Non-syndromic cleft lip and palate (CLP) status and its oral microbiota (exposure/grouping) vs Children and adolescents aged 0-18 years without CLP (controls)

Dental caries · Children and adolescents aged 0-18 years with non-syndromic cleft lip and palate (CLP)

Pooling 3 studies, children/adolescents with CLP were about 2.03 times more likely to have dental caries than non-CLP controls (p<0.005; low heterogeneity), though most included studies were at high risk of bias; the evidence is ungraded.

Teledentistry diagnosis using DSLR or smartphone extra-oral photographs vs Visual or clinical examination

Positive predictive value for dental caries diagnosis · Children and adults with primary or permanent dentition

Positive predictive values were reported in 10 of the 13 studies that reported sensitivity and specificity; no meta-analysis or GRADE rating was reported.

Down syndrome vs Individuals without Down syndrome (healthy controls: siblings, schoolchildren or others)

Mean DMFT (decayed, missing, filled permanent teeth) · Individuals of all ages

Individuals with Down syndrome had a lower mean DMFT in permanent teeth than controls (pooled SMD -0.18, 95% CI -0.35 to -0.02; 6 studies; I2=20%); certainty of evidence not graded.

Living with HIV and undergoing antiretroviral therapy (ART/HAART) vs HIV-negative individuals

Caries in primary teeth: dmft (3 years) · Children and adolescents (<18 years) living with HIV (CLWH)

In cross-sectional studies, the dmft (primary dentition) index did not differ significantly between HIV+ children on ART and HIV-negative peers (MD 0.92, 95% CI -0.09 to 1.93; very low certainty).

Living with HIV and undergoing antiretroviral therapy (ART/HAART) vs HIV-negative individuals

Dental caries severity (dmfs index, primary dentition) · Children and adolescents (<18 years) living with HIV (CLWH)

In case-control studies, HIV+ children on ART had a significantly higher dmfs index than HIV-negative peers (MD 5.15, 95% CI 2.20 to 8.11; not separately GRADE-rated).

School-based supervised toothbrushing (STB) vs no intervention

Dental caries increment, DMFT/dmft (whole-tooth level) · Children in school or kindergarten settings (aged 3-14 years)
