5 Year Follow up Analysis on the Speed of Progression of Tooth Wear Using 3D Subtraction
Study Details
Study Description
Brief Summary
Prospective observational study with 5-year follow up. 55 patients are included with moderate to severe tooth wear, whereby through informed consent the decision was taking to monitor the patients. At the baseline and the 5-year recall digital 3D scans will be made, which will be compared and subtracted.

Detailed Description
Prospective observational study with 5-year follow up. 55 patients are included with moderate to severe tooth wear, whereby through informed consent the decision was taking to monitor the patients. At the baseline and the 5-year recall digital 3D scans will be made, which will be compared and subtracted. Per tooth the loss of material is measured in maximum loss in height (µm) and volume (mm3) per year, using best fit alignment and 3D subtraction.
In a multivariate statistical model the loss of tooth material per tooth type will be tested against possible individual risk factors such as bruxism and reflux. An interim analysis will be performed to test the feasibility of the research.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Studie A ESO - monitoring Patients that present themselves at the clinic through referral from their dentist with tooth wear, who have no request for help, receive a non-restorative 'counseling & monitoring' strategy , in which appropriate preventive measures are recommended and wear and tear is monitored and recorded by periodically taking intra-oral photographs and 3D scans |
Outcome Measures
