The incidence of COVID-19 among dentists practicing in the community in Canada: A prospective cohort study over a 6-month period

BackgroundOral health care settings carry a potentially high risk of causing cross-infection between dentists and patients and among dental staff members due to close contact and use of aerosol-generating procedures. The authors aimed to estimate COVID-19 incidence rates among Canadian dentists over a 6-month period.MethodsThe authors conducted a prospective cohort study of 644 licensed dentists across Canada from July 29, 2020, through February 12, 2021. An online questionnaire, adapted from the World Health Organization’s Unity Studies protocols for assessment of COVID-19 risk among health care workers, was used to collect data on self-reported severe acute respiratory syndrome coronavirus 2 infections every 4 weeks. A bayesian Poisson model was used to estimate the incidence rate and corresponding 95% credible intervals (CIs).ResultsMedian age of participants was 47 years; most participants were women (56.4%) and general practitioners (90.8%). Median follow-up time was 188 days. Six participants reported COVID-19 infections during the study period, giving an incidence rate of 5.10 per 100,000 person-days (95% CI, 1.86 to 9.91 per 100,000 person-days). The incidence proportion was estimated to be 1,084 per 100,000 dentists (95% CI, 438 to 2,011 per 100,000 dentists) and 1,864 per 100,000 people (95% CI, 1,859 to 1,868 per 100,000 people) in the Canadian population during the same period.ConclusionsThe low infection rate observed among Canadian dentists from July 29, 2020, through February 12, 2021, should be reassuring to the dental and general community.Practical ImplicationsAlthough the infection rates were low among Canadian dentists, it is important to continue to collect disease surveillance data.     

Estimating COVID-19 prevalence and infection control practices among US dentists

BackgroundUnderstanding the risks associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission during oral health care delivery and assessing mitigation strategies for dental offices are critical to improving patient safety and access to oral health care.MethodsThe authors invited licensed US dentists practicing primarily in private practice or public health to participate in a web-based survey in June 2020. Dentists from every US state (n = 2,195) answered questions about COVID-19–associated symptoms, SARS-CoV-2 infection, mental and physical health conditions, and infection control procedures used in their primary dental practices.ResultsMost of the dentists (82.2%) were asymptomatic for 1 month before administration of the survey; 16.6% reported being tested for SARS-CoV-2; and 3.7%, 2.7%, and 0% tested positive via respiratory, blood, and salivary samples, respectively. Among those not tested, 0.3% received a probable COVID-19 diagnosis from a physician. In all, 20 of the 2,195 respondents had been infected with SARS-CoV-2; weighted according to age and location to approximate all US dentists, 0.9% (95% confidence interval, 0.5 to 1.5) had confirmed or probable COVID-19. Dentists reported symptoms of depression (8.6%) and anxiety (19.5%). Enhanced infection control procedures were implemented in 99.7% of dentists’ primary practices, most commonly disinfection, COVID-19 screening, social distancing, and wearing face masks. Most practicing dentists (72.8%) used personal protective equipment according to interim guidance from the Centers for Disease Control and Prevention.ConclusionsCOVID-19 prevalence and testing positivity rates were low among practicing US dentists. This indicates that the current infection control recommendations may be sufficient to prevent infection in dental settings.Practical ImplicationsDentists have enhanced their infection control practices in response to COVID-19 and may benefit from greater availability of personal protective equipment.

