TRAEBERT, J.; ALMEIDA, I. C. S.; GARGHETTI, C.  and  MARCENES, W.. Prevalence, treatment needs, and predisposing factors for traumatic injuries to permanent dentition in 11-13-year-old schoolchildren. Cad. Saúde Pública [online]. 2004, vol.20, n.2, pp.403-410. ISSN 1678-4464.

The objective of this study was to assess the prevalence of traumatic injuries to the permanent incisors and the association with clinical predisposing factors and parents' schooling. A cross-sectional survey was conducted with schoolchildren aged 11 to 13 years in Biguaçu, Brazil. Dental examinations were conducted by a dentist, and the criteria for traumatic dental injuries used in the children's dental health survey in the United Kingdom were adopted. the study recorded the type of damage sustained, treatment performed or needed, the size of incisal overjet, and whether lip coverage was adequate. Socio-demographic data included sex, age, and parents' level of schooling. a total of 2,260 children were examined, and prevalence rates were 10.4%, 10.6%, and 11.2% in 11, 12, and 13-year-old children, respectively. Treatment need was 6.3 interventions per thousand incisors. Male gender and overjet greater than 5mm were significantly related to having a traumatic dental injury. Inadequate lip coverage and parents' educational level were not associated with dental trauma. The study concluded that male gender and incisal overjet greater than 5mm are associated with the occurrence of dental injury.
