title: A 12-month clinical evaluation of a light-activated glass polyalkenoate (ionomer) cement for the direct bonding of orthodontic brackets.
abstract: Glass polyalkenoate cements have the unique properties of physicochemically bonding to enamel and base metals and to leach fluoride over prolonged periods. These cements have been modified to provide a dual setting with both light activation and chemical cure to produce a more rapid set. This article reports a 12-month clinical trial of a light-activated glass polyalkenoate cement for the direct bonding of orthodontic brackets, compared with a standard composite bonding adhesive. There was no significant difference in failure rates of direct bonded orthodontic brackets cemented with Fuji II LC light-activated glass polyalkenoate cement (GC Industrial Co., Tokyo, Japan) (3.3%) compared with System I+ composite bonding resin (Ormco Corp., Glendora, Calif.) (1.6%).
