Between 1991 and 1993, the data of 479 clinical records were compiled about caries in the permanent teeth of subjects of both sexes, whose dental examinations were carried out in a private dental clinic in the city of Salamanca and who were distributed by age into groups of 16–65, 26–55 and 36–15 years. Using the method known as system of expansion-contraction, we showed that caries has a non-linear dynamic, whose evolution in time is difficult to predict and which has a fractal geometry. This study shows the fractal geometry of caries and to achieve this uses a little-known method which will be of great use in future research.
