Background: Cervical lesions appear on the cervical surface of the lingual or buccal side of the tooth and are classified into carious and non-carious lesions.
Aim: The present study evaluates the performance of three different types of aesthetic restorative materials, used for the restoration of carious or non-carious cervical lesions.
Materials and methods: The study comprised 195 cervical lesions in 45 patients. The restorations were carried out for non-carious cervical lesions in 34.62% of the cases, for primary carious lesions in 40.00% of the cases, and to replace a previous restoration in 25.38% of the cases. The restorations were evaluated at 2 weeks (the reference line), and then at 1 and 2 years after placement. The following have been assessed: restoration retention, color harmonization, surface texture, margin discoloration, anatomical contour, margin integrity, and the presence of secondary caries. The characteristics were registered in conformity with the modified USPHS criteria.
Results: At the one-year evaluation, we noticed the loss of 12 restorations, and after 2 years, the loss of 19 restorations. The results showed significant differences between restorative materials regarding color, margin adaptation, margin coloration, surface texture, as well as criteria regarding the anatomical contour (p <0.05).
Conclusions: The evaluation of the success of restorative material retention must consider the location of the cervical lesion. A successful treatment depends particularly on a full understanding of the factors that caused the lesions and on the method of their treatment.
