Traumatic Dental Injuries Among 12-year-old Schoolchildren in Jordan: Prevalence, Risk Factors and Treatment Need
Rajab, Lamis D. / Baqain, Zaid H. / Ghazaleh, Suha B. Abu / Sonbol, Hawazen N. / Hamdan, Mahmoud A. M.
Purpose: To assess the prevalence and related factors of traumatic dental injuries (TDI) among 12-year-old Jordanian schoolchildren.
Materials and Methods: For this cross-sectional study among schoolchildren, a sample of 2560 schoolchildren (1209 boys, 1351 girls) aged 12 years were randomly selected. The epidemiological classification adopted by the World Health Organization (WHO) and modified by Andreasen et al was used to record TDI on incisors.
Results: Of the children examined, 5.5% showed TDI. The difference in prevalence between boys and girls was statistically significant (P < 0.01). Maxillary central incisors were the most affected and the most common type of crown injury was enamel/dentin fracture. The relationship between dental injuries and geographic location, area, and socioeconomic indicators was not statistically significant. Most of the TDI occurred at home, followed by school; the most frequent cause was falls. No statistically significant association was found between TDI and dental caries experience (P > 0.05). There was a tendency for boys (P < 0.01), children with an incisal overjet > 3 mm (P < 0.01) and incompetent lip closure (P < 0.001) to have experienced dental injuries. Treatment need due to dental injuries was very high.
Conclusion: The prevalence of traumatic injuries to permanent incisors in 12-year-old Jordanian schoolchildren was relatively low. TDI was associated with gender, overjet and lip competence, but was not influenced by dental caries experience. There was a great unmet treatment need.
