Title Resin Modified Glass Ionomer Restorations Placed in Non-Carious Cervical Lesions Have Similar if Not Better Retention Rates Than Resin Composites
Clinical Question For a patient with a non-carious class V restoration, how does the failure rate for resin modified glass ionomer restorations compare to resin composite restorations?
Clinical Bottom Line With limited evidence being available, retention of RMGI restorations for non-carious cervical lesions appear to outperform RC ones. (See Comments on the CAT below)
Best Evidence (you may view more info by clicking on the PubMed ID link)
PubMed ID Author / Year Patient Group Study type
(level of evidence)
#1) 11355096Folwaczny /2003197 class V restorations placed by one dentist in 37 patients on incisors, canines and premolars.Randomized Controlled Trial
Key resultsAfter 36 months there was no statistical difference between the retention of the resin modified glass ionomers and resin composites used. At the end of the study one resin composite restoration (Tetric) and five resin modified glass ionomer restorations (two Fuji II LC and three Photac) were lost.
#2) 16924979Franco/200622 oatientsRandomized Controlled Trial
Key resultsTwenty-two patients were evaluated after 5 years (73.3% recall rate) and 55 out of 70 restorations were evaluated. When Comparing both materials, the Fisher exact test revealed significant differences in retention (p=0.002) after 5 years of clinical service with the RMGI being superior.
Evidence Search resin modified glass ionomer and resin composite and cervical
Comments on
The Evidence
The clinical trials extended 18 months or more. One double blind study was performed and intra-examiner results were compared.
Applicability The results are applicable to any patient requiring restoration of non-carious cervical lesions.

We conducted a PubMed search on this topic in August 2013. We found a 2-year controlled clinical trial published in 2010 (Santiago, PMID # 21203706 ) that compared a one bottle etch-and-rinse adhesive and composite system with a resin modified glass ionomer in non-carious cervical lesions. It had a similar conclusion to this CAT, that resin modified glass ionomers have superior retention in non-carious cervial lesions.
