Abstract: Introduction: Orthodontic treatments commonly involve the attachment of brackets to teeth, which play a key role in tooth movement and alignment. After completing the treatment, the brackets are removed , leaves behind residual adhesive on the enamel surface. The removal of this residual adhesive is a crucial aspect of post-orthodontic care. Improper or aggressive adhesive removal can lead to damage to the enamel, resulting in increased surface roughness, aesthetic compromise, and a higher risk for plaque accumulation, staining, and other dental issues such as caries. Therefore, the ideal method for removing this residual adhesive should be both efficient and gentle enough to minimize enamel damage, preserving the tooth's natural smoothness.The primary objective of this study is to evaluate and compare the enamel surface roughness after orthodontic bracket debonding using different systems for residual adhesive removal. The goal is to determine which adhesive removal technique is most effective at cleaning the enamel surface while causing minimal damage. Additionally, the study aims to assess the time efficiency of each method and its practical implications for clinical settings. Methods: This study was conducted in vitro, using 51 extracted human premolar teeth, free from cracks, fractures, or carious lesions. The teeth were cleaned before the experiment and divided into five groups, each subjected to a different method for adhesive removal after bracket debonding.The five adhesive removal systems tested are:Tungsten Carbide Burs : G1,Enhance Polishing Points: G2,Fiberglass Bur: G3,DU10CA-Ortho Disc: G4,Sof-Lex Pop-On Polishing Disc: G5.The experiment will simulate realistic conditions by bonding standard edgewise metal brackets to each tooth using light-cured orthodontic adhesive. After a 7-day storage period in distilled water at 37°C, the brackets will be debonded using standard pliers, leaving residual adhesive on the enamel. Each group will undergo adhesive removal using one of the five systems.Enamel surface roughness will be assessed using Scanning Electron Microscopy (SEM) at magnifications of 1000x, 2000x, 8000x, and 60000x. The time taken for complete adhesive removal will also be recorded using a stopwatch to compare the efficiency of each method. The roughness will be quantified using a surface roughness tester, with the Roughness value used to analyse and compare the results. Result The results will provide valuable data on the effectiveness of each adhesive removal method in terms of enamel surface roughness and time efficiency. The study will quantify surface roughness to determine which method minimizes enamel damage while effectively removing residual adhesive. Additionally, the time taken for each method to achieve complete adhesive removal will be compared, offering insights into the practicality and efficiency of each system. Conclusion: This study will contribute to improving post-orthodontic care by evaluating five different adhesive removal methods and their impact on enamel integrity. The results will provide insights into the optimal balance between efficient adhesive removal and enamel preservation, leading to better long-term dental health for patients and minimizing the risk of future dental complications.