COVID-19 vaccine hesitancy and reasons for or against adherence among dentists

BackgroundCOVID-19 has spread widely among health care workers. Oral health care workers have an increased risk of being infected owing to dental practice characteristics. New, effective vaccines against COVID-19 have been approved for use. The authors aim was to evaluate intentions to be vaccinated against COVID-19 in a population of dentists and identify factors associated with their intentions.MethodsThe authors conducted an anonymous online survey among 761 dentists enrolled at the Board of Physicians and Dentists of the District of Monza Brianza, Monza, Italy. The authors collected data on demographic characteristics, influenza vaccine uptake, COVID-19 history, vaccine attitudes, and specific reasons for their intentions to be vaccinated against COVID-19 or not.ResultsOverall, 421 dentists completed the survey. More than 82% of the participants declared their intention to be vaccinated against COVID-19. The multivariate logistic regression model reported a positive association with receiving the influenza vaccine in the 2020-2021 influenza season (odds ratio, 5.15; 95% CI, 2.14 to 12.39) and a negative association with receiving a diagnosis of COVID-19 previously (odds ratio, 0.32; 95% CI, 0.15 to 0.66). The participants’ main reason for supporting vaccination was to protect their family and friends (87%) and their main reason for opposing vaccination was the lack of information (39%).ConclusionsIt is fundamental to consider vaccine hesitancy in health care workers and address it properly because they must provide recommendations to patients and promote adherence to vaccination programs.Practical ImplicationsThe vaccination of dental practitioners should be prioritized owing to the high risk related to dental practice.     

Barriers to and facilitators of opioid prescribing by dentists in the United States: A qualitative study

BackgroundDentists in the United States frequently prescribe opioids for dental-related pain, although evidence shows superior efficacy of nonopioids for pain management. A national sample of US dentists was interviewed to understand the barriers and facilitators to opioid prescribing.MethodsSemistructured one-on-one telephone interviews were conducted with dentists sampled from the 6 regions of The National Dental Practice-Based Research Network. Responses were coded into the domains of the Capability, Opportunity and Motivation Model of Behavior. Potential behavior change interventions were identified for targeted themes.ResultsSeventy-three interviews were qualitatively analyzed. Most of those interviewed were general dentists (86.3%) and on average (SD) were in practice for 24.3 (13.0) years. Ten themes were identified within the Capability, Opportunity and Motivation Model of Behavior. Dentists’ knowledge of opioid risk, ability to identify substance use disorder behavior, and capability of communicating pain management plans to patients or following clinic policies or state and federal regulations were linked with judicious opioid prescribing. Dentists reported prescribing opioids if they determined clinical necessity or feared negative consequences for refusing to prescribe opioids.ConclusionsDentists’ opioid decision making is influenced by a range of real-world practice experiences and patient and clinic factors. Education and training that target dentists’ knowledge gaps and changes in dentists’ practice environment can encourage effective communication of pain management strategies with patients and prescribing of nonopioids as first-line analgesics while conserving opioid use.Practical ImplicationsIdentified knowledge gaps in dentistry can be targets for education, clinical guidelines, and policy interventions to ensure safe and appropriate prescribing of opioids.     

COVID-19 vaccine acceptance and hesitancy among dental and medical students

BackgroundDental students (DS) and medical students (MS) are exposed to COVID-19. It is important to achieve high COVID-19 vaccination coverage rates in both of these groups. The authors developed a survey to assess COVID-19 vaccine hesitancy among MS and DS.MethodsThe authors conducted the study at 3 US dental schools and 1 US medical school using an online survey that assessed previous immunization behavior, attitudes about and perceptions of COVID-19 vaccines, and personal experience with COVID-19.ResultsA total of 248 DS and 167 MS completed the survey. Forty-five percent of DS and 23% of MS were hesitant about receiving the COVID-19 vaccine. Results of bivariate analyses found that MS were 2.7 times more likely than DS to receive the vaccine (odds ratio, 2.74; 95% CI, 1.76 to 4.31; P = .0001). Although DS were more likely than MS (P < .05) to have had COVID-19 and to personally know someone who had COVID-19, MS were more likely to agree with mandates and trust information about the vaccines. In multivariable analyses, after controlling for demographic variables, experience with COVID-19, and personal vaccination behaviors, being a MS or DS was no longer predictive of willingness to get the vaccine.ConclusionsThese results highlight the need for profession-specific curricula designed to enhance student knowledge about the vaccines and vaccine counseling skills.Practical ImplicationsThe American Dental Association supports dentists administering vaccines, including the COVID-19 vaccines. Dentists and DS should be willing to receive the vaccines themselves. Education about the vaccines is needed to improve uptake.     

