Guidelines for dental care provision during the COVID-19 pandemic

"Lessons to Be Learned After the Storm"-A Retrospective Study on the Characteristics and Management of Dental Emergency Patients During the COVID-19 Outbreak in Riyadh

Background/Objectives: There is a limited understanding of the variables relating to dental patients and the treatment provided during the initial phase of the COVID-19 lockdown in our region. This study aimed to qualitatively analyze these patient variables and determine the associations between treatment recommendations and the specialty of the doctor at the point of care. Methods: The present study was retrospective, cross-sectional, and analytical in nature. Data regarding symptoms, diagnosis, treatment, and the attending specialist were retrieved from the patient management software for patients seeking emergency dental services during the COVID-19 lockdown (23 March 2020 to 23 April 2020) in primary and tertiary public hospitals of the National Guard Health Affairs in Riyadh, Saudi Arabia. The association between exploratory (symptoms, diagnostic tool, specialist at point of care) and dependent variables (given diagnosis and treatment) was assessed using Fisher's exact test and multinomial regression analysis. Results: A total of 151 dental patients attended the outpatient/emergency clinics during this period. The mean age of the patients in this study was 31.4 (±19.0) years. Compared to physicians, general dentists [OR 0.56, CI 0.29-10.47] were more likely to give an inappropriate diagnosis and treatment, whereas residents [OR 2.70, CI 1.65-98.17] and resident endodontists [OR 2.30, CI 1.28-78.11] were more likely to give an appropriate diagnosis and treatment. Conclusions: The findings of this study highlight the need for a greater number of endodontists at the forefront of screening and providing dental care during such health catastrophes.

Aerosol Dispersion and Efficacy of Protective Strategies During Dental Procedures

INTRODUCTION AND AIMS

Aerosol generation during dental procedures poses significant risks due to the potential for transmitting aerosol-bound microorganisms, including those in dental unit waterlines. This study aimed to quantify aerosol dispersion at various distances from dental procedures using a high-speed electric handpiece, with a focus on the effectiveness of various aerosol mitigation strategies.

METHODS

Employing a mannequin head with an artificial tooth (typodont), we simulated clinical settings without the use of saliva to solely assess the contribution of dental unit waterlines and mechanical factors to aerosol production. Measurements were taken using a spectrometer at distances of 0, 0.9, and 1.8 meters from the handpiece.

RESULTS

The results showed no significant difference in aerosol dispersion between 0.9 and 1.8 meters without evacuation. In contrast, the use of high-volume evacuators, particularly the Isolite system, significantly decreased aerosol dispersion across all distances.

CONCLUSION

We found that any type of high-volume evacuator can decrease aerosol dispersion, but the use of Isolate was the most effective.

CLINICAL RELEVANCE

The results from this study can influence choice of safety measures to minimize aerosol spread during dental procedures.

Restorative and endodontic clinical strategies during COVID-19 (SARS-CoV-2) pandemic: a revision of the literature

The aim of this study was to analyze clinical strategies supported by validated references during two of the most frequent dental emergencies (i.e. restorative and endodontic treatment) in the COVID-19 pandemic. Coronavirus disease 2019 (COVID-19) was caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of an emergency in the health system worldwide and a potentially fatal disease. Person-to-person transmission of SARS-CoV-2 through aerosol and droplets led to extensive preventive measures to contain COVID-19 outbreak. Dental care providers have been exposed to a high risk of SARS-CoV-2 infection, due to the face-to-face communication and the exposure to saliva, blood, and other body fluids during routine interventions; this can also contribute to a high risk for cross-infection, even though dentist usually cope with those situations in everyday practice. Restorative and endodontic emergencies represented a high proportion of dental emergencies, with prolonged exposure time for dentists/endodontists in contact with suspected or confirmed infected patients. Lack of knowledge and undefined progression controlled the decision-making in clinical dentistry. The dynamicity of the situation determined change of views and recommendations in dental setting. The implementation of strict restorative and endodontics protocols are aimed at preventing circumstances similar to those observed with COVID-19.

Evaluation of the quality of safe dental services based on the perception of patients with the IPA approach: a powerful diagnostic tool for managers

BACKGROUND

In today's competitive world, especially in critical situations, dental clinic managers seek to retain customers and allocate more market share. The importance-performance analysis (IPA) technique is a powerful diagnostic tool that helps managers identify fundamental deficiencies, establish priorities and provide insights into which service improvement areas managers should focus on. This study aimed to improve the quality of life of patients at the Alborz Dental Clinic based on their perception of safe services during the coronavirus pandemic using IPA.

MATERIALS AND METHODS

In this analytical cross-sectional study, 324 patients referred to at Alborz Dental Clinic from April 2021 to February 2022 were enrolled in the study through simple random sampling. The data collection tool used was a researcher-designed questionnaire based on the indicators of the quality improvement model and the guidelines of the Ministry of Health, Medical Education and Health of Iran regarding the provision of dental services in the context of COVID-19, the validity and reliability of which were measured. The gap analysis results and determination of areas of improvement were obtained using IPA. The data analysis was performed using SPSS26 and Excel software.

RESULTS

The results of the paired ttest showed that the difference between importance and performance for all the research variables was significant (significance level less than 5%).The importance of the components exceeded their performance. The deepest gap among the five components of the model was related to accountability. IPA revealed that two variables, reliability and responsiveness, are placed in quadrant A, and three variables, tangibility, assurance, and empathy, are placed in quadrant B.

CONCLUSION

To improve the quality of safe services, dental clinic managers need to pay attention to the three dimensions of "tangibility", "assurance" and "empathy" and plan and make decisions about the two dimensions of "reliability" and "responsiveness".

Challenges and resilience of Taiwan's oral health care system after Covid-19 pandemic

This paper examines the resilience of Taiwan's oral healthcare system in response to COVID-19, focusing on pre-pandemic conditions, pandemic impacts, and policy recommendations for future resilience. In Taiwan, oral diseases were prevalent, with 80.48% of adults affected by periodontitis in 2016, and 65.43% of 5-year-old children experiencing dental caries. Taiwan's National Health Insurance (NHI) covers over 99% of the population, providing comprehensive dental care. The global budget (GB) payment system, implemented in 1998, ensured financial stability. During the pandemic, dental visits in Taiwan decreased by 5.1% in 2021 compared to 2019. Despite reduced visits, the GB system maintained financial stability, mitigating financial impacts on healthcare institutions. The pandemic generally negatively affected healthcare workers' well-being, increasing resignation intentions. However, the number of practicing dentists in Taiwan remained stable from 2016 to 2022, with slight increases. Urban-rural disparities persisted, and workplace transitions increased, indicating greater mobility among dental professionals. To enhance resilience, the following recommendations are proposed: 1. Strengthen hierarchy of oral healthcare system: Balance dental resources across regions, and improve referrals between hospital and clinics; 2. Provide integrated patient-centered care: Integrate oral health into disease prevention and offer comprehensive services across all stages of life; 3. Integrate digital technology: Promote teledentistry and leverage Taiwan's strengths in information and communication technology (ICT).

Antiseptics: An expeditious third force in the prevention and management of coronavirus diseases

Notably, severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS) and coronavirus disease 2019 (COVID-19) have all had significant negative impact on global health and economy. COVID-19 alone, has resulted to millions of deaths with new cases and mortality still being reported in its various waves. The development and use of vaccines have not stopped the transmission of SARS coronavirus 2 (SARS-CoV-2), the etiological agent of COVID-19, even among vaccinated individuals. The use of vaccines and curative drugs should be supplemented with adoption of simple hygiene preventive measures in the fight against the spread of the virus, especially for healthcare workers. Several virucidal topical antiseptics, such as povidone-iodine (PVP-I), citrox, cyclodextrins among others, have been demonstrated to be efficacious in the inactivation of SARS-CoV-2 and other coronaviruses in both in vitro and in vivo studies. The strategic application of these virucidal formulations could provide the additional impetus needed to effectively control the spread of the virus. We have here presented a simple dimension towards curtailing the dissemination of COVID-19, and other coronaviruses, through the application of effective oral, nasal and eye antiseptics among patients and medical personnel. We have further discussed the mechanism of action of some of these commonly available virucidal solutions while also highlighting some essential controversies in their use.

