Comparing Color Stability and Bonding Time Between Flowable Nanocomposite and Packable Microhybrid Composite in Clear Aligner Attachments A Randomized Split-Mouth Clinical Trial in Adults with Class I Malocclusion

What this Trial Is About

Researchers are evaluating two types of composite materials used for bonding attachments in clear aligner orthodontic treatment. This randomized split-mouth clinical trial involves twenty adults aged 18 to 40 with Class I malocclusion and mild crowding. The study aims to compare the color stability, bonding and debonding times, and effects on enamel surface roughness of flowable nanocomposite versus packable microhybrid composite materials used for these attachments. The trial is conducted at the Orthodontic Department, College of Dentistry, University of Sulaimani. Participants will receive flowable nanocomposite attachments on one side of the dental arch and packable microhybrid composite attachments on the opposite side. The study will measure enamel color change using a spectrophotometer before bonding and after attachment removal. Bonding and debonding times will also be recorded, along with enamel surface roughness assessed through digital and optical analysis techniques. During the study, participants will undergo color shade measurements, photographs or scans, and assessments of pain or discomfort using a visual analog scale. Researchers will monitor oral hygiene and gingival health to ensure suitability for participation. Follow-up visits will track changes and assess outcomes related to enamel color, handling time of materials, and surface roughness throughout clear aligner therapy.
