This new systematic review explored the links between eating disorders and oral health, which were first noted in the 1970s. Ten studies were included in the review and higher odds of dental erosion were seen in those with eating disorders, with the odds being greater in those with self-induced vomiting.

Dental erosion is considered to be an increasing problem. However, clear information about the number of people affected is lacking. This review of 22 observational studies suggests that the worldwide prevalence is 30.4% (95%CI 23.8–37.0). However there is considerable heterogeneity between the studies in part related to the number of indices currently being used to measure tooth wear. So the estimate needs to be viewed with caution.
