Prevalence, causes and correlates of traumatic dental injuries among 13‐year‐olds in Brazil

Abstract

A cross-sectional survey was carried out. This involved 652 out of a total of 764 (85%) 13-year-old adolescents enrolled in private and public schools located in urban areas in Cianorte, Brazil. They were interviewed and examined for traumatic dental injuries by one trained examiner (B.N.) using validated criteria. Sociodemographic data included sex, family structure (nuclear families, single parents and step-parents) and socio-economic indicators. Anthropometric measures included height and weight. The body mass index (BMI) was calculated (mean=20.1; SD=3.7). Those who had BMI scores equal or above the 85% percentile were considered overweight (BMI >23). The prevalence of traumatic injuries to the permanent incisors was 20.4%. The most common reported cause of injuries to the permanent incisors was falls (24.1%) followed by collisions with people or inanimate objects (15%), traffic accidents (10.5%), misuse of the teeth (6%), sports (2.3%) and violence (1.5%). Unknown causes accounted for 40.6%. Children from non-nuclear families, overweight children and boys were 2.18, 1.93 and 2.19 times respectively more likely to have dental injuries than children from nuclear families, non-overweight children and girls (P<0.01) after adjusting for family structure, BMI, sex, family income and level of education of the parents. The relationship between dental injuries and socioeconomic indicators was not statistically significant. In conclusion, being from a non-nuclear family, overweight and a boy increased the risk of having traumatic dental injury, but the relationship with socio-economic indicators was not statistically significant.

Traumatic Dental Injuries and Its Relation to Overweight among Indian School Children Living in an Urban Area

“…This study revealed that OW children were 3.85 times more prone to TDI than NW children. Further, the relationship between the presence of dental trauma and OW (≥85 th percentile BMI) was statistically significant in our study which is in agreement with the findings in the literature [8,9,22]. On the contrary, few other studies did not detect any statistically significant relation between TDI and OW [20,23,24].…”

“…The present study evaluated overweight using BMI which is similar to that used in other studies [8,22]. However, an earlier study by Soriano et al, [9] reporting obesity as risk factor to trauma used different diagnostic criteria (the NCHS reference tables) for evaluating obesity.…”

“…Recent estimates of the prevalence of these injuries to anterior teeth in children shows wide variation [2][3][4]. Various risk factors to TDI suggested in the literature include excessive overjet, [4][5][6] inadequate lip coverage, [5,6] high socioeconomic status, [7] and childhood obesity [8,9].…”

“…Em relação ao sexo, a maioria dos estudos mostrou que as crianças do sexo masculino sofrem, significativamente, mais injúrias traumáticas nos dentes do que as crianças do sexo feminino 3,7,10,24,25,27,29,31,32,34,39,45,46,50,51,[53][54][55][56][57][58][59][60][61] .…”

Estudo do Traumatismo Dentário em Escolares do Município de João Pessoa, PB, Brasil

“…Levantamentos realizados no Brasil têm destacado a grande prevalência de traumatismos dentários na dentição decídua e mista, variando de 10,4% a 58%, dependendo da faixa etária e do local em que são coletados os dados [2][3][4][5][6][7][8][9] . Quando o estudo é realizado em ambiente hospitalar, os tipos de traumatismo mais registrados são os deslocamentos (luxações), enquanto que em escolas, domicílio ou consultórios são observados traumatismos de menor magnitude 10 .…”
