T allele of AMELX rs17878486 vs C allele of AMELX rs17878486

Dental caries susceptibility · Individuals assessed for dental caries (cases with caries/high caries vs. caries-free or low/very-low-caries controls)

No significant association between T allele vs C allele of AMELX rs17878486 and dental caries susceptibility (T vs C model: OR 2.87, 95% CI 0.35-23.23) in the Control group: Caries-free subgroup; certainty not graded.

CT genotype of AMELX rs2106416 vs CC genotype of AMELX rs2106416

Dental caries susceptibility · Individuals assessed for dental caries (cases with caries/high caries vs. caries-free or low/very-low-caries controls)

No significant association between CT genotype vs CC genotype of AMELX rs2106416 and dental caries susceptibility (CT vs CC model: OR 1.20, 95% CI 0.65-2.22) in the Ethnicity: Caucasian subgroup; certainty not graded.

All fluorescence-based devices (red, blue, and green fluorescence combined) vs Reference standard (histology, excavation, or enhanced visual examination)

Diagnostic odds ratio (DOR) by subgroup: Medium dentine-caries prevalence (15% to 34%) (detection of early enamel caries, D1 threshold) · Asymptomatic children, adolescents, or adults presenting for clinical examination (in vivo studies), or extracted teeth of children or…

Intraglandular botulinum neurotoxin (BoNT) injection vs No BoNT (placebo or pre-treatment baseline)

Salivary osmolality (hydration level) · Patients with drooling (sialorrhea) due to neurological disease

No included study reported salivary osmolality; this pre-planned outcome remains unassessed (no studies).

GG genotype of ENAM rs1264848 vs AA + AG genotype of ENAM rs1264848

Dental caries susceptibility · Individuals assessed for dental caries (cases with caries/high caries vs. caries-free or low/very-low-caries controls)

No significant association between GG genotype vs AA + AG genotype of ENAM rs1264848 and dental caries susceptibility (GG vs AA + AG model: OR 1.09, 95% CI 0.53-2.23) in the Ethnicity: Mixed subgroup; certainty not graded.

Intraglandular botulinum neurotoxin (BoNT) injection vs No BoNT (placebo or pre-treatment baseline)

Salivary S. mutans level · Patients with drooling (sialorrhea) due to neurological disease

BoNT injections were not associated with significant changes in salivary S. mutans counts across three studies (ungraded; no effect estimate reported).

  • Oral health effects of botulinum toxin treatment for drooling: a systematic review. 2020 All outcomes
    Before vs after BoNT injection · Neurological-disease populations with drooling (e.g., cerebral palsy, Parkinson disease, adults with sialorrhea); specialist clinical care
    The RCT by Wu et al. reported no statistically significant changes in S. mutans CFU counts (p-values only). The studies of Tiigimae-Saar did not find statistically significant differences in S. mutans CFU counts either.

Multiple LTF gene variants (joint / gene-based) vs Caries-free controls

Dental caries · Individuals assessed for dental caries (cases with caries/high caries vs. caries-free or low/very-low-caries controls)

A gene-based analysis indicated that multiple LTF variants were jointly associated with dental caries risk (weighted TPM P = 0.0007; no pooled effect estimate; ungraded).

TT genotype of AMELX rs2106416 vs CC + CT genotype of AMELX rs2106416

Dental caries susceptibility · Individuals assessed for dental caries (cases with caries/high caries vs. caries-free or low/very-low-caries controls)

No significant association between TT genotype vs CC + CT genotype of AMELX rs2106416 and dental caries susceptibility (TT vs CC + CT model: OR 1.67, 95% CI 0.44-6.34) in the Ethnicity: Caucasian subgroup; certainty not graded.
