Parent Satisfaction With Zirconia, Bioflx, and 3D-Printed Crowns for Primary Molars
Egypt90 participantsStarted 2026-04-01
Plain-language summary
This study will compare parent satisfaction with three different types of dental crowns used to restore primary (baby) molars in children: zirconia crowns, Bioflx crowns, and 3D-printed crowns.
Children between 3 and 7 years of age who need a full-coverage restoration of a primary molar will be invited to participate. Participants will be randomly assigned to receive one of the three crown types. All crowns will be placed by the same dentist using standardized treatment procedures.
After treatment, parents will be asked to complete a questionnaire about their satisfaction with the crown. The questionnaire will evaluate several aspects, including the crown's appearance, size, shape, color, durability, and overall satisfaction. Parent satisfaction will be assessed immediately after crown placement and again one month later.
The purpose of this study is to determine whether there are differences in parent satisfaction among these three crown options. The results may help dentists and families make informed decisions when choosing esthetic full-coverage restorations for primary teeth.

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.
