About this study
Official title: Evaluation of a 3D-Printed Extraoral Camera Assembly for Standardization of Dental Photography: Randomized Controlled Clinical Trial
This study evaluates whether a 3D-printed extraoral camera assembly can improve the reproducibility and dimensional consistency of dental photographs compared with conventional DSLR methods. By standardizing camera position, distance, and angle, the assembly provides a non-contact, operator-independent approach to ensure consistent image geometry, supporting more accurate clinical records, esthetic documentation, and digital analyses.

Questions about this trial
What is this clinical trial studying?
An observational study of Malnutrition, run by Cairo University.
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 3 inclusion and 3 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: opening soon, as of the sponsor's last update on 19 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
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?
This study is still under way. Results are not available in the source record yet.
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.
What does the primary outcome measure?
knowledge (time frame: 3 months). It is what the study was designed to measure, not a finding.
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 19 Mar 2026.
