| Study Title | Multi-omic analysis reveals bacteria may have a role in dental erosion |
| Study Type | Research Study |
| Study Summary | NMR was performed on 11 saliva samples; 5 from participants classified as having dental erosion and 6 from healthy control participants with no dental erosion to assess the differences in metabolome between the two groups. NMR analysis alone revealed no significant differences between the dental erosion and healthy controls. However, bacterial mRNA sequencing of the oral microbiome from the same saliva samples was performed and the bacterial gene expression profiles was correlated to metabolite concentrations in the groups. The dental erosion group had strong correlations between metabolites associated with protein degradation and amino acid fermentation (formate, butyrate, propionate, 5-aminopentanoate, acetate, glycine, phenylalanine, dimethyl sulfone) and increased activity of species including 4 Prevotella species, Actinomyces graevenitzii, Tannerella species, and 2 Selenomas species, to name a few. Whereas in the healthy control group, the only positive correlations between metabolite concentrations and bacterial activity was for urea and 5-aminopentanoate; urea was positively correlated with Aggregatibacter actinomycetecomytans, Lysinibacillus fusiformis, and Veillonella tobetsuensis, and 5-aminopentanoate was positively correlated with 3 different Leptotrichia species, Streptococcus parasanguinis, and 2 Prevotella species. |