Changes in dental care use patterns due to COVID-19 among insured patients in the United States

BackgroundDemand for dental services has been known to be linked closely to dental insurance and disposable income. Widespread economic uncertainty and health systems changes due to COVID-19 thus may have a significant impact on dental care use.MethodsUsing deidentified dental practice management data from 2019 and 2020, the authors observed variations in dental care use among insured patients since the COVID-19 outbreak (during the period of practice closure and after the reopening) by patient age, procedure type, insurance type, practice size, geographic area, and reopening status. The authors examined whether the rebound in procedure volumes at dental practices can be explained by county-level characteristics using hierarchical regression models.ResultsAlthough dental care use among privately insured patients fully rebounded by August 2020, use still remained lower than the prepandemic level by 7.54% among the publicly insured population. Demand for teledentistry increased 60-fold during practice closure. Geographic characteristics—such as median household income, percentages of rural or Black populations, and dental care professional shortage designations—were associated significantly with the number of procedures performed at dental practices.ConclusionsAs a result of COVID-19, dental practices experienced substantial decreases in procedure volume, particularly among patients covered by public insurance or residing in underserved areas.Practical ImplicationsDuring economic downturns, state health officials should be encouraged to adopt policies to expand access to oral health care for vulnerable populations via oral health promotion strategies and increasing the supply of dentists or midlevel dental care providers in underserved areas.     

Dentists’ knowledge,attitudes, and professional behavior toward the COVID-19 pandemic: A multisite survey of dentists’ perspectives

BackgroundCOVID-19 continues to affect the dental community worldwide. The authors conducted a cross-sectional electronic study using a multisite survey to examine dentists’ knowledge, attitudes, and professional behavior toward COVID-19 and the affect on their livelihood.MethodsA questionnaire was circulated via e-mail and social media platforms to dentists in North America, Europe, Eastern Mediterranean, and Western Pacific regions. It covered demographic characteristics and questions about the COVID-19 outbreak related to dentists’ levels of comfort for preventive and safety measures, provision of treatment, affect on work, and financial implications. Responses were tabulated and analyzed by means of χ² or Fisher exact test. Mann-Whitney and Kruskal-Wallis tests were used to compare means. P < .05 was considered significant.ResultsA total of 1,251 dentists responded. General dentists represented 63.9% of the respondents and 62.5% worked in private practice. The global score for level of comfort with the preventive measures and provisions of treatment during the COVID-19 pandemic was low (14 of 30), and differences between regions were significant (P < .01); dentists working in private practice and general dental practitioners were less comfortable (P < .01).Conclusions and Practical ImplicationsThe respondents reported a lack of preparedness to confront a highly infectious respiratory disease. A new level of protective armamentarium in the dental operatory and updated operational guidance and policies are required, necessitating educators and regulators to ensure the delivery of knowledge and skills to oral health care providers. Dentists need to address the sustainability of their practices and have a robust business plan.     

A survey on radiation exposure reduction methods including rectangular collimation for intraoral radiography by pediatric dentists in the United States

BackgroundThe authors conducted a survey of the American Academy of Pediatric Dentistry (AAPD) to determine awareness of the Image Gently Campaign in Dentistry (IGCD) and to ascertain radiologic practices, including radiation dose-reduction strategies such as rectangular collimation.MethodsAn institutional review board approved an electronic survey sent to 7,087 AAPD members covering practitioner demographic characteristics, radiographic techniques, and dose-reduction practices, including rectangular collimation. Responses were tabulated and analyzed using binomial tests, χ² tests, and Fisher exact tests.ResultsA total of 1,124 pediatric dentists or residents in pediatric dentistry responded, (response rate 16%, margin of error ± 2.7%). The largest group (23.8%) graduated after 2010. More than 90% indicated that they followed American Dental Association (ADA)-AAPD radiation exposure guidelines, but only 33.5% were aware of IGCD. Almost all respondents used direct digital systems, storage phosphor plates, or both. Only 22.3% (n = 220) used rectangular collimation. Nonusers indicated that they were unfamiliar with collimation (33.3%) or concerned about potential for increased cone cuts (30.2%), 11.6% of respondents were unaware of any regulatory requirements for inspections of radiographic equipment recurring at regular intervals, and 4.1% of respondents considered use of lead aprons optional.ConclusionsAlthough the pediatric dentists surveyed believe they are in compliance with ADA-AAPD guidelines, most are unaware of IGCD recommendations. Use of digital radiography is almost ubiquitous, but use of rectangular collimation is limited.Practice ImplicationsDentists treating children should be familiar with ADA-AAPD radiation exposure guidelines and should consider using the dose-reduction strategies recommended by IGCD.     

