Associação entre problemas para dormir e condições orais em escolares / Association between trouble sleeping and oral conditions among schoolchildren

ABSTRACT Objective: To investigate the prevalence of self-reported trouble sleeping due to dental problems and its association with oral conditions in schoolchildren. Methods: This is a cross-sectional study carried out with a representative sample of 1,589 schoolchildren aged 8-10 years enrolled in public schools from Florianópolis, Santa Catarina, Brazil. Non-clinical data included a questionnaire about socioeconomic indicators answered by parents/guardians. Children were questioned about whether they had trouble sleeping due to dental problems and about previous history of toothache. Clinical oral examinations were performed to evaluate dental caries - Decayed, Missing, and Filled Teeth Index (DMFT/dmft index) and its clinical consequences [PUFA/pufa index: considering the presence of pulpal involvement (P/p); ulceration of tissues due to tooth fragments from decayed crowns (U/u); fistula (F/f); and abscesses (A/a), and traumatic dental injuries (TDI)]. We conducted a descriptive analysis and used adjusted logistic regression models (p<0.05; 95%CI). Results: The prevalence of trouble sleeping due to dental problems was 28%. Children with untreated dental caries (OR 1.32; 95%CI 1.05-1.67) and clinical consequences from the PUFA/pufa index (OR 1.89; 95%CI 1.45-2.46) had higher chances of reporting trouble sleeping due to dental problems. Conclusions: Approximately one-third of the children declared having trouble sleeping due to dental problems. Untreated dental caries and its clinical consequences were associated with self-reported trouble sleeping due to dental problems in schoolchildren.

RESUMO Objetivo: Investigar a prevalência de problemas para dormir por motivos dentários autorrelatado e sua associação com condições orais adversas em escolares. Métodos: Estudo transversal com amostra representativa de 1589 escolares de 8 a 10 anos matriculados em escolas públicas de Florianópolis, Brasil. Os dados não clínicos incluíram um questionário sobre indicadores socioeconômicos respondidos pelos pais/cuidadores. As crianças foram questionadas se tinham problemas para dormir por motivos dentários e sobre episódios anteriores de dor de dente. Foram realizados exames clínicos orais para avaliar: cárie dentária - Índice de Dentes Cariados, Perdidos e Obturados (índice CPO-D/ceo-d) - e suas consequências clínicas (índice PUFA/pufa - presença de envolvimento pulpar (P/p); ulceração (U/u); fístula (F/f); e abscessos (A/a) e traumatismo dental (TD). Foram realizados análise descritiva e modelos ajustados de regressão logística (p<0,05; IC95%). Resultados: A prevalência de problemas para dormir por motivos dentários foi de 28%. Crianças com cárie dentária não tratada (OR 1,32; IC95% 1,05-1,67) e presença de índice PUFA/pufa (OR 1,89; IC95% 1,45-2,46) apresentaram maiores chances de relatar problemas para dormir devido a razões dentárias. Conclusões: Aproximadamente, um terço das crianças apresentou problemas para dormir devido a razões dentárias. Cárie dentária não tratada e suas consequências clínicas foram associadas a problemas autorrelatados para dormir por motivos dentários em escolares.

Association of gender, oral habits, and poor sleep quality with possible sleep bruxism in schoolchildren

Abstract The aim of this study was to verify the oral habits, symptoms, and characteristics of some children aged 8 to 10 years that could be associated with possible sleep bruxism. A cross-sectional study was performed. Questionnaires were sent to parents to obtain information on sex, age, school shift, sleep quality, parents' perception of children's behavior, and children's oral habits (nail biting, object biting, and lip biting), and symptoms such as headache or earache. In addition, parents reported the frequency of sleep bruxism (no day to 7 days a week). Descriptive analysis and multinomial logistic regression were performed and the level of significance was set at 5%. A total of 1,554 parents of children aged 8 to 10 years participated in this study. Possible sleep bruxism was reported as mild for 65.7%, moderate for 25.3%, and severe for 9% of the children. In the adjusted multinomial logistic regression, boys were 79% more likely to have sleep bruxism (OR: 1.79; 95%CI 1.23-2.60) and were 2.06 more times at risk of being in the habit of lip biting (OR: 2.06; 95%CI 1.26-3.37). Children with possible severe sleep bruxism were 61% more likely to develop object biting (OR: 1.61; 95%CI 1.09-2.39), 52% more likely to have headaches (OR: 1.52; 95%CI 1.01-2.28), and 3.29 more times at risk of poor sleep quality (OR: 3.29; 95%CI 2.25-4.82). Based on the report, boys with lip and object biting habits, headaches, and poor sleep quality presented a higher chance of possible severe sleep bruxism.
