LGBTQIA+ vs the Brazilian Unified Health System: Basic Health Unit Use and Associated Factors

The Brazilian Unified Health System provides universal health care access without regard to sexual orientation and gender identity. We conducted a nationwide study with a cross-sectional design and intentional sampling methods to investigate factors associated with Basic Health Unit (BHU) use by the LGBTQIA+ community. Data were collected via a questionnaire available through social networks. Statistical analysis included Poisson regression with robust variance. A total of 603 LGBTQIA+ community members participated in the study, of whom 417 (69.2%) had visited a BHU in the last year. The factors "transgender woman" and "self-rated health status as very good/good/fair" increased the probability of BHU use in the last year by 10% (PR: 1.10; 95% CI: 1.00-1.20) and 9% (PR = 1.09; 95% CI: 1.01-1.18), respectively. "Not suffering sexual orientation-related discrimination at a BHU" and "Not suffering discrimination by a receptionist or waiting room worker" increased the probability of use by 28% (PR = 1.28; 95% CI: 1.22-1.34) and 22% (PR = 1.22; 95% CI: 1.14-1.30), respectively. Our study supports evidence that access to primary health care services in Brazil can be influenced by the social determinants gender identity and sexual discrimination.

Factors related to occupational stress among private sector dentists in the first year of the COVID-19 pandemic

This cross-sectional study examined factors associated with occupational stress among 384 dentists working in the private sector in the first year of the COVID-19 pandemic in Brazil. Data were collected from August to October 2020 through an online form. Two outcomes - (1) anxiety and worry and (2) preparation and safety for work during the pandemic - constituted a proxy for occupational stress. The independent variables were grouped according to the explanatory theoretical model into individual, organisational and extra-organisational factors. Associations were tested by bivariate and multivariate logistic regression. Although prepared and confident, dentists felt anxious and worried about providing clinical care. Women, younger respondents and those who received no guidance on safety measures were more likely to report insecurity and unpreparedness. Younger professionals, those who did not participate in decision-making and who only sometimes had an assistant for four-hand work, were more likely to feel anxious and worried. In addition to individual factors, work organisation factors were associated with occupational stress among dentists in the first year of the pandemic.

Online videos: The hidden curriculum

INTRODUCTION

Dental undergraduates will access the Internet searching for learning materials to complement their training; however, open access content is not generally recommended by dental schools. This study aimed to evaluate how dental students are using online video content.

MATERIALS AND METHODS

Students from eight Universities (Athens, Birmingham, Brescia, Cardiff, Melbourne, Paris, Sao Paulo and Valdivia) representing three continents were invited to complete a survey on their access and learning from online videos.

RESULTS

International students behave similarly when studying dental content online. Of 515 respondents, 94.6% use the Internet as a learning tool. It was observed that videos are not frequently recommended during didactic lectures (9.6%). But many students (79.9%) will use YouTube for their learning which includes clinical procedures. Students will check online content before performing procedures for the first time (74.8%), to understand what was explained in class (65.9%) or read in books (59.5%), to relearn clinical techniques (64.7%) and to visualise rare procedures (49.8%). More than half of the students do not fully trust the accuracy or the reliability of online content. This does not prevent students from watching and sharing dental videos with classmates (64.4%). The content watched is not shared with teachers (23.3%) even when it contradicts what was learnt in the school (38.2%).

CONCLUSION

This study concludes that students regularly integrate open access digital resources into learning portfolios but are hesitant to inform their teachers about their viewing habits. Students wish to receive critical skills on how to evaluate the material they encounter outside their traditional learning space.

COVID-19 incidence, severity, medication use, and vaccination among dentists: survey during the second wave in Brazil

Objective

This cross-sectional study with dentists in Brazil assessed the COVID-19 incidence and severity, its vaccination status, and the level of confidence in vaccines in May 2021 (COVID-19 second wave). The medications used to prevent or treat COVID-19, including controversial substances (vitamin D, ivermectin, zinc, and chloroquine), were analyzed.

Methodology

Dentists were recruited by email and responded to a pretested questionnaire until May 31, 2021. Bivariate and multivariate regression analyses were performed (α=0.05). Prevalence ratios were calculated for the association between professional characteristics and two outcomes: SARS-CoV-2 infection and use of controversial substances.

