Conditions

Non-carious Cervical Lesions

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.

Interventions

DEVICERestoration of non-carious cervical lesions

Non-carious cervical lesions will be treated with the experimental TM Flow or the well-established Tetric EvoFlow. The treatment workflow is very similar to other flowable composites.

Inclusion criteria

* Informed Consent signed by the subject * Age: 18-65 years * 2 NCCL needing treatment, comparable in extend and size, preferably located in different quadrants * Vital teeth, regular sensitivity * Sufficient language skills * No active periodontitis * Preoperative VAS values \< 3 regarding tooth sensitivity on biting. Tooth sensitivity on temperature or touching (tooth brushing, probing) originating in the area of the NCCL is accepted. * Subject wishes to have a restoration as part of the study (written declaration of consent after detailed explanation)

Exclusion criteria

* Not completed hygiene phase or poor oral hygiene * Sufficient isolation of the cavity not possible * Patients with a proven allergy to one of the ingredients (methacrylates) * Patients with severe systemic diseases * Periodontally insufficient dentition * Pregnancy * Part of the development project team of TM Flow * Staff of the study management team * Staff of the internal clinic
