Oral health education only (verbal, written, or audio-visual education) delivered by non-dental health workers vs control (no intervention/usual care/isotonic exercise)

Caries experience at the surface level (dmfs/defs) · Children (mean age newborn to ~5.2 years) and their parents/carers

Oral-health-education-only interventions did not show a statistically significant effect on surface-level caries (dmfs SMD -0.20, 95% CI -0.43 to 0.03; 2 studies; not GRADE-rated).

Combined antiretroviral therapy (cART) vs Monotherapy or dual antiretroviral therapy

No eligible studies compared angular cheilitis between different ART regimens.

Caries in first and second primary molars vs Reference (other primary tooth locations / caries-free)

Caries development in permanent teeth · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)

Caries in the first and second primary molars is the strongest tooth-specific predictor of caries in permanent teeth (RR 3.4; single study; not GRADE-rated).

Prior SDF application with a rinsing step vs No prior SDF application (untreated dentin control)

Immediate bond strength (MPa) · Glass-ionomer cement bonded to sound dentin (in vitro)

SDF pretreatment with a rinsing step does not affect glass-ionomer cement bond strength to sound dentin (MD -1.11 MPa, 95% CI -3.47 to 1.25; ungraded).

Atraumatic restorative treatment plus fluoride varnish vs Silver diamine fluoride plus fluoride varnish

Oral health-related quality of life · Children with dental caries

The direct estimate found no statistically significant difference in oral health-related quality of life between atraumatic restorative treatment plus fluoride varnish and silver diamine fluoride plus fluoride varnish.

SDF applied biannually (every 6 months) vs Other non/minimally-invasive treatment (ART or 5% NaF varnish)

Caries arrest · Children (age 1-10 years) with active cavitated dentin caries lesions in primary molars

Biannual SDF application significantly arrested caries (pooled ES 0.39, 95% CI 0.19-0.60; ungraded).

Silver diamine fluoride (SDF) vs Atraumatic restorative treatment (ART)

Oral health-related quality of life · Children with dental caries

SDF did not significantly differ from atraumatic restorative treatment for oral health-related quality of life (MD 0.02, 95% CI -0.32 to 0.36; ungraded).

Primary dentition DMFT score 1-3 vs No caries in primary teeth (DMFT = 0)

Caries prevalence in permanent dentition · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)

A primary-dentition DMFT of 1-3 is associated with 1.5 times higher risk of caries in permanent teeth (single study; not GRADE-rated).

Combined antiretroviral therapy (cART) vs Monotherapy or dual antiretroviral therapy

Recurrent oral ulceration prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

No significant difference in recurrent oral ulceration between ART regimens (very low certainty).

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

Dental caries prevalence · Children or adolescents

In permanent dentition, CLWH on ART had higher caries prevalence than healthy controls (OR 2.49, 95% CI 1.86 to 3.32; single study).

Resin infiltration vs Baseline before resin infiltration

Color change · Patients with post-orthodontic white spot lesions and permanent dentition

Eckstein (2015) reported a statistically significant color-change effect.

CD4+ T-cell count below 250 cells/mm3 vs CD4+ T-cell count >=250 cells/mm3

HIV-related oral lesions · Children and adolescents living with HIV on ART/HAART

Lower CD4+ counts (<250 cells/mm3) were associated with roughly twice the odds of HIV-related oral lesions in two studies (not pooled).

  • Oral Health Status of Children and Adolescents Living with HIV Undergoing Antiretroviral Therapy: A Systematic Review… 2022 All outcomes
    Cross-sectional (case-control; single time point) · HIV pediatric/ART clinics, AIDS centers, and hospitals in Brazil, India, Saudi Arabia, and West Africa (Cote d'Ivoire, Mali, Senegal) · CD4+ T-cell count <250 cells/mm3 vs higher
    CLWH with CD4+ <250 cells/mm3 were about twice as likely to have HIV-related oral lesions: Baghirath 2013 OR 1.916 (95% CI 0.613 to 2.513), p=0.001; Divakar 2015 OR 1.999 (95% CI 0.129 to 3.688), p=0.001. Not pooled.

Responsive complementary feeding (RCF) / other caregivers' feeding practices vs Other models of complementary feeding (traditional/non-responsive CF)

Type 2 diabetes (later in life) · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

No eligible studies examined the influence of complementary feeding practices on later type 2 diabetes; this is an evidence gap.

Dental caries vs Caries-free status

Alpha diversity (Observed, Chao1, Shannon, and Simpson) · Participants in oral 16S rRNA caries microbiome studies

Across the combined sample set, alpha-diversity metrics were significantly higher in caries than in health, but no pooled effect estimate was reported.

Comprehensive oral health intervention (oral health education plus additional support: motivational interviewing, toothbrush/toothpaste provision, community engagement, and/or fluoride varnish/sealant application) delivered by non-dental health workers vs control (no intervention/usual care/isotonic exercise)

Caries experience at the surface level (dmfs/defs) · Children (mean age newborn to ~5.2 years) and their parents/carers

Comprehensive interventions produced a small, statistically significant reduction in surface-level caries (dmfs SMD -0.14, 95% CI -0.26 to -0.02; 10 studies; not GRADE-rated).
