The Paediatric Caries Research Program falls under the “Diagnosis & Prevention of Oral Disease” research theme, and has a multi-focus approach to caries research. The research is both clinical and laboratory-based, including microbiological investigations. Current studies examine strategies for diagnosis, prevention and management of caries in children, and research projects examine the aetiology and risk factors for early childhood caries, efficacies and cost-benefits of preventive methods and treatment strategies for management of caries in children. Clinical studies are undertaken at Queensland Health facilities at Logan-Beaudesert District while laboratory research is based at the School of Dentistry.
Current research projects focus on the prevention of early childhood caries in a low socioeconomic, disadvantaged district of Queensland. Longitudinal studies of children from birth to six years of age are progressing well. These examine the colonisation of children with cariogenic bacteria, timing of caries development and efficacy of various techniques for prevention of early childhood caries. Randomised controlled clinical trials on the effectiveness of various therapeutic agents such as casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and chlorhexidine are being conducted. The clinical investigations have been extended to include studies of twin children, as well as investigations on role of mutans streptococci and other dental biofilm bacteria in caries development using real-time PCR techniques. Studies into innovative approaches for restorative and pulp therapy for management of early childhood caries are planned.
