  • Research summary

    Periodontal diseases are common inflammatory disorders of the gums that can result in teeth becoming loose, or even lost. Current diagnostic techniques are somewhat crude and insensitive, and only provide a historical picture of disease activity. By the time that disease can be detected using currently available techniques (the periodontal probe and x-rays), disease has already developed.

    We are trying to improve this situation by moving towards the development of better diagnostic techniques for the early detection of disease (e.g. before it is evident clinically) using molecular analysis of saliva. We have received funding to start to develop a biosensor for key molecules in the saliva that could indicate presence of periodontal disease. The study involves 3 phases: (i) a calibration phase to ensure accurate and reproducible measurements by examiners (essential for any clinical periodontal studies), (ii) a periodontal treatment study in which patients with various periodontal conditions receive their routine clinically-indicated treatment, with saliva samples being collected over the course of the treatment, and (iii) an experimental gingivitis study, in which gum inflammation is induced (reversibly) in healthy volunteers, by asking them to refrain from tooth brushing in a quarter of their mouth for a period of three weeks. The saliva samples will be analysed in the laboratory, using both conventional analysis techniques, as well being used to help develop the new biosensor technology and compare its results to conventional analysis methods.
