"The study was conducted to find out the prevalence of dental traumatic injuries to maxillary and mandibular primary and permanent anterior teeth of Chandigarh school children aged 5-17 years. A total of 11 schools of high medium and low socioeconomic strata of urban areas and two schools of rural areas of Chandigarh were included for evaluation," said Dr Ashima Goyal, pediatrics dentist, PGI.

She further said, "In phase 1 of the study, 11,538 subjects were screened for any kind of dental traumatic injuries. The children were then asked to visit the unit of pedonotics and preventive dentistry, PGI for a detailed clinical and radio-graphic evaluation as part of phase 2 of the study."

The results of the study shows that 1047 out of the total 11,538 children, had fractured upper or lower deciduous or permanent anterior teeth, giving a prevalence rate of 9.07%. Further, crown fractures were the most common traumatic injury in the permanent and deciduous dentition.

Boys (10.18%) showed more traumatic injuries than girls (7.85%). It was also observed in the study that prevalence of injuries increased with increasing age, with maximum traumatic injuries in 13-17 year old children.
