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…

Plaque · Children in the United Arab Emirates (Ajman, Sharjah)
Dental plaque levels were high and associated with frequent snacking and less frequent tooth brushing, and higher plaque was linked to more caries (narrative synthesis; not GRADE-rated).
