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).

Periodontitis vs No periodontitis (periodontal health or gingivitis)

Lacunar stroke · adults

Individuals with periodontitis had about five times higher odds of lacunar stroke than those without periodontitis (pooled OR 5.16); ungraded cross-sectional evidence, with the caution that the three studies came from one research team.

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).

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

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).

Intra-examiner reliability · Children and adults with primary or permanent dentition undergoing dental caries assessment

Intra-examiner reliability ranged from kappa 0.52 to 1.00 across 6 studies; certainty not graded.

Not applicable (single-group prevalence) vs Not applicable (single-group prevalence)

Periodontal disease prevalence · Children (<18 years) with intellectual and developmental disabilities (IDD) in India

In the single study reporting it, periodontal disease prevalence was 54.2% (single study; ungraded).

Milk-based probiotic vs placebo or control

Plaque index (PI) / oral hygiene · Children and/or adolescents (<18 years) without background systemic disease

In a subgroup analysis, milk-based probiotics reduced the bacterial plaque index more than other presentations (MD -0.10, 95%CI -0.20 to -0.00; p-interaction=0.01); not GRADE-rated.

Slum residence vs Non-slum urban setting

Dental caries · Adult residents of slums and non-slum urban settings of LMICs

Slum residents had non-significantly higher odds of caries than non-slum residents (OR 1.21, 95% CI 0.94-1.56; single study); ungraded.
