Tooth Discoloration and Chairside Handling Time (Bonding-Debonding) in Flowable Versus Packable Composites for Clear Aligner Bonded Attachments: A Randomized Clinical Trial

This randomized split-mouth clinical trial aims to compare two different composite materials used for bonding attachments in clear aligner orthodontic therapy. Twenty adult participants with Class I malocclusion and mild crowding will receive flowable nanocomposite attachments on one side of the dental arch and packable microhybrid composite attachments on the opposite side. The primary outcome is the color change (ΔE) of the enamel surface after attachment removal, measured by a spectrophotometer (VITA Easyshade). Secondary outcomes include bonding and debonding time and changes in enamel surface roughness before and after treatment. The study will be conducted at the Orthodontic Department, College of Dentistry, University of Sulaimani. The goal is to determine which composite material provides better color stability, easier handling, and minimal impact on enamel surface characteristics during clear aligner therapy.
