Cleft lip and/or palate (CL/P) vs No cleft lip and/or palate (non-CL/P)

Restorative index (RI = f/[d+f]) in the primary dentition · Children in the primary dentition with non-syndromic cleft lip and/or palate (CL/P) and comparable children without CL/P

The restorative index tended to be lower in children with CL/P (3 of 5 studies), indicating a lower proportion of restoratively managed carious teeth; not pooled (narrative; ungraded).

  • Caries in children with and without orofacial clefting: A systematic review and meta-analysis. 2022 All outcomes
    Children with CL/P and comparable non-CL/P children across 12 countries (India, Brazil, China, Sweden, UK, USA, Germany, Greece, Ireland, Netherlands, Jordan, Thailand); studies published 1989-2021
    Of the five studies for which the RI could be calculated, three of them (Dahllof 1989; Nagappan 2019; Veiga 2016) showed a lower RI for children with CL/P compared to children with no CL/P demonstrating a lower…

Selective carious tissue removal (selective excavation, SE) vs Non-selective or complete carious tissue removal

Pulpal disease (signs/symptoms of pulp necrosis) · Children with dentine caries in primary and permanent teeth

The reported estimate did not show a clear difference in pulpal disease after partial versus complete caries removal (ungraded).

Genetically predicted gene expression (TWAS; S-PrediXcan with GTEx v8 cis-eQTL across 49 tissues; cross-tissue S-MultiXcan) vs ECC-unaffected children (association of genetically predicted expression)

Early childhood caries (ECC) - association with genetically predicted expression of CDH17 (chr8q22.1) · Children up to age 5-6 years (European / European non-Hispanic ancestry); 843 ECC-affected vs 2124 unaffected across 5 cohorts (N=2974)

Genetically predicted expression of CDH17 was significantly associated with ECC in the TWAS (p = 3.32e-8); genetic association, ungraded.

Conventional bitewing radiography, F-speed film vs Histological validation of dental tissues (gold standard)

Diagnostic accuracy for proximal caries detection (caries detection level) · Extracted permanent posterior teeth with proximal surfaces (in vitro)

Under in vitro conditions, conventional F-speed bitewing radiography had a summary ROC AUC of 0.72 for proximal caries detection at the caries detection level; ungraded.

TaqI (rs731236 T>C) polymorphism in the VDR gene (C allele / variant genotype) vs CT/CC genotype vs TT genotype (dominant model)

Dental caries susceptibility · Children and adults (no age limit) assessed for dental caries susceptibility

No significant association between the TaqI (rs731236 T>C) polymorphism and dental caries for mixed dentition caries under the dominant (CT/CC vs TT) model (OR 1.37, 95% CI 0.81 to 2.33); ungraded.

Fluoride-releasing glass ionomer-based bonding agent vs Non-fluoride glass ionomer-based bonding agent

Initiation of white spot lesions (WSL), visual-tactile assessment · Patients of any age (11-40 years) receiving comprehensive/fixed orthodontic treatment with fixed appliances

For a glass-ionomer-based bonding agent (single study), fluoride release significantly reduced WSL initiation (RR 0.64); subgroup not separately GRADE-rated.

Laser fluorescence (DIAGNOdent 2190/pen) vs Histological validation of dental tissues (gold standard)

Diagnostic accuracy for proximal caries detection (dentin detection level) · Extracted permanent posterior teeth with proximal surfaces (in vitro)

Under in vitro conditions, laser fluorescence (DIAGNOdent 2190) had a summary ROC AUC of 0.83 for proximal caries detection at the dentin detection level; ungraded.

TaqI (rs731236 T>C) polymorphism in the VDR gene (C allele / variant genotype) vs CC genotype vs TT genotype (homozygous model)

Dental caries susceptibility · Children and adults (no age limit) assessed for dental caries susceptibility

No significant association between the TaqI (rs731236 T>C) polymorphism and dental caries in Asians under the homozygous (CC vs TT) model (OR 1.38, 95% CI 0.55 to 3.50); ungraded.

Presence of dental plaque vs Absence of dental plaque

Dental caries · Individuals in Ethiopia assessed for dental caries

The presence of dental plaque was not significantly associated with dental caries (OR 5.14, 95% CI 0.67 to 39.39); certainty not graded.

Conventional bitewing radiography (E-speed film) vs Histological validation of dental tissues (gold standard)

Diagnostic accuracy for proximal caries detection (caries detection level) · Extracted permanent posterior teeth with proximal surfaces (in vitro)

Under in vitro conditions, conventional E-speed bitewing radiography had a pooled sensitivity of 0.42 (95% CI 0.28, 0.57) for proximal caries detection at the caries detection level; ungraded.
