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 .
A Clinical Investigation of the Effects of Omission of Pumice Prophylaxis on Band and Bond Failure
One hundred and twelve first molar b and s and 614 directly bonded brackets on incisor , canine , and premolar teeth were included in a clinical trail to investigate the importance of omission of pumice prophylaxis at the time of b and ing and bonding , on their possible subsequent failure . Half of the sample were selected for the non-pumiced test groups using a r and om number allocation method , the remaining pumiced teeth acting as control groups . Two etch times were used for the direct bonding part of the study , 15 and 60 seconds , with non-pumiced test and pumiced control groups included within both etch-time groups . Results showed no statistical difference in the failure rate of attachments in either test or control groups during the course of treatment . The different etch times had no significant effects in the direct bonding part of the study