Dysgeusia: A review in the context of COVID-19

BackgroundTaste disorders in general, and dysgeusia in particular, are relatively common disorders that may be a sign of a more complex acute or chronic medical condition. During the COVID-19 pandemic, taste disorders have found their way into the realm of general as well as specialty dentistry, with significance in screening for patients who potentially may have the virus.Types of Studies ReviewedThe authors searched electronic databases (PubMed, Embase, Web of Science, Google Scholar) for studies focused on dysgeusia, ageusia, and other taste disorders and their relationship to local and systemic causes.ResultsThe authors found pertinent literature explaining the normal physiology of taste sensation, proposals for suggested new tastes, presence of gustatory receptors in remote tissues of the body, and etiology and pathophysiology of taste disorders, in addition to the valuable knowledge gained about gustatory disorders in the context of COVID-19. Along with olfactory disorders, taste disorders are one of the earliest suggestive symptoms of COVID-19 infection.ConclusionsGustatory disorders are the result of local or systemic etiology or both. Newer taste sensations, such as calcium and fat tastes, have been discovered, as well as taste receptors that are remote from the oropharyngeal area. Literature published during the COVID-19 pandemic to date reinforces the significance of early detection of potential patients with COVID-19 by means of screening for recent-onset taste disorders.Practical ImplicationsTimely screening and identification of potential gustatory disorders are paramount for the dental care practitioner to aid in the early diagnosis of COVID-19 and other serious systemic disorders.     

Willingness and ability of oral health care workers to work during the COVID-19 pandemic

BackgroundThe COVID-19 pandemic continues to disrupt dental practice in the United States. Oral health care workers play an integral role in societal health, yet little is known about their willingness and ability to work during a pandemic.MethodsOral health care workers completed a survey distributed on dental-specific Facebook groups during an 8-week period (May 1-June 30, 2020) about their willingness and ability to work during the COVID-19 pandemic, barriers to working, and willingness to receive a COVID-19 vaccine.ResultsFour hundred and fifty-nine surveys were returned. Only 53% of dentists, 33% of dental hygienists, 29% of dental assistants, and 48% of nonclinical staff members would be able to work a normal shift during the pandemic, and even fewer (50%, 18%, 17%, and 38%, respectively) would be willing to work a normal shift. Barriers included caring for family, a second job, and personal obligations, and these were faced by dental assistants and hygienists. Dentists were more likely than hygienists (P < .001), assistants (P < .001), and nonclinical staff members (P = .014) to receive a COVID-19 vaccine.ConclusionsOral health care workers have a decreased ability and willingness to report to work during a pandemic, and dentists are significantly more able and willing to work than hygienists and assistants. Dentists are more likely than staff to receive a COVID-19 vaccine.Practical ImplicationsThe results of this study may help inform future initiatives of dental workforce readiness during a pandemic. Dentists should be prepared to discuss alterations to standard operating procedures to allay staff members’ fears and improve retention rates during pandemics, allowing for improved access to oral health care.     

