Knowledge, attitudes, and psychosocial impacts among Brazilian Pediatric Dentists during COVID-19 pandemic

Abstract:

In this study, we evaluated the knowledge, attitudes, and psychosocial impacts among Brazilian pediatric dentists during the COVID-19 pandemic. A cross-sectional study with primary data collection was carried out using an online structured questionnaire. Data were submitted to descriptive analysis by using absolute and relative frequencies. A chi-square test was used for association analysis and log-linear regression models to estimate the prevalence ratio (5%). The population comprised mostly women and knowledge regarding COVID-19 was satisfactory (above 80% in most items). N95 masks and faceshields were used, albeit 64.22% reported difficulty in providing dental care to children due to the need for extra Personal Protective Equipment. Thirty eight percent provided urgency/emergency dental care, 59.78% performed invasive procedures, 59.56% used high speed handpieces, 8.44% started using cariostatics, and 6.22% introduced the use of chemomechanical caries removal agents. Fear for the future (PR = 1.21) and use of medications (for anxiety, depression, or insomnia) increased (PR = 1.16) among the ones who had wage losses. Brazilian pediatric dentists have knowledge about COVID-19, and attitudes in their clinical routines changed due the pandemic. Financial life was harmed and a negative impact of the pandemic in psychosocial aspects of workers was found.

Introduction

In March 2020, the World Health Organization declared a pandemic due to COVID-19. The Coronavirus Disease-2019, caused by the coronavirus (SARS-CoV-2), has been spreading exponentially, causing thousands of deaths worldwide.¹ SARS-CoV-2 can be transmitted directly and indirectly. Aerosols and droplets are considered the main means of spreading and dissemination of the disease.² These findings reinforce the need for effective preventive measures for biosafety in dental offices.

In addition to the constant vigilance needed in implementing COVID-19 control measures, the pandemic has had a series of psychosocial implications, affected individuals of different social classes.³ During a pandemic, fear increases anxiety and stress levels in healthy individuals and intensifies the symptoms of pre-existing psychiatric disorders.⁴ Mental health tends to be impacted in individuals affected by the infection.⁵ Uncertainties stemming from the pandemic have consequences in several sectors, with direct implications in everyday life and mental health.

Healthcare workers have been at the forefront of the COVID-19 response and are considered the most psychologically affected group; they face an increased workload, fear of contaminating themselves and family members, misinformation, and anger due to a lack of professional support.³ Dentists must adapt to this new situation. The use of personal protective equipment (PPE), while a part of standard practice, has increased fear and anxiety in dental offices. Pediatric dentists work with children, who are considered potential vectors of the disease, as they may be asymptomatic, present mild symptoms, carry the virus, and spreading the infection.⁶

Recently, a cross-sectional online survey assessed dentists from different specialties for their knowledge and perceptions of COVID-19, and among them, oral maxillofacial surgeons showed higher knowledge scores.⁷ In the state of São Paulo, Brazil, a cross-sectional study evaluated the impact of the pandemic among dentists, and 83% reported not having any specific training to control the transmission of coronavirus.⁸ This research aimed to understand the attitudes adopted by pediatric dentists, and to identify psychosocial aspects related to the COVID-19 pandemic.

Methodology

Ethical considerations

This project was approved by the Research Ethics Committee of the Ribeirão Preto School of Dentistry / University of São Paulo (CAAE 33334620.2.0000.5419).

Study design

A cross-sectional study with primary data collection through a structured questionnaire.

Formulation of questionnaires

A Google Forms (Google Inc., Mountain View, USA) questionnaire was developed and sent by e-mail and WhatsApp (WhatsAPP Inc., Mountain View, USA) to Brazilian pediatric dentists weekly, from July 3 to August 4, 2020, consolidating convenience sampling. The survey was divided into Section A (demographic information and professional characteristics); Section B (symptoms, mode of transmission, control measures, and patients with COVID-19 treating attitude), and Section C (psychosocial aspects).

Statistical analysis

The information collected was pre-processed to validate the responses and eliminate errors and duplications in electronic spreadsheets. We performed a descriptive analysis using absolute (n) and relative (percentage) frequencies. A chi-square association test and log-linear regression models were used to estimate the prevalence ratio to verify the association of income loss with psychosocial aspects.⁷ In all analyses, we used a significance level of 5%.

Results

Of the 508 Brazilian pediatric dentists surveyed, 58 were duplicated, so the sample comprised 450 questionnaires. Most were female (95.5%) aged between 31 and 50 years (56%). The number of professionals who graduated from public and private schools did not vary, and the highest average time since graduation ranged from 21 to 25 years (18.2%), with a specialist's degree (62.4%), master's degree (18.89%), and doctorate degree (18.67%) in pediatric dentistry. Most professionals worked in private practice, with a workload between 31 and 40 hours per week (37.6%) (Table 1).

