Initiation of white spot lesions (WSL), visual-tactile assessment · Patients of any age (11-40 years) receiving comprehensive/fixed orthodontic treatment with fixed appliances
Fluoride-releasing coating materials do not appear to reduce WSL initiation more than non-fluoride coatings (RR 0.84, not significant); certainty of evidence is very low.

Dental caries · Healthy children and adolescents in the United Arab Emirates
Evidence on socioeconomic status/income and caries was inconsistent: some studies linked lower income to higher caries while others found no association (narrative synthesis; not GRADE-rated).
1 finding from 1 review
Findings were contradictory. Hashim et al. found children from low-income families had higher odds of severe early childhood caries (OR 1.43, 95% CI 1.11-1.85), and Ahmad et al. reported significantly higher DMFT in…

detection of proximal caries · Permanent posterior teeth, proximal surfaces (in vitro extracted teeth and in vivo patients)
For fibre-optic transillumination (FOTI), studies were identified (in vitro N=4, in vivo N=3) but none had sufficiently low risk of bias and adequate reporting to be pooled; no meta-analytic estimate could be derived.
