Effect of Silane Coupling on the Clinical Performance of Repaired Composite

Jordan43 participantsStarted 2022-03-10

Plain-language summary

Research Problem : Advances in adhesive technologies have introduced several surface treatment concepts that enable the clinician to adhere resin-based composite restorations onto new composite materials. The service life of faulty direct composite restorations can be prolonged by composite repair wherein durable adhesion between old and new resin-based composite materials is established.

Inclusion Criteria: * Deciduous tooth * Sustained dentin hypersensitivity * Irreversible pulpitis , necrotic, or inadequately-treated endodontic teeth * Grossly defective composite restorations that were indicated for replacement. * Teeth with compromised periodontal status. * Patients with poor oral hygiene Exclusion Criteria: * Patients older than 18 years. * Asymptomatic restored premolars or molars. * Vital or endodontically treated teeth * Patients with localized, marginal, anatomical deficiencies and/or carious lesions adjacent to composite restorations or esthetically unpleasant restorations. * Teeth with marginal gingivitis but healthy periodontium. * Tooth in normal occlusion with antagonist and at least one adjacent tooth.

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.

What they're measuring

Assessment of the quality of the repaired restoration retention, colour match, marginal discoloration, marginal adaptation, anatomical form and surface roughness.
