Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are individuals aged 12 years or older with no maxillary anterior tooth loss.
✕Probably not a fit
Patients with missing anterior maxillary teeth, significant anatomical pathologies, or factors that interfere with their smile may not benefit from this study.

What this trial studies
This study focuses on developing an AI-supported model to objectively evaluate gummy smiles, which are characterized by excessive gum visibility when smiling. By utilizing a unique dataset of images obtained through standardized clinical protocols, the study aims to provide a reproducible analysis that considers both aesthetic and periodontal health perspectives. The model will be trained on images labeled by an expert, addressing the limitations of current subjective evaluation methods in dental practice.
Why it matters
Potential benefit: If successful, this study could lead to more accurate assessments of gummy smiles, improving patient communication and treatment planning.
How similar studies have gone: While the use of AI in dental image analysis is emerging, this specific approach to gummy smile segmentation is relatively novel and has not been extensively tested in prior studies.