Factors associated with dental clinic use by clients in Nigeria during the COVID-19 pandemic

BACKGROUND

Nigeria, like many other countries, faced challenges in dental care provision during the COVID-19 pandemic, necessitating limited care to emergencies only. However, the impact of restricted access to dental services on oral health remains a concern, particularly with preventive maintenance care. This study aims to identify the factors associated with dental service utilization during the COVID-19 pandemic among patients attending dental clinics in Nigeria, and their sources of information about COVID-19.

METHODS

This cross-sectional study recruited 500 participants who had visited dental clinics before and during the pandemic. Data were collected through telephone interviews and online questionnaires between September and December 2021. Inferential analyses were conducted using ordered logistic regression models to assess the association between the independent (awareness of emergency dental treatments, knowledge of COVID-19 transmission routes in dentistry, awareness of required preparations in dental practice settings, fear of COVID-19 infection in dental settings), and dependent (utilization of dental services during the pandemic) variables after adjusting for confounding variables (age, sex, educational status, COVID-19 vaccinations status and COVID-19 status of live-in residents). The sources of COVID-19 information by dental patients was also identified. Statistical significance was established at 95% confidence level with a p value < 0.05.

RESULTS

Many participants were males (51.2%) and had tertiary education (61.6%). Fear of COVID-19 infection in dental settings was significantly associated with lower odds of utilizing dental care services during the pandemic (Adjusted Odds Ratio: -0.06, 95% Confidence Interval: -0.08, -0.01). The main sources of COVID-19 information were mass media and social networks, with only 42% receiving information from dental professionals.

CONCLUSION

Fear of COVID-19 infection in dental settings significantly influenced dental service utilization during the pandemic. Strategies to address fear and improve communication channels between dental professionals and patients are essential for promoting oral health during similar crises.

Can toothbrushing reduce the intraoral viral load of SARS-CoV-2? A pilot study with a dentifrice containing an antimicrobial phthalocyanine derivative

The aim of this study was to assess whether toothbrushing with a dentifrice containing an antimicrobial phthalocyanine derivative (APD) can reduce the intraoral viral load of SARS-CoV-2. Twenty COVID-19-positive dentate patients aged ≥18 years were selected instructed to brush their teeth for 2 min with a dentifrice containing APD. Self-collected samples of unstimulated saliva were carried out three times: T0 (baseline), T5 (5 min after toothbrushing), and T30 (30 min after toothbrushing). The analysis of viral RNA was performed by RT-qPCR for detection of three viral genes (ORF1ab, N and S genes). Results were statistically tested using Friedman's test and pairwise comparison with Bonferroni corrections, with a significance level of 5%. There was an increase in the cycle threshold (Ct) value from T0 to T5 in 13 patients (72.2%), and from T0 to T30 in 14 patients (77.8%). In two patients (11.1%) no SARS-CoV-2 was detected at T5 and five patients (27.8%) at T30. The Ct values were statistically significantly higher (p=0.020) at T30 in comparison to T0 and T5. This pilot study suggests that toothbrushing with a dentifrice containing APD could reduce the SARS-CoV-2 viral load in the oral cavity. However, further studies are needed to confirm this possible beneficial effect against SARS-CoV-2.

[Acute apical abscess and associated factors in patients during the covid-19 pandemic in a health center in Acapulco, Mexico.]

Objective

To estimate the prevalence of acute apical abscess and identify associated factors in patients of a health center from Acapulco, Mexico.

Material and methods

Epidemiological study that collected clinical records of patients during the period of october 2021. Sociodemographic and housing information was collected, as well as personal pathological and non-pathological history and a record of the diagnosis of the periapical lesion based on its clinical characteristics issued by the operator on duty. Through multivariate analysis, a factor associated with acute apical abscess was identified with the odds ratio and its 95% confidence interval as estimators of the strength of association with CIETmap statistical software.

Results

The 37% (32/87) of patients were diagnosed with the infection. In terms of gender, females were the most affected with a proportion of 56% (18/32). The most common cause was caries with 72% (23/32). The right upper second premolar was the most affected tooth with 25% (8/32). One associated factor was identified, age 36 to 62 years (ORa=3.54; CI95%a=1.27 -16.62).

Conclusion

The morbidity rate of the infection was moderate, and it is a common pathology in stomatological emergency consultations, so it is important for the professional in charge of the area to manage it clinically. It will be important to implement oral health education strategies aimed at different age groups to raise awareness of the cariogenic process and its consequences.

Impact of COVID-19 pandemic on pediatric dental procedures in primary healthcare settings in Piracicaba, Brazil: an ecological study

BACKGROUND

The COVID-19 pandemic brought significant changes to dental care, which may have affected pediatric dental care offered in primary healthcare settings. Therefore, the aim of this study was to analyze the quantity of dental procedures performed in primary healthcare for children aged 6 to 12 years, before and during the COVID-19 pandemic.

METHODS

This is an ecological study using data from the health information system of Piracicaba, São Paulo, Brazil. The variables considered were: coverage of first programmed dental consultation, restoration of permanent and deciduous teeth, topical fluoride application (individual per session), emergency care, and deciduous tooth extraction. Two periods were considered: period I (March 1, 2019 to February 29, 2020) and period II (April 1, 2020 to March 31, 2021), before and during the pandemic, respectively. Comparisons between periods were made using the paired nonparametric Wilcoxon test with a significance level of 5%.

RESULTS

There was an increase in emergency care from 15.4 to 32.4% (p = 0.0095) and a decrease in the number of restorations of deciduous teeth from 32.8 to 20.2% (p = 0.0217). The first programmed consultation showed a decrease of 9.60% (p = 0.0930) in period II.

CONCLUSIONS

The COVID-19 pandemic has hindered access to primary dental care for children, impacting the quantity of emergency care, reducing restorations of deciduous teeth, and first programmed dental consultations. These findings highlight the need for strategies to ensure that pediatric dental care is not neglected during pandemics.

An Ethical Analysis Regarding the COVID-19 Pandemic Impact on Oral Healthcare in Patients with Mental Disorders

During the COVID-19 pandemic, restrictive measures were imposed that significantly impacted the healthcare system in general, and the dental healthcare system in particular. The literature cites a possible association between mental and oral health, as psychiatric patients have decreased awareness of their oral health and, therefore, poor dental status. Moreover, several studies have found a positive association between SARS-CoV-2 infection and oral health conditions, as well as between SARS-CoV-2 infection and mental health status. This context generated multiple ethical dilemmas in the case of persons with mental health disorders who require dental treatment because they are more vulnerable in this respect. This article aims to analyze the ethical issues in dental care for patients with mental disorders concerning the COVID-19 restrictive measures. The ethical aspects involved here are the basic principles of bioethics and the related elements of accessibility, equity, consent, and confidentiality.

Effects of Chlorhexidine and Povidone-Iodine on the SARS-CoV-2 Load: A Systematic Review and Meta-analysis

The efficacy of mouthwash for reducing the viral load in patients with the novel coronavirus disease 2019 (COVID-19) remains unclear. This systematic review and meta-analysis comprehensively examined the effects of chlorhexidine (CHX) and povidone-iodine (PVP-I) on the viral load in patients with COVID-19. We performed methodological analysis, systematic review, and meta-analysis of included studies using the Comprehensive Meta-analysis Software. PubMed, EMBASE, Cochrane Library, and ProQuest were searched from December 1, 2019, to December 2, 2021. In total, we included 10 studies of 1,339 patients with COVID-19. Compared with the control group, both CHX and PVP-I significantly reduced the number of negative reverse-transcription polymerase chain reaction (RT-PCR) results (p<0.001) among COVID-19 patients. The CHX and PVP-I were effective on reducing the number of negative RT-PCR results in COVID-19 patients. Additional studies using adequate randomization methods and larger samples are warned.

