Shade Matching of Omnichroma (One Shade Universal Composite) Versus a Microhybrid Composite in Class V Restorations.

Plain-language summary

Background Resin composites are effective in restoring damaged teeth due to their good esthetics, high surface gloss, and clinically acceptable wear resistance1. One of the most challenging tasks a dentist has to confront in daily practice is matching the color of composite restorations used in anterior teeth2. Problem The shade selection is carried out subjectively with a visual shade guide and generally under inadequate light conditions, which can lead to errors in color perception3. The presence of discrepancies between the classic shade guides and the actual shade of composite makes that task more difficult.4. Not only that, but there was also mismatch between composite shades and the proprietary shade guides included with the composite kits 5. A mock-up should be performed as a trial to assist in shade selection and ensure the predictability of the esthetic result in restorative treatment6. Rationale Shade matching has been a time consuming procedure. Recommendations were made to make customized shade guides of the used composite material for more predictable results7. Manufacturers have been aiming at providing materials with a blending effect; taking on the color appearance from surrounding tooth structure 8. Introduction of Omnichroma by Tokuyama is aiming at eliminating the shade taking procedure by providing a single shade universal composite that is designed to blend with the surrounding tooth structure without the need for a shade matching procedure. Aim The aim of this study is to evaluate the shade matching ability of a new single shade composite (Omnichroma; Tokuyama) compared to a conventional multiple shade microhybrid composite in the restoration of class V restorations using USPHS criteria

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?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

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.
