Abstract
Data sources The Cochrane Oral Health Group’s Trials Register, the Cochrane Central Register of Controlled Trials, Medline and EMbase, up to August 2002, were used to identify publications.
Study selection Selected studies were randomised controlled trials (RCT) and controlled clinical trials that compared two different adhesives in subjects who required fixed orthodontic appliances and where the intervention was adhesive bonding of stainless steel brackets to all teeth except the molars. The primary outcome was debond or bracket failure.
Data extraction and synthesis Data were recorded for decalcification as a secondary outcome, if present. Information regarding methods, participants, interventions, outcome measures and results were extracted in duplicate by pairs of reviewers. Since the data were not amenable to meta-analysis, the results are presented in narrative form only.
Results Three trials satisfied the inclusion criteria. A chemically-cured composite was compared with a light-cure composite (one trial), a conventional glass ionomer cement (GIC; one trial) and a polyacid-modified resin composite (compomer; one trial). The quality of the trial reports was generally poor.
Conclusions It is not possible to draw anything other than tentative conclusions from this systematic review of orthodontic adhesives, primarily because of the weakness in the design and reporting of existing trials. Therefore, at present there is no clear evidence with which to make a clinical decision on the type of orthodontic adhesive to use. A number of suggestions are made for methods of improving future research involving orthodontic adhesives.
