Introduction: Orthodontic brackets are bonded with different types of adhesive materials and methods. Sometimes these brackets debond before the treatment is finished. Previous research has compared different methods but due to insufficient research no recommendation can be made as to which material and method is the best. This has led to the question: Which adhesive ensures that stainless steel orthodontic brackets don’t debond during treatment? Purpose: The research objective is to evaluate which adhesive can best be used to prevent orthodontic bracket debonding. As a result, orthodontic bracket debonding during treatment will decrease which will have the benefit of reducing treatment time and saving costs in orthodontic care. Material and Methods: The design is a retrospective patient-related comparative cohort study. In three different orthodontic practices using each a different adhesive (direct glass ionomer, direct composite and indirect composite) data was collected by evaluating 315 patient charts. The independent variables are; gender, age, first time debonded tooth and duration between placement of the stainless steel orthodontic bracket and debonding. Results: Glass ionomer attached brackets had significantly fewer debonding compared to the other adhesives. Both direct composite and indirect composite show a significant difference in the first debonding of stainless steel orthodontic brackets in the first six months compared to the period after. Gender and age have no influence. In the lateral parts in particular the first time debonding of brackets occurs. This is significant for bonding with indirect composite. In addition, the first debonding of brackets for each adhesive occurs most often in the mandible. For bonding with direct glass ionomer and indirect composite this difference is significant. Conclusion: Within the limitations of this retrospective cohort study, a significant difference was found between the different adhesive systems for securing orthodontic brackets. Glass ionomer as an adhesive gave a significantly lesser chance of debonding of the bracket during orthodontic treatment.
