Prevalence and family structures related factors associated with crown trauma in school children resident in suburban Nigeria.
BACKGROUND
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.


METHODS
This 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.


RESULTS
Only 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).


CONCLUSIONS
The 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.
