Do upper and lower front teeth follow a size rule? a digital model study aims to find out
NCT ID NCT07734571
First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time
Summary
This pilot study investigates whether the widths of the upper and lower front teeth are correlated in Egyptian adults with normal tooth size. Researchers will use intraoral scanners to create digital models and measure each tooth's width. The goal is to identify a predictable relationship that could guide dentists in creating balanced, natural-looking smiles.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If a consistent ratio is found, it could help dentists design more natural-looking smiles for Egyptian patients.
- What could go wrong
- This is a small pilot study in one population, so findings may not apply broadly. The study only measures tooth widths and does not test any treatment.
