Abstract
BackgroundMultiple risk factors have been identified for traumatic dental injuries, including crown fractures, in various age groups and various populations. The objective of this study was to determine the prevalence, risk factors and family related factors for crown trauma among 8 to 16 year-old children in a suburban population, Nigeria.MethodsThis is a secondary analysis of a data of 2107 children collected through a school-based survey. Study participants were 8 to 16 year-old resident in suburban Nigeria. The independent variables for the study were age, sex, socioeconomic status, and birth rank, family size and parenting status (one parent, step parent, both parents, and guardians). Details were collected using an interviewer administered questionnaire. Intraoral examination was conducted to identify presence of crown fracture. The independent variables associated with and predictors of crown trauma were determinedusing chi-square and logistic regression analysis respectively.ResultsOnly 167 (7.9 %) of the 2107 study participants had crown trauma. The teeth level prevalence of crown trauma was 0.33 %. Children with middle socioeconomic status had reduced odds of having crown trauma when compared with children with low socioeconomic status (AOR 0.50; CI 0.32–0.80). The odds of having crown traumawas more than doubled in males when compared with females (AOR 2.41; CI 1.72–3.39) and almost doubled in children living with single parents when compared with children living with both parents (AOR 1.94; CI 1.29–3.05).ConclusionsThe prevalence of crown traumawas low in this study population. Being a female and having lowsocioeconomic status significantly reduced the risk factors for crown traumawhile living with single parents increased risk for crown trauma.

Multiple risk factors have been identified for traumatic dental injuries, including crown fractures, in various age groups and various populations
We investigate the association between age, sex, socioeconomic status, birth rank, family related factors and crown trauma, a proxy index for Traumatic dental injuries (TDIs), in school children resident in Ile-Ife, a suburban region in Nigeria
The semi-urban nature of the study environment and the genderisation of roles in a highly patriarchal society like Nigeria increase the likelihood of females being more docile than males, and females being less engaged in contact sports and risky adventures
Summary
Multiple risk factors have been identified for traumatic dental injuries, including crown fractures, in various age groups and various populations. The objective of this study was to determine the prevalence, risk factors and family related factors for crown trauma among 8 to 16 year-old children in a suburban population, Nigeria. Traumatic dental injuries (TDI) are injuries to the oral cavity that often occurs in childhood and adolescence [1]. It comprises about 5 % of all injuries for which people seek treatment [1, 2]. Many studies have reported a higher prevalence of TDI for males due to more male involvement in accident prone events such as aggressive plays, contact sports, and accident prone adventures [8, 9]. The most common aetiology of TDI is falls [12, 13], followed by accidents, violence and sports [14,15,16]