The impact of COVID-19 lockdown on maintenance of children's dental health: A questionnaire-based survey

BackgroundThe COVID-19 pandemic has been associated with several changes in maintenance of children's dental health. The aim of this study was to evaluate the extent of these changes.MethodsParents were asked to respond anonymously to a questionnaire regarding alterations in their children's oral habits, such as frequency of eating and drinking, toothbrushing, signs of stress, and receiving oral health care during the lockdown period. The participants were reached either during their visit to the clinics or via the social media groups of the authors.ResultsThere were 308 parents of children aged 1 through 18 years who responded to the questionnaires. The authors found associations between increased frequency of eating and drinking, decreased frequency of toothbrushing, and postponing oral health care. Among the children, 11% experienced more frequent oral signs of stress, such as temporomandibular disorder and aphthous stomatitis, during the lockdown. Although children from all age groups ate and drank more frequently between meals, younger children received a diagnosis of carious lesions more often during the lockdown (P = .015).ConclusionsDuring the lockdown, many children changed their eating, drinking, and toothbrushing habits and, thus, increased their risk of developing caries.Practical ImplicationsDuring pandemic-associated re-care visits or recall visits, it is imperative to conduct a detailed interview regarding changes in oral health habits. In children at high risk, dentists recommended more diagnostic and preventive measures to prevent deterioration of their oral health. Moreover, dentists should put more emphasis on motivational interviewing to help children resume healthier routines after the lockdown.     

A simple screening tool for occupational burnout among dentists

BackgroundNearly 40% of US physicians experience occupational burnout. The actual prevalence rate of burnout among US dentists remains unknown. The authors examined a simplified 2-item burnout screening tool based on the Maslach Burnout Inventory (MBI) to identify possible occupational burnout among dentists.MethodsData were obtained from a survey of pediatric dentists (n = 540) in the United States. The full MBI items from the data set were used to determine and categorize emotional exhaustion and depersonalization. Responses to 2 MBI items, 1 for emotional exhaustion and 1 for depersonalization, were analyzed separately and risk of experiencing high MBI emotional exhaustion and depersonalization was calculated using all subscale items for these 2 burnout dimensions. Spearman correlations were used to compare responses to the 2 MBI items and MBI emotional exhaustion and depersonalization.ResultsBased on frequency of at least once per week, 18% of respondents had positive response to MBI item “I feel burned out from my work” and had high MBI emotional exhaustion, and 9% had positive response to MBI item “I have become more callous toward people since I took this job” along with high MBI depersonalization. The risk of experiencing the burnout dimensions of high emotional exhaustion and depersonalization increased with positive frequency score for the respective MBI items. There were strong positive correlations between responses to the 2 MBI items and emotional exhaustion and depersonalization scores, respectively.ConclusionsA simple 2-item burnout screening tool can be used to identify potential occupational burnout among dentists.Practical ImplicationsImproving awareness about occupational burnout can help mitigate its detrimental consequences.     

Caregiver acceptance of an anticipated COVID-19 vaccination

BackgroundThe world is hopeful a vaccine will help mitigate the COVID-19 pandemic. The authors conducted a hospital-based study using a questionnaire to examine parental acceptance of an anticipated COVID-19 vaccination.MethodsA 41-item questionnaire using the Health Belief Model was administered to caregivers of children receiving oral health care in a dental clinic in an urban pediatric teaching hospital. Demographic, health-seeking, and health-behavior questions were assessed.ResultsA total of 39.2% of caregivers would not allow their child to receive a COVID-19 vaccination. Whereas 27.8% of caregivers agreed that if their physician recommends a COVID-19 vaccination, they will allow their child to receive it, 52.2% said that a health care professional could influence this decision.ConclusionsDentists, intimately aware of the suggested risks of aerosol-generating procedures, can play a critical role in educating the public about the importance of accepting a COVID-19 vaccine.Practical ImplicationsDentists are in a unique position to discuss and advocate for vaccine acceptance. If a COVID-19 vaccine is not widely accepted, risks associated with performing aerosol-generating procedures will remain.     

