RESUMO

ABSTRACT The severe acute respiratory syndrome of the new coronavirus, SARS CoV-2, which became a pandemic, was first reported in Wuhan, Hubei, China, in December 2019. It can cause mild symptoms, but in some cases, it can cause serious complications, leading to death. The disease spreads through aerosol droplets and has an estimated incubation period between 2 and 14 days (a period in which the patient has high potential to infect other people). Endodontists have a high risk of exposure to COVID-19 when compared to other health professionals, since most of the work involves the generation of aerosols and care for patients in emergency situations, such as symptomatic irreversible pulpitis, symptomatic apical periodontitis, acute apical abscess and traumatic dental injuries, is imperative. Thus, this critical review addresses considerations about endodontic care in times of pandemic, whose emergencies imply a real need for treatment, as well as the care that must be adopted to minimize risks for both professionals and patients who seek the resolution of their clinical pain conditions.

RESUMO A síndrome respiratória aguda grave do novo coronavírus, SARS CoV-2, que se tornou uma pandemia, foi relatada pela primeira vez em Wuhan, Hubei, China em dezembro 2019. Pode acarretar sintomas leves, porém em alguns casos pode provocar graves complicações levando o indivíduo ao óbito. A doença se espalha através de gotículas de aerossol e tem um período de incubação do coronavírus estimado entre 2 e 14 dias (período este no qual o paciente tem alto potencial de infectar outras pessoas). Os endodontistas apresentam alto risco de exposição ao COVID-19 quando comparado a outros profissionais de saúde, pois a maior parte do trabalho envolve a geração de aerossóis e os atendimentos a pacientes em situações emergentes, como pulpite irreversível sintomática, periodontite apical sintomática, abscesso apical agudo e lesões dentárias traumáticas são imperativos. Dessa forma, essa revisão crítica aborda considerações sobre o atendimento endodôntico, nesta época de pandemia, cujas emergências imprimem necessidade real de tratamento, bem como os cuidados que devem ser adotados visando minimizar riscos tanto para o profissional quanto para os pacientes que buscam a resolução dos seus quadros clínicos de dor.

RESUMO

ABSTRACT Objective: To analyze the risk behavior for bulimia among female adolescents from public and private high schools. Methods: A cross-sectional study with a random sample of 850 female students aged 15-18 years was carried out in a city in northeastern Brazil, using the Bulimic Investigatory Test of Edinburgh (BITE) to assess the risk behavior for bulimia. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software and the Pearson's chi-square , Fisher's exact and robust Poisson regression tests, adopting the significance level of 5%. Results: Less than half of the sample (42.0%) showed standards of dietary risk and weight control practices; in 1.4% of the sample, bulimia signs were already installed. Fear of gaining weight was reported by 62.8% of the subjects. Risk practices were lower among students from public schools; (Odds Ratio - OR - 0.82; confidence interval of 95% - 95%CI - 0.69-0.97). Among restrictive practices, fasting for a whole day was the most applied (29.9% of the students). Among individuals who were at risk situation, almost half believed to have normal eating habits (prevalence ratio - PR - 0.42; 95%CI 0.36-0.49). Individuals who consider their eating habits normal, who are afraid of gaining weight, those who seek emotional comfort in food and follow strict diets had higher risk for bulimia (p<0.05). Conclusions: The number of female adolescent students with risk behavior practices for bulimia is high, and the frequency of those unaware of this situation is also very high. Risk situations emerge as a collective health problem, and individuals from private schools were more likely to be in this situation.

RESUMO Objetivo: Analisar comportamentos de risco para bulimia em adolescentes do sexo feminino de escolas públicas e particulares. Métodos: Estudo transversal com amostra aleatória de 850 estudantes do sexo feminino, com idades entre 15 e 18 anos, realizado em cidade do Nordeste do Brasil, utilizando o Bulimic Investigatory Test of Edinburgh (BITE) para avaliar comportamentos de risco para transtornos alimentares. Os dados foram analisados utilizando o teste do qui-quadrado de Pearson, o teste exato de Fisher e a regressão de Poisson, com o software Statistical Package for the Social Sciences (SPSS), adotando o nível de significância de p<0,05. Resultados: Da amostra estudada, 42,0% apresentou padrões de risco e práticas de dieta e controle de peso e 1,4% já apresentava sinais de bulimia instalados. O medo de ganhar peso foi relatado por 62,8% das adolescentes. As práticas de risco foram menos frequentes em estudantes de escolas públicas (Odds Ratio - OR - 0,82; intervalo de confiança de 95% - IC95% - 0,69-0,97). Entre as práticas restritivas, jejum por um dia inteiro foi o mais aplicado pelas participantes (29,9%). Entre os indivíduos com situação de risco, quase metade acreditava ter hábitos alimentares normais (razão de prevalência - RP - 0,42; IC95% 0,36-0,49). Estudantes que consideram seus hábitos alimentares normais, que têm medo de ganhar peso, que procuram conforto emocional em alimentos e seguem dietas rigorosas tiveram maior risco para bulimia (p<0,05). Conclusões: O número de estudantes com práticas de comportamento de risco para bulimia é alto, e o número daquelas que desconhecem essa situação também é muito alto. As situações de risco emergem como problemas de saúde coletiva, e indivíduos de escolas particulares são mais propensos a apresentar transtornos alimentares.

RESUMO

The aim of this study was to evaluate whether there is an association between risk behavior for eating disorders (EDs) and dental erosion and caries. A controlled cross-sectional study was conducted in Brazil, involving 850 randomly selected female adolescents. After evaluating risk behavior for eating disorders through the Bulimic Investigatory Test of Edinburgh, 12 adolescents were identified with severe risk behavior for EDs and matched to 48 adolescents without such risk. Dental examinations, anthropometric measurements, and eating habits and oral hygiene were performed. Adolescents with high severity eating disorder condition were not more likely to show dental caries (p = 0.329; OR = 2.2, 95% CI: 0.35-13.72) or dental erosion (p = 0.590; OR = 2.33; 95% CI: 0.56-9.70). Adolescents with high body mass index (BMI) were five times more likely to have high severity eating disorder condition (p = 0.031; OR = 5.1; 95% CI: 1.61-23.07). Therefore, high severity risk behavior for EDs was not significantly associated with dental caries and dental erosion. However, high BMI was a risk factor for developing eating disorders and should be an alert for individuals with this condition.

RESUMO

Objective: To evaluate the relationship between nutritional status and dental caries in Brazilian female adolescents with and without behavioral risk for eating disorders. Material and Methods: Cross-sectional study involving 60 girls, 15 to18 years old, randomly selected from public and private schools. Risk behavior for eating disorder was assessed by the Bulimic Investigatory Test of Edinburgh, anthropometric measurements were taken to calculate the body mass index, dental examinations were performed to verify the caries experience and a questionnaire to collect sociodemographic data was applied. Data were analyzed descriptively and analytically using the Statistical Package for the Social Sciences 18.0 software. The level of statistical significance was set at 5%, with a 95% confidence interval. Results: Most of the girls studied in public school (75,0%), had no partner (95,0%) and had a monthly family income above the minimum wage (63,3%). The prevalence of dental caries was high (86.7%). The most used practice for weight loss was the act of purge (18.3%). There was no statistically significant association between dental caries and Body Mass Index (p=0,655), however, it was observed that adolescents with high Body Mass Index had a higher risk for Eating Disorders (p<0,05). Conclusion: The nutritional status was not associated with dental caries, however the monitoring of girls with high Body Mass Indexis important due to the increased risk of eating disorders.
