Oral Biology


My research is within the field of oral and dental tissue inflammation and repair. Current areas of research interest include:

1. Dentine-Pulp complex biology
Paul has led projects studying the molecular changes which occur in the dentine-pulp complex as a result of disease, dental injury and repair, and in its response to dental materials. PhD projects he has supervised have characterised dental pulp stem cells (DPSC) responses with the aim of developing novel treatment technologies.

2. Molecular and Cellular aspects of Periodontal Disease
Paul has led studies characterising oral epithelial or neutrophil responses to periodontal bacteria. In collaboration his work has shown that elevated systemic levels of IFNs are associated with the disease. Subsequently this has led to further studies on the roles of Neutrophil Extracellular Traps (NETs), auto-immunity/-inflammation, DNAse deficiency, epigenetics and efferocytosis in periodontitis and its comorbidities.

3. Low Level Light/Laser Therapy (LLLT) / photobiomodulation / phototherapy
Recent studies indicate the utility of phototherapies in promoting oral and dental tissue health as well as for disinfection. Different light delivery approaches are being explored to identify delivery parameters which modulate dentine-pulp complex, gingival and immune cell responses relevant to tissue health.

4. Assessment of toothpaste cleaning
Industry funded studies have utilised profilometry, gloss analyses, stain models and SEM to investigate mechanistic actions of dental dentifrices for oral hygiene.
