Abstract

Adhesive precoated brackets in orthodontics have been used over the last 20 years. This technique has been played as the topic of numerous studies with good support deeming it ready to assess their properties compared to conventional brackets. In this systematic review, we compared the differences of shear bond strength between precoated and uncoated brackets. Electronic databases (The PubMed, Scopus, Springer, Cochrane library, and Web of Science) were explored without language restriction. The correlated orthodontic articles and reference records were confirmed for all eligible studies. Two journal reviewers individually retrieved the data and evaluated the quality of the primary studies. A total of 152 articles were extracted in the initial search. However, only 15 articles met the inclusion criteria. Outcomes of shear bond strength between two systems of bracket were similar. The result was inconclusive, precoated bracket was not proven to be superior to the conventional bracket. There is no clinical agreement that can be made concerning the type of bracket systems.
