Long in the Tooth - The Physics of Tooth Repair. Tooth decay is generally considered to be the most prevalent of all human diseases.  

For over 150 years, decayed teeth have been repaired with unsightly silver amalgam, but in the last 40 years or so, there has been a revolution in the materials available, and contemporary clinicians have a choice of natural-looking materials that can be used with minimal damage to the remaining healthy tooth tissue.  One of these materials is the glass-ionomer cement, which is highly bioactive, and capable forming a durable adhesive bond to the tooth surface. 

These features have led to novel "drill free" dental treatments becoming available.  In this lecture, Professor Nicholson will review the current state of the art of these materials, and emphasise his own contribution to our understanding of their properties and behaviour.
