Impact of dental bullying on bruxism associated with poor sleep quality among adolescents.

This study aimed to investigate the impact of school bullying and oral health-related verbal bullying on the occurrence of bruxism associated with poor sleep quality among adolescents. This cross-sectional study was nested in a cohort study performed with a sample of children from southern Brazil. Possible sleep bruxism was determined by the question: "Has anyone told you that you grind your teeth in your sleep?" Sleep quality was determined by answering the following question: "How would you classify the quality of your sleep?". The outcome was created by combining occurrence of sleep bruxism and poor sleep quality. The Sense of Coherence (SOC) was assessed using the SOC-13 scale. Bullying was investigated using the victim scale of the Olweus Bullying Questionnaire and oral health-related verbal bullying using an item from the Child Perceptions Questionnaire-11-14. Demographic, socioeconomic, psychosocial, and clinical data were also collected. Poisson regression models with robust variance were used. Results were expressed as prevalence ratio (PR) and 95% confidence intervals (95% CI). A total of 429 adolescents with a mean age of 12.6 (standard deviation 1.3) years were evaluated. The prevalence of bruxism associated with poor sleep quality was 23.7%. Victims of school bullying (PR 2.06; 95%CI: 1.01-4.22) and oral health-related verbal bullying (PR 1.87; 95%CI: 1.18-2.95) presented higher prevalence of bruxism associated with poor sleep quality. Factors such as skin color and SOC were also associated with the outcome. These findings suggest an association between episodes of bullying and bruxism related to poor sleep quality.

Pathways between oral health conditions and bullying on adolescents: A 10-year cohort study.

OBJECTIVE: To assess the pathways in which oral health conditions, socioeconomic, and psychosocial factors in childhood can lead to the occurrence of bullying in adolescence. METHODS: This is a 10-year cohort study conducted with a sample of 639 children in southern Brazil. Oral health conditions (dental caries, dental trauma and malocclusion), sociodemographic and psychosocial characteristics were obtained at baseline (T1) and at follow-up (T2). General and dental bullying were assessed at T2 using the Bullying Olweus questionnaire and through a question contained in the Child Perception Questionnaire 11-14. Structural equation modelling was used to evaluate the pathways between oral health measures and bullying episodes over time. RESULTS: A total of 429 students were evaluated at follow-up. Untreated dental caries were direct and indirectly related with the occurrence of dental bullying at follow-up and indirectly associated with general bullying at T2. Low socioeconomic status, low sense of coherence and dental bullying presented a direct impact on the occurrence of general bullying at T2. CONCLUSIONS: Untreated dental caries are presented as the main oral health predictor of the occurrence of bullying episodes in adolescence.

Effect of individual and neighborhood social capital on gingival bleeding in children: A 7-year cohort study.

BACKGROUND: Social capital incorporates contextual and individual levels of interactions, which influence human health. The aim of this study was to evaluate the influence of individual and contextual social capital in early childhood on gingival bleeding in children after 7 years. METHODS: This 7-year cohort study was conducted with a randomized sample of 639 children (1 to 5 years old) evaluated in 2010 (T1) in Santa Maria, southern Brazil. Gingival bleeding was recorded during follow-up (T2). Contextual (social class association and number of churches) and individual (religious practice, volunteer networks, and school involvement) social capital variables were collected at baseline, along with demographic, socioeconomic, and oral health variables. A multilevel Poisson regression model was used to investigate the influence of individual and contextual variables on mean gingival bleeding. The incidence rate ratio (IRR) and 95% confidence interval (95% CI) were calculated. RESULTS: A total of 449 children were reassessed after 7 years (70.3% cohort retention rate). Children living in areas with a larger number of churches at baseline had lower mean gingival bleeding at follow-up. Regarding individual social capital, children whose parents did not attend school activities were more likely to have gingival bleeding. Additionally, low maternal education, poor parents' perception of oral health, non-use of dental services, and low frequency of tooth brushing were related to higher mean gingival bleeding at follow-up. CONCLUSION: The presence of more churches in neighborhoods and parents' involvement in a child's school activities positively influenced children's oral health, and these individuals had lower mean gingival bleeding.

Do breastfed children have a lower chance of developing mouth breathing? A systematic review and meta-analysis.

