Xylitol lozenges (4.7 g/day) vs no treatment

Chlorhexidine varnish (10%) vs placebo or no treatment

Elevated mutans streptococci levels (>=4 with caries screen; high vs low) · Children and adolescents below 18 years at study start (included studies: children from birth to 15 years), with mixed, permanent or…

It is very uncertain whether chlorhexidine varnish (10%) changes elevated mutans streptococci levels (>=4 with caries screen; high vs… compared with placebo or no treatment (very low certainty).

Dental caries assessment (WHO/clinical diagnostic criteria; caries = DMFT>0) vs Caries-free status

CA VI activity · Children (age about 2-9 years) across the 7 meta-analyzed activity samples; excludes Kivela 1999 adults (18-24 years), qualitative only…

Salivary/biofilm CA VI activity is significantly higher in individuals with dental caries than in caries-free individuals (SMD 0.894, 95% CI 0.386 to 1.392; not GRADE-rated).

HAART (highly active antiretroviral therapy, >=3 drugs) vs HIV-positive not receiving HAART (standard ART or HAART-naive)

Dental caries · Children and adolescents (<18 years) living with HIV (CLWH)

Among HIV+ children, HAART versus no HAART showed no significant difference in the odds of dental caries by DMFT in cross-sectional studies (OR 1.29, 95% CI 0.59 to 2.84; ungraded).

HAART (highly active antiretroviral therapy, >=3 drugs) vs HIV-positive not receiving HAART (standard ART or HAART-naive)

Dental caries in permanent teeth · Children and adolescents (<18 years) living with HIV (CLWH)

Among HIV+ children, HAART was associated with a significantly higher DMFT index than no HAART in case-control studies (MD 2.02, 95% CI 1.24 to 2.80; ungraded).
