Dental caries (carious oral microbiome) vs Caries-free / healthy oral microbiome

Differential microbial abundance / taxa predictive of caries · Individuals providing oral (saliva/supragingival plaque) 16S rRNA microbiome samples; 2016 samples from 19 studies (mixed children and…

A group of genera/species (notably Selenomonas, Aggregatibacter, Actinomyces, Treponema) was predictive of caries, whereas Streptococcus was not (ungraded).

Oral cavity microbiome (saliva and supragingival plaque samples); pooled across 19 international studies
Mean-decrease-accuracy discriminating taxa: Capnocytophaga HMT-338, Lactobacillus panis, Treponema HMT-230, Bifidobacterium longum, Delftia acidovorans, Staphylococcus schleiferi; higher log2FC in caries: Selenomonas HMT-146, Aggregatibacter actinomycetemcomitans, Actinomyces HMT-896, Treponema HMT-257; Streptococcus not predictive

Dental caries (carious oral microbiome) vs Caries-free / healthy oral microbiome

Discrimination of caries vs health (random forest ROC-AUC) · Individuals providing oral (saliva/supragingival plaque) 16S rRNA microbiome samples; 2016 samples from 19 studies (mixed children and…

Microbiome-based random forest classifiers could not reliably discriminate caries from health across the combined cohort (best AUC approximately 0.75 in a disease-only KO subset; ungraded).

Dental caries (carious oral microbiome) vs Caries-free / healthy oral microbiome

Alpha diversity (Chao1, Observed, Shannon) · Adults providing oral (saliva/supragingival plaque) 16S rRNA microbiome samples

In adults, caries-vs-health alpha diversity differed for the Shannon index but not Chao1/Observed (ungraded).

Oral cavity microbiome (saliva and supragingival plaque samples); pooled across 19 international studies · Adults
In adults, there was no significant caries-vs-health difference in Chao1 or Observed diversity, whereas the Shannon index differed significantly (p < 0.001).
