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.

Introduction: The epidemiological profile of dental caries for Indigenous Peoples is complex and heterogeneous. The oral health of the Kaingang people, third largest Indigenous population from Brazil, has not been investigated so far. Objective: The purpose of this study was to assess the prevalence and severity of dental caries, in addition to the associated factors of the need of dental extraction among Kaingang adult Indigenous. Methods: A cross-sectional oral health survey was conducted among Kaingang adults aged from 35 to 44 years old living in the Guarita Indigenous Land, Rio Grande do Sul. Clinical exams were performed to analyze the conditions of dental crown and treatment needs. Results: A total of 107 Indigenous adults were examined. Mean DMFT score was 14.45 (± 5.80). Two-thirds of the DMFT score accounted for missing teeth. Anterior lower dentition presented the highest rates of sound teeth, whereas the lower first molars had the lowest. Need for dental extraction was observed in 34.58% and was associated with village location, time of last dental visit, and higher number of decayed teeth. Conclusion: The high frequencies of caries and missing teeth observed in this population indicate a lack of adequate assistance. It is essential to discuss health care models in order to combat avoidable social and health injustices.

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.

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.

To cross-culturally adapt the Oral Mucositis Quality of Life (OMQoL) instrument to Brazilian Portuguese and assess its psychometric properties. The cross-cultural adaptation was performed in six steps. In one of them, the instrument was applied to 40 participants who indicated whether items were comprehensible, which helped elaborate the final version. In the validation phase, 102 participants were interviewed. The sample included patients undergoing oncologic treatment. The softwares R version 4.0.5 and the R Studio 1.4.1717 were used, and the initial database used Dplyr, Tidyr, Gplot2. To assess the psychometric properties, confirmatory factor analysis was performed. The dimensionality of the instrument was investigated using a network analysis approach. The wording of items in a couple of questions were revised after participants indicated a lack of clarity. The relationship between the degree of oral mucositis and the different hospital groups showed statistically significant differences (p<0.001). Confirmatory factor analysis resulted in good index scores (RMSEA=0.08; CFI=0.91; TFI=0.89; CD=0.99), which showed that the instrument had good properties. The OMQoL was translated, adapted and its Brazilian version adequately reflected the original instrument. The OMQoL is valid for the Brazilian population, as well as its short form proposed by this study.
