Title Longevity Of Resin Composites Compared To Glass Ionomers
Clinical Question In a class II restoration, does the benefit of a fluoride releasing restoration such as Fuji more beneficial than the longevity of a resin restoration?
Clinical Bottom Line No, due to the fact that in a class II restoration in the posterior teeth, the strength of a glass ionomer is not as strong as a resin composite. There really are not many types of glass ionomers on the market at the moment, but with time this might be changed. (See Comments on the CAT below)

(level of evidence)
#1) 18041507Toh/200750 Clinical StudiesMeta Analysis
Key resultsOverall success rates were: (1) GIC (691 restorations)=75%; (2) RmGIC (276)=89%; (3) CR (620)=83%; (4) PAMCR (596)=87%. Glass ionomers had the highest success rates, but also the fewest studies and fewest restorations with only one product being assessable.
#2) 20638116Heintze / 201036 Clinical Trials which 25 of which were RCTsMeta Analysis
Key resultsRestorations placed in teeth whose dentin/enamel had been prepared showed a statistically significant higher retention rate than those placed in teeth with unprepared dentin (p<0.05).
#3) 10716002Downer /1999124 Research ReportsSystemic Review
Key resultsRestoration type, materials, the patient, the operator, the practice environment and type of care system appeared to influence longevity. Many studies were imperfect in design. Those considered being the most appropriate for analysis were too limited to undertake a formal statistical exploration. More proper studies need to be correlated in order for a proper result.

Comments on
The Evidence
There was not much research done on the topic since there are limited choices when it comes to glass ionomers. In the future, more research is needed to get a more reliable answer.
Applicability This is not really applicable at the moment because of the limited glass ionomer products available at the moment.
