[The measurement of the tooth-restoration material gap: the value of SEM].
The purpose of this article was to describe a method of measuring the interface between cavity walls and restorative materials and to evaluate it by comparing the interface of amalgam, composite restorations and cavity walls. With the different restorative materials the interface could be measured. Its value was dependent of the type of restoration. This methodology is available for all restorative biomaterials. It could be of interest in clinical evaluation of restorative materials.
