The association of childhood sleep problems with the prevalence of traumatic dental injury in schoolchildren

Abstract

Background/Aim Sleep quality exerts an influence on attention level and motor skills and is associated with accidental injuries in children. The aim of this study was to evaluate the association between traumatic dental injury and sleep behaviour in children. Material and Methods A cross‐sectional study was conducted in a small city in southern Brazil with a representative sample of schoolchildren aged 8‐10 years (n = 537). Weight and height were measured, and examinations were performed for the determination of clinical occlusion and traumatic dental injury. The parents answered the Sleep Behaviour Questionnaire and questions addressing socio‐demographic characteristics. Results The prevalence of traumatic dental injury was 22% (95% CI: 19‐26) and was higher among children who woke three to four times per night (PR = 3.30; 95% CI: 2.47‐4.39), those who fell asleep in the parental bed (PR = 1.41; 95% CI: 1.09‐1.83), those who were not in a good mood on waking up in the morning (PR = 1.30; 95% CI: 1.02‐1.65), those who became sleepy while sitting and/or studying (PR = 1.57; 95% CI: 1.09‐2.24) and while watching TV (PR = 1.41; 95% CI: 1.0005‐1.97) and those who had bad dreams (PR = 1.35; 95% CI: 1.04‐1.76). The Poisson multiple regression model with a multilevel approach revealed that the prevalence of traumatic dental injury was 1.51‐fold higher among children with daytime drowsiness (PR = 1.51; 95% CI: 1.11‐2.04) after adjusting for socio‐demographic, occlusal and anthropometric variables. Conclusion Sleep problems were associated with a higher prevalence of traumatic dental injury among the children analysed.

Clarifying the effect of refractive errors and stereopsis on traumatic dental injuries in childhood

“…Several studies that have examined the etiology of traumatic dental injuries in childhood and adolescence have shown that falls and crashes that occur during physical activities and sporting activities are among the main reasons 20‐22 . Several studies have investigated traumatic dental injuries and found correlations of varying degrees between dental injuries resulting from falls and orofacial region anatomy (eg, increased overjet and short frenulum), anthropometric measures (eg, obesity), behavioral structure (eg, hyperactivity, peer bullying, sleeping disorders), and certain drugs (eg, methylphenidate) 23‐32 . Although it is reasonable to suppose that children with visual impairments and decreased depth sensation are more susceptible to accidents and falls, the relationship between stereopsis and visual impairment and TDI have not previously been investigated.…”

[23][24][25][26][27][28][29][30][31][32] Although it is reasonable to suppose that children with visual impairments and decreased depth sensation are more susceptible to accidents and falls, the relationship between stereopsis and visual impairment and TDI have not previously been investigated. This study determined whether a connection exists between vision defects and the resulting loss of stereopsis on the one hand and dental injuries on the other.…”

Is there a relation between sleeping habits and nocturnal bruxism, temporomandibular disorders, dental trauma and caries among children?

“…The relationships between sleeping habits and possible TMJ problems, malocclusion, TDI, bruxism and dental caries have been investigated recently and still holds a major area of research interest. (15)(16)(17) In this study, Turkish Version of CSHQ was used for data colletion. This questionnaire was translated to Turkish and validated and reported to be a reliable instrument for assessing sleep habits and screening possible sleep problems of Turkish children.…”

“…A bad night sleep can affect a person's mood and concentration the next day. (17) It was stated that sleep deprivation was associated with accidental injuries; 86% increase in trauma incidences when children slept less than 10 hours the night before the accident. (28) In addition, waking up three to four times at night, which is an indication of agitated sleep, was associated with a higher traumatic dental injury prevalence.…”

“…This might increase the frequency of dental trauma incidence. (16,17) Considering sleep problems are common in the pediatric population, its potential relation with bruxism, tmd, tdi and dental caries are in scope of researchers' interest. Therefore, the aim of this study was evaluate the possible association between sleeping habits, bruxism, temporomandibular disorders (TMD), traumatic dental injuries (TDI) and dental caries through CSHQ in children aged between 6-13 years.…”
