Background and Objectives: A relatively new light-cure orthodontic adhesive BracePaste® can fluoresce under UV light to assist in cleaning up excess flash after bonding. Complete removal of excess resins around the bonded brackets may minimize excessive loss of enamel upon debonding. The objective of this study was to determine the shear bond strength of BracePaste compared to that of the conventional “Transbond XT” adhesive. Additionally, enamel and bracket interfaces were examined to determine the location of bond failure and the tooth surfaces were visually examined to assess severity of enamel marks and the presence of remaining adhesives on the …

Graduate Theses, Dissertations, and Problem Reports
Objective: The objective is to determine if there is a significant difference in shear bond strength and debonding characteristics between one-piece metal brackets made by metal injection molding (MIM) and multi-piece metal brackets made by machining then soldering/brazing with differing pad designs. Methods: A total of thirteen metal orthodontic brackets manufactured by 8 different companies were divided into two groups: one-piece MIM and multi-piece brackets. Each group consisted of 10 brackets for a total of 130 brackets. Brackets were bonded to stainless steel tubes with a universal bonding technique. Samples were tested on the universal Instron testing machine to measure …
