The findings of this study suggest a significant association between ADHD and an increased risk of TDIs. Individuals with ADHD were found to be nearly twice as likely to experience TDIs compared to those without ADHD. Efforts should not only be directed towards improving the oral health of this vulnerable group of individuals, but also healthcare practitioners need to be provided with opportunities to create awareness and implement preventive measures to mitigate the risk of TDIs among individuals with ADHD.
