We propose to describe the prevalence of caries and periodontal disease in dental students and to determinate the association with demographic variables. A crosssectional descriptive study. The sample was selected stratified probability style and corresponded to 234 students in the University of Cartagena Dentistry. The clinical measurements were made through the levels COP, ICDAS II, INTCP, simplified oral hygiene Green and Vermillion. In addition, measured the age, sex and socioeconomic stratum. We performed univariate analysis (frequency distributions and averages) and bivariate analysis using the X test statistic for statistical significance. The overall prevalence of caries experience in the subjects involved was 55.9 % (95 % CI 49-62), being higher initial injuries. On the COP-S, the average was 10.1 (SD= 5.5), even observe higher for the group of students over 26 years (p= 0.05) and students who belong to layer one (low) (p= 0.03). Students presented a high burden of oral disease, but according to the severity of most events, these are early stage, allowing prompt diagnosis to prevent progression of these patology.