Results

In total, 1,907 responses were received (return rate of 21.2%). One third of dentists reported intermediate levels of confidence in the safety and efficacy of COVID-19 vaccines, but 96% had received at least one vaccine dose, mainly CoronaVac. The effect of the pandemic on dental practice was classified as lower/much lower, in comparison with the first wave, by 46% of participants. Moreover, 27% of dentists had already tested positive for SARS-CoV-2 and about 50% had relatives or friends who had been hospitalized or died from COVID-19. At least one medication was used by 59% of participants and 43% used two or more substances. Vitamin D (41%), ivermectin (35%), and zinc (29%) were the most frequent substances. More experienced dentists (≥21 years of professional experience) were 42% more likely to use controversial substances than less experienced dentists. The prevalence of use of controversial substances was 30% higher among dentists with residency or advanced training, such as postgraduate degrees, in comparison with participants holding MSc or PhD degrees. Participants with low confidence in vaccines were 2.1 times more likely to use controversial substances than participants with a very high confidence.

Conclusion

The results of this study show the high severity of the COVID-19 pandemic in Brazil and raised questions about the use of scientific evidence by dentists in their decision to use controversial substances.

How is working length determination taught? A survey to assess what is recommended in undergraduate Schools of Dentistry in Brazil

INTRODUCTION

To analyse what are the methods for working length (WLD) determination taught for undergraduate students in Brazilian Dental Schools and the perception of professors about the use of electronic WL determination in the clinical practice.

METHODS

An online questionnaire with eighteen closed questions was sent to 209 Schools of Dentistry in Brazil using the Google Forms Platform. The questionnaire was structured to analyse the perception of professors in the department of endodontics about the method of working length determination taught in undergraduate courses in Dentistry. The data collected in the questionnaires were transferred to an Excel^® spreadsheet and analysed using absolute and relative frequencies. The non-parametric Mann-Whitney test was used to compare groups.

RESULTS

Of the 209 schools contacted, 41 (19.61%) returned answers to the questionnaire. According to professors, electronic working length (WL) determination had a shorter length of time to perform it (p < .001), WL measurement accuracy (p < .001) and ease of performance (p < .001). Professors felt safer when maintaining patency when using electronic WL determination (p = .0020).

CONCLUSIONS

Both radiographic and electronic methods of WL determination are taught in Brazilian Schools of Dentistry. The electronic method was used more frequently, especially in undergraduate clinical courses.

A multi-country survey on the impact of COVID-19 on dental practice and dentists' feelings in Latin America

BACKGROUND

The COVID-19 pandemic has significantly influenced the routine of healthcare workers. This study investigated the impact of the pandemic on dental practice and dentists' feelings in Latin America.

METHODS

A survey was conducted with dentists from 11 Spanish-speaking Latin American countries in September-December 2020. Professionals were invited by email and via an open campaign promoted on social media. The questions investigated dental care routines, practice changes, and feelings about the pandemic. Descriptive statistics were used to identify frequencies and distributions of variables. Proportions were compared using chi-square tests.

RESULTS

A total of 2127 responses were collected from a sample with diverse demographic, sex, work, and education characteristics. The impact of COVID-19 was considered high/very high by 60% of respondents. The volume of patients assisted weekly was lower compared with the pre-pandemic period (mean reduction = 14 ± 15 patients). A high rate of fear to contracting the COVID-19 at work was observed (85%); 4.9% of participants had a positive COVID-19 test. The main professional challenges faced by respondents were reduction in the number of patients or financial gain (35%), fear of contracting COVID-19 (34%), and burden with or difficulty in purchasing new personal protective equipment (22%). The fear to contracting COVID-19 was influenced by the number of weekly appointments. A positive test by the dentists was associated with their reports of having assisted COVID-19 patients. The most cited feelings about the pandemic were uncertainty, fear, worry, anxiety, and stress. Negative feelings were more prevalent for professionals who did not receive training for COVID-19 preventive measures and those reporting higher levels of fear to contract the disease.

CONCLUSION

This multi-country survey indicated a high impact of the pandemic on dental care routines in Latin America. A massive prevalence of bad feelings was associated with the pandemic.

Knowledge About Biosafety Measures in Clinical Setting During the COVID-19 Pandemic: A Cross-Sectional Study With Brazilian Dental Students

OBJECTIVE

The aim of this study is to evaluate the knowledge of Brazilian dental students about biosafety measures that should be adopted in the clinical setting during the coronavirus disease (COVID-19) pandemic.

