Dental practice in the era of COVID-19: A review of literature

Dental practitioners confront the highest risk of COVID-19 infection due to constant exposure to saliva, droplets, blood, and aerosols. Despite the suspension of routine dental care in many countries around the world, dental professionals perceive a moral duty to take part in the global fight against the pandemic. Therefore, dental professionals should be vigilant in defending against the transmission of the virus and as well as in the diagnosis of the disease through the oral manifestations of it. We conducted a literature review on publicly available data to outline updates on guidelines and studies of dental settings during the COVID-19 era. In this literature review, the categorization of the patients for dental treatments, protective precautions for the dental practice, considerations for dental drug prescription, and oral manifestations of the disease has been reviewed.

Knowledge and Practice of COVID-19 Infection Control Among Dental Students and Interns: A Cross-Sectional Survey

INTRODUCTION

To assess the knowledge and practice of dental students and interns regarding coronavirus disease (COVID-19) based on academic level and university.

MATERIALS AND METHODS

A cross-sectional survey was carried out among interns and dental students using self-administered, structured questionnaire regarding knowledge and clinical practice with respect to COVID-19 pandemic.

RESULTS

A total of 126 completed questionnaires were received. A majority of the study participants (98.4%) stated they were aware of the COVID-19 infection control policies. Most participants (83.3%) had attended training or lectures about COVID-19. Most of them stated that the N59 mask is the best mask against the disease (81.7%). Significant variations between academic years and genders were revealed regarding the clinical practice. Uncertainty existed regarding quarantining, preprocedural mouth wash, and handwashing versus desensitizing.

CONCLUSION

The level of knowledge of the participants was reasonable. Areas of deficiency in knowledge were observed among junior dental students. Further training in infection control measures and formulation of new guidelines are recommended to increase the knowledge and preparation of dental students regarding COVID-19 in dental settings, as well as reduce the transmission of infection.

CONCLUSION

The impact of the pandemic of COVID-19 affects dental education a lot. The model of dental education should be innovated to suit different situations and novelty intelligent technology should be applied for future dental education.

Awareness and knowledge of undergraduate dental students about the signs and symptoms of Corona viral infection (COVID-19), and the required infection control measures to prevent its spread

BACKGROUND

Coronavirus disease (COVID-19) is considered a highly contagious disease with flu-like symptoms and causing relatively high level of death. It can be transmitted from a person to another through droplets and that makes the dentists at high risk of infection. Therefore, the aim of the current study was to assess the awareness and knowledge of dental students about the signs and symptoms of Coronavirus disease (COVID-19) and to evaluate their awareness about the required infection control measures during the dental treatment to control the spread of the disease. A questionnaire was formed using Google forms and distributed among dental students and interns in different universities in Cairo, Egypt. Questions were about signs and symptoms of COVID-19, attitude of the dentists toward dental treatment of suspected patients and the required personal protective equipment (PPE) and infection control measures at the dental clinic.

RESULTS

The majority of the participants strongly agreed/agreed that COVID-19 is a highly dangerous disease, Participants reported that the most common symptom is difficulty in breathing (89.4%) followed by fever (84.4%). Face shield was the most recommended personal protective equipment (PPE) during dental treatment (98.6%) followed by disposable gown (96.3%). The majority of participants (84.8%) recommended using 70% ethyl alcohol as the first method to disinfect surfaces in between dental visits, followed by sodium hypochlorite.

CONCLUSIONS

Dental students and interns in Cairo, Egypt, have good knowledge and awareness about COVID-19 and the necessary precautions required to provide adequate dental treatment for the patients during the pandemic COVID-19; however, the importance of infection control should be highlighted for both clinical and preclinical dental students, to provide safe dental treatment to the patients as well as protection of the dentists and healthcare workers.

[Key dental challenges during COVID-19 pandemic: oral health monitoring in patients with chronic oral mucosal diseases]

OBJECTIVE

To develop an effective system of an interactive dynamic telemonitoring of oral health in patients with oral lichen planus (LP) during the COVID-19 pandemic.

