Anorexia nervosa (as exposure; diagnosed by DSM-III/III-R/IV/V) vs Healthy controls

Gingival (marginal) recession · Patients with anorexia nervosa aged >=12 years (mean age ~18.4; entirely female in reported data), general community-dwelling population

Gingival (marginal) recession was significantly higher in anorexia nervosa patients than controls in both reporting studies, but was not pooled or graded (ungraded).

Clinical dental/oral examination; case-control studies and controlled clinical trials in Europe (mainly Poland, Italy, France, Germany), Australia and the USA

Dental erosion · Patients with anorexia nervosa aged >=12 years (mean age ~18.4; entirely female in reported data), general community-dwelling population

Dental erosion was more prevalent in anorexia nervosa patients than controls (low erosive-wear severity), but was not pooled or graded (ungraded).

Significant prevalence of dental erosion in anorexic patients vs controls, though BEWE scores indicated low erosive-wear risk (Mascitti BEWE 5.2+/-4.5; Paszynska 16.2% at BEWE 3-8); not meta-analyzed

Plaque · Patients with anorexia nervosa aged >=12 years (mean age ~18.4; entirely female in reported data), general community-dwelling population

Anorexia nervosa patients tended to have higher plaque accumulation than healthy controls (significant in 2 of 3 studies), but results were not pooled or graded (ungraded).

Clinical dental/oral examination; case-control studies and controlled clinical trials in Europe (mainly Poland, Italy, France, Germany), Australia and the USA
In 2 of 3 studies anorexic patients had significantly higher plaque accumulation than controls (Pallier 78.8% vs 53.0%, p<0.01; Paszynska 43.8% vs 13.7%, p<0.001; Milosevic 84% vs 72%, NS); not meta-analyzed

Caries experience · Patients with anorexia nervosa aged >=12 years (mean age ~18.4; entirely female in reported data), general community-dwelling population

Anorexia nervosa is associated with significantly higher caries experience (DMFT) than healthy controls (MD 2.00 teeth, 95% CI 0.87 to 3.13; low certainty).
