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 .
The effect of pumicing on the in vivo use of a resin modified glass poly(alkenoate) cement and a conventional no-mix composite for bonding orthodontic brackets.
OBJECTIVE Pumicing of the enamel prior to direct bonding with conventional diacrylate bonding agents has been shown to be unnecessary . It is not known whether this is also the case with resin-modified glass poly(alkenoate ) cements . The aims of this study were two-fold : ( a ) . to determine whether pumicing prior to bonding has an effect on the in vivo failure of brackets bonded with either Right-On or Fuji II LC ; ( b ) . to determine whether there is a difference in the in vivo failure of brackets bonded with either Right-On or Fuji II LC . Design A cross-mouth controlled clinical trial was performed on a total of 60 patients in which the variables under test were pumicing or not pumicing of the enamel prior to bonding using two different bonding agents  . MAIN OUTCOME MEASURES The measurement variable was bond failure over an 18-month period . RESULTS AND CONCLUSIONS Prior pumicing of the enamel has no effect on in vivo failure when using either a conventional diacrylate or a resin modified glass poly(alkenoate ) cement . A greater number of bonds failed with the resin-modified glass poly(alkenoate ) cement
