Predicting tooth wear using advanced scanning techniques

Prediction of the Tooth Wear Index Based on a Dataset of Dental Shapes:a Retrospective Study

Observational Hospices Civils de Lyon · NCT06681844

This study is testing a new scanning method to see if it can help predict tooth wear early on, so people can take better care of their teeth before serious damage happens.

What this trial studies

This observational study focuses on predicting tooth wear, which is the gradual loss of dental hard tissue due to various factors. It utilizes intraoral scanners to monitor changes in tooth shape, aiming for early detection of wear that is often overlooked until it becomes severe. The study employs a novel method called MEG-IsoQuad, which automates the remeshing process to enhance the reliability of statistical shape analysis for diagnosing tooth wear. By assessing avulsed teeth with a specific wear index, the study seeks to improve understanding and management of tooth wear.

Who should consider this trial

Good fit: Ideal candidates for this study are patients with avulsed mature incisors, canines, premolars, or molars that exhibit a tooth wear index between 0 and 3.

Not a fit: Patients with teeth that have a wear index over 3 or those with immature teeth or wisdom teeth will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to earlier detection and better management of tooth wear, ultimately improving patients' oral health and quality of life.

How similar studies have performed: While the use of statistical shape analysis in dentistry is emerging, this specific combination of automated remeshing and shape analysis is relatively novel and has not been extensively tested in prior studies.
