AI-assisted measurement of gummy smiles from photos

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational pilot tests an AI tool for diagnosing and measuring gummy smiles using patient photographs. The AI is trained on a set of images and then evaluated on a new set to compare its measurements with those from experienced periodontists, who serve as the reference standard. The study aims to determine if the AI can provide fast, consistent measurements that align with expert assessments in Cairo University clinics. It focuses on diagnostic accuracy rather than treatment effects. No interventions are being tested beyond data annotation and AI evaluation.
