Association between bruxism and temporomandibular disorders in children: A systematic review and meta‐analysis

Abstract

Background Bruxism in children and its relation to the development of temporomandibular disorders (TMD) has not been clearly determined yet. Aim The objective of this systematic review was to evaluate the possible association between bruxism and TMD in children. Design Seven databases were searched, and 497 articles were assessed. Methodological quality was assessed through Newcastle‐Ottawa Scale. The meta‐analysis was performed with the articles in which extraction of data was possible and the summary effect measure through odds ratio (OR) and respective 95% confidence intervals (CIs). Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) was used to assess the certainty of evidence. Results Ten cross‐sectional studies were included in the systematic review. Of these, 8 showed a statistically significant association between bruxism and TMD. Seven studies however presented a high risk of bias. The meta‐analysis was performed with 3 articles and obtained an OR of 2.97 (95% CI ranging from 1.72‐5.15), indicating that children with bruxism are 2.97 times more likely to present TMD, with very low level of certainty defined by GRADE. Conclusions Although the studies showed high risk of bias, the qualitative analysis of individual studies showed that the children with bruxism have greater chance of developing TMD.

“…Sobre o tema, uma recente metanálise mostrou que crianças com bruxismo têm 2,97 vezes mais chance de apresentar DTM (Reis et al, 2019). Já uma revisão sistemática demonstrou uma forte relação entre o bruxismo e DTM em indivíduos adultos (Jimenez-Silva et al, 2017).…”

“…25 Çocuklarda bruksizm ve temporomandibular bozukluklar ile iliĢkisi incelendiğinde, bruksizmi olan çocuklarda diğer çocuklardan 2,97 kat daha fazla temporomandibular bozuklukların görülebileceği belirtilmiĢtir. 26 Okul çağı çocuklarında uyku sırasında görülen bruksizm ve baĢ ağrısı incelendiğinde; uyku sırasında bruksizm gözlenen çocukların baĢ ağrısı açısından risk taĢıdığı ve ebeveynlerinin ayrı olduğu çocuklarda bu oranın daha da yükseldiği rapor edilmiĢtir. Sadece uyku sırasındaki bruksizmin baĢ ağrısı ile iliĢkili olduğu, uyanık olunan saatlerde diĢ sıkmanın baĢ ağrısına neden olmadığı da belirtilmiĢtir.…”

Bruxism Management: A Comprehensive Review

“…Over time, a possible association between bruxism and temporomandibular disorders has been discussed in both adults and children, Andrade N, et al [44] investigated the history of sleep, and orofacial disorders in 66 children aged 3 to 7 years, and 34 of them had SB, reporting a possible association between bruxism and orofacial disorders; De Oliveira L, et al [45] also evaluated the possible association between bruxism and temporomandibular disorders and it is evident that children diagnosed with SB have a 2.97 times greater probability of presenting temporomandibular disorders.…”
