The Oral Microbiome Research Group is a multidisciplinary team of scientists investigating the mechanisms by which oral bacteria regulate health and disease. Principal Investigators within the group have interests in hypertension, mouthwashes, dietetics, neuroscience, and oral cancer; all relating to the oral microbiome.
The approach is translational, with clinical trials are underway in human participants and with human tissue, as well as laboratory-based studies utilising metagenomics, physiological analysis, molecular biology, tissue culture and tissue engineering models.
Clinical trials also involve research led by the dental team, in primary care dental clinics (PDSE), to offer a variety of health screening services at the dentists.
