The prevalence of traumatic dental injuries was 23.2% (24% in boys and 22.3% in girls) Boys experienced more injuries than girls but the difference was not statistically significant p> 0.05. The largest percentage of injury was demonstrated by 5 year old children. The most common type of injury was enamel fracture 53.9%, followed by enamel-dentine fracture 19.2% and concussion 17.3%. The maxillary central incisor was the most vulnerable tooth to injuries 76.9%. The study showed a decline in the prevalence of traumatic dental injuries among suburban Nigerian children in Ile – Ife.