MATERIAL AND METHODS

The observational longitudinal prospective cohort study (follow-up for 12 months) involved 53 patients (19 men and 34 women aged 49-65 years) with various forms of LP in persistent remission. During the entire observation period dentists carried out telemonitoring (through a Telegram group) of oral health of patients with LP registering the preservation/coming out from remission, as well as the causes of exacerbation of LP.

RESULTS

The developed interactive monitoring system based on the use of available video feedback communication technologies (via Telegram, WhatsApp, Viber messengers) provided stable remission in 28.3% of patients with LP (mainly typical and hyperkeratotic forms) and effective relief of exacerbations (mainly erosive-ulcerative forms) associated with the new coronavirus infection COVID-19 in 35.8% of cases, exacerbation of concomitant systemic pathology (excluding COVID-19) in 16.9%, local traumatic risk factors in 15.1%, development of post-vaccination reactions in 3.9%. COVID-19-associated exacerbation of LP is a polymorphic symptom complex manifested by a change in classical clinical picture and heavier course of skin-mucosal dermatosis due to the addition of new, atypical for LP, manifested COVID-19-associated intraoral symptoms and generalization of skin lesions. Periods of exacerbation of LP in COVID-19 patients are significantly longer, with shorter remissions than in the prepandemic period.

CONCLUSION

Interactive telemonitoring of oral health in patients with chronic oral mucosal diseases is a safe and effective tool for dispensary observation, management and maintenance of social communications during periods of social isolation.

Recommendations for Managing Endodontic Emergencies during Coronavirus Disease 2019 Outbreak

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.

Online consultation and emergency management in paediatric dentistry during the COVID-19 epidemic in Wuhan: A retrospective study

BACKGROUND

The COVID-19 pandemic posed a great challenge to paediatric dentistry, which confronted with the restriction of service and resource shortage.

AIM

To retrospectively analyse the information of children's dental online health consultation during the COVID-19 pandemic in China, and to provide methods to distinguish between dental emergencies and non-emergencies as well as their management.

DESIGN

We collected all the online consultation information in Dept. of Paediatric dentistry, School & Hospital of Stomatology, Wuhan University, from 2 February to 31 March 2020, and extracted the information of age, gender, reason for consultation, description of symptom, and preliminary diagnosis of the children.

RESULTS

A total of 474 online consultations of paediatric dentistry were included within 59 days during lockdown, and 190 (40.1%) were dental emergencies and 284 (59.9%) non-emergencies. Of 190 emergency consultations, 186 (97.9%) showed swelling, pain, and trauma with or without systemic symptoms. Among 284 non-emergency consultations, retained primary teeth (n = 126) and orthodontic consultation (n = 53) were the most common reasons for consultation.

CONCLUSION

The paediatric emergency and non-emergency problems should be clearly distinguished and sufficient instructions provided in the special period of COVID-19. Priorities also should be set to deal with urgent conditions after the release of lockdown.

Knowledge of COVID-19 and its implications in dental treatment, and practices of personal protective equipment among dentists: A survey-based assessment

BACKGROUND

Oral health-care providers are always at a risk of transmitting or acquiring airborne, saliva-borne, or blood-borne infections due to their proximity to the patient's mouth, contact with saliva, and handling of sharp instruments. the aim this study was to evaluate the knowledge of the dentists regarding COVID-19, methods to prevent its transmission, and implications of COVID-19 in dental treatment.

MATERIALS AND METHODS

It was a cross-sectional online survey. There were 35 questions in total, divided into sections of knowledge of COVID-19, practices of personal protective equipment (PPE), and knowledge of implications of COVID-19 in dental treatment. Both convenience sampling and snowball sampling were used, so that maximal participation could be ensured. The results were analyzed using descriptive statistics and making comparisons among various groups. The data were summarized as proportions and percentages (%). All the associations were tested using the Chi-square test, ANOVA, and Pearson's correlation coefficient. Statistical analyses were performed using SPSS version 19.0.

RESULTS

26.8% of respondents had a high knowledge, 61.5% had good knowledge, 10.1% had low knowledge, and 6 (1.5%) had nil knowledge about COVID-19. No significant association was found between qualification and knowledge level among the respondents (P = 0.053). Both graduates and postgraduates had low knowledge regarding effective PPE components (P = 0.053), donning (P = 0.888), and doffing (P = 0.745). Only 52.9% of postgraduates and 43.7% graduates answered correctly about the sequence of donning, and 47.9% of postgraduates and 46.1% of graduates had knowledge regarding correct doffing sequence of PPE. Furthermore, knowledge was low regarding the implications of COVID-19 in dental treatment.

