Prevalence of Sleep Bruxism and Association with Oral Health Conditions in Schoolchildren in a Municipality in Southern Brazil

Abstract

To estimate the prevalence of sleep bruxism and its association with oral health conditions in schoolchildren. Material and Methods: Cross-sectional study carried out in public schools of Tubarão, SC, Brazil with students aged 10 to 15 years. The oral examination was performed in classrooms by dental surgeons, using the WHO criteria. Data on malocclusions, caries and dental trauma, fluorosis, bleeding gums and the presence of dental calculus were collected. For the diagnosis of bruxism, the criterion of the American Academy of Sleep Medicine was adopted. The chi-square test was used to assess the association between sleep bruxism and oral health conditions. Prevalence ratios and confidence intervals were estimated by Poisson regression with robust estimator. Results: A total of 389 students were examined. The prevalence of sleep bruxism was 22.0%. Schoolchildren with malocclusion, increased overjet and dental calculus showed a statistically higher and independent prevalence of 9.0% (p=0.003), 6.0% (p=0.006) and 19.0% (p<0.001), respectively. Conclusion: Prevalence of sleep bruxism was 22% in the study population and was associated with malocclusions, particularly increased overjet, and the presence of dental calculus.

Impact of COVID-19 pandemic on psychological aspects and bruxism in the Brazilian population: observational study

“…with a yet to be discerned multifactorial etiology and complex multisystem physiological processes 30 . There is a need for studies with adequate designs, preferably longitudinal, to elucidate the effects of sleep bruxism on health conditions and the direction of the possible cause-effect relationship between them, if any, since the current literature shows a heterogeneous and inconsistent relationship 31 .…”

Princípios de diagnóstico e tratamento do bruxismo infantil após o aumento desse distúrbio na pandemia

“…(Serra-Negra et al, 2012). Diante de todos os fatores descritos, alguns estudos caracterizam o bruxismo como sendo multifatorial, sendo assim, essa manifestação é a combinação de fatores sistémicos, locais, psicológicos, ocupacionais e hereditários (Traebert et al, 2020). Um estudo foi conduzido para avaliar fatores sociodemográficos e psicossociais associados ao bruxismo em crianças com idade pré-escolar, porém não foram encontradas associações para essas variáveis (Gomes et al, 2018).…”

Prevalence of Malocclusion in Brazilian Quilombola Adolescents

“…Almost all Quilombola adolescents presented malocclusion in need of treatment. Thus, the high prevalence of malocclusion is considered a public health problem and further studies aimed at investigating minority populations and rural areas should be carried out to better understand their characteristics, evaluate possible deleterious habits, since previous researchers have found an association between sleep bruxism [35,36], tongue thrusting, nail-biting, thumb sucking and mouth breathing [36] and malocclusion and, consequently, to understand the oral health needs of these individuals.…”