A Bibliometric Study on the Top 101 Most-Cited Articles of Dental Journals of the Middle East/North Africa Countries From 2011 to 2021

Introduction: This retrospective descriptive study evaluated the Scopus-indexed dental journals and their most-cited documents affiliated with the Middle East and North Africa (MENA) countries from 2011 to 2021. Methods: Dental journals affiliated with MENA countries, their bibliometric indicators (SJR, CiteScore, SNIP, and H-index), and the 101 most cited articles of the considered journals were extracted and studied through descriptive statistics. In addition, the "citation per year" of each top 101 articles was calculated. Spearman's rho test was used for pairwise comparisons of the correlation coefficient values between each two of the considered bibliometric indicators. Results: The number of citations of the 101 most-cited papers ranged from 35 to 203. The mean (SD) citations of studied articles were 61.33 (37.58) and the median was 46. Furthermore, CiteScore had the highest significant correlation with SJR (r=0.828, P˂0.001). Moreover, the citation per year of the top 101 documents had no significant relationship with any of the journals' bibliometric indicators. Conclusion: Because journal performance and citation rate are multi-dimensional concepts, a single metric cannot express them thoroughly despite correlations between indices. "European Journal of Dentistry" from Turkey, "Saudi Dental Journal" from Saudi Arabia, and "Iranian Endodontic Journal" and "Journal of Lasers in Medical Sciences" both from Iran had the highest ranks in the SCImago portal and the highest scores in bibliometric indices amongst the MENA dental journals.

The impact of the COVID-19 pandemic on dental trauma attendance: a systematic review and meta-analysis

This systematic review and meta-analysis aimed to analyze the impact of the COVID-19 pandemic on dental trauma patient attendance. The study was registered in the PROSPERO system, using the CRD42021288398 protocol. Searching was performed in PubMed, Scopus, Web of Science, Embase, Lilacs, and OpenGrey databases, using the following keywords: "Tooth injuries," "Dental trauma," "Traumatic Dental injury," and "COVID-19". We included observational studies evaluating dental trauma in the context of the COVID-19 pandemic. Quality assessment was performed using the Joanna Briggs Institute Critical Appraisal Checklist for Cross-Sectional Studies. Meta-analysis was performed in RevMan 5.4 software with Odds Ratios as a pooled measure of effect, with a 95% confidence interval, and using random-effects modeling. After applying the eligibility criteria, 32 studies were included for qualitative analysis, in which 10 were used to assess the frequency of dental trauma diagnoses in dental emergencies. Despite the decrease of visits during COVID-19, the analysis revealed no difference between the pandemic and pre-pandemic periods. Regarding the type of dental trauma, two of the studies revealed no differences for the periods before and during the pandemic. This study revealed that the COVID-19 pandemic has not impacted the frequency or type of dental trauma compared to previous periods.

An Outlook on Dental Practices to Avoid the Oral Transmission of COVID-19

The oral microbiome plays an important role in the maintenance of immune homeostasis, whereas its association with SARS-CoV-2 infection remains under investigation. Since the oral path is one of the transmission routes for COVID-19, we attempt to show the relationship between the oral microbiome, COVID-19 infection, and oral hygiene. We highlight the importance of oral hygiene to control the infection, especially for ICU cases with COVID-19. Moreover, we present the current strategies adapted by in-person dental clinics to overcome the spread of COVID-19. New emerging policies and protocols suggested during the pandemic and their future implementation to minimize virus transmission are also summarized in this review.

Capacity planning for effective cohorting of hemodialysis patients during the coronavirus pandemic: A case study

Planning treatments of different types of patients have become challenging in hemodialysis clinics during the COVID-19 pandemic due to increased demands and uncertainties. In this study, we address capacity planning decisions of a hemodialysis clinic, located within a major public hospital in Istanbul, which serves both infected and uninfected patients during the COVID-19 pandemic with limited resources (i.e., dialysis machines). The clinic currently applies a 3-unit cohorting strategy to treat different types of patients (i.e., uninfected, infected, suspected) in separate units and at different times to mitigate the risk of infection spread risk. Accordingly, at the beginning of each week, the clinic needs to allocate the available dialysis machines to each unit that serves different patient cohorts. However, given the uncertainties in the number of different types of patients that will need dialysis each day, it is a challenge to determine which capacity configuration would minimize the overlapping treatment sessions of different cohorts over a week. We represent the uncertainties in the number of patients by a set of scenarios and present a stochastic programming approach to support capacity allocation decisions of the clinic. We present a case study based on the real-world patient data obtained from the hemodialysis clinic to illustrate the effectiveness of the proposed model. We also compare the performance of different cohorting strategies with three and two patient cohorts.

COVID-19 Risk Management in Dental Offices: A Review Article

BACKGROUND: As all the dental staff, including nurses and practitioners, are exposed to various routes of contamination due to the novel COVID-19 virus, which is still unknown to the scientific world, developing strategies to reduce the risk of transmission and decontaminate surfaces in a dental office would be of high importance. Although there is still insufficient data on managing this virus in dental offices, several studies have suggested protocols for improving care. AIM: This study aimed to review present investigations and reach a conclusion on what we know and need to know to combat this virus. MATERIALS AND METHODS: In this review, Scopus, PubMed, and MEDLINE databases were searched using the keywords “COVID-19,” “SARS-CoV-2,” “Medical Disinfectants,” “Personal Protective Equipment’s,” and “Surface Decontamination.” Articles were reviewed, and finally, relevant articles published during 2000–2022 were included in the final paper. RESULTS: The present research concluded that using a combination of the face shield and N95 masks protected the eyes, nose, and mouth. To have more efficient protection, water-resistant long-sleeved gowns and gloves were highly suggested. To overcome aerosols, high-performance air filters and ultraviolet were found quite effective. Allowing the patient to use antiseptic mouthwash before starting the treatment could reduce oral microorganisms and the following airborne contamination. CONCLUSION: This review has gathered all available data regarding dentistry and COVID-19 in order to conclude what has been achieved yet in the prevention of this virus through dental offices; however, more investigations are needed to have a definitive protocol against the virus.

An update on oral clinical courses among patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection: A clinical follow-up (a prospective prevalent cohort) study

INTRODUCTION

Contemporary literature has revealed that Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) causes acute sialadenitis and related symptoms, such as discomfort, pain, swelling, and secretory dysfunction in salivary glands. The secretory dysfunction is due to SARS-CoV-2 infection-induced xerostomia and other associated clinical courses such as sore tongue, mucosal ulcer, and gingivitis in the oral cavity. Furthermore, it has been reported that COVID-19 causes the development of other oral manifestations.

MATERIALS AND METHODS

A prospective clinical follow-up (a prevalent cohort) study was conducted to identify the possible oral manifestations of SARS-CoV-2 infection among patients admitted toat the Eka General Hospital COVID-19 treatment center. Furthermore, the study aimed to calculate the prevalence rate of oral clinical courses in the cohorts. The study consisted of two follow-up phases: Hospital and patient-home-based.

RESULTS

A total of 55 patients (36 males and 19 females) met the inclusion criteria and were followed for 7.5 weeks. The 3.5 weeks hospital-based prospective follow-up study documented an 18% (n = 10) prevalence rate of oral clinical courses among the cohorts. Twelve oral symptoms appeared in these ten patients. The manifested oral symptoms were oral mucosal lesions (n = 6), xerostomia (n = 5), and thickening of saliva (n = 1). The oral mucosal lesions per se consisted of aphthous lesions (n = 3), candidiasis (n = 1), geographic tongue (n = 1), and localized gingivitis (n = 1). The four weeks' home-based follow-up study disclosed four newly manifested oral symptoms: hemorrhagic crust, bulla, buccal mucositis, and petechiae. These manifestations appeared among six patients (four males and two females) who had not manifested any oral symptoms during the hospital-based follow-up. Accordingly, the overall prevalence of oral clinical courses among patients presented with SARS-CoV-2 is raised from 18% (n = 10) to 29% (n = 16). Similarly, the number of clinical courses increased from 12 to 16 after four additional weeks of follow-up.

