Main Interests

My research career started around 1970 after practicing dentistry for several years. Initially, my research focused on investigating dental amalgams and their use. However, during the mid 70s I realized and foresaw that the future of restorative dentistry would be to develop improved dental composite resins and dental adhesives.

In 1977-1978, I worked at the Scandinavian Institute of Dental Materials in Oslo, Norway, where my key responsibility was to run the different testing programs for cements and elastomeric impression materials available on the Scandinavian market. At the same time, I continued working on different composite projects.

As time has passed, my research has focused on degradation mechanisms of different filler systems and degradation mechanisms of resins. One such study was a NIDCR funded clinical study in which different degradation mechanisms were evaluated clinically. Other projects have dealt with different dentin adhesives and their technique sensitivity. During the last few years a key research interest has been to develop an understanding of the different variables affecting light-cured dental composites. A goal with that project is to develop systems that can be bulk-cured within a minimal amount of time without inducing significant stress levels in the surrounding tooth structures.
