Abstract

Four clinical trials were found. The limited number of clinical trials is surprising considering that the topic of GIC/Composite sandwich restorations was very popular 20 years ago. However, the bulk of research studies appeared to be limited to a very large number of laboratory (in-vitro) trials, only. Although important to clarify material characteristics, laboratory trials are unable to provide information how well these restorations really perform in the clinic, particularly in comparison to direct composite restorations.


The results indicate no difference between sandwich restorations (with RM-GIC or conventional GIC) after 2 years. Post-operative sensitivity appears to be a lesser problem with RM-GIC/Composite restorations.
The current level of clinical evidence to this topic appears to some extent contradictive and may still be limited in quantity and quality. Thus more trials are needed in order to confirm the current results.
