Abstract
Background Traumatic dental injuries represent nearly 5% of children and adolescents' injuries leading to serious medical and psychological issues. This current study aims to evaluate the prevalence of dental trauma and its potential association with different predisposing factors among 12-and 15-year-old schoolchildren in Lebanon. Materials and Methods 7902 schoolchildren, 3806 male and 4096 female aged 12 years (n = 3985) and 15 years (n = 3917), were recruited by a stratified multistaged randomized cluster sampling method from public and private schools and were clinically examined in a national cross-sectional study. WHO criteria were used to assess anterior permanent teeth; the nature of trauma, the tooth involved, the size of the incisal overjet, and the type of the lip coverage were furthermore assessed. Data regarding age, sex, and causes of TDI were recorded through a structured questionnaire. Results The prevalence of dental trauma to anterior teeth was 10.9%. Maxillary central incisors (83.7%) were commonly affected. The most common type of injury was enamel fracture (68.3%), falls being the main reason (52.5%). Increased overjet (OR = 2.32, p = 0.034), deficient lip coverage (OR = 5.73, p = 0.019), and gender (OR = 5.36, p ≤ 0.001) were significant predisposing factors for dental trauma. Conclusion This research highlighted many predisposing factors for dental trauma that affect commonly the anterior teeth. Based on these results, the implementation of strategic preventive measurements targeting especially the identified risk groups remains crucial.
Highlights
Traumatic dental injuries (TDIs) are listed among the most common injuries occurring during childhood and adolescence, highly vulnerable periods for dental trauma [1].Approximately 25% of all schoolchildren and adolescents between 7 and 19 years have suffered from a type of TDI involving their permanent dentition [2, 3].Nowadays, TDI is considered a challenging public health concern [4, 5] with a great impact on a person’s quality of life since it could be a potentially life-changing accident.According to epidemiological research, the prevalence of traumatic dental injuries varied from one country to another
7902 participants (3806 boys and 4096 girls) were included in the study. e examined sample was almost distributed into individuals aged 12 years (50.4%) and 15 years (49.6%). 56.1% and 43.9% of the participants were recruited from private and public schools, respectively, and the vast majority live in a suburban area (63.0%). e prevalence of TDI was 10.4% with 823 children showing signs of previous TDI
E majority of the accident that led to TDI took place at home (72%), followed by schools (21%) and other locations as playgrounds and streets (7%)
Summary
Traumatic dental injuries (TDIs) are listed among the most common injuries occurring during childhood and adolescence, highly vulnerable periods for dental trauma [1]. 2. Materials and Methods is school-based national retrospective study was conducted in the six governorates of Lebanon, from September 2018 to June 2019, among 12-year-old (n 3985) and 15year-old (n 3917) schoolchildren selected from public and private secondary schools located in the urban, suburban, and rural areas.

E sample size was calculated based on the number of students in grade VII and grade X registered in private and public Lebanese schools according to the Ministry of Education and Higher Education. Statistical significance was set at a value of less than 0.05
