[Inequalities in the distribution of dental caries in Brazil: a bioethical approach].

The scope of this paper was to analyze the problem of dental caries as a public health issue of epidemiological relevance. It is a case study based on documentary analysis of national epidemiological surveys on oral health in the years 1986, 2003 and 2010, with the Bioethics of Protection as an analytical support. The surveys revealed inequalities between population groups; and such inequalities were analyzed with respect to the reduction of the disease in the younger population, access to oral health care, and tooth loss, which is the worst outcome for tooth decay. The good results presented in the surveys have not reached the whole population; data have shown inequalities regarding family income and Brazilian region. It was also found that from 2003 government interventions in protective actions such as the adoption of criteria of equity in the allocation of health resources and inclusion of vulnerable population have contributed to a reduction in caries. Nevertheless, it is considered necessary update oral health care models by using Epidemiology as a structuring tool, and an interface with socially responsible protective bioethics, since regional differences continued to be marked in the analysis.
