Dentin Treatments for Restorations of Cervical Lesions Non-Carious
28 participantsStarted 2011-03
Plain-language summary
The surface of non-carious cervical lesions (LCNC) is a challenge to adhesive systems, it presents a dentin layer sclera hypermineralized, presence of bacteria and lack of mechanical retention, so this study aimed to evaluate the influence of different surface treatments on LCNC through a randomized clinical trial. Patients with LCNC were referred to the study and selected according to the inclusion criteria, such as the presence of at least 3 LCNC. Three different types of surface treatment were carried out in LCNC: control group, 15 seconds of etching dentin; Group I, acid etching of dentin in 30 seconds; and group II, cavity prophylaxis with ultrasound for 30 seconds. The remaining steps of the adhesive and restorative procedure was the same for all groups, following the material manufacturer's recommendations. Evaluations of restorations will be carried out in periods of one week (baseline), six months, one year, two years and three years as of tooth sensitivity, integrity and color change. Data will be analyzed by McNemar and chi-square test.

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?