DISCUSSION

The study's findings suggest the importance of initiating oral health care for patients with COVID-19. Therefore, multidisciplinary healthcare approaches should be delivered to assure optimal health outcomes. Accordingly, oral health professionals must be a substantial part of the interdisciplinary approach in caring for patients with COVID-19.

Mouth shield to minimize airborne transmission risk of COVID-19 and other infectious diseases in the dental office

Transmission of coronavirus disease (COVID-19) and other infectious diseases is a significant risk during dental procedures because most dental interventions involve aerosols or droplets that could contaminate the surrounding environment. Current protection guidelines to address the high risk of droplets, aerosols, and airborne particle transmission of COVID-19 in the dental office recommend minimizing aerosol-generating procedures. In this paper, an innovative mouth shield is presented that should minimize water backsplash from the air-water syringe during dental treatment. The mouth shield can be added to the personal protective equipment to provide the dental team with extra protection. It can be made of different materials, is straightforward, inexpensive, and safe to fabricate, and is easy to use.

The impact of a pandemic on dental professionals' work and personal lives: A qualitative study with implications for primary healthcare workers

During a pandemic, dentists face enormous challenges due to restrictions placed on their practice and the need to comply with biosafety measures. This study aimed to explore the impact of the COVID-19 pandemic and infection control measures on dentists and their practice in Jordan and the global implications for other primary healthcare workers. A qualitative exploratory study employing face-to-face or telephone interviews, was conducted with ten dentists from the 9^th May to 20^th September 2020. An inductive thematic approach to analysis was used identifying three themes, each with two accompanying subthemes: (1) Response to COVID-19 pandemic: (1a) Government response and (1b) People's response; (2) The effects of the pandemic and response measures: (2a) Impact on work and practice and (2b) Impact on personal and social life; (3) The unanticipated gains: (3a) Altruism and (3b) Leadership and change. Stringent infection control measures were implemented to slow the spread of the virus, however limited government support made implementation unsustainable and caused financial hardship. Lack of clear guidelines, changes in practice, social distancing measures, and altered social interactions, adversely impacted daily life, triggering mental distress. Misinformation influenced response to COVID safety measures. Despite the negatives, working during the pandemic reaffirmed dental professionals' roles and purpose, with strong leadership boosting morale. Education, adequate biosafety resources and clear guidelines or policies to support and sustain stringent infection control procedures are crucial in ensuring that measures are implemented to meet the safety requirements of the pandemic response. Promoting the well-being of the healthcare workforce is equally important. Finally, altruism and strong leadership among healthcare workers can contribute to a meaningful and humane pandemic response.

Knowledge, attitude, and behaviour of dentists working during the COVID-19 pandemic: A cross-sectional survey

BACKGROUND: The coronavirus disease 2019 (COVID-19) has immensely affected the world’s population at physical and psychosocial levels. Dentists are no different from other healthcare providers, as they are equally if not more exposed to the threat of getting infected. OBJECTIVE: To assess the experience and behavior of public and private sector dentists practicing during the COVID-19 pandemic and their knowledge about it. METHODS: A cross-sectional survey was conducted online by sharing google forms through email, WhatsApp, and Facebook. The survey included questions on the knowledge, attitude, and behavior of dentists practicing during COVID-19. The data was interpreted by SPSS 24 using a chi-square test, and a value of p < 0.05 was considered significant. RESULTS: A considerable number of general dentists (26.9%) and specialists (39.4%) adopted partial suspension of clinics. Restriction’s ease allowed 50.2% of the clinicians to resume their duties. 67.9% of the patients were medicated online during the lockdown phase. There was no significant difference regarding years of experience and willingness to treat/care (p-value 0.648). Personal protective equipment (PPE) was readily available for use in public or private practices, and the respondents agreed with its efficacy in protecting the operators. Compliance with PPE wear was 50% in all the respondents. CONCLUSION: The psychosocial repercussion of the pandemic continues to affect dental practices. Our attitude needs to improve as far as PPE is concerned, with regular training workshops and continuous updates of the developing Knowledge on COVID-19.

The prevalence of positive patients to COVID-19 rapid nasopharyngeal antigen testing in private dental practices

BACKGROUND

A quick diagnosis is crucial in effectively limiting the spread of SARS-CoV-2. The study aims to assess the prevalence of positive rapid tests in private dental practices.

METHODS

This is an observational study. 532 COVID-19 rapid nasopharyngeal antigen tests were carried out in the Veneto region of Italy. Patients of 4 dental practices in different cities (Caorle, Montebelluna, Treviso and Vicenza) were screened with a rapid test (Rapid Test COVID-19 Ag immunochromatographic assay, Techno Genetics) throughout November and December 2020. All the positive results from rapid tests were further investigated with a molecular test (PCR). All the patients tested showed no symptoms associated with SARS-CoV-2 infection and had already undergone triage and temperature measurement. In total 532 tests were taken: 202 in Caorle (Venice), 130 in Montebelluna (Treviso), 100 in Treviso, and 100 in Vicenza. Statistical analysis was carried with the computing environment R version 3.2.1 (R Foundation for Statistical Computing, Vienna, Austria). In particular, R was used for estimating the P value of the χ² test. The test was considered significant if the P value was lower or equal to 0.05.

RESULTS

The prevalence of the rapid tests that resulted positive was 7.14% (38 out of 532 in total, 22 out of 202 in Caorle, 6 out of 130 in Montebelluna, 4 out of 100 in Treviso and 6 out of 100 in Vicenza). Among these patients, 36 tested positive also with a molecular test (94.74%), in particular, 21 in Caorle, 5 in Montebelluna, 4 in Treviso, and 6 in Vicenza.

CONCLUSIONS

The prevalence of positive patients screened with a rapid test in private dental practices stands at 7.14% and it was confirmed in most of the patients with molecular tests. Therefore, in high-risk environments like dental practices, it is imperative to follow all the precautionary measures, and having every patient tested with a rapid test could be taken into consideration to limit the spread of COVID-19 infection.

The Impact of COVID-19 Pandemic on the Psychological Health and Dental Practice of Oral Healthcare Workers: A Scoping Review

This study aims to identify the impact of the COVID-19 pandemic on the psychological health and dental practice of oral health-care workers (OHCWs). The search for relevant literature was carried out online using PubMed, Web of science, and science direct databases from January 2020 to February 2021. Those articles were included that provided complete information about the impact of the COVID-19 pandemic on oral health-care workers during covid-19 and were original articles and reviews. Those articles were excluded from the current study that was not in English Language and involved case reports/book chapters/short communications. Finally, only 8 articles were selected for the scoping review considering that complete information regarding the provision of dental care in the time of COVID-19 was provided. Increased psychological distress (especially those with existing comorbidities) was noted among the OHCWs during this pandemic. They had enough knowledge about COVID-19 and showed concern regarding the future of dentistry. Either complete or partial closure of dental clinics had introduced financial constraints among them. However, the majority of them did not switch their profession. The institutions were not prepared for any such situation and no training was conducted to control the spread of COVID-19 infection. OHCWs are fully aware of the knowledge regarding COVID-19 and showed concerns for dentistry and dental health-care workers during this pandemic. Complete or partial closure of dental clinics has had adverse effects on the future of dentistry, economically as well as psychologically. Institutions need to upgrade and strengthen their systems to cater to any such situation efficiently. Proper counseling sessions should be conducted for the OHCWs to monitor, identify and treat the cases found.

The Provision of Dental Care to Post COVID-19 Survivors. A Concise Review

Aims

It has been reported that there are a certain percentage of COVID-19 patients who recover but suffer from devastating permanent organ damage or failure. Others suffer from long Covid syndrome, with prolonged symptoms that persist more than 12 weeks. However, there is scarcity of literature regarding the provision of dental treatment for these two groups of patients. This manuscript reviews the impact of multi-system involvement on the provision of dental care to these patients.

Materials and methods

A search of literature was done in PubMed-Medline and Scopus databases to review the available literature on COVID-19 impacts on pulmonary, cardiovascular, haematologic, renal, gastrointestinal, endocrine, and neurologic systems and respective management in dental clinical settings.

