Tooth wear assessment (primary teeth) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Tooth wear prevalence · School children (primary dentition) in the United Arab Emirates (Abu Dhabi)

One study reported a very high prevalence of tooth wear (97.6%) in the primary dentition of school children in Abu Dhabi, associated with older age, mouth breathing and anterior deep bite (narrative synthesis; not GRADE-rated).

Dental plaque assessment (plaque score/index) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

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).

Oral hygiene knowledge and practices assessment vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Oral hygiene knowledge and practices · Children and adolescents in the United Arab Emirates

Oral hygiene knowledge and practices among UAE children and adolescents were generally suboptimal and variable across studies, with better practices among females (narrative synthesis; not GRADE-rated).

Molar-incisor hypomineralisation (MIH) assessment vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

MIH prevalence · School-aged children in the United Arab Emirates (Dubai)

MIH prevalence among school-aged children in Dubai ranged from 7.6% to 27.2% across two studies, higher in females and low-socioeconomic-class schools (narrative synthesis; not GRADE-rated).

Gingivitis (assessed by gingival index or WHO criteria) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Gingival health at 6 months · Children and adolescents in the United Arab Emirates (Sharjah)

Gingivitis and high plaque levels were common among UAE children and adolescents, more likely in females and older children (narrative synthesis; not GRADE-rated).

1 finding from 1 review

Oral health knowledge, attitudes and practices assessment vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Mother self-reported oral health behaviours and attitudes · Mothers and caregivers of children in the United Arab Emirates

Mothers and caregivers often had adequate knowledge/attitudes but improper oral-health practices and low dental-service use, associated with education and occupation (narrative synthesis; not GRADE-rated).

Caries assessment at dentine threshold (cavitation into dentine) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Dental caries prevalence · European adolescents aged 12–19 years

Caries prevalence at the dentine threshold was about 56% (pooled 0.56, 95% CI 0.43 to 0.68; 15 studies; not GRADE-rated).

Dental caries assessment (WHO/clinical diagnostic criteria; caries = DMFT>0) vs None (descriptive prevalence; random-effects pooled proportion)

Dental caries prevalence · Children (deciduous and/or permanent dentition) in low- and middle-income countries

About 39% of children in LMICs had dental caries (pooled prevalence 0.387, 95% CI 0.284 to 0.495; 11 studies; very high heterogeneity I2=99%; not GRADE-rated).

Caries distribution assessment (individual, tooth and surface levels) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Caries distribution (individual/tooth/surface level) · European adolescents aged 12–19 years

Caries distribution was skewed at individual, tooth and surface levels and too heterogeneous to meta-analyze (narrative synthesis of 11 studies; not GRADE-rated).

1 finding from 1 review

Dental caries assessment (WHO/clinical diagnostic criteria; caries = DMFT>0) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

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

Dental caries is highly prevalent among children and adolescents in the UAE, ranging from 22% to 99.4% across cross-sectional studies (narrative synthesis; not GRADE-rated).

1 finding from 1 review

Dental caries assessment (WHO/clinical diagnostic criteria; caries = DMFT>0) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Dental caries prevalence · 12-year-old children (permanent dentition) in Africa

Pooled caries prevalence in Uganda was 0.27 (95% CI 0.126 to 0.418; 3 article(s); 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).

Caries assessment at enamel threshold vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Dental caries prevalence · European adolescents aged 12–19 years

Enamel-threshold caries prevalence in subgroup 'Region: non-Scandinavian' was 0.74 (95% CI 0.53 to 0.96; 11 studies).

Original development of CAMBRA (Caries Management by Risk Assessment) or CAT (Caries-risk Assessment Tool) multivariable models vs Not applicable

Model development with reported performance measures (per CHARMS) · Individuals of any age at risk of caries increment

No original CAMBRA or CAT model-development studies reporting performance measures according to CHARMS were found (evidence gap); these tools appeared only as validated models within other studies.
