Evaluation of Intraoral Scanning vs Conventional Impression in Assessing Dental Crowding
Evaluation of Intraoral Scanning Versus Conventional Impression in Assessing Dental Crowding Among a Group of Egyptian Children: A Cross Sectional Study
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.

Detailed Description
Dental crowding is one of the most common malocclusions observed in pediatric dentistry, requiring precise diagnostic models for accurate treatment planning and space analysis. Traditional alginate impression procedures often cause discomfort, gag reflexes, and anxiety in pediatric patients. The emergence of intraoral digital scanners (IOS) provides a 3D digital approach that enhances patient acceptance and streamlines diagnostic workflows.
In this cross-sectional study, eligible Egyptian children presenting with dental crowding will undergo both intraoral digital scanning and conventional impression procedures. Dental arch measurements, space analysis, and crowding severity will be assessed using both methods to evaluate agreement, effectiveness, procedure duration, and patient acceptance. The study aims to contribute clinical data on the application and feasibility of digital workflow technologies in pediatric dentistry in Egypt.

Sampling Method
Study Population
Pediatric patients attending the outpatient clinics who require space analysis and evaluation for dental crowding.
Description
Inclusion Criteria:
- Egyptian children aged 11-13 years
- 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
- Fully erupted permanent teeth (first molar to first molar)
- No previous orthodontic treatment
Exclusion Criteria:
- Craniofacial anomalies
- Missing or grossly restored teeth
- Uncooperative behavior
