Objective: To investigate the association between emotional and behavioural problems and dental fear/anxiety (DFA) in children aged four to 12 years treated at a clinic in southern Brazil. Material and Methods: In this cross-sectional study where mother-child dyads were interviewed, emotional and behavioural problems were investigated using the Strengths and Difficulties Questionnaire (SDQ) (considering five subscales). Children's DFA was evaluated through the Venham Picture Test. For each SDQ subscale, Poisson regression model was explored. Prevalence ratios (PR) were estimated, considering a significant level of p ≤ 0.05. Results: Overall, 128 children participated in this study. Most children were female (54.7%) and aged between 7 and 9 years (39.8%). The prevalence of emotional problems was 47.7% and behavioural problems were 46.1%. The prevalence of DFA was 18.8%. Children with emotional problems had a 2.3 higher prevalence of DFA (95%CI 1.06-5.04). In general, behavioural problems were not associated with DFA (95%CI 0.84-3.34) only when conduct problems were considered (2.20; 95%CI 1.02-4.70). Conclusion: Children aged between 4 and 12 years who present emotional and conduct problems tend to show higher DFA. [ABSTRACT FROM AUTHOR]

Objective: To translate and perform the cross-cultural adaption of the CD:H scale for use in Paediatric Dentistry in Brazilian Portuguese language. Material and Methods: The translation and cross-cultural adaptation of the CD: H was carried out in four stages: 1) translation of the instrument; 2) reverse translation (back translation); 3) cross-cultural adaptation, and 4) face validation. Face validation consisted of the evaluation of 30 subjects from the target population. A pilot study was conducted with 15 children aged 5-10 years treated at a university dental clinic and their drawings were analysed by two dentists. Data were analysed using Stata 12.0. Results: In the face validation, most items were understood; however, some words were changed, and terms were included to identify the dental environment. Good reproducibility was obtained: inter-examiner reliability was 0.9647 and intra-examiner reliability was 0.9619 for examiner A and 0.8260 for examiner B. Conclusion: The Brazilian version of the CD:H scale is a useful tool for dentists, helping identify children's emotions and being enjoyable for them. [ABSTRACT FROM AUTHOR]

Aim: To verify the validity of maternal reports on the number of deciduous teeth erupted in their children. Methods: This cross-sectional study was performed with children enrolled in a Birth Cohort at the age of 12 months in the first stage and 24 months in the second stage. At both stages, children were clinically examined, and mothers reported the number of teeth of their children. Comparison between groups was performed using the Mann-Whitney non-paired Wilcoxon test. Level of agreement between two methods were estimated by the Observed Agreement, Weighted Kappa and Intraclass Correlation coefficients. Results: A total of 125 children were examined in the first stage, with mean number of reported teeth of 6.2. In the second stage, 149 children were examined, with mean number of reported teeth of 15.9. High level of agreement, kappa values and intraclass correlation coefficients were observed for both arches in both periods (p<0.001). Conclusions: Maternal report on the number of teeth erupted in children was reliable and valid. Thus, it seems to be a useful instrument for collecting data in population-based epidemiological studies targeting young children. [ABSTRACT FROM AUTHOR]

Mood disorders such as stress and depression can promote alterations of several hormones Aim: The present study aimed to evaluate if symptoms of depression and stress are associated with halitosis. The hypothesis is that halitosis is associated with stress and depression symptoms. Methods: All university students' entrants in the Federal University of Pelotas (UFPel) were invited to participate. Self-reported halitosis was measured using a visual analog scale. Students were also asked about the presence of halitosis perceived by close individuals. The stress level was measured using a modified version of the Perceived Stress Scale and symptoms of depression were screened by Patient Health Questionnaire-2. Poisson Regression Models were performed. Results: Of a total of 2,058 students who participated in the study, only 16% of them have reported not having any degree of halitosis and 17.6% were informed of closed individuals having halitosis. After adjustments, stress and depression symptoms remained associated with halitosis selfreported. Individuals from the higher stressed quartile presented higher scores of halitosis (RR 1.37 CI95% [1.24-1.53]). Students who presented depressive symptoms showed higher scores of self-perceived halitosis (RR 1.20 CI95% [1.10-1.32]). When the association of stress and halitosis reported by close individuals was tested, symptoms of depression lost the association in the adjusted model, while individuals from the highest quartile from stress remained associated (PR 1.36 CI95% [1.02-1.81]). Conclusion: Halitosis was associated with stress even after control for oral health and socioeconomic variables. [ABSTRACT FROM AUTHOR]

Aim: To investigate the association between obesity, overweight, and tooth loss due to caries among university students of (Federal University of Pelotas) in southern Brazil. Methods: A cross-sectional study with all first-year students who regularly enrolled in the first semester of 2016 who were invited to respond to a self-administered questionnaire contain socioeconomic and demographic; psychosocial; oral health; behavioral questions. The body mass index (BMI) was calculated through the self-reported data of weight and height. The main outcome of the present study was determined by the person's that answer having had at least one tooth extracted due to caries. A Poisson regression using a backward stepwise procedure was performed. Two models were tested: i) including socioeconomic and behavioral variables; ii) without behavioral variables. Results: From 3,237 eligible students, 2,089 (64.5%) participated in the present study. Almost 23% of students presented overweight and 8.4% obesity, whereas 362 individuals (17.5%) reported having had at least one tooth extracted due to caries. Regarding the final model adjusted by behavioral variables, it was observed that obese university students presented a 32.0% higher prevalence of tooth loss (PR=0.32, CI95%[1.17-1.49]). However, overweight was not associated with tooth loss in the present sample. When the model was not associated with behavioral variables, overweight was associated with tooth loss (PR=1.44; CI95%[1.15-1.81]), just as obesity (PR=2.13; CI95%[1.63 - 2.78]). Conclusions: Obesity and overweight were associated with tooth loss due to caries in the present sample of university students. [ABSTRACT FROM AUTHOR]