Results

The literature search from PubMed-Medline and Scopus databases resulted in 74 salient articles that contributed to the concise review on COVID-19 effects on pulmonary, cardiovascular, haematologic, renal, gastrointestinal, endocrine, and neurologic systems and/or its respective dental management recommendations.

Conclusions

This concise review covers the management of post COVID-19 patients with pulmonary, cardiovascular, haematologic, renal, gastrointestinal, endocrine, or neurologic system complications.

The dental office: A safe place against COVID19 and other future pandemics

Background

The pandemic caused by the spread of COVID19 generated throughout the world great changes in all areas of life. Social distancing was carried out very drastically in some countries, and even in the field of dental care, some countries prohibited the practice of dentistry.

Objective

To demonstrate that the dental office is safe regarding the possibility of contagion of Sars-Cov-2 as long as good biosecurity protocols are used.

Methods

A structured survey of 19 questions was applied to 103 patients who subsequently attended a periodontics and oral and maxillofacial surgery office in Mexico, to receive care from these specialties between April 2020 and July 2021. The questions posed in this survey were aimed at knowing the opinion of the patients regarding the measures that this establishment has for the prevention of the transmission of COVID19, as well as questions regarding the possible effects of attending this office in contagion of the disease from patients and their families.

Results

A total of 18 (17.5%) patients reported having suffered COVID19, and none reported that they fell ill after the consultation. None of the clinic's specialists and assistants have fallen ill with COVID-19 during the pandemic.

Conclusions

It is not necessary to suspend or condition dental care during times of pandemics such as what happened with COVID19, as long as strict safety protocols are observed within clinical facilities.

COVID-19 pandemic: multilevel dental technical guidelines based on new scientific evidence

The COVID-19 pandemic imposed restrictive measures on dentistry in different regions of the world, ranging from stoppage of care to only permission for urgent and emergency dental services. Thus, new biosafety guidelines for resuming activities, whether in single dental offices, large clinics or dental education activities, are urgently required. In this sense, herein, guidelines that incorporate common points of the main protocols found in the literature for the resumption of dental activities at their different levels, whether in the scope of care or education, are presented. Furthermore, we present the incorporation of measures that allow an increase in the level of biosafety, such as the control of the dental team, the inclusion in the history of conjunctivitis as a possible alert for COVID-19, and the use of the pulse oximeter to assess the risk of silent hypoxemia, which may indicate a complication of COVID-19. In addition, new perspectives for directing research and innovation for biosafety in dentistry are discussed.

Orthodontic Adolescent Patients’ Attitudes toward Protective Face Mask Wearing during the COVID-19 Pandemic

Background and Objectives: The COVID-19 pandemic led to restrictive measures, which aimed to limit the spread of the SARS-CoV-2 virus. These restrictions impacted all areas of life, including the activity of dental offices. For patients with orthodontic appliances, closing the dental offices was a major issue, as most orthodontic treatments last for more than a year and require regular checkups. The aim of this research was to assess the impact that the restrictive measures that were imposed during the COVID-19 pandemic, and, especially, wearing a face mask had on a sample of Romanian teenagers undergoing fixed orthodontic treatment. Material and Methods: The study group consisted of 277 orthodontic patients, with ages between 12 and 17.9 years, from North-Western Romania. They completed a 9-item questionnaire. The control group consisted of 231 participants, with ages between 12 and 17.9 years. They completed an 8-item questionnaire. Results: Most patients from the study group were not worried that wearing a protective face mask would hide their braces (never—49.5%; rarely—26.7%), and their desire to undergo an orthodontic treatment was not affected by the compulsoriness of face mask wearing (never—51.6%; rarely—26%). In contrast to that, in the control group, more than 50% of the participants were worried to some degree that wearing a protective face mask would hide their smile (occasionally—29.9%; frequently—18.2%; very frequently—2.2%). The majority of the participants from the study group did not consider interrupting the orthodontic treatment due to the COVID-19 pandemic (62.5%), and the majority of the participants from the control group did not consider not going to the dentist due to the COVID-19 pandemic (70.6%). Most of the participants from the study group were not happy that they had to wear a face mask, which covered their orthodontic appliances, during the orthodontic treatment (68.6%). The attitude was similar to that of the participants from the control group, who were not happy that they had to wear a face mask, that covered their smile (51.1%). In the study group, most patients did not want face mask wearing to continue to be compulsory, given the fact that their orthodontic appliances were no longer visible (52%). In the control group, the attitude was similar, with 48.1% of the participants not wanting face mask compulsoriness to be maintained. Conclusions: In conclusion, although, most patients would not like to continue wearing a face mask as a mandatory regulation, they were not concerned or negatively affected by wearing a protective face mask, even though face masks hid their braces.

Brazilian Primary and Secondary Public Oral Health Attention: Are Dentists Ready to Face the COVID-19 Pandemic?

OBJECTIVE

To investigate knowledge and practice of Brazilian public primary and secondary health care dentists during the coronavirus disease (COVID-19) pandemic.

METHODS

An online questionnaire with sociodemographic and COVID-19 knowledge questions was used.

RESULTS

A total of 4048 dentists working in the Brazilian public primary and secondary health care system were investigated; 4024 (99.41%) believe that COVID-19 can be transmitted through dental procedures. A fair level of COVID-19 symptoms knowledge by these dentists was observed (3.76±1.27 of 6.00), as well as the skepticism in personal protective equipment (3382; 83.55%) and biosafety procedures (3278; 80.98%) used as an efficient form of COVID-19 transmission prevention. Country region, performance of social distancing, dental specialty, the use of personal protective equipment, and biosafety preventive measures influenced the likelihood of dentists to perform dental treatment, either elective or urgent, during the COVID-19 pandemic.

CONCLUSION

The need of extra preventive barriers for dental treatment may bring an extra financial stress in the Brazilian public primary and secondary health care system, as well as in the patient-dentist relationship, which may have to be reframed. Internationally accepted public guideline policies regarding dental treatment safety, as well as the technological development of preventive tools, are needed to deal with the challenges brought by COVID-19.

Triage and urgent dental care for COVID-19 patients in the Hospital District of Helsinki and Uusimaa

OBJECTIVE

This paper describes and reports the patient-specific characteristics of an urgent dental care clinic for COVID-19 infected, suspected, exposed or quarantined patients from March to December 2020 in the Hospital District of Helsinki and Uusimaa, Finland.

MATERIAL AND METHODS

The triage and the treatment protocol were established based on the scientific data. Patient files were evaluated from the hospital district's electronic medical record system. IBM SPSS software was used for statistical analysis.

RESULTS

There were 1114 consultations and 257 visits at the clinic. Most of the patients were generally healthy with mean age of 35, had toothache and were suspected to be SARS-CoV-2 positive. Seventeen of the patients received positive tests for COVID-19 infection. The main treatment was tooth extraction, mostly due to caries. Statistically significant differences between COVID-19 infected and other patients occurred in age (45 vs 34 years-of-age, p = .009) and number of teeth (25 vs 28, p = .031). No SARS-CoV-2 infection transmission chains were traced to the clinic.

CONCLUSION

During the challenging pandemic time, patients were carefully screened by specialists in clinical dentistry and treated safely and effectively. Patient-specific characteristics revealed no differences between COVID-19 infected and other patients in terms of symptoms or treatment needs.

Infection Risk Prediction Model for COVID-19 Based on an Analysis of the Settlement of Particles Generated during Dental Procedures in Dental Clinics

Background

The health emergency declaration owing to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has drawn attention toward nosocomial transmission. The transmission of the disease varies depending on the environmental conditions. Saliva is a recognized SARS-CoV-2 reservoir in infected individuals. Therefore, exposure to fluids during dental procedures leads to a high risk of contagion.

Objective

This study aimed to develop an infection risk prediction model for COVID-19 based on an analysis of the settlement of the aerosolized particles generated during dental procedures.