OBJECTIVE: Determine the association between breastfeeding and the development of mouth breathing in children. MATERIALS AND METHODS: Seven databases were searched for studies investigating the association between the type of feeding and the development of the breathing pattern in children. Descriptive analysis and meta-analysis were performed, with the calculation of the prevalence and likelihood (odds ratios (95% CI)) of mouth breathing according to the duration of breastfeeding. RESULTS: The overall prevalence of mouth breathing was 44% (95% CI: 38-49) (N total = 1182). Breastfeeding was a protection factor against the development of mouth breathing (OR = 0.62; 95% CI: 0.41-0.93). The likelihood of developing mouth breathing was 41% and 34% lower among children that were breastfed for more than 12 and more than 24 months, respectively. No association was found between exclusive breastfeeding for up to 6 months and the occurrence of mouth breathing (OR = 0.60; 95% CI: 0.31-1.18). CONCLUSIONS: Due to the scarcity of cohort studies that met the inclusion criteria and the low certainty of the evidence, no strong evidence-based conclusion can be drawn. However, breastfeeding should be encouraged due to its possible protective effect, evidenced by the substantial reduction in the prevalence of mouth breathing pattern when performed for up to 2 years. Exclusive breastfeeding was not associated with the development of the breathing pattern. CLINICAL RELEVANCE: The results reveal that breastfeeding can protect children from the development of mouth breathing. Thus, healthcare providers should offer support so that mothers feel prepared and encouraged to perform breastfeeding. TRIAL REGISTRATION: PROSPERO registry: CRD42017062172.

Pathways between toothache and children's oral health-related quality of life.

BACKGROUND: Toothache is considered a multifactorial health problem that is associated with oral diseases and comorbidities. AIM: Evaluate the direct and indirect pathways between toothache and children's oral health-related quality of life (COHRQoL). DESIGN: This is a cross-sectional study conducted with a random sample of children from southern Brazil. The variables included demographic, socioeconomic, behavioral, and oral health characteristics. Toothache was collected through the question 'Have you had toothache in the last 12 months?'. COHRQoL was collected by the Child Perceptions Questionnaire 8-10 in his Brazilian version. The pathways between the associated variables, toothache, and COHRQoL were analyzed through structural equation modeling. RESULTS: A total of 449 schoolchildren were evaluated. The prevalence of toothache was 50.1% (95% confidence interval: 45.4%-54.8%). The poorer COHRQoL was directly affected by the presence of toothache. Considering the indirect pathways, the low household income, high household crowding, low age, the use of public health service, and the untreated dental caries influenced indirectly in the worst COHRQoL via toothache. CONCLUSION: This study determined that COHRQoL was directly influenced by toothache. Meanwhile, indirect pathways were observed. These findings justify initiatives that highlight the importance of the reduction of oral diseases that can lead to pain experiences.

Nível socioeconômico, saúde bucal e fatores associados no suporte social de gestantes: estudo transversal / Socioeconomic level, oral health, and associated factors in the social support of pregnant women: a cross-sectional study

Avaliar a associação entre variáveis socioeconômicas e relacionadas a saúde bucal no suporte social percebido por gestantes. Esse estudo transversal incluiu uma amostra obtida em conglomerados de gestantes atendidas no serviço público de saúde no sul do Brasil. As gestantes responderam questionários acerca de características demográficas, socioeconômicas e relacionadas à saúde bucal. O suporte social foi avaliado através da escala Medical Outcomes Study. As variáveis clínicas incluíram cárie dentária não tratada e sangramento gengival. Análise de Regressão de Poisson em multinível foram utilizados para avaliar a influência dos preditores no suporte social. A amostra foi composta por254 gestantes. Gestantes com pior autopercepção de saúde bucal, níveis extensivos de sangramento gengival e com menor nível socioeconômico apresentaram um pior suporte social. Fatores socioeconômicos e relacionados à saúde bucal exerceram impacto no suporte social percebido por gestantes.

To evaluate the association between socioeconomic and oral health-related variables in the social support perceived by pregnant women. This cross-sectional study included a sample obtained from clusters of pregnant women who attended public health services in southern Brazil. The pregnant women answered questionnaires about demographic, socioeconomic, and oral health characteristics. Social support was assessed using the Medical Outcomes Study scale. Clinical variables included untreated dental caries and gingival bleeding. Multilevel Poisson regression analysis was used to assess the influence of predictors on social support. The sample consisted of 254 pregnant women. Those with poorer self-perceived oral health, extensive levels of gingival bleeding, and lower socioeconomic status, presented poor social support. Socioeconomic factors and factors related to oral health had an impact on the social support perceived by pregnant women.
