Using bioinstrumentation, imaging, bespoke design of active delivery models and sampling techniques, we conduct in-depth evaluations of oral malodour assessment, abrasivity, erosion and tissue loss, microhardness, stain removal and whitening, anti-plaque and anti-calculus, and cleaning evaluations of toothbrushes, interdental brushes, flosses and tapes. We also offer tissue preparation (e.g. human and bovine enamel or dentine), dental restoration materials, and artificial lesion preparation and bioanalytical solutions for clinical samples such as plaque, saliva or gingival crevicular fluid.We are ISO 9001 accredited and licensed by the Human Tissue Authority (HTA) for storage of human tissue.
