title: A twelve-month clinical trial comparing the bracket failure rates of light-cured resin-modified glass-ionomer adhesive and acid-etch chemical-cured composite.
abstract: A clinical study was undertaken to compare the failure rate over a twelve-month period of orthodontic brackets bonded with a light-cured resin-modified glass-ionomer (Fuji Ortho LC-GC International Japan) and an acid-etch chemically-cured two-paste composite (Orthodontic Concise-3M USA). Failure rates of 6.1 per cent and 5.4 per cent respectively were reported, with no statistically significant difference between the two adhesives. This finding, along with the relative ease of use and possible advantages of reduced risk of peri-bracket demineralisation, suggests that the resin-modified glass-ionomer adhesive may become more popular as a bracket adhesive.