Materials and Methods

The settlement of aerosolized particles during dental aerosol-generating procedures (AGPs) performed on phantoms was evaluated using colored saliva. The gravity-deposited particles were registered using a filter paper within the perimeter of the phantom head, and the settled particles were recorded in standardized photographs. Digital images were processed to analyze the stained area. A logistic regression model was built with the variables ventilation, distance from the mouth, instrument used, area of the mouth treated, and location within the perimeter area.

Results

The largest percentage of the areas stained by settled particles ranged from 1 to 5 µm. The maximum settlement range from the mouth of the phantom head was 320 cm, with a high-risk cutoff distance of 78 cm. Ventilation, distance, instrument used, area of the mouth being treated, and location within the perimeter showed association with the amount of settled particles. These variables were used for constructing a scale to determine the risk of exposure to settled particles in dentistry within an infection risk prediction model.

Conclusion

The greatest risk of particle settlement occurs at a distance up to 78 cm from the phantom mouth, with inadequate ventilation, and when working with a high-speed handpiece. The majority of the settled particles generated during the AGPs presented stained areas ranging from 1 to 5 µm. This model was useful for predicting the risk of exposure to COVID-19 in dental practice.

Improving safety in dental practices during the COVID-19 pandemic

Coronavirus disease 2019 (COVID-19) is caused by a novel coronavirus, known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It originated from the Chinese city of Wuhan and very quickly became a challenging public health problem. On 11 March 2020, the World Health Organization termed this potentially deadly disease a pandemic due to its rapid spread in various parts of the world, giving rise to international health emergencies. This virus is transmitted from human to human in the form of respiratory droplets, and in specific circumstances, airborne transmission may occur. Additional sources of exposure for dentists include blood and infected sharps. Due to the contagious nature of COVID-19 many health care providers have also been disproportionately affected, such as physicians, dentists, nurses, and paramedical staff. Dentists and dental staff are at high risk of cross-infection due to their nature of work. Therefore, they face a dual challenge in protecting themselves and their patients from infection transmission while ensuring that patients receive urgent dental care. In this review, the authors highlight the epidemiology, modes of cross-infection, and recent data on SARS-CoV-2 related to dental practice. The primary purpose is to make dental health care providers aware of the pathophysiology of COVID-19 and to increase their preparedness and understanding of this challenge, which will aid in controlling transmission. The information collected will be useful for the dental community in providing effective patient management through evidence-based recommendations for infection control and disinfection protocols.

Comprehensive Knowledge and Preparedness among Dental Community to Confront COVID-19-A Multicentric Cross-Sectional Study

The healthcare policy changes need to be updated for better management of the COVID-19 outbreak; hence, there is an urgent need to understand the knowledge and preparedness of healthcare workers regarding the infection control COVID-19. Therefore, the present study aims to assess the knowledge and preparedness towards COVID-19 among dentists, undergraduate, and postgraduates in dental universities one year after the COVID-19 outbreak. The multi-centric cross-sectional study was conducted by evaluating 395 structured, pre-coded, and validated questionnaires obtained from sample units comprising full-time dental students (undergraduates, interns, and postgraduates) and dentists who were currently in practice and who were able to comprehend the languages English or Arabic. The first part of the questionnaire included questions related to demographic characteristics. The second part of the survey consisted of questions that address knowledge concerning COVID-19. The third part of the survey addressed questions based on the preparedness to fight against COVID-19 including sharp injuries during this period. Comparing the knowledge scores of dentists, dental undergraduates, and postgraduates using the ANOVA test, dentists have higher knowledge and preparedness scores than postgraduates and undergraduates (p-value < 0.05). Univariate logistic regression analysis demonstrated that undergraduates and postgraduates were 2.567 and 1.352 times less aware of the personal protective measures against COVID-19 than dentists, respectively. Dentists had the comparatively better perception in knowledge and awareness of COVID-19 than undergraduates and postgraduates.

Impact of COVID-19 on Dentistry

Pandemic situations always impose devastating aftereffects on communities and cause chronic damaging effects on the healthcare system. Novel coronavirus disese-2019 (COVID-19) which has originated in China (Wuhan) is nowadays an emerging threat to public health across the world. It is spreading worldwide so rapidly and has started infecting people in all possible ways. Several dental care facilities in affected countries are completely closed or have been only providing minimal treatment for emergency cases since the whole lockdown has been announced. However, in some affected countries, they are still providing regular dental treatment. This discrepancy could be because of the dearth of proper awareness, knowledge, protocol, or guidelines.

QUALITY APPRAISAL OF CLINICAL PRACTICE GUIDELINES ON PROVISION OF DENTAL SERVICES DURING THE FIRST MONTHS OF THE COVID-19 PANDEMIC

Objectives

To evaluate the quality of clinical practice guidelines (CPGs) on dental services provision during the first months of the COVID-19 pandemic.

Materials and methods

We systematically searched in MEDLINE, EMBASE, LILACS, Epistemonikos, Trip databases, websites of CPG developers, compilers of CPGs, scientific societies and ministries of health to identify documents with recommendations intended to minimize the risk of COVID-19 transmission during dental care. Reviewers independently and in duplicate assessed the included CPGs using the AGREE II instrument. We calculated the standardized scores for the 6 domains and made a final recommendation about each CPG. The inter-appraiser agreement was assessed using the intraclass correlation coefficient (ICC).

Results

Twenty-three CPGs published were included. Most of the CPGs were from America (n = 15) and Europe (n = 6). The overall agreement between reviewers was very good (ICC = 0.93; 95%CI 0.87-0.95). The median score for each domain was the following: Scope and purpose 67% (IQR 20%); Stakeholder involvement 33% (IQR 14%); Rigour of development 13% (IQR 13%); Clarity of presentation 64% (IQR 31%); Applicability 19% (IQR 17%) and Editorial independence 8% (IQR 8%). Twenty two guidelines were not recommended by the reviewers. Only one of the CPGs was recommended with modifications. The median overall rate was 3 (IQR 1). All CPGs were classified as low quality.

Conclusions

The overall quality of CPGs on dental services provision during the first months of the COVID-19 pandemic was low, which makes its implementation difficult for clinicians and policy makers. Therefore, it is critical that developers are transparent and forthcoming about the difficulties that have arisen during the CPG development process.

Evaluation of the economic impact of COVID-19 on Brazilian private dental clinics: A cross-sectional study

BACKGROUND

The changes in dental care in the face of the COVID-19 pandemic resulted in the need for greater financial investment by dentists in biosafety measures and increase in the costs of dental consultations.

OBJECTIVE

To evaluate the economic impact of the COVID-19 pandemic on dental practices in private clinics in Brazil.

METHODS

A cross-sectional study was carried out, using an online questionnaire indexed in Google Forms, and distributed among dentists. The data obtained were analyzed using the IBM SPSS 25.0 software, evaluating the factors associated with strong or very strong impact on the participants' income and the factors that motivated the dentists to look for a credit line. Multiple logistic regression models were constructed to identify the associated factors. Variables with p <  0.05 were considered statistically significant.

RESULTS

Most participants were female, with a median age of 35 years. Dentists who are most concerned about their professional future (OR = 3.134; 95% CI: 1.804-5.445), who have longer office hours (OR = 2.056; 95% CI: 1.198-3.529), who had the greatest impact on the flow of patients (OR = 16.358; 95% CI: 9.408-28.443) and in need of investing in infrastructure (OR = 1.756; 95% CI: 1.014-3.041), had the greatest impact on monthly earnings.

CONCLUSIONS

The pandemic and the new biosafety recommendations for care during this period had a negative impact on the income of Brazilian dental offices and increased the chance of seeking credit to alleviate the financial deficit.

