Aim: The aim of the study was to assess the incidence of traumatic tooth injuries in primary school children.
Place and Duration: Conducted in Margalla Dental Hospital, Rawalpindi and Punjab Dental Hospital, Lahore for
duration of six months from September 2019 to February 2020.
Methods: This is a cross-sectional study based on clinical trials. It was held in public and private schools of
Rawalpindi and Lahore. 450 students aged 8 to 11 were selected. Traumatic Dental Injury wasrecorded using
epidemiologic classification adopted by (WHO) 1992 and modified by Andreasen et al. The obtained data was
collected systematically and then subjected to statistical analysis.
Results: The study found that the incidence of traumatic tooth injury (TDI) in Lahore primary schools was 15%,
with the incidence being higher in public schools than in private schools (7.11% versus 6.22%), then higher in 9-
year-olds (6.00%), then 8-year-olds (5.78%). The TDI incidence in the maxilla was greater than in the mandible
(10.22% vs 0.89%), and the most frequently affected front teeth were the medial and lateral incisors. The most
common traumatic injury was enamel fracture (45%).
Conclusion: This study reported a low prevalence of TDI among school-age children and recommended regular
oral health education programs about the causes and methods of preventing TDI.