CONCLUSION

Although the dentists were found to have high/good knowledge scores regarding COVID-19, there was a lack of knowledge regarding hand hygiene, proper use of PPE, and implications of COVID-19 in dental treatment. Thus, they need to be trained and sensitized regarding the same.

Oral health practitioners' knowledge, attitude, and awareness about coronavirus: A systematic review and meta-analysis

BACKGROUND

Oral health practitioners are at the frontline of infection, particularly with respiratory viruses such as the novel coronavirus. Knowledge, awareness, and attitude of these workers are considered important in preventing and controlling the outbreak. This study aims to review the literature to provide a better understanding of the status of dentists and other oral health practitioners' knowledge, attitude, and awareness about COVID-19.

METHODS

A systematic review was conducted through Web of Science, PubMed, Scopus, and ProQuest up to May 6, 2020. All the knowledge, attitude, and practice studies on oral health workers about respiratory contagious outbreak the same as severe acute respiratory syndrome, Middle East respiratory syndrome, and COVID-19 were included in the meta-analysis.

RESULTS

A total of eleven studies were included in the meta-analysis. 85.5% of the dentists and oral health practitioners had a high level of awareness about virus transmission modes (95% confidence interval [CI]: 78.6%-92.4%; P < 0.001). 80.7% of the oral health practitioners gave right answers to the questions related to virus transmission modes (95% CI: 69.9%-91.4%; P < 0.001), and 79.9% of the dentists had a positive attitude about virus transmission modes (95% CI: 66.4%-93.4%; P < 0.001).

CONCLUSION

This meta-analysis shows that the level of dentists and oral health practitioners' knowledge, awareness, and attitude was relatively high about the respiratory contagious diseases as well as COVID-19. The present results can shed further light for policymakers to support the best evidence medical education for all health-care workers the same as oral health practitioners. Preventing the dissemination of misinformation along with preparing comprehensive guidelines can be considered by the oral health policymakers, particularly in the more infected regions.

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.

Decontamination and reuse of surgical masks and N95 filtering facepiece respirators during the COVID-19 pandemic: A systematic review

OBJECTIVES

Surgical masks and N95 filtering facepiece respirators (FFRs) prevent the spread of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection and protect medical personnel. Increased demands for surgical masks and N95 FFRs during the coronavirus disease 2019 (COVID-19) pandemic has resulted in the shortage crisis. However, there is no standard protocol for safe reuse of the N95 FFRs. In this systematic review, we aimed to evaluate the effectiveness of existing decontamination methods of surgical masks and N95 FFRs and provide evidence-based recommendations for selecting an appropriate decontamination method.

METHODS

We performed systematic searches of Ovid MEDLINE and Ovid EMBASE electronic databases. The last search was performed April 11, 2020. Any trials studying surgical masks and/or N95 FFRs decontamination were included. Outcomes were disinfections of virus and bacteria, restoration of the filtration efficiency, and maintenance of the physical structure of the mask.

RESULTS

Overall, 15 studies and 14 decontamination methods were identified. A low level of evidence supported 4 decontamination methods: ultraviolet (UV) germicidal irradiation (9 studies), moist heat (5 studies), microwave-generated steam (4 studies), and hydrogen peroxide vapor (4 studies). Therefore, we recommended these 4 methods, and we recommended against use were given for the other 10 methods.

CONCLUSIONS

A low level of evidence supported the use of UV germicidal irradiation, moist heat, microwave-generated steam, and hydrogen peroxide vapor for decontamination and reuse of N95 FFRs. These decontamination methods were effective for viral and bacterial disinfection as well as restoration of the filtration efficiency, and the physical structure of the FFRs.

Can preprocedural mouthrinses reduce SARS-CoV-2 load in dental aerosols?

