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.

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…

Fixed orthodontic treatment with fixed (multibracket) appliances (exposure) vs None (single-group prevalence/incidence estimate)

Incidence of new ICLs (mean number of new lesions per subject) · Patients undergoing fixed orthodontic treatment with fixed (multibracket) appliances, followed for development of new ICLs

Patients developed on average about 2.29 new ICLs during fixed orthodontic treatment (95% CI 1.12-3.46; very low certainty; very high heterogeneity).

Fixed orthodontic treatment with fixed (multibracket) appliances (exposure) vs None (single-group prevalence/incidence estimate)

Prevalence of ICLs (mean number of lesions per subject) · Patients (permanent dentition) during or after fixed orthodontic treatment with fixed (multibracket) appliances

Patients had on average about 2.24 ICLs per subject during/after fixed orthodontic treatment (95% CI 1.79-2.70; very low certainty; very high heterogeneity).

Pulpotomy (full or partial) vs None (single-arm success proportion)

Overall success (composite of clinical and radiographic success) · Permanent teeth with carious pulp exposure

Hemostasis within 6 min gave the highest success (90.4%), but the difference across hemostasis-time groups was not significant (ungraded).
