Objectives
To assess whether RMGIC release more fluoride than fluoride-containing composite resin.
Search strategy
The trials were identified from a search of the PubMed database on: May 21, 2009 using the terms: Glass Ionomer Cements"[Mesh] AND "Composite Resins"[Mesh]) AND "Fluorides"[Mesh] followed by reference check of included articles.
Inclusion criteria
All prospective 2-arm in-vivo or in-situ trials; with relevance to review question including computable data; published in English.
Data collection and analysis
The systematic literature search found 47 trials of which 32 were identified to be in line with the inclusion criteria. Of these, 30 trials could be traced for review. From the reviewed trials 466 individual datasets were extracted and analyzed.
Main results
The overall result of the in vitro trials showed a higher fluoride-releasing efficacy of RMGIC than fluoride-containing composite resin. This was not confirmed, however, by the results of the single in vivo trial, which showed no difference in the fluoride content of plaque adjacent to Class III restoration with either material.
Authors' conclusions
The results of in vitro studies indicate that resin-modified glass ionomer cements (RMGIC) have a higher fluoride-releasing efficacy than fluoride-containing composite resin. These findings need to be confirmed in vivo
