A glass hybrid restorative system (EQUIA forte) clinically compared to a composite resin based material (Clearfil SE Bond, Filtek Supreme XT) for the treatment of dental non-carious cervical lesions.

This is a prospective, randomized, monocenter parallel group study on restoration of tooth with non-carious cervical restorations. Each patient receives cervical restoration(s) either with glass hybrid EQUIA forte or with composite resin/adhesive combination Filtek Supreme XT/Clearfil SE Bond in anterior/posterior tooth region. Restorations will be provided by one experienced operator. One of two independent examiners will evaluate the restorations at baseline (1 week after placement), and after 18, and 36 months according to the FDI criteria. Reliability of examination will be assessed on a random sample of 30 restorations.

Inclusion Criteria:

• indication of a restorative treatment for a sclerotic non-carious cervical lesion
• lesions should be accessible for treatment and visual-tactile re-evaluation
• sufficient moisture control should be possible
• cervical margins should be located in dentin whereas the coronal margin should be located in enamel

Exclusion Criteria:

• allergy/hypersensitivity against any of the used materials
• participants should not be systematically ill, disabled, pregnant or participating in another study
