Socioeconomic inequalities in the use of dental services in Brazil: an analysis of the 2019 National Health Survey

Oral manifestations of syphilis: Knowledge and skills of senior dental students and newly graduated dentists

OBJECTIVES

To evaluate the knowledge of senior dental students and newly graduated dentists about the prevention, diagnosis and treatment of oral manifestations of syphilis.

MATERIALS AND METHODS

A 32-question questionnaire was designed with three domains: (I) demographic, academic and professional data of the participants, (II) attitudes, practices and self-perception regarding training about syphilis and (III) knowledge about syphilis. All knowledge responses were classified as correct or incorrect. Scores ranging from 1 to 14 were calculated, and grades were assigned to each participant according to their level of knowledge.

RESULTS

The sample comprised 408 dental students and 339 newly graduated dentists. The mean score was 7.70 ± 3.35 for undergraduates and 9.09 ± 3265 for dentists. The highest frequency of correct answers (>70%) was attributed to questions about the aetiology, transmission and treatment of syphilis. The questions with the lowest frequency of correct answers (<50%) were about the identification of oral manifestations and stages of syphilis.

CONCLUSIONS

The knowledge of dental practitioners and academics about the oral manifestations of syphilis was unsatisfactory. The lack of understanding of these aspects can delay the diagnosis and treatment of patients with this disease, which is concerning given the steady increase in cases in recent years.

Relationship between the Social Development Index and Self-Reported Periodontal Conditions

Inequalities in oral health are influenced by the social strata of the population. Few studies have focused on the multitude of factors related to social development as indicators of living conditions and periodontal health status. The aim of this study is to evaluate the association between self-reported periodontal conditions and the Social Development Index (SDI). A cross-sectional validated questionnaire was carried out among 1294 Mexican adults. Descriptive statistics and multivariate logistic regression models were used to identify the best predictors of self-reported periodontal conditions. Bone loss reporting was used as a proxy for the presence of periodontal disease. We found that higher global scores on the SDI and quality and available space in the home (QASH) increase the probability of having bone loss. Global SDI (OR = 7.27) and higher QASH (OR = 3.66) were indeed the leading societal factors related to periodontal disease. These results have pointed out how SDI and its indicators, in particular QASH, can be used to further explore inequities related to privileged access to dental care in the context of periodontal diseases.

Factors associated with recent and regular non-use of dental services by students from a university in southeastern Brazil: a cross-sectional study

BACKGROUND

Lack of use of dental services can be a risk factor for oral health. In addition to recent visits to dental services, it is important to assess the regularity of use of these services, as well as the motivations for visiting the dentist. There is a gap in literature studies on the patterns of use of oral health services by the young university students. The goal of this study was to assess the factors associated with recent and regular non-use of dental services by young university students, using the Andersen model as a reference.

METHODS

This was a cross-sectional study with 477 university students between 18 and 24 years old, carried out as a web survey, through which predisposing, enabling and need variables were collected, according to the model proposed by Andersen, to test the factors associated with recent and regular non-use of dental services. Bivariate analyses and robust Poisson regression were performed, with estimation of crude and adjusted prevalence ratios, using confidence intervals of 95%. The variables with p < 0.05 remained in the final model.

RESULTS

The prevalence of recent non-use was of 19.5% (95% CI 16.0-23.3%), and of regular non-use, of 53.5% (95% CI 48.9-58.0%). After the adjusted analysis, the following were found to be associated with the outcome of recent non-use: type of service used (PR = 0.91; 95% CI 0.85-0.98) and perceived need for dental treatment (PR = 0.98; 95% CI 0.97-0.99); and the following variables were associated with regular non-use: father's level of education (PR = 0.86; 95% CI 0.78-0.96), area of study (PR = 1.08; 95% CI 1.02-1.15), reason for last dental appointment (PR = 0.81; 95% CI 0.75-0.88), use of dental services throughout childhood (PR = 0.92; 95% CI 0.86-0.97), self-perceived oral health (PR = 0.86; 95% CI 0.76-0.88), and toothaches over the last 2 years (PR = 0.93; 95% CI 0.87-0.99).

CONCLUSION

The motivation for young university students to use dental services are curative treatment needs, not prevention. The results point to the need to implement health prevention and promotion policies in higher education institutions and to expand access to dental services for this young population.

Toothache and tooth extraction as reasons for dental visits: an analysis of the 2019 National Health Survey

The aim of this study was to analyze the prevalence of dental visits due to toothache and tooth extraction in Brazil and its association with individual and contextual variables. This two-step cross-sectional study included persons aged 18 years and older in the 2019 National Health Survey who had visited a dentist in the 12 months prior to the interview (n = 40,369). The individual-level outcome was having a dental visit due to toothache or tooth extraction. The ecological-level outcome was the proportion of dental visits for these reasons relative to all dental visits by Brazilian state. Associations with individual - sociodemographic characteristics, number of teeth, and type of health service used - and ecological variables - HDI and dental service coverage - were assessed using Poisson regressions. The prevalence of dental visits due to toothache or extraction was higher among individuals with no formal education, household income < 25% of the minimum wage, of black and brown skin color, living in rural areas, who consulted in the public health system, with 10-19 and 1-9 teeth, and men. The proportion of dental visits due to toothache/extraction in Brazilian states was negatively associated with the HDI and the rate of dental emergency team/100,000 inhabitants and positively associated with primary dental care coverage. The prevalence of dental visits due to toothache/extraction was associated with individual and ecological characteristics, indicating inequities in reasons for dental visits in Brazil. The potential of a well-structured oral health care network to overcome these inequities is suggested and needs to be better explored.
