Cerebral palsy (oral health status) vs Healthy controls

Oral health status (caries, gingivitis, calculus, treatment indices) · Children with cerebral palsy in Dubai

One study found children with cerebral palsy had caries and gingivitis similar to matched controls but more calculus and anomalies, with lower restorative care despite greater need (narrative synthesis; not GRADE-rated).

Systemic sclerosis (SSc / scleroderma) vs SSc-free individuals (controls)

Maximal mouth opening (interincisal distance) · Adults (general and hospital populations assessed in case-control studies)

Systemic sclerosis patients have significantly reduced mouth opening compared with controls (SMD -1.06); certainty ungraded.

Fluorescence-based devices vs Dental imaging (analog or digital radiographs)

Difference in specificity · Asymptomatic children or adults suspected of enamel caries (clinical studies); extracted teeth (in vitro studies)

Fluorescence and imaging had similar specificity in the fully within-person analysis.

Coating material (bonding material or sealant) WITH fluoride release vs Coating material WITHOUT fluoride release

White spot lesions assessed by laser fluorescence (DIAGNOdent) · Patients of any age (11-40 years) receiving comprehensive/fixed orthodontic treatment with fixed appliances

White spot lesions were also measured by laser fluorescence in 3 fluoride-vs-non-fluoride studies, but no meta-analysis was possible due to incompatible reporting.

Frequent carbohydrate / sugary food intake vs Infrequent carbohydrate intake

Dental caries · Individuals in East Africa assessed for dental caries

Frequent carbohydrate intake was associated with significantly higher odds of dental caries (OR 1.575, 95% CI 1.13 to 3.051); certainty not graded.

Systemic sclerosis (SSc / scleroderma) vs SSc-free individuals (controls)

Number of teeth · Adults (general and hospital populations assessed in case-control studies)

No statistically significant difference in number of teeth between SSc patients and controls (SMD -0.95, CI includes 0); certainty ungraded.

Autism spectrum disorder vs Healthy school-aged children (for some measures)

Oral health status and oral-care challenges · Children with autism spectrum disorder in Dubai

Two studies found high caries (77%) and gingivitis and considerable oral-care challenges among children with autism spectrum disorder, with low restorative indices (narrative synthesis; not GRADE-rated).

Dental caries assessment (WHO/clinical diagnostic criteria; caries = DMFT>0) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Dental caries prevalence · Healthy children and adolescents in the United Arab Emirates

Dental caries is highly prevalent among children and adolescents in the UAE, ranging from 22% to 99.4% across cross-sectional studies (narrative synthesis; not GRADE-rated).
