Abstract: (11 Views)
Background and Aims: Bruxism or teeth grinding is a common parafunctional habit childhood that can lead to serious physical and mental complications. The etiology of bruxism remains unclear. However occlusal factors have been suggested as one of several possible contributors that may play a role in its onset.Therefore, the present study was designed to investigate the possible relationship between the occlusal factors and bruxism in children aged from 3 to 6 years old in the city of Ilam-Iran in 2022.
Materials and Methods: This cross‑sectional, descriptive‑analytical study was conducted in 2022. A total of 100 children aged from 3 to 6 years old were selected. During clinical examinations, the following occlusal factors were assessed in relation to bruxism: anterior and posterior crossbite, overbite, and overjet. In addition, a demographic checklist was completed by the parents. The statistical tests, Spearman's correlation index, trend test, and chi-square were used for data analysis in SPSS version 23, with a significance level set at 0.05.
Results: The results of this study showed that among 100 children with bruxism, 48% were boys and 52% were girls. There was a weak correlation between the age and gender with bruxism, which is not statistically significant (p=0.356) and (p=0.412). Flush terminal occlusion was observed in 42% of left-side and 39% of right-side occlusions, and the chi-square test revealed a significant association between this occlusal pattern and bruxism (p=0.001). The highest amount of dental facet (51%) was on enamel, with significant relationship observed between bruxism and anterior and posterior crossbite (p=0.663). However, a significant relationship was found between the bruxism, overbite, and overjet (p=0.003), demonstrating that the increased severity of overbite and overjet correlates with a higher rate of bruxism.
Conclusion: The study concluded that excessive overjet, normal overbite, flush terminal occlusion in both sides, and dental facet were significantly associated with bruxism among occlusal factors.
