Eligibility
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: Volunteers at least 18 years of age; both genders; in good general health; with at least 4 teeth (premolars or molars) with non-carious cervical lesions with a depth and extension of at least 1 mm, vital and without mobility; with at least 20 teeth in occlusion

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected to find differences between the restoration retention parameter. To assess retention, the FDI (World Dental Federation) criteria will be used, where restorations will be classified into scores from 1 to 5, with criterion 1 being restorations without loss of retention; 2 with small crack line; 3 with two or more lines of cracks and/or small chips or fracture of the material without affecting the marginal integrity; 4 with partial loss of material (less than half of the restoration); 5 with partial or complete loss of restoration | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected to find differences between the staining parameter of the restoration. To evaluate, the FDI (World Dental Federation) criteria will be used, where restorations will be classified into scores from 1 to 5, with criterion 1 being for restorations without staining; 2 with small staining; 3 with moderate staining; 4 unacceptable staining; 5 Severe staining;It is expected to find differences between the marginal adaptation parameter of the restoration. To assess, the FDI (World Dental Federation) criteria will be used, where restorations will be classified into scores from 1 to 5, with criterion 1 being for harmonious restorations without cracks; 2 with white lines; 3 with cracks and small fractures; 4 major irregularities; 5 larger cracks or generalized irregularities;It is expected to find differences between the postoperative sensitivity parameter of the restoration. For evaluation, the FDI (World Dental Federation) criteria will be used, where restorations will be classified into scores from 1 to 5, with criterion 1 being for restorations without sensitivity; 2 with low sensitivity for a short time; 3 with more intense sensitivity; 4 very intense; 5 acute pulpitis;It is expected to find differences between the lesion recurrence parameter. For evaluation, the FDI (World Dental Federation) criteria will be used, where restorations will be classified into scores from 1 to 5, with criterion 1 being for restorations without recurrence; 2 with small, localized lesion; 3 with larger areas of demineralization; 4 dentin erosion; 5 exposure of dentin that requires replacement of the restoration | — |