METHODS

A cross-sectional study with 1050 dental students was conducted. A semi-structured questionnaire was shared with students. Mean knowledge score on biosafety guidelines during the COVID-19 pandemic was the outcome, with a maximum of 8 scores. Explanatory variables included sociodemographic and educational characteristics, aspects related to biosafety education, actions adopted by the dental schools during the pandemic, and sources of biosafety information. Multivariate linear regression analyses were performed.

RESULTS

Mean knowledge score was 5.19 (1.28). Female students (β = 0.346; 95% CI: 0.154-0.539), those enrolled in the intermediate (β = 0.525; 95% CI: 0.167-0.883) or final (β = 0.569; 95% CI: 0.200-0.937) stage of course, and those who had already received theoretical-practical training in biosafety (β = 0.464; 95% CI: 0.063-0.866) presented higher mean knowledge scores. Students who did not receive guidance on aerosol control measures before the pandemic (β = -0.324; 95% CI: -0.519 to -0.130) had the lowest score.

CONCLUSION

Students presented a medium level of knowledge about dental biosafety measures concerning the COVID-19 pandemic. Sociodemographic characteristics and those related to the institutional profile of the participants, and access to orientation and training in biosafety, may influence their knowledge.

Charcoal-based dentifrices and powders: analyses of product labels, Instagram engagement, and altmetrics

This study identified charcoal-based dentifrices and abrasive powders sold in Brazil and analyzed their label information. The products were searched in four online shopping platforms. The same products were searched on Instagram and their engagement metrics were investigated. Furthermore, a literature review of international publications assessing charcoal dentifrices and powders was conducted, and altmetrics were collected (Altmetric and PlumX). Thirty-six products were found with prices between $0.4-22 USD. Most frequent words in product description were sodium, stain, whitening, oil, xylitol, and coconut. Only 3 products contained fluoride. Bactericidal, antiviral, antifungal, and anti-inflammatory activities were indicated, in addition to non-scientific claims such as calming teeth or increasing oral immunity. In total, 72% of products had Instagram profiles, which generally showed low engagement rates (81%) and medium audience quality scores (65%). Twenty-two articles were found in the literature, from which 21 were in vitro studies. The single clinical study was sponsored by a charcoal product and had no control group. In total, 23% of studies showed positive results and 55% reported negative results for the charcoal products, which included no whitening ability, increased roughness, surface alterations, and lower demineralization prevention ability. Altmetric scores for the included articles varied from 0 to 55, with 40.9% of studies mentioned online. In conclusion, charcoal-based products are using marketing strategies on Instagram but their current engagement with the public is not high. Consumers are being exposed to charcoal products whose potential risks to health are still unknown.

The impact of the COVID-19 pandemic on undergraduate and graduate dental courses in Brazil

BACKGROUND

The COVID-19 pandemic has raised challenges in adapting to teaching and learning methods in dental education.

OBJECTIVE

This study aimed to evaluate the impact of the COVID-19 pandemic on the academic activities of undergraduate (UDG) and graduate (GD) dental students in Brazil. Additionally, students' perceptions and attitudes toward teaching activities during this period were analyzed.

METHODS

A nationwide cross-sectional survey was conducted with a sample of Brazilian UDG and GD dentistry students. Data were collected in 2020 through an online, self-administered, and anonymous questionnaire, which comprised 26 questions related to demographic data, activities of the college, family and individual student income, and attitudes and perceptions about e-learning during the pandemic. The data were tabulated and analyzed using descriptive statistics.

RESULTS

The sample included 1,166 students (779 UDG and 387 GD). Among these, 425 (54.6%) UDG and 270 (69.8%) GD students remotely participated in teaching activities, of which 42.6% of the UDG considered their performance in e-learning to be bad or very bad and 49.8% of the GD regarded it as good or excellent. The survey also showed that 354 (45.4%) UDG and 102 (26.4%) GD expressed a desire to discontinue the course following the outbreak of the pandemic. Among the GD, 225 (58.4%) said that their experiments were completely interrupted.

CONCLUSIONS

This study reveals the poor perception and performance of dental students regarding e-learning. Additionally, the findings suggest a negative impact of the pandemic on dental education in Brazil. Effective measures should be taken to mitigate these significant consequences.
