Research objective: The objective of this study was to investigate the correlation between the level of hyperactivity, impulsivity, and attention deficit, as measured by the ADHD scale, and dental injuries in school-age children. Materials and methods: The research was conducted in schools and clinics through physical questionnaire surveys, involving a total of 396 children ranging from the 5th grade of elementary school to the 4th grade of high school. The questionnaire consisted of three parts. In the first part, the HIP scale was used for the self-assessment of the respondents' psychological characteristics related to hyperactivity, impulsivity, and attention deficit. The second part included specific sociodemographic data, and the final part examined the presence of previous dental injuries. The collected data were processed through quantitative analysis and descriptive statistical analysis techniques using Excel and SPSS software. Results: Out of the 396 participants included in the study, 209 were girls and 187 were boys, aged between 10 and 18 years. 147 of them (37.12%) experienced dental trauma, resulting in a total of 191 injured teeth. 45 participants (30.6%) suffered from various dental and connective tissue injuries. Permanent teeth are affected more frequently than deciduous teeth. (63.95%). The upper central incisor was the most commonly affected tooth (58.5%), followed by the upper lateral incisor (23.81%). Crown fracture was the most frequent type of injury reported (44.9%). The playground was the most common location for injuries (23.13%), and the most common cause of injury was falling (42.9%). Participants who experienced dental trauma had higher self-assessed scores on the HIP scale compared to those who did not. However, neither the cause of injury nor the presence of multiple injuries was associated with elevated HIP scale scores. Conclusion: Based on the results of this research, it is concluded that there is an association between dental traumatic injuries and elevated scores on the HIP scale, indicating that an increased tendency towards ADHD symptoms is connected to dental injuries.
