The current evidence suggests no difference between the types of material s after 12 months but favours composite resin adhesives after a > 14-month period .
The clinical relevance of this study is that RM-GIC may have the same clinical debonding ( failure ) rate as composite resin adhesives after 1 year when used for bonding of orthodontic brackets
The aim of this systematic review was to establish whether the clinical debonding ( failure ) rates of orthodontic brackets bonded either with resin-modified glass ionomer ( RM-GIC ) or with composite resin adhesive  are the same .
Clinical and microbiologic evaluation of a resin modified glass ionomer cement for orthodontic bonding.
This study evaluated the clinical performance of a new resin modified glass ionomer cement , Geristore ( Den-Mat Corp. , Santa Maria , Calif. ) , for the bonding of orthodontic brackets and its effect on certain caries-associated microorganisms . This cement has been shown to possess increased mechanical properties and long-term fluoride release . There were 716 brackets bonded in 40 patients ( 17 males and 23 females ) , with a split-mouth technique and a composite resin , Phase II ( Reliance , Itasca , III . )  , as a control . Bond failures were recorded up to 1 year . Plaque scores and plaque sample s were taken from the area of the bonding adhesive in 20 patients , before , at 1 week , and 5 months after the placement of brackets . The plaque sample s were investigated for the presence of Streptococcus mutans and lactobacilli . The overall bond failure rate was found to be 8.9 % for Geristore and 3.1 % for Phase II ( p < 0.05 ) . Labially , there was no significant difference ( p > 0.05 ) in bond failure rate : 3.8 % for Geristore and 1.7 % for Phase II . The proportions of S. mutans and lactobacilli in plaque taken from around Geristore cement were reduced at 1 week and 5 months , when compared with Phase II resin , and this reduction was statistically significant ( p < 0.05 ) at 1 week . Results of this study suggest that Geristore may be of use in the labial segments , especially in caries prone patients , in whom demineralization at debond may present an esthetic and restorative problem several years after treatment
