Relationship between traumatic dental injuries and obesity in Brazilian schoolchildren

Abstract

The aim of this study was to investigate if obesity is associated to the occurrence of dental trauma in the permanent anterior teeth of adolescents from Recife, Brazil. It included a random sample of 1046 boys and girls aged 12 years attending both public and private schools. The sample size was calculated using a 95% confidence interval level; a statistical significance of 5%; and an odds ratio of 1.55. The sample selection was carried out in two stages: first, schools were selected by simple sampling, and then children were chosen using a proportionality coefficient. Data were collected through clinical examinations and interviews, after examiner calibration. Dental trauma was classified according to ANDREASEN; ANDREASEN criteria. Obesity was considered according to National Center of Health Statistics - NCHS (USA) procedures for the assessment of nutritional status. Subjects were considered as non-obese when the observed percentile was < or = 97, while obese adolescent presented percentiles >97. Data were summarized and analyzed using the statistical software SPSS. The prevalence of traumatic injuries was higher among obese boys than obese girls (17.2% and 16.2%, respectively), but there were no statistically significant differences between traumatic dental injuries and obesity (P > 0.05). It was concluded that the presence of obesity was not associated to traumatic dental injuries in adolescents from Recife, Brazil.

Traumatic dental injuries among 12-year-old Jordanian schoolchildren: an investigation on obesity and other risk factors

“…This study did not demonstrate a significant association between TDIs to permanent anterior teeth and obesity among 12-year-old schoolchildren in Jordan (P >0.05). This corroborates with the findings of Soriano et al [6], Ărtun and Al-Azemi [7], and Damé-Teixeira et al [8]. However; other authors supported the opposite.…”

“…Nevertheless, the possible relationship between obesity and TDIs is still unclear. While two studies considered obesity a risk factor for TDIs [3,4], other studies showed no statistically significant relationship [6-8]. In Jordan, few epidemiological studies are available on TDIs to anterior permanent teeth among schoolchildren [9-11], but none of them has explored the relationship between TDIs and obesity.…”

Dental trauma: prevalence and risk factors in schoolchildren

“…A sex-stratified analysis showed that the prevalence of dental trauma was greater in overweight/obese boys than in normal-weight boys. Petti et al (12) and Nicolau et al (26) found that childhood obesity significantly increased the risk of traumatic injury, but subsequent studies showed no association between dental trauma and height/ weight proportions (16,25,27,28). The association of obesity with dental trauma may be explained by obese children's reduced agility and greater likelihood of accidents, whereas normal weight may improve motor skills, thereby reducing the risk of accidental falls or incidents during interaction and play with family and friends.…”

Epidemiologia do Traumatismo Dentário em Crianças: A Produção Científica Brasileira

“…Foi realizada uma revisão da literatura sobre dados epidemiológicos de TD no Brasil 11,12 , prática esportiva 13,14 e, ainda, conhecimento de profissionais, educadores e cirurgiões-dentistas frente ao TD 15,19 .…”

“…Pouquíssimos estudos avaliaram a associação entre obesidade e a prevalência de TD, e seus resultados apresentaram-se não concordantes 11,12 . Neste estudo, também se observou que, com relação ao conhecimento sobre o atendimento do TD, melhor capacitação deve ser oferecida tanto para os cirurgiões dentistas quanto para outros profissionais, como cuidadores e educadores, frequentemente presentes no momento do traumatismo dentário [15][16][17][18][19] .…”