US dental health care workers’ mental health during the COVID-19 pandemic

BackgroundThis study was designed to assess the prevalence of anxiety and depression symptoms and understand factors influencing mental health among dental health care workers (DHCWs) during the COVID-19 pandemic.MethodsBeginning in June 2020, 8,902 DHCWs participated monthly in an anonymous longitudinal, web-based survey (response rate, 6.7%). The Patient Health Questionnaire-4 was used to estimate rates of anxiety and depression symptoms. Changes in mental health over time and differences by demographic and practice characteristics, COVID-19 community transmission level, and COVID-19 vaccination status were tested using χ² tests and multilevel multivariable logistic regression.ResultsAnxiety symptom rates peaked in November 2020 (28% of dental hygienists, 17% of dentists) and declined to 12% for both professions in May 2021. Depression symptom rates were highest in December 2020 (17% of dental hygienists, 10% of dentists) and declined to 8% in May 2021. Controlling for gender, age, race or ethnicity, and COVID-19 community transmission level, the authors found that dentists had significantly lower odds of anxiety symptoms (adjusted odds ratio [aOR], 0.82; 95% CI, 0.70 to 0.95) and depression symptoms (aOR, 0.79; 95% CI, 0.67 to 0.93) than dental hygienists. Compared with vaccinated respondents, those who were unvaccinated but planning on getting vaccinated had significantly higher rates of anxiety (aOR, 1.71; 95% CI, 1.20 to 2.44) and depression (aOR, 1.57; 95% CI, 1.07 to 2.29) symptoms.ConclusionsDHCWs’ mental health fluctuated during the pandemic. Anxiety and depression in DHCWs were associated with demographic and professional characteristics as well as perceived risk of COVID-19.Practical ImplicationsMental health support should be made available for DHCWs.This clinical trial was registered at ClinicalTrials.gov. The registration numbers are NCT04423770 and NCT04542915.     

Dental health status,use, and insurance coverage among adults with chronic conditions: Implications for medical-dental integration in the United States

BackgroundThe authors examined potential benefits and difficulties in integrating oral health care and medical care for adults with chronic conditions (CCs).MethodsThe authors used National Health and Nutrition Examination Survey 2009-2016 data to estimate crude (age- and sex-standardized) and model-adjusted estimates to examine the association between dental disease (severe tooth loss, untreated caries) and chronic disease (≥ 3 CCs, fair or poor health) and Medical Expenditure Panel Survey 2014-2016 data to estimate crude estimates of past-year medical and dental use and financial access according to CC status. Reported differences are significant at P < .05.ResultsNational prevalences of reporting fair or poor health and 3 or more CCs were both approximately 15%. Standardized prevalence of dental disease was notably higher among adults reporting CCs than those not reporting. After controlling for covariates, the magnitude of the association was substantially lower, although the association remained significant. Adults with CCs were approximately 50% more likely to report having a past-year medical visit and no dental visit than those not reporting CCs. Among adults reporting CCs, prevalence of having no private dental insurance and low income was approximately 20% and 60% higher, respectively, than that among adults not reporting CCs.ConclusionsAdults with CCs had higher prevalence of dental disease, past-year medical visit and no dental visit, and limited financial access.Practical ImplicationsMedical visits may be the only opportunity to provide dental education and referrals to adults with CCs. Improved medical-dental integration could improve oral health care access and oral health among these adults who are at higher risk of dental disease.     

Trends in use of dental care provider types and services in the United States in 2000-2016: Rural-urban comparisons

