An observational study of Dental Prosthesis Failure, run by Heidelberg University at 1 site in Germany.
Trial summary
The purpose of this study is to compare three different core build-up materials for dental use. The study hypothesis is that there is no differences in survival rate of the different core build-ups. Read more about this study

About this study
Official title: Core Build-up Materials: a Randomized Clinical Study
The purpose of this study is to compare three different core build-up materials for dental use. The study hypothesis is that there is no differences in survival rate of the different core build-ups.
Read the detailed description
Core build-ups replace dental structures which are decayed through caries or tooth fractures. Often there are necessary before insertion of dental restorations. In clinical practice, there are two main material groups: glass ionomer cements and composites. Because of there good physical properties the composite materials claimed to fulfill the expected criteria of core build-ups. However, some of these composite core build-ups get lost before insertion of definite prosthetic restorations. The current prospective, randomized controlled study should investigate the survival rate of three different composite materials: "Rebilda DC", "Clearfil Core DC / Plus" and "Multicore Flow". The statistical analysis will performed with logistic regression performed by the institute of institute of Medical Biometry and Informatics, university of heidelberg. The study hypothesis is that there is no differences in the survival rate.

Questions about this trial
What is this clinical trial studying?
An observational study of Dental Prosthesis Failure, run by Heidelberg University at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2018; AzTrials last refreshed its copy on 6 Nov 2026.
