About the research

The purpose of this study is to evaluate and compare the effectiveness and efficiency of Intraoral Scanning (IOS) versus conventional impressions in assessing dental crowding among a group of Egyptian children. Accurate space analysis and crowding assessment are essential for pediatric orthodontic planning. Intraoral scanners offer a digital alternative that may improve patient comfort and reduce procedure time compared to traditional alginate impressions. This observational cross-sectional study aims to provide clinical evidence regarding the validity of digital impression techniques in pediatric dental settings.

Who may be able to participate?

The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.

Inclusion Criteria:

1. Egyptian children aged 11-13 years
2. Dental crowding ≥ 2 mm in at least one arch, determined by space analysis (arch length discrepancy). Crowding will be calculated as the difference between the sum of mesiodistal tooth widths and the available arch perimeter measured on the diagnostic cast. A discrepancy ≥ 2 mm will be considered clinically significant
3. Fully erupted permanent teeth (first molar to first molar)
4. No previous orthodontic treatment

Exclusion Criteria:

1. Craniofacial anomalies
2. Missing or grossly restored teeth
3. Uncooperative behavior

Study population

Pediatric patients attending the outpatient clinics who require space analysis and evaluation for dental crowding.

Treatment, groups and participation

The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.