The majority performed handwashing before and after patient care (99.56%) and utilized alcohol-based hand sanitizer for disinfection (98.89%). The N95 mask was used by 78.67% of the professionals, while 54.22% merely used the surgical mask, and 43.33% adhered to the overlay of the two masks. The faceshield was used by 83.11% of pediatric dentists, and 64.22% reported difficulties in working with children due to the implementation of these extra PPE.

Pediatric dentists reported cases involving only urgencies and emergencies (38%), and 59.78% performed invasive procedures. Concerning the use of handpieces, 59.56% used high-speed and 71.33% used low-speed handpieces. Regarding cariostatics, 33.56% stated that they used the product before, 8.44% started using it during the pandemic, while 46% did not use it. With respect to chemomechanical caries removal, 35.56% integrated this procedure into clinical practice, 6.22% introduced the treatment during the pandemic period, and 44% did not use it.

A high percentage (74.22%) of respondents stated that they had postponed all patients’ treatments during this period. Most dentists (92.22%) reported that they did not take care or did not know if any patient who was undergoing dental treatment tested positive for COVID-19 and 7.78% treated a patient with COVID-19.

Among the respondents, 59.11% felt unsafe about performing dental care during the pandemic period, 50.67% reported fear, 83.78% felt more stress during this period, 49.56% experienced insomnia, and 17.5% sought help to overcome emotional symptoms.

Discussion

This study provides a panoramic view of the COVID-19 pandemic among Brazilian pediatric dentists. A survey utilizing the Google Forms questionnaire was sent by the Internet, which allowed for a wide coverage. This survey was consistent with that of previous studies, and it allowed a wide coverage, due to the ease of access.⁹–¹¹ Most respondents (95.56%) were women, which reflects the predominance of female pediatric dentists in Brazil. In 2020, a study showed that among pediatric dentists in England, the proportion of women was almost three times that of men.¹² In the United States of America, research showed that between 2010 and 2016, the largest growth among female dentists was in pediatric dentistry (44.3%).¹³ Most pediatric dentists are in the age range of 31 to 50 years, have held their degree for more than 20 years, and possess a Specialist's degree (62.4%) in pediatric dentistry.

The surveyed professionals were aware of the disease incubation period, transmission methods, and symptoms of COVID-19. Nonetheless, the clinical manifestations of COVID-19 in children are not as clear as in adults. Bi et al. (2020)¹⁴ conducted an assessment in China with over 2000 children with suspected or diagnosed COVID-19, and found that over 90% were asymptomatic or had only moderate symptoms. Another study, which analyzed 2,143 infected Chinese children, indicated that 4% were asymptomatic, 51% had mild symptoms, 39% were moderate, and 6% were in a critical state. The proportion of severe cases varied according to the age group, with 11% in children under 1 year old, 7% between 1 and 5 years, 4% from 6 to 10 years, 4% in children aged 11 to 15 years, and 3% in children aged 16 to 19 years old.¹⁵ Other researchers have inferred that infected children may be asymptomatic or have abdominal discomfort, nausea, vomiting, abdominal pain, and diarrhea. Nevertheless, they reinforce that these children have mild clinical manifestations, usually have a good prognosis, and recover within 1 and 2 weeks.¹⁶,¹⁷ Recently, a systematic review of COVID-19 in pediatric patients concluded that this virus also affects children and causes systemic disease involving several internal organs; in addition, the prevalence, severity, and diversity of the symptoms are lower than in adults. The most common symptoms are cough and fever, followed by gastrointestinal manifestations, and the risk of severe COVID-19 is greater in children with comorbidities. In addition, this research highlighted increased rates of anxiety and depression due to the isolated situation.¹⁸ Therefore, this disease profile in children puts them at higher risk of potential COVID-19 transmission. Pediatric dentists must be aware of all possible manifestations of the disease to take stringent transmission control measures in the clinical environment.

Biosafety in dental offices has always been a concern among dentists. The physical proximity between patients and professionals, the aerosol generated instruments, such as high-speed handpieces and Cavitron cleaners, and contact with saliva and blood, expose dental professionals to potential contamination. In this study, we found that infection control measures such as handwashing and disinfecting with alcohol-based sanitizer were common among pediatric dentists (99.6% and 98.89%, respectively). Almost 80% wore N95 masks and 83.11% wore faceshields, and many even reported difficulty in practicing on children due to the extra PPE. These findings are supported by Consolo et al.,¹⁹ who reported that 77% of dentists increased the PPE use due to the COVID-19 pandemic. The increasing demand for PPE inflated the price of these products, contributing to the financial crisis; 34.44% of respondents stated that there was over a 50% reduction in earnings and 33.78% reported losses between 20 to 50%. Moreover, over 70% reported postponing dental treatment. These data agree with a recent Brazilian National online survey led by Morais et al. (2020),²⁰ which showed that the number of patients receiving dental treatment significantly decreased, with most receiving urgent and emergency care.

