Effect of One-step Versus Multistep Polishing Protocol on Class IV Composite Restorations.
Egypt50 participantsStarted 2025-08-01
Plain-language summary
This study aims to evaluate the effectiveness of various finishing and polishing techniques for composite resins used in dental restorations, with a focus on minimizing discoloration and surface roughness over time. Discoloration due to plaque accumulation and surface staining can lead to esthetic concerns, resulting in premature restoration replacement and increased costs. Prior research highlights that esthetic failures, such as color alterations and surface staining, are key reasons for the failure of anterior restorations. Given the contradictory findings in previous studies on finishing and polishing methods, this research seeks to determine whether one-step polishing system will have the same effect as the multistep system in terms of esthetic performance and surface roughness of nanohybrid resin composite class IV restorations. The main operator will compare between OneGloss (Shofu) the intervention and Super-Snap X-treme (Shofu) the comparator. Patients will be evaluated immediately following polishing then after 3 months, 6 months, and 12 months.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
