Dalhousie to host symposium May 2014

Light curing of white resin fillings have been a heavily researched topic for Dalhousie’s Dr. Richard Price. However, the negative impact of under curing resin fillings is not generally well known.

Dr. Price has organized a two-day symposium to take place at Dalhousie University May 29th and 30th, 2014 aimed at discussing light curing and to develop strategies to educate other practitioners about the proper use of curing lights.

The following key opinion leaders from the USA, Canada, Brazil, United Kingdom, Germany, Liechtenstein, and Norway will attend this meeting. Topics will include how manufacturers can improve the design of curing lights, the potential negative impacts of using the cheaper, unbranded curing lights that are widely available online, and strategies to better inform dentists on the proper use of curing lights.
