HIV-infected children on antiretroviral therapy (HI) vs HIV-exposed but uninfected children (HEU)

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

HIV-infected children on ART had higher odds of dental caries than HEU children in a cohort study (OR 2.88, 95% CI 1.71 to 4.84; ungraded).

Ion-releasing restorations (IRR): RMGIC, HVGIC, GIC, compomer/PMRC, giomer vs Composite resin (CR), including bulk-fill composite

Occlusion · Children receiving dental restorations (aged 4-11 years; primary teeth; Class I/II/V cavities)

Occlusion was assessed in a single trial and was not pooled or GRADE-rated (ungraded).

Quantitative light-induced fluorescence (QLF) vs Reference standard (bitewing radiography, ADA classification, ICDAS II)

Occlusal caries detection: specificity · Patients (in vivo); permanent and primary teeth, occlusal surfaces

In vivo, QLF pooled specificity for occlusal caries in permanent teeth was 0.80 (3 studies; ungraded).

Veillonella spp. abundance

Future caries · Children without a previous history of caries

Veillonella spp. predicted future caries among children without a caries history, but no quantitative effect estimate was reported.

Replacement of the defective restoration vs Repair of the defective restoration

Amalgam: Preference for replacement over repair - Scenario 8: disruption of occlusal integrity · Dentists managing a defective direct amalgam restoration (posterior occlusal Class I; standardized vignette of a 30-year-old,…

For a defective amalgam restoration with disruption of occlusal integrity, surveyed dentists most often preferred replacement over repair (pooled RR 1.70; p < 0.001); ungraded.

Partial pulpotomy vs Full (complete) pulpotomy

Patient- and clinical-reported outcomes (tooth survival, clinical/radiographic success, pain) · Asymptomatic permanent teeth with deep caries (no symptoms)

No studies compared partial versus full pulpotomy in asymptomatic permanent teeth with deep caries, so no evidence is available.

Dental treatments, care, and services (the decision context) vs No comparator

Willingness to pay for dental care · (Potential) patients with freedom of choice regarding dental treatments, including parents and caregivers deciding for children or…

Across 37 willingness-to-pay studies, patients' WTP varied with treatment type and sociodemographic factors, being higher for aesthetic treatments (ungraded).

Gamified oral health interventions (mobile apps, serious games, augmented reality, game-based education) vs Conventional or traditional oral health education, or non-gamified interventions (comparator varied; several studies were single-arm/uncontrolled)

Adherence to oral hygiene routines by people with ID or their carers · Children or adolescents

Gamified interventions appear to increase children's engagement and adherence to oral hygiene routines, but the evidence is narrative and ungraded.

    Post-intervention (predominantly short-term; long-term follow-up in a minority of studies) · School-based settings, specialized dental clinics, and home-based environments
    The regular use rate was significantly higher (72.4%) in the gamified mobile health app group than in the nongamified intervention group (48.3%) [Zolfaghari 2021]; quiz-based challenges in mobile apps encouraged higher…

Higher drinking-water fluoride exposure vs Null / lowest drinking-water fluoride exposure (reference)

Fracture · general population

Non-linear positive dose-response: little change in overall fracture risk below ~1.5 mg/L drinking-water fluoride, with risk increasing above that threshold (RR 1.06, 1.19, 1.35 at 2.0, 3.0, 4.0 mg/L vs null); ungraded (4 studies).

Dental treatments, care, and services (the decision context) vs No comparator

Factors of choice influencing dental treatment decisions (overall) · (Potential) patients with freedom of choice regarding dental treatments, including parents and caregivers deciding for children or…

A wide range of factors (n=101 in three categories) influence patients' dental treatment decisions; the review identified and synthesized them qualitatively without grading certainty (ungraded).

Fluoride-releasing resin-based sealant vs Non-invasive measures (fluoride varnish; no intervention)

Radiographic proximal caries lesion progression · Children and adults with non-cavitated proximal (interproximal) caries lesions in primary and/or permanent teeth (ages 3-45)

Pooling 2 trials, resin-based sealants reduced radiographic proximal caries progression versus non-invasive measures (OR 0.24; ungraded subgroup).

Anorexia nervosa (as exposure; diagnosed by DSM-III/III-R/IV/V) vs Healthy controls

Percentage of bleeding on probing (BOP) · Patients with anorexia nervosa aged >=12 years (mean age ~18.4; entirely female in reported data), general community-dwelling population

Anorexia nervosa is associated with significantly increased bleeding on probing versus healthy controls (MD 16.57%, 95% CI 12.89 to 20.25; low certainty).