Dental professionals work closely with patients and present an increased risk of person-to-person transmission of SARS-CoV-2. Moreover, the use of ultrasonic scalers, air-water syringes, and slow and high-speed handpieces, which are common in the dental office, generate spatter and aerosol. The use of preprocedural mouthrinses has been proposed to reduce the viral load in saliva and oropharyngeal tissues, thus decreasing viral load in dental aerosol. Although some mouthrinses demonstrates an antiviral effect, there is limited evidence about the clinical efficacy of any mouthrinse in the reduction of SARS-CoV-2 in the dental aerosol. We hypothesized that mouthrinses may reduce SARS-CoV-2 viral load in the oropharynx and its fluids reducing viral load in dental aerosol. The potential use of mouthrinses is discussed, along with proposal of in vitro and clinical studies, in order to evaluate this hypothesis. If this hypothesis holds true, dental professionals and patients may benefit from the routine use of preprocedural mouthrinses.

Mothers' Knowledge, Attitudes, and Fears About Dental Visits During the COVID-19 Pandemic: A Cross-sectional Study

OBJECTIVES

This study aimed to assess mothers' knowledge of coronavirus disease 2019 and to evaluate their attitudes and fears about dental visits during the pandemic.

MATERIALS AND METHODS

A structured questionnaire, developed in English and Arabic, adapted from previous questionnaires was remotely applied to a sample of 833 mothers of children aged 17 years and younger, from different socioeconomic backgrounds. Eligible participants were encouraged to invite others. The questionnaire collected information on knowledge about COVID-19, dental visit patterns, willingness of mothers to take their children to the dentist, and factors affecting it during the pandemic. Frequencies and percentages of categorical variables were presented, and predictors of willingness to visit a dentist during the pandemic were examined by logistic regression.

RESULTS

Mothers who perceived the dental clinic to be of less or similar danger to public places were more willing to take their children to the dentist during the pandemic than were those who perceived it to be more dangerous (odds ratio [OR] = 2.9, 95% confidence interval [CI]: 1.2-7.0; OR = 2.3, 95% CI: 1.1-4.8, respectively). Mothers who were willing to go to the dentist during the pandemic were more likely to take their children to the dentist compared with mothers who were not willing to go themselves, OR = 16.9 (6.0-47.1). The most commonly reported barrier to visiting the dental clinic was fear of contracting the virus from someone there (80%). Most parents did not take their child to the dentist during the pandemic (83%), and 24% of those who had an appointment did not allow their children to attend.

CONCLUSION

Mothers were unlikely to take their children to the dentist except for an emergency and perceived the dental clinic as a risky place for contracting the virus. More reassuring information about infection control measures at dental clinics should be delivered to this population.

Paediatric Oral Health during and after the COVID-19 Pandemic

BACKGROUND

During the period of health emergency linked to the current COVID-19 pandemic, the paediatric dentists' management of oral health problems in children must have as primary objective the control of the spread of the disease according to specific protocols aimed at minimizing the risk of viral transmission.

AIM

This paper examines the possible clinical conditions that may require intervention by the paediatric dentist, distinguishing clinical situations that fall into the category of paediatric dental emergencies from conditions of oral pathologies that normally do not represent an emergency. The definition of rigorous and highly effective infection control protocols in the dental settings must therefore be complemented by the development and strengthening of remote communication techniques with the parents, who must be adequately educated on preventive and palliative measures for the management of their children's oral health, with the aim of postponing clinical attendance to when the circumstances become favourable.

CONCLUSIONS

The experience gained with these approaches and models of treatment, where remote interaction techniques play a central role, will hone the communication skills of the paediatric dentist and will retain its usefulness even at the end of the current emergency period.

Operating Room Protocols and Infection Control

In the modern day’s Oral and Maxillofacial surgical practice, complex surgical and aesthetical procedures are being carried out associated with an increased risk of infectious complications. Therefore, to ensure better outcomes of the surgical procedures, it is absolutely necessary that appropriate measures must be taken to decrease the incidence of associated infections. The practices to be carried out for infection control include proper scrubbing procedures for both patient and the operator, specific protocols to be followed by the operating personnel at the time of procedures, proper handling of the instruments and maintaining an aseptic environment throughout the procedure. The main aim of this chapter is to provide information on the preoperative, operative and post-operative protocols that should be adhered to improve the safety of the patients undergoing surgical procedures.
