Abstract
BackgroundThis study assessed the prevalence of traumatic dental injuries (TDI) and its association with sociodemographic and physical characteristics in the anterior permanent teeth of 12-year-old schoolchildren at the city of Brasília – DF, Brazil.MethodsA cross-sectional, population-based study was conducted on a sample of 1,389 boys and girls aged 12 years, enrolled in public and private fundamental schools at the Administrative Region (RA) of Brasília, Brazil, from October 2011 to September 2012. The demographic details were achieved by a structured questionnaire. The study recorded the type of damage, the size of incisal overjet, and whether lip coverage was inadequate. Sociodemographic data included sex, income and educational level of the parents or caretakers.ResultsA total of 1118 schoolchildren were examined, yielding a response rate of 80.48%. The prevalence of TDI was 14.63% in public schools and 23.40% in private schools. The students did not differ according to sex, income and educational level of the parents or caretakers concerning the occurrence of traumas in permanent anterior teeth. Increased overjet and inadequate lip coverage were found to be important contributing factors for TDIs.ConclusionIn conclusion, this study showed an expressive prevalence of TDI in 12-year-old in schoolchildren at Brasília DF, Brazil. Sex and educational level of the parents were not associated with trauma. The increased overjet and inadequate lip coverage were significantly associated with dental trauma.

Summary
This study assessed the prevalence of traumatic dental injuries (TDI) and its association with sociodemographic and physical characteristics in the anterior permanent teeth of 12-year-old schoolchildren at the city of Brasília – DF, Brazil. Traumatic dental injuries (TDI) have been extensively studied over the last few decades. They result in tooth fracture, displacement or loss, causing negative functional, esthetic and psychological effects to the individuals (children, adolescents and adults) [1,2,3]. Glendor [20] conducted a literature review on the etiology and reported risk factors for traumatic dental injuries and concluded that the number of causes of TDIs have alarmingly increased over the last decades. The author suggested that this phenomenon may be associated to the increased interest on the causes and evidences the complex etiology of TDIs. The investigator concluded that risk factors as overjet and inadequate lip coverage contribute to increase the TDIs, and the complex interaction between the oral status of the patient, design of public parks and school playgrounds and human behavior. The question is to what extent these factors, together or separately, influence the risk of TDI