BackgroundThe authors conducted a study to assess recent trends in dental care provider mix (type of dental professionals visited) and service mix (types of dental procedures) use in the United States and to assess rural-urban disparities.MethodsData were from the 2000 through 2016 Medical Expenditure Panel Survey. The sample was limited to respondents who reported at least 1 dental visit to a dental professional in the survey year (N = 138,734 adults ≥ 18 years). The authors estimated rates of visiting 3 dental professionals and undergoing 5 dental procedures and assessed the time trends by rural-urban residence and variation within rural areas. Multiple logistic regression was used to assess the association between rural and urban residence and service and provider mix.ResultsA decreasing trend was observed in visiting a general dentist, and an increasing trend was observed in visiting a dental hygienist for both urban and rural residents (trend P values < .001). An increasing trend in having preventive procedures and a decreasing trend in having restorative and oral surgery procedures were observed only for urban residents (trend P values < .001). The combined data for 2000 through 2016 showed that rural residents were less likely to receive diagnostic services (adjusted odds ratio [AOR], 0.82; 95% confidence interval [CI], 0.72 to 0.93) and preventive services (AOR, 0.87; 95% CI, 0.78 to 0.96), and more likely to receive restorative (AOR, 1.11; 95% CI, 1.02 to 1.21) and oral surgery services (AOR, 1.23; 95% CI, 1.11 to 1.37).ConclusionsAlthough preventive dental services increased while surgical procedures decreased from 2000 through 2016 in the United States, significant oral health care disparities were found between rural and urban residents.Practical ImplicationsThese results of this study may help inform future initiatives to improve oral health in underserved communities. By understanding the types of providers visited and dental services received, US dentists will be better positioned to meet their patients’ oral health needs.     

Testing for COVID-19 in dental offices: Mechanism of action,application, and interpretation of laboratory and point-of-care screening tests

BackgroundThe dental office potentially possesses all transmission risk factors for severe acute respiratory syndrome coronavirus 2. Anticipating the future widespread use of COVID-19 testing in dental offices, the authors wrote this article as a proactive effort to provide dental health care providers with current and necessary information surrounding the topic.MethodsThe authors consulted all relevant and current guidelines from the Centers for Disease Control and Prevention and the US Food and Drug Administration, as well as online resources and review articles.ResultsRoutine COVID-19 screening and triage protocols are unable to detect all infected people. With the advancements in diagnostic tools and techniques, COVID-19 testing at home or in the dental office may provide dentists with the ability to evaluate the disease status of their patients. At-home or point-of-care (POC) tests, providing results within minutes of being administered, would allow for appropriate measures and rapid decisions about dental patients' care process. In this review, the authors provide information about available laboratory and POC COVID-19 screening methods and identify and elaborate on the options available for use by dentists as well as the regulatory requirements of test administration.ConclusionsDentists need to be familiar with COVID-19 POC testing options. In addition to contributing to public health, such tests may deliver rapid, accurate, and actionable results to clinical and infection control teams to enhance the safe patient flow in dental practices.Practical ImplicationsOral health care must continue to offer safety in this or any future pandemics. Testing for severe acute respiratory syndrome coronavirus 2 at the POC offers a control mechanism contributing to and enhancing the real and perceived safety of care in the dental office setting.     

The prevalence of comorbid chronic pain conditions among patients with temporomandibular disorders: A systematic review

BackgroundThis systematic review was designed to evaluate the presence of comorbid conditions among patients with temporomandibular disorders (TMDs).Types of Studies ReviewedThe authors reviewed studies that reported the prevalence or incidence of chronic pain conditions or psychiatric disorders (anxiety, mood, personality disorders) among patients with any type of TMD. The authors calculated sample size–weighted prevalence estimates when data were reported in 2 or more studies for the same comorbid condition.ResultsA total of 9 prevalence studies and no incidence studies were eligible for review; 8 of the studies examined chronic pain comorbidities. Weighted estimates showed high prevalence of pain comorbidities across studies, including current chronic back pain (66%), myofascial syndrome (50%), chronic stomach pain (50%), chronic migraine headache (40%), irritable bowel syndrome (19%), and fibromyalgia (14%). A single study examined psychiatric disorders and found that current depression was the most prevalent disorder identified (17.5%).Conclusions and Practical ImplicationsThere is a high prevalence of comorbid chronic pain conditions among patients with TMDs, with more than 50% of patients reporting chronic back pain, myofascial syndrome, and chronic stomach pain. Psychiatric disorders among patients with different types of TMDs were studied less commonly in this pain population. Knowledge of the distribution of these and other comorbid disease conditions among patients with different types of TMDs can help dentists and other health care providers to identify personalized treatment strategies, including the coordination of care across medical specialties.
