Can dentists contribute to early screening for developmental disorders in five-year-old children during health checkups?

Aim: This study aimed to clarify the relationship between developmental disorders and oral function assessed using the mouth rinsing function test (MRFT). Materials and methods: A total of 1147 children who underwent health checkups between 2014 and 2017 were included. We divided the patients into two groups based on their MRFT findings: good and poor oral function. We analyzed the associations between the outcomes of MRFT and other assessments using the chi-squared test and multiple variable logistic regression analysis. Results: Of the 1147 participants, 346 (30.2%) were suspected of having developmental disorders, 951 (82.9%) had good oral function, and 196 (17.1%) had poor oral function. Statistical analysis demonstrated significant differences in developmental disorders and oral function. Children suspected of having developmental disorders had significantly poor oral function. Conclusions: Dentists can detect early signs of developmental disorders using MRFT owing to its convenient performed in dental clinics. Developmental disorders possess spectrums of symptoms and various accompanying conditions; therefore, collaboration with other professionals is crucial for early screening and child support during their development.
