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

Fluoride mouthrinse (0.05-0.32% sodium fluoride or amine fluoride) added to daily fluoride toothpaste vs Control: fluoride toothpaste alone, placebo mouthrinse + toothpaste, or non-fluoride (chlorhexidine) mouthrinse + toothpaste

Incidence of initial caries around brackets, aesthetic-zone teeth only · Orthodontic patients (any age) undergoing orthodontic treatment (mostly fixed appliances)

When only aesthetic-zone teeth (incisors and canines) were considered, two studies reported a significant reduction in initial caries incidence favoring fluoride mouthrinse (ungraded, narrative; no pooled estimate).

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

There is no significant difference in salivary alpha-amylase between anorexia nervosa patients and healthy controls (MD 6.32 U/l, 95% CI -6.14 to 18.79; low certainty).

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

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

Anorexia nervosa probably reduces unstimulated salivary flow rate versus healthy controls (MD -0.27 ml/min, 95% CI -0.31 to -0.24; moderate certainty).

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).

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

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).

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

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).

Fluoride mouthrinse (0.05-0.32% sodium fluoride or amine fluoride) added to daily fluoride toothpaste vs Control: fluoride toothpaste alone, placebo mouthrinse + toothpaste, or non-fluoride (chlorhexidine) mouthrinse + toothpaste

Incidence of initial enamel caries / white spot lesions adjacent to bracket base (subject level, dichotomized) · Orthodontic patients (any age) undergoing orthodontic treatment (mostly fixed appliances)

Adding a fluoride mouthrinse to daily fluoride toothpaste produced a small reduction in the incidence of initial caries/white spot lesions adjacent to brackets (pooled risk difference -0.07, 95% CI -0.14 to -0.01; 5 studies, 491 subjects), but the authors judged the overall evidence inconclusive (ungraded).

Fluoride mouthrinse (0.05-0.32% sodium fluoride or amine fluoride) added to daily fluoride toothpaste vs Control: fluoride toothpaste alone, placebo mouthrinse + toothpaste, or non-fluoride (chlorhexidine) mouthrinse + toothpaste

Side effects or other adverse events · Orthodontic patients (any age) undergoing orthodontic treatment (mostly fixed appliances)

No adverse effects were reported in any of the seven included studies (ungraded).
