Epidemiology of dental caries: When structure and context matter

Abstract

The widespread expansion of the sugar market drove dental caries prevalence to high levels in several regions of the world. On the other hand, the dissemination of fluoride use is one of the reasons for caries decline at the end of the 20th century. However, caries remains one of the most prevalent non-communicable chronic diseases in human beings, and an important cause of pain and dental loss, which lead to school and work absenteeism affecting individuals' daily activities and emotional stability. The decline in caries has important implications for research, human resources and oral healthcare. The aim of this study was to summarize the changes in dental caries occurrence in the population, and bring to light the latest research on the role of non-biological determinants in caries distribution.
