Background: The aim of this research is to evaluate cyclic (CSBS) and static shear bond strengths (SSBS) of metal orthodontic brackets bonded to composite laminates using different conditioning protocols.
Methods: A total of 80 direct nanofilled composite laminate veneers were prepared on permanent incisors and divided into four equal groups according to different surface treatments. In group 1, diamond bur was used.
The aim of the study was to compare the survival rate of orthodontic brackets over a 12-month period using amorphous calcium phosphate (ACP) bonding system with a conventional adhesive (CA). In 30 patients with a mean age of 15 years 7 months, one operator bonded 138 brackets with a split-mouth design, using a resin-based CA and ACP-containing adhesive. The survival rate of the brackets was estimated by Kaplan-Meier analysis.

- The study assessed how effective resin infiltration material is at masking white spot lesions (WSLs) after orthodontic bracket removal in 18 patients divided into two groups based on the severity of their lesions.
- Group 1 had visible WSLs without surface disruption, while Group 2 had roughened surfaces but did not need restoration.
- Results showed a significant improvement in masking WSLs for both groups after applying the resin, with a statistical significance of P<0.05, indicating the treatment was effective.
