This is a double-blind, randomized controlled clinical trial, four armed. There will be a random division into four groups using sealed envelopes. Each group will have at least 30 restorations, divide

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected to identify whether the effects of occlusal factors affect the clinical performance of restorations in non-carious cervical lesions, through clinical follow-ups based on the modified USPHS criteria, which will measure the following parameters of restorations: anatomical shape, surface roughness, marginal discoloration, retention, marginal adaptation, postoperative sensitivity, secondary caries and fracture. | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected to identify whether restorations in non-carious cervical lesions performed in conventional composite resin present the same clinical performance as those performed in fluid composite resin, through the parameters measured by the modified USPHS. | — |
