Prevalence of traumatic crown fractures to permanent incisors in a childhood population: Móstoles, Spain.
- The aim of this study was to ascertain the prevalence of traumatic crown fractures in a childhood population and identify the risk factors associated with the same. A cross-sectional study was conducted, covering 470 schoolchildren and surveying socio-demographic variables, overweight, overbite, number of teeth, cause, setting, season, type of injury and restoration. We measured prevalence, performed univariate and multivariate analyses of risk factors for crown fracture, and calculated the Odds Ratio (OR) and its 95% confidence intervals (95% CI). Prevalence of traumatic crown fractures to permanent incisors was 17.4% (95% CI: 14-20.8). Falls were the most frequent cause of dental trauma (43.9%). Boys and children with overbite registered a 2.13- and 1.81-fold higher risk of crown fractures, respectively. Owing to high prevalence, crown fractures in schoolchildren aged 10 years constitute a public health problem. Being male and having overbite are risk factors for crown fracture. Healthcare promotion and education at health centres is called for to prevent such injuries.
