Plain-language summary
Aim of the study :
to compare between 3D printed microfilled hybrid composite endocrowns and prefabricated zirconia crowns for restoring pulpally treated primary molars regarding the following aspects: In Vivo aspects Patient satisfaction
\*The esthetic, functional and biological performance according to FDI clinical criteria. At 3, 6 and 12 months
In Vitro aspects:
* Marginal gap.
* Fracture resistance.
Study methodology:
This study is a combined randomized clinical trial and in vitro study .The study will be conducted at the Department of Pediatric Dentistry and Dental Public Health, Faculty of Dentistry,
Ain Shams University as follows:
In vivo comparison of the clinical performance of 3D printed Endocrowns versus prefabricated zirconia crowns regarding esthetic, functional and biological performance according to FDI clinical criteria. In vitro evaluation of the marginal gap and fracture resistance of both types of restorations.

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.
