Background: Traumatic injuries, especially fracture of anterior teeth are a tragic but often ignored problem among young children. There is perhaps no single dental disturbance that has greater psychological impact on both parent and the child than the loss or fracture of child's anterior teeth. Multiple causes contribute to tooth trauma, with the major focus on falls and collisions, sporting activities, domestic violence, automobile accidents and assaults. Aims & objectives: To know the prevalence of traumatic injuries to permanent anterior teeth among 8-15 years old government and private school children in Bangalore city. Materials & methods: Study group consisted of 2000 government and private school children between the ages of 8-15 years old in Bangalore city selected by simple random sampling. The study was conducted from January 2008 to July 2008. Information regarding patient's demographic profile and any history of trauma affecting permanent teeth were recorded using structured proforma. The data was then processed and analyzed using the chi square test and the student t test (p value 0.05). Results: The prevalence of anterior tooth trauma was 14.5%. The prevalence of tooth trauma in private school children was 15.9% and in government school children was 13.0%. More of boys (17.3%) had history of trauma than girls (11.4%). The maxillary central incisors were most commonly involved by trauma (89.6%). Maximum teeth involved by trauma had fractures confined to enamel (81.6%). The main cause of trauma was indoor falls (27.3%). The trauma occurred most frequently at home (35.4%). The frequency of injuries was 7.9% in children with normal overjet (0-3 mm), 49.6% in children with increased overjet (3.1-6mm) and 54.2% in children with extreme overjet ( 6 mm). Among children with traumatized teeth 78.5% had type I malocclusion. Conclusion: The prevalence of traumatic injuries to permanent anterior teeth was higher among private school children compared to government school children. Also, the prevalence of traumatic injuries was more among children with increased maxillary overjet, in children with type I malocclusion, and more in boys when compared to girls.
