Summary
Children with sleep bruxism (SB) often continue this behavior into adolescence, leading to increased dental wear. This longitudinal study tracked children
Area of Science:
- Pediatric Dentistry
- Dental Public Health
- Child Psychology
Background:
- Bruxism in childhood can have lasting consequences.
- While often viewed negatively, bruxism may offer protective factors.
- Understanding its long-term effects is crucial for child health.
Purpose of the Study:
- To determine the incidence of sleep bruxism (SB) in children and adolescents.
- To evaluate the association between SB and dental wear over time.
- To identify factors contributing to the development and persistence of SB.
Main Methods:
- A longitudinal study followed 1816 children from 2014/2016 to 2019.
- Sleep bruxism diagnosed via parental and self-reports.
- Clinical assessments included dental erosion and wear; regression models analyzed associations.
Main Results:
- No significant increase in sleep bruxism incidence was observed.
- Children and adolescents showed a 2.2 times higher risk of dental wear.
- Sleep bruxism was linked to earache, erosion, and awake bruxism.
Conclusions:
- Children diagnosed with sleep bruxism tend to maintain the behavior.
- Persistent sleep bruxism is associated with significantly higher rates of dental wear.
- Early identification and management of childhood bruxism are important.
