Objectives
To assess whether from restorations of comparable size, does RMGIC release more fluoride than compomers.
Search strategy
The trials were identified from a search of the PubMed database on: May 21, 2009 using the terms: "((("Elan (compomer) "[Substance Name] OR "MagicFil "[Substance Name] OR "Dyract Flow Compomer "[Substance Name] OR "Freedom Compomer "[Substance Name] OR "dyract flow "[Substance Name] OR "compoglass flow "[Substance Name] OR "Vivaglass Fil "[Substance Name] OR "Vivaglass Cem "[Substance Name] OR "Dyract "[Substance Name])) AND "Glass Ionomer Cements"[Mesh]) AND "Fluorides"[Mesh]", followed by reference check of included articles.
Inclusion criteria
All prospective 2-arm in vitro, in situ or in vivo trial; with relevance to the review question including computable data; published in English.
Data collection and analysis
The systematic literature search found 38 trials of which 24 were identified to be in line with the inclusion criteria. Of these, 22 trials could be traced for review. From the reviewed trials 481 individual datasets were extracted and analyzed.
Main results
The overall results of the in vitro trials showed a higher fluoride-releasing efficacy of RMGIC than Compomers. This was not confirmed, however, by the result 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 (laboratory) trials indicate that resin-modified glass ionomer cements (RMGIC) have a higher fluoride-releasing efficacy than Compomers.
