10 March 2016
Time: 5:30 - 6:30pm
Venue: Arts Two Lecture Theatre, Mile End
Professor Paul Anderson, Professor of Oral Biology, will be giving his inaugural lecture entitled By the skin of my teeth: the enamel-saliva continuum in March.
Dental enamel is a remarkable natural hierarchically structured biomaterial, capable of withstanding high mechanical forces, and, the harsh chemical destructive forces within the oral environment. Nevertheless, enamel can still be destroyed as a consequence of oral diseases such as caries. Unfortunately, there are no cellular regenerative processes for re-growing damaged enamel within the oral environment, so the natural enamel repair process has to be from the oral environment. Saliva contributes significantly to the protection and repair processes of enamel, including saliva derived proteins that form a thin layer on the enamel surface. This peptide “skin” of teeth serves to protect enamel surfaces from acidic attack by influencing the surface chemistry of calcium hydroxyapatite, the mineral component of enamel. Novel X-ray microscopic methods have been developed that have assisted in these studies of the enamel-saliva continuum.
Paul graduated in biophysics from Leeds University, and then a PhD in dental biophysics from London University. He was appointed Professor of Oral Biology in 2014. His main research interests are the cariostatic efficacy of salivary proteins and metal ions on enamel and chemical analogues, and the development of X-ray microscopy.
The event will be followed by a reception in the SCR bar, 2nd Floor, Queens’ Building, Mile End.