Management of Dental School During the COVID-19 Pandemic: Application of Intervention Mapping

Background: Coronavirus Diesease-2019 (COVID-19) outbreak has led to the suspension of the activities of dental schools. Therefore, reorganizing clinical settings and supporting services as quickly as possible has received much attention to reopen dental schools. The present study aimed to evaluate the applicability of the Intervention Mapping (IM) approach for designing, implementing, and evaluating an intervention program to prevent and control COVID-19 in dental schools. Methods: Following the IM protocol, six steps were completed in the planning and development of an intervention, targeting, and management of Dental School during the COVID-19 pandemic. Results: The information obtained from the needs assessment revealed that the COVID-19 outbreak prevention was associated with the use of personal protective equipment by all target groups, infection control measures taken in the environment, preparation of the environment and equipment, changes in the treatment plan according to the COVID-19 pandemic, changing the admission process of patients, and reduction of attendance of target groups in the school are linked with. In this study, determinant factors affecting the COVID-19 prevention at the individual level were identified based on the Protection Motivation Theory (PMT). In this program, various methods, such as presentation of information, modeling role, and persuasion measures, were utilized and the practical programs included educational films and group discussions implemented. Conclusions: Our findings indicated that intervention in dental environments on the basis of the IM process can develop a comprehensive and structured program in the dental school and hence can reduce the risk of the COVID-19 infection.

Knowledge, Attitude, and Practices of Dentists in Caribbean Countries during the COVID-19 Pandemic: A Multicenter Cross-Sectional Study

Background: The COVID-19 pandemic has affected dentists globally, both financially and mentally. This study aimed to determine the knowledge, attitude, and practices of dentists in Caribbean countries during the COVID-19 pandemic. Methods: A non-probability sample was obtained from dentists in more than ten different Caribbean countries. They were invited to complete a self-reported questionnaire, which was conducted from December 2020 to March 2021. Ethics approval was sought and an exemption was received from the UWI ethics committee. Results: One hundred and fifty-two dentists responded. More than one-third (38.8%) were in the >35–45 age group, and 58.6% were females. Most (84.9%) were general dentists and 75% were stressed by the COVID-19 situation with 80.9% being affected financially. The majority, 94.7%, believed that the highest risk of transmission of COVID-19 was via aerosol-generating procedures and 87.5% were worried about contracting it clinically. The majority (69.1%) were willing to receive the vaccine, the main reason reported for vaccine hesitancy was due to the possible side effects (35.3%). Most (75%) consumed alcohol. When the locus of control was determined, 54.6% felt they were in control of protecting themselves while 52% felt that external factors controlled their lives. Conclusions: The findings suggest that most dentists in the Caribbean were knowledgeable about COVID-19 and followed current guidelines in their practice and were willing to receive the vaccine.

Periodontal Management during COVID-19 Pandemic: Mini Review

A few cases of pneumonia were reported by Wuhan Municipal Health Commission in Wuhan, Hubei Province, Republic of China and this mysterious pneumonia was recognized as novel coronavirus disease (COVID-19) in the course of time on 31 December 2019. Based on the literature knowledge, COVID-19 outbreak was came into existence through an animal-to-human transmission, then continued human-to-human diffusion. Especially dentists among the medical professionals are at high-risk group of SARS-CoV-2 virus contamination because of several routine dental procedures having the risk to convey the SARS-CoV-2 virus via droplets and close contact. In this mini review, it was aimed to give information about patient management during COVID-19 pandemic for dental practitioners, periodontologists and dental hygienists.

COVID-19 and Its Repercussions on Oral Health: A Review

In 2019, a new type of coronavirus, SARS-CoV-2, the causing agent of COVID-19, was first detected in Wuhan, China. On 11 March 2020, the World Health Organization declared a pandemic. The manifestations of COVID-19 are mostly age-dependent and potentially more severe in cases with involved co-morbidities. The gravity of the symptoms depends on the clinical stage of the infection. The most common symptoms include runny nose and nasal congestion, anosmia, dysgeusia or hypogeusia, diarrhea, nausea/vomiting, respiratory distress, fatigue, ocular symptoms, diarrhea, vomiting, and abdominal pain. These systemic conditions are often accompanied by skin and mucosal lesions. Oral lesions reported in patients with COVID-19 include: herpex simplex, candidiasis, geographic tongue, aphthous-like ulcers, hemorrhagic ulcerations, necrotic ulcerations, white hairy tongue, reddish macules, erythematous surfaces, petechiae, and pustular enanthema. It is still unclear if these manifestations are a direct result of the viral infection, a consequence of systemic deterioration, or adverse reactions to treatments. Poor oral hygiene in hospitalized or quarantined COVID-19 patients should also be considered as an aggravating condition. This narrative review is focused on presenting the most relevant data from the literature regarding oral manifestations related to SARS-CoV-2, as well as the challenges faced by the dental system during this pandemic. A routine intraoral examination is recommended in COVID-19 patients, either suspected or confirmed, as, in certain cases, oral manifestations represent a sign of severe infection or even of a life-threatening condition. It is our belief that extensive knowledge of all possible manifestations, including oral lesions, in cases of COVID-19 is of great importance in the present uncertain context, including new, currently emerging viral variants with unknown future impact.

Emotional well-being of dentists and the effect of lockdown during the COVID-19 pandemic: A nationwide study

BACKGROUND

Lockdown in India might have adverse effects on the emotional health of the dental professionals; hence, the aim of the present study was to determine the impact of various factors on emotional well-being of dental professionals due to the effect of lockdown during COVID-19.

MATERIALS AND METHODS

It was a cross-sectional, descriptive, questionnaire study conducted on dentists in India during April 2020. Sampling technique was convenient sampling, and sampling frame was all the dental professionals in India. The questionnaire was prepared online using Google Forms, and the link was generated which was shared among as many dentists accessible as possible, with the help of message, mails, and WhatsApp. The questionnaire consists of questions on Demographic details, practice, and emotional well-being. A total of 1844 dental professionals in 14 states in India responded. The statistical analysis was done using SPSS version no. 20. IBM SPSS version 20.0 (IBM; Armonk, New York USA) Descriptive statistics and multinomial regression test was applied.

RESULTS

Majority of study participants (1096 [59.4%]) belonged to age group of 26-35 years. Emotional well-being score of 1206 (65.4%) dental professionals in the times of COVID-19 outbreak was poor with score between 26 and 78. It was assessed that males have significantly (P = 0.00**) (P < 0.001**) (**highly significant) poorer emotional well-being 0.085 (0.829-1.429) compared to females. Married dental professionals - 0.023 (0.011-1.221) had significantly better (P = 0.05*) emotional well-being than others.

CONCLUSION

Emotional well-being score of majority of dental professionals in the times of COVID-19 outbreak was poor. Gender, marital status, socioeconomic status, years of experience, practicing in clinic, and average number of patients seen per month before lockdown have significant impact on emotional wellbeing of dental professionals.

Recommendations for Safe Dental Care: A Systematic Review of Clinical Practice Guidelines in the First Year of the COVID-19 Pandemic

In the context of a pandemic, the rapid development of clinical practice guidelines (CPGs) is critical to guide dental staff towards the safe provision of dental care; detailed knowledge of the recommendations will help to achieve the intended results. We carried out a systematic review of the recommendations in clinical practice guidelines (CPGs) on the provision of dental care issued during the first year of the COVID-19 pandemic. A systematic database search was performed in MEDLINE, EMBASE, LILACS, Epistemonikos, and Trip databases to identify documents with recommendations intended to minimize the risk of COVID-19 transmission during dental care. The selection process and data extraction were carried out by two researchers independently. The majority of CPGs recommended the use of rubber dam, high-volume evacuator, mouthwash prior to dental care, four-handed work, and mechanical barriers. The use of aerosol-generating equipment should be avoided whenever possible. In aerosol-generating procedures, the use of a N95 respirator (or similar) is recommended, in addition to a face protector, an impermeable disposable apron/gown, a cap, and gloves. The CPGs developed during the first year of the pandemic offer recommendations which guide dental staff in providing safe dental care, minimizing exposure to SARS-CoV-2 and reducing the risk of COVID-19 infection in the clinical environment. Such recommendations must, however, be updated as new evidence arises.

Knowledge and Attitude towards Dental Clinical Practice Related to COVID-19 Pandemic among Dental Interns in Saudi Arabia

Background:

The newly emerged pandemic has created many dilemmas in dental clinical practice all over the world. Most of the practicing dentists and dental students are at higher risk of getting infected and transmitted the disease. The study aimed to explore the knowledge and attitudes among dental interns in Saudi Arabia related to the COVID-19 pandemic.

