Research interests My research interests are preventive dentistry, cariology, evidence based dentistry, research in primary care and child focused research. I am the Chief Investigator on the NIHR MAGIC Trial looking at melatonin as a premedication for GA. In the fielded of cariology I was a co-investigator on the FICTION Trial and am currently part of the teams delivering the SCRIPT (Selective Caries Removal in Permanent Teeth) and PIP (Pulpotomy in Permanent teeth) Trials. I am particularly interested in improving caries diagnosis because I believe this will improve patient outcomes. My research has looked at both meticulous visual caries diagnosis and the use of diagnostic aides and devices. Current and planned research is examining the remineralisation of dentine and the structure of carious lesions. I am member of the International Caries Detection & Assessment System (ICDAS) Co-ordinating Committee, which is redefining the research, clinical and educational agenda in cariology.
