Background: ADHD children exhibit a higher risk of dental caries due to dietary factors, irregular eating patterns, and challenges in maintaining proper oral hygiene. A gluten-free diet is one dietary intervention that has gained attention in managing ADHD symptoms. Purpose: Investigates the potential relationship between gluten-free diets and caries in children with ADHD. Reviews: Several studies suggest that children with ADHD on a gluten-free diet may have a lower risk of dental caries due to reduced carbohydrates. Improved dietary habits and enhanced oral hygiene may contribute. However, the impact varies based on diet, oral care, and genetics. The availability of gluten-free products with added sugars poses a potential risk to dental health, emphasizing the importance of considering overall dietary patterns. Conclusion: The increased adoption of gluten-free diets can reducing the risk of dental caries in children with ADHD, but further research is needed to validate the potential relationship between that.
