Aim: This study aimed to identify the prevalence of traumatic dental injuries in a group of Egyptian children with special health care needs aging 6-14 years; investigating types, causes, risk factors associated with dental trauma, and factors related to treatment.

Methodology: The study was conducted through questionnaires for parents and clinical examinations. 763 children with (autism, attention deficit hyperactivity disorder, cerebral palsy, Down syndrome, epilepsy, hearing impairment, intellectual disability, motor difficulty, and visual impairment) had been examined in fourteen places, including the Pediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Cairo University, schools, centers, and charity organizations in three governments. Data concerning demographics, causes, types, risk factors associated with dental injuries, and treatment-seeking behavior were collected.

Results: The prevalence of traumatic dental injuries in children with special health care needs was 12.8% (98 children). The prevalence was highest among children with intellectual disability (49%), followed by epilepsy (18.4%). Males are more prone to traumatic dental injuries than females. The upper central incisors had the highest frequency of injury (89.7%), and enamel fracture was the most frequent type (51.8%). Falling was the most common cause of

dental injuries (69.4%), and the most frequent place of trauma was at home (48.0%). Inadequate lip coverage, increased overbite, anterior open bite, and increased overjet were significant risk factors associated with traumatic dental injuries. 73.5% of children did not seek dental advice, and the most frequent reasons for not seeking treatment included parental attitude and lack of dental awareness.
Conclusion: The study showed a significant association between traumatic dental injuries and intellectual disability, epilepsy, Down syndrome, and autism. The main reasons for not receiving dental treatment were poor parental attitude, and lack of dental awareness.
