The relative degree of conversion of the composite resin surface


Abstract
The purpose of this study was to evaluate the changes in the degree of conversion on a composite resin surface following heat treatment and mylar strip finishing. The effects of the time interval between the light-curing and heat-curing process
were
also evaluated.
The composite resin surface which had been covered with a coverglass showed a lower conversion rate than the surface from which a layer of 500§­ was ground away.
The composite resin surface was definitely affected by oxygen during the heat curing process when it had not been insulated.
When the composite resins were heat cured after 3 days of storage following the light curing process, the increased in the degree of conversion through heatcuring was limited.
