Conditions
Interventions
Forty- five subjects with at least five non-carious cervical lesions are selected. In each individual, the teeth will be randomly divided into 5 groups and given the following treatments:
1) a conven
2) A 2% proanthocyanidin solution (PA) will be applied to the dentin before to application of adhesive (even in the control group
)3) A 5% PA solution will be applied to the dentin before to application of the adhesive (even in the control group)
4 ) PA is included in the commercial adhesive system at a concentration of 2% and will be applied to the dentin 5) PA is included in the commercial adhesive system at a concentration of 5 % and will

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Retention: Evaluation through visual inspection with explorer and mirror in periods of 6, 12, 18, 24 months. Will be classified as: retained ou missing. | — |
Secondary
| Measure | Time frame |
|---|---|
| Marginal adaptation: Evaluation through visual inspection with explorer and mirror, if necessary, in periods of 6, 12, 18, 24 months. Will be classified as: Restoration is continuous with existing anatomic form, detectable V-shaped defect in enamel only (catches explorer going both ways) or detectable V-shaped defect to dentinenamel junction Marginal staining: Evaluation through visual inspection with mirror, in periods of 6, 12, 18, 24 months. Will be classified as: no discoloration along the shore, light and superficial staining (removable and usually located) or deep pigmentation that can not be removed by polishing Secondary caries: Evaluation through visual inspection with mirror and explorer, in periods of 6, 12, 18, 24 months. It will be classified as: No evidence of caries contiguous with the margin or evidence of the presence of caries. Postoperative Sensitivity Evaluation by an air jet directed on the restoration at a distance of 3 cm from the tooth surface for 5 seconds, in periods of 6, 12, 18, 24 months. It will be classified as: without postoperative sensitivity immediately after the restorative process and during the study period and this sensitivity at any time during the study period | — |
