ABSTRACT

The aim of this study was to evaluate the association betweenoverweight/obesity and the occurrence of traumatic dentalinjury among schoolchildren aged 7 to 14 years. A cross-sectionalstudy was carried out involving 590 students at publicschools in the city of Campina Grande, Brazil. The classificationproposed by O’Brien (1994) was used for the diagnosis oftraumatic dental injury. Overweight/obesity was determinedbased on the body mass index. Clinical examinations were performedby two examiners who had undergone a calibrationexercise (Kappa statistics of 0.87 and 0.90 for intra-examinerand inter-examiner, respectively). Data analysis involved thechi-square test and Fisher’s exact test with a 5% level of significance.Traumatic dental injury was less prevalent among theschoolchildren with overweight/obesity than those without thiscondition (8.7% and 13.3%, respectively). When the sample wasstratified by gender and age, traumatic dental injury was alsomore prevalent among schoolchildren without overweight/obesity.When the sample was stratified based on ethnicity,prevalence rates were similar between those with and withoutoverweight/obesity. In the overall sample, no significant associationwas found between overweight/obesity and traumaticdental injury (p = 0.253). Overweight/obesity among schoolchildrenaged 7 to 14 years was not associated with traumaticdental injury in this study. The analysis of physical activity maybe important to gain a better understanding of this finding...


O objetivo do presente estudo foi avaliar a associação entre osobrepeso/obesidade e a ocorrência do trauma dentário entreescolares de 7 a 14 anos de idade. Caracterizou-se como um estudotransversal realizado com 590 escolares de escolas públicasde Campina Grande, Brasil. Utilizou-se como critério de diagnósticopara traumatismo dentário a classificação proposta porO’Brien (1994) e para sobrepeso/obesidade o índice IMC. Osexames clínicos foram feitos por dois examinadores previamentecalibrados (Kappa intra e inter de 0,87 e 0,90, respectivamente).Os testes estatísticos utilizados foram Qui-quadrado e exato deFisher (significância de 5%). Os indivíduos sem sobrepeso/obesidadeapresentaram mais lesões de trauma dentário que aquelescom sobrepeso/obesidade (13,3% vs 8,7%). Quando estratificadaa amostra em relação ao sexo, idade e grupo étnico, otraumatismo dentário foi mais prevalente entre crianças/adolescentessem sobrepeso/obesidade, com exceção do grupo étnico,que apresentaram prevalências similares. No grupo total não foiobservada associação entre sobrepeso/obesidade e trauma dentário(p=0,253). A presença de sobrepeso/obesidade em escolaresde 7 a 14 anos não foi associada ao traumatismo dentário. Aanálise da atividade física pode ser um fator importante paramelhor elucidar a temática...
