Studies on the relationship between obesity and traumatic dental injuries (TDIs)

Author	Country	N	Ages in years	Conclusions
Petti et al. [3]	Italy	938	6-11	- Obesity significantly increased the risk of TDIs. One-third of obese children was affected vs. only one fifth of other subjects.
Nicolau et al. [4]	Brazil	652	13	- Being from a non-nuclear family, overweight and a boy increased the risk of having a TDI.
				- Overweight children were 1.93 times more likely to have dental injuries than those who were not overweight
Granville-Garcia et al. [5]	Brazil	2651	1-5	-Overweight/obese children had 2.5 times more trauma than non-overweight/obese ones
Soriano et al. [6]	Brazil	1046	12	- Obese subjects sustained more TDIs than non-obese subjects. However, it was concluded that the presence of obesity was not associated to TDIs in adolescents from Recife, Brazil.
Ărtun and Al-Azemi [7]	Kuwait	1583	13-14	- No difference was detected in TDIs rate among the subjects in the three BMI categories
Damé-Teixeira et al. [8]	Brazil	1528	12	- No significant association was found between BMI and obesity.
