Combined antiretroviral therapy (cART) vs No antiretroviral medication (treatment-naive)

Oral candidiasis prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

cART was associated with a significantly lower prevalence of oral candidiasis in CLWH (very low certainty).

Monotherapy or dual antiretroviral therapy vs No antiretroviral medication (treatment-naive)

Oral candidiasis prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

Oral candidiasis prevalence did not differ significantly between treatment-naive CLWH and those on monotherapy or dual therapy (very low certainty).

Food and nonalcoholic beverage marketing (exposure) vs No, less, or less powerful food marketing

Purchase requests · Children and adolescents (general population, aged under 20 years)

Nonrandomized evidence on purchase requests is very uncertain (very low certainty).

Prior SDF application without 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 without a rinsing step does not affect glass-ionomer cement bond strength to sound dentin (MD 0.26 MPa, 95% CI -0.20 to 0.73; ungraded).

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

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

No eligible studies compared dental development and maturation between different ART regimens.

Food and nonalcoholic beverage marketing (exposure) vs No, less, or less powerful food marketing

Food choice · Children and adolescents (general population, aged under 20 years)

Food marketing probably increases children's choice of the marketed food (OR, 1.97; moderate certainty, RCTs).

Antiretroviral therapy (any, including cART) vs No antiretroviral medication (treatment-naive)

Angular cheilitis prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

No significant difference in angular cheilitis between CLWH with and without ART (very low certainty).

Fluoride-free nano-/micro-hydroxyapatite (nHA) dentifrice vs Control (regular fluoride) dentifrice

Caries lesion initiation/progression (ICDAS score, laser fluorescence/DIAGNOdent, photographic pixels, enamel acid resistance) · Patients (children and adults, age 3-40 years) with initial enamel caries lesions (non-orthodontic and orthodontic)

No meta-analysis was possible for the 5 in vivo RCTs (high heterogeneity); narratively nHA showed generally no significant difference versus fluoridated dentifrice, and the evidence was not graded (ungraded).

  • Efficacy of nano-hydroxyapatite on caries prevention-a systematic review and meta-analysis. 2022 All outcomes
    Median follow-up 6 months (range 6-12 months) · In vivo (clinical); non-orthodontic and orthodontic patients
    No meta-analysis was performed for the in vivo studies owing to high heterogeneity (population, control group, outcomes, follow-up periods, risk of bias) and differing statistical designs (e.g., non-inferiority);…

Antiretroviral therapy (any, including cART) vs No antiretroviral medication (treatment-naive)

Ulcerative stomatitis prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

Ulcerative stomatitis was significantly more prevalent in treatment-naive CLWH than in those on ART (very low certainty).

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

Acute necrotizing ulcerative gingivitis/periodontitis (WHO clinical stage 3) · Children or adolescents

No eligible studies reported acute necrotizing ulcerative gingivitis/periodontitis.

Baby-led weaning (BLW) vs Other models of complementary feeding

Overweight/obesity risk · Healthy children aged 6–24 months in Western industrialized countries

BLW was associated with lower overweight/obesity risk in observational studies, but the certainty was very low.

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

Chronic herpes simplex infection (WHO clinical stage 4) · Children or adolescents

No eligible studies reported chronic herpes simplex infection.

Isolated cleft palate (CP) or other specific cleft type vs Cleft lip and palate (CLP) or other cleft type

Caries experience by cleft type · Children in the primary dentition with cleft lip and/or palate (CL/P)

Whether cleft type is associated with caries experience could not be determined; the planned CP-versus-CL/P subgroup analysis was not possible owing to sparse isolated-CP data (5 studies described narratively; ungraded).

  • Caries in children with and without orofacial clefting: A systematic review and meta-analysis. 2022 All outcomes
    Children with CL/P and comparable non-CL/P children across 12 countries (India, Brazil, China, Sweden, UK, USA, Germany, Greece, Ireland, Netherlands, Jordan, Thailand); studies published 1989-2021
    Five studies investigated caries experience by cleft type (Howe 2017; Kirchberg 2014; Mutarai 2008; Sunderji 2017; Zhu 2010). A subgroup analysis comparing CP and CL/P as different entities was not possible due to the…

Primary dentition DMFT score over 13 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 over 13 is associated with about 15 times higher risk of caries in permanent teeth (single study; not GRADE-rated).

Poor (inadequate) oral hygiene (prevalence) · Children or adolescents

No significant difference in oral hygiene between CLWH on ART and healthy controls (OR 1.23, 95% CI 0.73 to 2.07; single study).

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

Immediate bond strength (MPa) · Dental adhesives bonded to sound dentin (in vitro)

A rinsing step after SDF eliminates the negative effect on adhesive bond strength to sound dentin (MD 7.11 MPa, 95% CI -0.57 to 14.79, non-significant; ungraded).
