Dental cavity liner (e.g. calcium hydroxide, glass ionomer, resin-modified glass ionomer, or flowable composite) placed under the restoration vs No cavity liner or a different liner material

Secondary prevention of caries · Patients with deep caries lesions in mature or immature permanent (posterior) teeth, with no symptoms or reversible pulpitis

Cavity liners may make little or no difference to secondary caries prevention (~100% prevention across groups; low certainty).

HIV-infected children on antiretroviral therapy (HI) vs HIV-unexposed uninfected children (HUU)

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

HIV-infected children on ART had higher odds of dental caries than HUU children in case-control studies (OR 1.61, 95% CI 1.02 to 2.56; ungraded).

Oral hygiene behavior (brushing habits, preventive dental visits, dietary choices) · Children or adolescents

Gamified interventions appear to improve oral hygiene behaviors (brushing habits, preventive dental visits) in children, 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
    A gesture-based motion-capture game enhanced brushing independence and skill retention (P<.001) [Kang 2021]; 58.8% of caregivers reported their children brushed more often when using gamified applications [France…

Composite: Preference for replacement over repair - Scenario 6: superficial discoloration · Dentists managing a defective direct resin composite restoration (posterior occlusal Class I; standardized vignette of a 30-year-old,…

For a defective composite restoration with superficial discoloration, surveyed dentists most often preferred repair over replacement (pooled RR 0.28; p < 0.001); ungraded.
