Dr. Justine Kolker, Department of Operative Dentistry, has been selected to attend the International Caries Classification and Management System (ICCMS) Workshop, which will be held in London (UK) between June 3 and 5, 2013.

By Dr. Kolker’s participation in the workshop, the College of Dentistry will become a member of the Collaboratory. A Webinar on the ICCMS and expectations in London will be held in April or May for the selected U.S. representatives. The protocols will be disseminated via an interactive online educational program and eventually will be incorporated in clinical management systems such as Axium and Dentrix. The ICCMS will provide $3,000 in travel support for each representative selected to attend. Funding is available for 20 representatives from the U.S.
