Problem-driven / less regular dental visiting vs More frequent / regular dental visits

Dental caries · Healthy children and adolescents in the United Arab Emirates

A higher frequency of dental visits was associated with lower caries, while problem-driven visiting was associated with higher severe early childhood caries (narrative synthesis; not GRADE-rated).

Utilization of dental services assessment (care/restorative index; dental visits) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Dental service utilisation within the past year · Healthy Emirati preschool children in the United Arab Emirates

Utilization of dental services among healthy Emirati preschoolers was very low, with most children never having visited a dentist and very low care indices (narrative synthesis; not GRADE-rated).
