Abstract
Background
Individuals with spastic cerebral palsy are more predisposed to parafunctional oral activities and oral motor problems because of spasticity.
Objectives
The aim of the study was to evaluate the relationship between the gross motor function classification system score (GMFCS), age, bruxism, parafunctional oral habits and oral motor problems in children with cerebral palsy.
Methods
This cross‐sectional study included 63 children with spastic cerebral palsy, aged 3–18 years, with developmental disabilities. The relationship between parentally reported bruxism, parafunctional oral activity rates, oral motor problems, and GMFCS was analysed.
Results
The prevalence of bruxism was 52.4%, and the rate decreased as age increased. There was a greater likelihood of bruxism in individuals with tongue thrust (OR [95% CI] = 8.15 [1.4–47.3]) and swallowing problems (OR [95% CI] = 5.78 [1.3–24.68]).
Conclusion
In children with spastic cerebral palsy, bruxism and the rate of parafunctional oral habits were high, thus affecting oral motor activities. A relationship was found between oral motor problems and increased GMFCS levels, but no relationship was found between bruxism and GMFCS levels. Children with spastic cerebral palsy who display tongue thrust or swallowing problems have an increased likelihood of presenting with bruxism.
