About this study
Official title: A Comparison Of Dental Arch Analysis Using 3d Digital Scanning Versus Conventional Methods In Children(A Crossover Randomized Controlled Trial)
A crossover study will be conducted on 20 pediatric patients aged 7-11 years. For each participant, the upper and lower study models will be processed using two methods: the conventional method, which involves alginate impressions, and the digital method, which utilizes a 3D intraoral digital scanner (CEREC Omnicam scanner or equivalent). Measurements of arch length, arch width, and arch depth will be taken from both model types using the conventional method with a brass wire and a digital caliper. At the same time, in the scan cast, they will be calculated digitally by 3D shape software. Statistical analysis will be done to compare the results of both methods.

What is being measured
The primary outcome is the main question the study is designed to answer.
Subjective outcome
Patient acceptance will be recorded according to Modified Facial scale modified from the Maunuksela et al scale showing the 3 schematic faces representing: (A) satisfaction; (B) indifference; and (C) dissatisfaction, respectively.
Measured: 2 months
Objective Outcome (Measurement)
arch width (inter canine and intermolar width) measured in mm
Measured: 2 months
Patient acceptance
Frankl's behavior rating scale will be re-evaluated after each method used. Score 1-4. score 1=definitely positive, score 2=positive,score 3=negative,score 4=definitely negative.

The record lists 1 site in Egypt. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Subjective outcome (time frame: 2 months). The study lists 5 primary outcomes in all. 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 12 May 2026.