Since March 20, 2020, the National Health Surveillance Agency (ANVISA) in Brazil has recommended that only emergency and dental care be performed, and the Federal Council of Dentistry advised the use of non-invasive procedures.²¹ Therefore, procedures that do not generate aerosols, such as atraumatic restorations, cariostatic restorations, and chemomechanical caries removal, have been recommended.²²–²⁴ In the present study, Brazilian pediatric dentists used more low-speed handpieces (71.33%) than high-speed (59.56%). A small number of dentists adhered to the guideline of cariostatic (8.44%) and chemomechanical agent use (6.22%).

Regarding the psychological implications, uncertainty in dental practice, fear, and stress were evident, along with insomnia, which appeared in almost 50% of professionals. Many reported taking some medication to control such symptoms, such as herbal medicine, homeopathic and anxiolytics, or antidepressants. Our data support other studies that found high anxiety levels, stress symptoms, and other emotional disorders among distinct healthcare workers. In China, the originating location of the outbreak, anxiety, depression, and stress have been identified among healthcare workers.²⁵ Lai et al.²⁶ found a higher occurrence of both insomnia and distress.

In an online cross-sectional survey on the impact of COVID-19 pandemic among physicians, nurses, and dentists in Brazil, aside from experiencing the most job loss, dentists presented more anxiety and stress symptoms and difficulty sleeping.²⁷ Petzold et al. (2020)³ inferred that social support, communication, distribution of tasks, flexible working hours, and psychological aid must be implemented to decrease emotional stress. Our data reveal that a large percentage of pediatric dentists feel distraught by the government and representative councils and fear the future, and it is up to the representative councils to develop and provide care and support strategies. Our results corroborate with the literature, when assessing the association between psychosocial aspects related to lost wages (between 20-50% and higher than 50%) among pediatric dentists. We found that fear of the future and the use of medication for anxiety, depression, and insomnia was higher among those who suffered wage losses.

It is evident that the COVID-19 pandemic has influenced Brazilian pediatric dentists. It should also be stressed that pediatric dentistry has some peculiarities, including close professional contact with children, behavioral management techniques such as protective stabilization, the use of cheek retractors, and the use of playful objects, such as dolls and toys, all of which facilitate care for non-cooperative children. The impracticality of performing behavior management techniques with extra PPE, such as the faceshield or N95 mask, presents an additional challenge to the practice of pediatric dentistry. Another anomaly in pediatric dentistry is the need for an adult present, who is responsible for the child during the appointments. However, this increases the number of people involved in clinical care, further exposing them to possible SARS-CoV-2 contamination. Currently, people are better adapted to the conditions and regulations imposed by the pandemic. Elective care in private dental offices and public clinics is gradually being reinstated, and it is likely that professionals and patients have adapted to all the new measures. Thus, questionnaires, as in the present study, should be applied to monitor the ongoing status of pediatric dentistry in Brazil.

Despite the limitations in data collection, due to conflicting schedules or difficulty with electronic forms, we identifed an urgent need to improve the pediatric clinic routine. Dental care cannot be neglected, even during a pandemic. Children's dental care is fundamental, as orofacial pain has a negative impact on children's quality of life.²⁷ Chisini et al.²⁸ conducted a study in the public national systems in Brazil, and showed a 89% decrease in children's dental practice in April 2020, a peak of the pandemic. Witton et al.²⁹ conducted a qualitative research study in England to identify dental reforms post-pandemic, and reported that children's oral health was harmed due to the suspension of elective treatments. Therefore, the researchers recommended the creation of child oral health programs post-pandemic. Kochhar et al.³⁰ stressed that children should feel comfortable with the extra PPE in order to reduce fear and increase cooperation. Pediatric dentists must stay up to date on COVID-19 prevention measures, conduct training, and follow biosafety protocols to minimize the negative effect that the pandemic may have on children's dental health.

Conclusion

This study showed that Brazilian pediatric dentists are knowledge about COVID-19 symptoms, and the attitudes in their clinical routines have changed due to the pandemic. There was a decrease in the number of patients, and the changes in PPE made the practice of pediatric dentistry more difficult. Regarding psychosocial aspects, lack of safety, fear, stress, and insomnia were reported by most pediatric dentists, and medications such as herbal medicines, homeopathic and anxiolytics, or antidepressants, have been used to overcome emotional distress. The financial lives of these professionals were harmed, and fear of the future and the use of medication for anxiety, depression, and insomnia were more common among those who had wage losses between 20-50% and higher than 50%. More support strategies must be provided by the government and representative councils to minimize the economic and emotional impacts of the COVID-19 pandemic on Brazilian pediatric dentists.
