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, 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 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.
