Children were randomly selected from the study list of «Obesity in Tamaulipas’ under 30 population, effects on health, treatment and prevention» conducted in this hospital. All subjects provided written consent, thereafter, oral examination was performed in order to determine, according to WHO parameters, presence of dental caries, gingivitis and malocclusions.

Caries prevalence was 87%, gingivitis was present in 63% of all cases, and malocclusions were present in 33% of patients. Ceo-d index was 2.97 and CPO-D was 3.08. Multivariate analysis revealed relationship between the ceo-d index with age (p = 0.00), with overweigh and obesity and with malocclusions (p = 0.016) as well as relationship between age and gingivitis (p = 0.01) and age and malocclusion (p = 0.042). Conclusions: Malocclusion and caries prevalence resulted similar to that observed in other studies performed in Mexico. Nevertheless, gingivitis was more frequent.
