Stress and Tooth Structure Loss in Dental Students.

Not yet recruiting

• Conditions: Tooth Wear

• Registration Number: NCT05791175
• Lead Sponsor: Technische Universität Dresden

Brief Summary

The study is designed as a pilot study. The primary objective of the current study is to collect data on the expression and progression of tooth structure loss in dental students under stressful conditions and different dietary habits using intraoral scanners (IOS). Stress levels will be evaluated using Percived Stress Scale (PSS-10). Eating habits will be queried using reflux and dietary questionnaires. The data obtained will later be used in the case-control design of a multicenter study on the same topic. Conducting the pilot study will allow for a critical evaluation of the study's design, participant retention rate, and recruitment process.

Detailed Description

The first scan (baseline: T0) is performed during the Dental Prosthetics I course, at the beginning of the 8th semester. Follow-up scans T1 and T2 are performed at the beginning of the 10th semester and after completion of the state examination. The scans are performed by a study doctor or doctoral student using a digital intraoral scanner (Trios, 3 Shape, Denmark). Accompanying the scanning process, study participants will be asked to complete a questionnaire regarding stress levels (PSS) and dietary habits. A medical history and dental findings are also collected. Each scan will take no longer than 10 minutes. The entire examination will take no longer than 45 minutes. The T0 and T1, T2 scans will be overlaid with evaluation software and compared in terms of tooth wear.
