Etiology and environment of dental injuries in 12‐ to 14‐year‐old Ontario schoolchildren

Abstract

This study reports on the etiology and environment where dental injuries occurred and assesses the relationship between dental trauma, socio-economic status and dental caries experience. A population-based, matched case-comparison study was undertaken in 30 schools in two Ontario communities. Dental hygienists calibrated in the use of the Dental Trauma Index (DTI) screened 2422 children aged 12 and 14 years using DTI and Decayed, Missing and Filled Teeth indices. Cases (n = 135) were children with evidence of dental injury. Controls (n = 135) were children randomly selected after screening and matched with cases according to age and gender. Questionnaires were mailed to parents and children. Prevalence of dental injury was 11.4%, mostly minor injuries 63.7% (enamel fracture not involving dentin), affecting one upper central incisor (70.4%). The mean age at the time of dental injuries was 9.5 years (SD = 1.49; range: 6-13 years). Dental trauma most often occurred among boys at school because of falls or while playing sports. The relationship between dental injuries and the socio-economic indicators chosen was not statistically significant. However, a statistically significant direct relationship (P < 0.001) was shown between increased caries experience and dental injuries. This should focus attention on possible common-risk factors such as health-related behavioral problems that may affect both dental disease and dental injuries.

Socioeconomic and clinical factors associated with traumatic dental injuries in Brazilian preschool children

“…However, most studies of TDI have reported its prevalence in permanent teeth. [1][2][3][4] Although several recent studies have assessed the prevalence of TDI in primary teeth and its associations with socioeconomic indicators, the results have been inconsistent and conflicting. [5][6][7][8][9][10] In Brazil, the TDI prevalence in primary teeth ranges from 9.4% to 41.6%, [5][6] and there is evidence that TDI prevalence in deciduous teeth is increasing.…”

Estudo transversal em escolares de 12 anos de idade sobre a necessidade de tratamento, etiologia e ocorrência de traumatismo dentário em Montes Claros, brasil.

“…Outros fatores etiológicos relatados O resultado da maioria dos estudos apontou o gênero masculino como o mais acometido por traumatismo dentário 3,7,9-11,13-15,23-24 e a principal etiologia a queda [13][14][15][16][17] . Associação estatisticamente significante entre gênero masculino e queda foi reportada na Nigéria 13 , no Irã 15 e no Canadá 21 . Estudos mostraram que os meninos estão mais ligados a atividades esportivas ou brincadeiras em locais abertos, sendo por este motivo mais exposto a acidentes intencionais ou não, podendo provocar traumatismo dentário 20,23 .…”

“…As causas do traumatismo dentário são amplamente conhecidas, sendo as principais quedas, colisões contra objetos ou pessoas, acidentes automobilísticos, práticas esportivas e violência 3,5,8,[11][12][13][14][15][16][17][18][19][20][21] . A maioria dos estudos de frequência que avaliaram as causas do traumatismo dentário apontou a queda como o principal fator etiológico [13][14][15][16][17] .…”

“…TARTIŞMA TDY yaşamın her döneminde meydana gelebildiği gibi çocukların bu yaralanmalara daha sık maruz kaldığı bilinmektedir. 13,14 İlkokul çağındaki çocukların yaşları ve okullarda geçirdikleri uzun süreler nedeniyle travma sonucu meydana gelen diş yaralanmalarının büyük bir kısmı okullarda gerçekleşmektedir. 5 Kron kırıklarında kırık parçanın bulunması veya avülsiyona uğrayan dişlerin uygun ortamda taşınması gibi travmaya uğrayan bir dişe yapılacak doğru ve hızlı bir acil müdahale dişin prognozunu önemli ölçüde etkilemektedir.…”
