Objective: To analyze the association between sense of coherence and dental caries experience in adolescents. Material and Methods: A cross-sectional study was conducted with 100 adolescents aged 11 to 15 years old who were attending the Debora Feijo State School in the city of Recife (Brazil). Information was collected on sociodemographic data -age, gender, school failure and number of residents per home. Sense of coherence (SOC) was evaluated using the SOC-13 questionnaire and the dental caries experience was determined using the DMFT index. For statistical analysis, the correlation test of Spearman and the association tests of Mann-Whitney and KruskalWallis were used. The significance level was set at 5% (p<0.05). Results: A negative correlation was observed between the SOC and DMFT index (p < 0.001) which indicates that the higher the SOC, the lesser the DMFT. The mean SOC score was greater among adolescents with no dental caries experience. The SOC score was lower among those who failed school more often and those who lived with a greater number of people. Conclusion: The SOC-13 questionnaire can be considered a positive predictor of oral health status, representing an important tool in the establishment of health promotion actions focused on adolescents.

Objective: This study aimed to determine the prevalence of sleep-disordered breathing (SDB) and its association with malocclusion among children in Recife, Brazil. Methods: 390 children aged seven to eight years took part in the study, comprised by the body mass measurement, orthodontic examination and parent's information required by the Sleep Disturbance Scale for Children. Statistics tools were Pearson's chi-square and Lemeshow test. Results: SDB was found in 33.3% of the children and associated with overjet (p= 0.007), anterior open bite (p=0.008) and posterior crossbite (p= 0.001). There was no association between BMI and SDB. The multivariate logistic regression model indicated that the anterior open bite (p= 0.002) and posterior crossbite (p = 0.014) have an association with SDB. Conclusions: Results of this study indicated that the prevalence of SDB was high and highly associated with malocclusion; anterior open bite and posterior crossbite are risk factors for SDB.

AbstractThis study investigated the association between sleep disorders and depression in adolescents, PubMed/MedLine, SciELO and Lilacs databases were consulted, with an interval of 7 years (2013–2019), in English, Portuguese and Spanish. An integrative review was carried out where after analyzing the inclusion criteria, 616 articles were selected for reading titles and abstracts and 94 of these were selected for full reading. After the full reading, 15 articles were elected to be part of this review. Results show that both sleep disorders are risk factors for depression, as depression can be a risk factor for sleep disorders. Insomnia was the most frequent sleep disorder in adolescence, besides being considered a public health problem. It is concluded that sleep disorders and depressive symptoms are associated and present with great frequency in the adolescent public.
