Relationship of tongue coating microbiome on volatile sulfur compounds in healthy and halitosis adults
This study aims to assess the microbiome variations related to intraoral halitosis and its
relationship with volatile sulfur compounds (VSCs) among periodontally healthy Chinese adults.
Material and methods : Tongue coating samples were collected from 28 periodontally healthy subjects
(16 subjects with halitosis and 12 subjects without halitosis) who fulfilled the selection criteria.
The organoleptic score (OS) was used to evaluate the halitosis status. The characterization of
associated microbial communities was performed using 16S rRNA gene pyrosequencing and metagenomics
methods. Results : A wide range of microbial communities, including 13 phyla, 23 classes, 37 orders,
134 genera, 266 species and 349 operational taxonomic units (OTUs), were detected. The Shannon index
values were significantly higher in the halitosis group. Genera, such as Prevotella, Alloprevotella,
Leptotrichia, Peptostreptococcus and Stomatobaculum , exhibited signifi...
