Title Eating Disorders Negatively Impact Oral Health
Clinical Question Do eating disorders have a negative impact on oral health?
Clinical Bottom Line Eating disorders negatively impact oral health. This is supported by a meta-analysis of studies included in a systematic review. The results show a significant increase in dental erosion and DMFT/S and significantly reduced salivary flow compared to that of the control group.

Key resultsPatients with self-induced vomiting had significantly higher odds of dental erosion (OR = 7.32) compared to that of the control patients. Patients with an eating disorder also had significantly higher decayed, missing, and filled teeth or surfaces (DMFT/S) (mean difference = 3.07, 95% CI 0.66-5.48) and reduced salivary flow (OR=2.24, 95% CI 1.44-3.51).

Comments on
The Evidence
Validity: A systematic search of the literature was performed using using Medline, PsycINFO, EMBASE, and article bibliographies. Of the studies located through the search, “ten studies had sufficient data for a random effects meta-analysis.” The authors state, "All but two of the results had an I2 [I-squared] estimate of 50% or more, indicating possible heterogeneity." Furthermore, regarding the included studies, the authors state, "Study quality was not optimal." Taken together, this indicates that one should view the conclusions of the systematic review and meta-analysis with some skepticism. Perspective: This evidence suggests that eating disorders can negatively affect the oral health of a patient. The clinician may be able to identify the signs of a possible eating disorder and intervene by providing the patients with information on the effects of self-induced vomiting on the oral cavity.
Applicability These results suggest that a patient may have an eating disorder when dental erosion, reduced salivary flow, higher DMFT/S are present. It should be noted that other factors can cause similar symptoms, like acid reflux or medications.