Materials and Methods:

An online questionnaire survey was carried out among dental students pursuing their internship at different universities in Saudi Arabia. A combination of convenience and snowball sampling was used to identify interns from each province of the Kingdom. The questionnaire was validated and pretested, which recorded the knowledge, attitude, and concerns related to dental practice and COVID-19.

Results:

The knowledge related to COVID-19 and its importance in clinical dental practice was below average among dental interns, and only 22.2% gave a correct response to all questions. About 80.8% and 85% of the dental students were worried about contracting the infection during dental practice and transmitting it to family and friends, respectively.

Conclusion:

Dental students showed satisfactory knowledge, attitude, and practices related to COVID-19, and most of them were aware and adhering to the preventive guidelines set by the ministry of health.

The Impact of COVID-19 on Dental Research in Educational Settings: What are the Opportunities?

The COVID-19 pandemic has significantly impacted dental education and research activities, creating challenges for students, educators, and health-care professionals. The unfolding crisis has shed the light on how technology can facilitate not only the delivery of dental education and improving access to dental care but also new and ongoing research. While dental schools worldwide have re-structured their policies and curricula in terms of incorporating appropriate methods of distance learning, this now needs to be applied to dental research where appropriate. By conducting a "strengths, weaknesses, opportunities, and threats" analysis and describing the authors' experiences, here we discuss the impact of the pandemic on various aspects of dental research to provide a timely perspective on dental research activity in academic institutions to help achieve research outcomes despite the pandemic's impact.

COVID-19, A new challenge in the dental practice

BACKGROUND

This review was conducted in order to learn the latest information about how to prevent cross-infection of COVID-19 in dentistry. The aim of this study is offer a clinical protocol to reduce the risk of infection of COVID-19 in dental settings.

MATERIAL AND METHODS

We carried out a review based on the PRISMA guide (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). We used the following three databases: PubMed, Embase and Scopus. The search strategy was performed in the three databases applying the search terms "COVID-19 AND dental", "COVID-19 AND dentistry", selecting human studies published from November 2019 to May 2020. English publications regarding COVID-19 as the central topic of the research were eligible for inclusion, regardless of study design. There are very few published studies on the association between COVID-19 and dentistry, for that reason we also included the English abstract of two studies written in Chinese. The following exclusion criteria were established: animal studies and in vitro studies.

RESULTS

The search identified a total of 212 articles, of which 54 were preselected, and 23 were finally included in the review on the basis of the inclusion and exclusion criteria. We collected all the information about routes of general and oral infection, dental patient evaluation and cross-infection control in Dental Clinic in the selected studies.

CONCLUSIONS

Cross infection in the dental clinic involve a very important risk due to the return to dental settings after periods of social isolation of the population after the epidemic outbreak of SARS-CoV-2. Therefore, we must take adequate and sufficient security measures to protect the patients and the dental clinic staff. Key words:COVID-19, COVID-19 cross infection risk, COVID-19 prevention in Dentistry, COVID-19 in Dental Clinic.

Awareness of COVID-19 and the Dental Implications of its Oral Manifestations among Dental Health Practitioners in Nigeria

Background

There are many aspects of COVID-19 that are related to dental practice. Hence, this study aimed to assess the level of awareness of COVID-19 concerning its symptoms, transmission and prevention and the dental implications of its oral manifestations among dentists in Nigeria.

Methodology

This is a cross-sectional study that sampled dentists who work in Nigeria regardless of their place of work with an online questionnaire using Google forms to collect the data. The questionnaire was anonymous to maintain the privacy and confidentiality of all information collected in the study. The survey was a structured questionnaire divided into three sections: Dentists' demographics, knowledge of the disease and dental implications of COVID-19.

Results

This study included 206 dentists practising in Nigeria, with 126 (61.2%) males and 80 (38.8%) females. A total of 191 (92.7%) dentists perceived COVID-19 as highly contagious and deadly. Almost all the participants (n=205, 99.5%) were knowledgeable about the mode of transmission of the disease through respiratory droplets. A total of 204 (99.0%) affirmed that dental practitioners were at risk of becoming infected with COVID-19. About 84.5% reported that salivary glands can serve as a potential reservoir for COVID-19.

Conclusion

The awareness of COVID-19 concerning the mode of transmission, symptoms and prevention among the dental professionals was encouraging. This would lead to enhanced infection control in dental settings. The majority of the participants reported that saliva can be used as a promising non-invasive specimen for diagnosis, monitoring and infection control in patients with COVID-19.

Comparison of the use of personal protective equipment and infection control in dentists and their assistants before and after the corona crisis

BACKGROUND

Coronavirus disease 2019 is a new viral outbreak in the world. Dentists and their assistants are at greatest risk of exposure to the virus, due to close contact with patients and dealing with aerosols. Hence, the aim of this study was to compare the use of personal protective equipment (PPE) and supplementary protective equipment (SPE) and observance of the principles of infection control (PIC) in dentists and their assistants before and after the corona crisis.

MATERIALS AND METHODS

This cross-sectional study was conducted using an online survey from May 6 to 20, 2020. Convenience sampling was used to select individuals. The questionnaire, consisting of four general categories about the use of PPE and SPE and the observance of PIC by dentists and their assistants before and after corona crisis, was registered at Porsline website (https://survey.porsline.ir/s/KUt7VQB). Frequencies in each subcategory were calculated and comparisons were done using Chi-square test, Fisher's exact test, and paired sample t-test. A P < 0.05 was considered statistically significant.

RESULTS

There were significant differences in the frequency of use of PPE by dentists before and after corona crisis for oral and dental examination and also dental procedures (P < 0.001). There were significant differences in the frequency of use of SPE and observance of PIC before and after corona crisis, except for different types of suction types (P = 0.22), dental handpiece (P = 0.66), and dental unit (P = 1). There were significant differences in the frequency of use of PPE by dental assistants before and after corona crisis (P < 0.001).

CONCLUSIONS

Although the frequency of use of PPE and observance of PIC increased among dentists and their assistants, this increase is not sufficient, especially for dental assistants, and a higher level of use of PPE and PIC observance in face of highly contagious and life-threatening viruses such as corona is required.

Awareness and Practice of COVID-19 Precautionary Measures Among Healthcare Professionals in Saudi Arabia

Objective

Healthcare workers (HCWs) are the backbone of the healthcare system and a skilled and healthy workforce is vital during a health crisis, such as the present coronavirus disease 2019 (COVID-19) pandemic. Healthcare workers are at higher risk of exposure to and transmission of the severe acute respiratory coronavirus-2 (SARS-CoV-2). Hence, HCWs should possess good knowledge and attitudes toward COVID-19 to protect not only themselves but also their colleagues, families and the larger community. Thus, the current study aims to assess the knowledge and practice of protective measures by HCWs in Saudi Arabia during the first wave of the COVID-19 pandemic to identify awareness of the disease, potential trends and associated predictors.

Methods

A cross-sectional, web-based study was conducted among HCWs about knowledge related to COVID-19 and practice of protective measures, such as social distancing and use of personal protective equipment (PPE) during the pandemic. A Fisher exact test and one-way analysis of variance (ANOVA) were used to investigate the level of association among variables.

Results

A total of 674 HCWs were recruited in the study (51.8% male, 42.7% aged 28–37 years old and 52% specialists). The Saudi Ministry of Health (MoH) was the main source of knowledge for most of the HCWs (89%) followed by the WHO (44.5%) and social media (42.3%). Washing hands before touching the face was the most selected choice (97.9%) as a precautionary method to limit SARS-CoV2 transmission. Most of the HCWs (74.6%) scored low for staying at home while the majority (71.2%) showed a high practice of personal protective methods, with pharmacists and general physicians scoring the highest.

Conclusion

Saudi HCWs showed high knowledge and practice of protective measures for COVID-19. Good knowledge correlates with adoption of appropriate practices to prevent spread of infection. The current findings highlight the importance of interventions such as tailored education and training courses for those with low scores to improve overall knowledge and practice.
