Overview
Brief Summary
The overall objective of this clinical investigation is to evaluate the clinical safety and performance of the new flowable composite TM Flow for treatment of non-carious cervical lesions. Each participant receives two different fillings (test- and control material) in two different teeth. The fillings are assessed according to selected FDI criteria at baseline (7-10 days after filling placement) and after 1, 6, 12, 24, 36 and 60 months.

Outcomes
Primary Outcomes
Postoperative Hypersensitivity
Time Frame: 1 month
assessed by tests with thermal stimuli and occlusal forces (during biting) determined by VAS (Visual Analog Scale, 0 "No pain at all" - 10 "The worst pain imaginable") following the FDI criteria on a scale from 1 "very good" to 5 "unacceptable" FDI 1: no complaint FDI 2: minor complaint FDI 3: distinct pain FDI 4: persistent pain for prolonged period of time FDI 5: treatment unavoidable
Secondary Outcomes
- Evaluation of Functional (e.g. Fracture of the Material and Retention), Biological (e.g. Caries at Restoration Margins) and Aesthetic (e.g. Color Match) Properties of the Restorations(5 years)
