简要总结
Dental caries is a major public health probleme the result of hard tissue demineralization and oral microbiota changes.
Methanogenic archaea, mainly Methanobrevibacter oralis, are associated with various oral problems, including pathologies periodontal.
Previous research has not really studied the Archaea in carious lesions, hence the importance of our study.
Our study aims to explore their potential role in the the development of caries by analysing their prevalence and their quantification in relation to the carious risk individual. The aim is to improve understanding of the Cavity microbiology to advance management of this pathology in terms of prevention or of treatment.
Our team is particularly competent in the field of Archaea, especially in the cultivation of Archaea methanogens since we have a dedicated platform. We also discovered the first human Nanoarchaea, opening up a whole new possible search field.
