Children and adolescents with ADHD are more likely to have dental trauma; however, due to the limitations of the data, a causal relationship cannot be established.

Attention-deficit/hyperactivity disorder (ADHD) affects approximately 7.2% of children and adolescents worldwide. This study aimed to assess whether children and adolescents with ADHD were more likely to have dental trauma when compared to their healthy peers. The literature was searched until October 2022 and observational studies with a control group were eligible. A meta-analysis was performed. A total of 239 studies were detected; of these, six were included in the qualitative synthesis and four were merged in the meta-analysis. The risk of bias was high. The strength of the evidence was 'very low'. Children and adolescents with ADHD are more likely to have dental trauma than their non-ADHD peers. However, due to limitations in the design of the included studies, a causal relationship cannot be established.
