Discovery could lead to stronger dental fillings…and less time at the dentist

An international team of researchers used the Canadian Light Source (CLS) at the University of Saskatchewan to discover how to create stronger dental fillings. This is great news for the estimated 96 per cent of Canadians who will have to contend with at least one cavity during their adult lives.

For the first time, an international group of researchers led by Professor Owen Addison from King’s College London has been able to close a gap in the knowledge of photo-activated resin-based composites, commonly used in medical and dental applications.

In a recent paper published in Nature Communications, the team from Alberta, the United Kingdom, Norway and the United States described how they saw inside the resin matrix and gained insight into how filler particles interact with it during setting and influence the dental filling materials.
