Trial Title: NCCL Direct Composite Restoration Performance With Self-Etch and Multimode Adhesives

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: FACTORIAL
- Observational Model: None
- Primary Purpose: OTHER
- Time Perspective: None
- Masking: TRIPLE
- Phase: None
- Number of Arms: 6.0

Eligibility Criteria:
Inclusion Criteria:~* Patients of both genders~* ages up to 18 years old and less than 65 years old~* Patients with diagnosis and treatment required of dental structure loss in cervical vestibular surfaces with non-bacterial or chemical origin, which is non-carious cervical lesions (NCCL) in premolar/molar teeth (These lesions have to be non-carious, non-retentive, deeper than 1 mm, and involve both the enamel and dentin of vital teeth without mobility. The cavo-surface margin cannot involve more that 50% of enamel.)~Exclusion Criteria:~* Patients with a number of teeth inferior than 20 in occlusion;~* If the tooth is not vital;~* Chronic periodontal disease;~* Incapacity to return to follow-up;~* To participate in another clinical evaluation in course at that time;~* Medical, psychiatric history or pharmacotherapy to compromise the protocol~* Pregnancy;~* Allergies and idiosyncratic answers to the ingredients of the products;~* Fixed orthodontic treatment;~* Teeth support for fixed prosthodontic treatments;~* Teeth or structures of support with pulpa injury in transition phase;~* Periodontal surgery in the 3 previous months;~* Severe bruxism;~* Extremely poor oral hygiene;~* Patient refuse to voluntary participate in the trial.

Study Arms:
- FBDC-SE (G1; Control) (Type: ACTIVE_COMPARATOR): Futurabond DC (single dose blister) will be applied as thickness to the enamel/dentine and rub into the tooth surface for 20s; FBDC drying layer for at least 5s with an air syringe; This adhesive layer will be light-cured with a light emitting diode unit (LED light), with an intensity of 1000mW/cm2, during 20s.
- FBDC-SE-EE (G2; Control ) (Type: ACTIVE_COMPARATOR): Etch with 36% phosphoric acid, during 30s in enamel structures. Remove the 36% phosphoric acid with water during 1 minute. The remove of water excess will be done with weak air spray, not to dry the dentine completely. The dentine surface must slightly remain wet. Application of Futurabond DC (FBDC) as self-etch mode simultaneously in dentin and enamel, and the light-cured (LED light; 1000mW/cm2), during 20s.
- FBU-ER (G3) (Type: OTHER): FuturabondU® (FBU) apply in enamel and dentin as etch-and-rinse (ER) mode. Etching of the dental hard tissue phosphoric acid (15s in dentin and 30s in enamel) and then rinse with water for 1 min. Dry off excess moisture with a gentle stream of air. Activating FBU SingleDose. FBU adhesive will be homogeneously applied to all cavity surfaces and rub in for 20s using the Single Tim; This adhesive layer will be light-cured with a light emitting diode unit, with an intensity of 1000mW/cm2 during 20s.
- FBU-SE (G4) (Type: OTHER): FuturabondU® (FBU) apply in enamel and dentin as SE mode. Activating FBU SingleDose. FBU adhesive will be homogeneously apply to all cavity surfaces and rub in for 20 s using the Single Tim; Dry off the adhesive layer with dry, oil-free air for at least 5 s in order to remove any solvents. This adhesive layer will be light-cured with a light emitting diode unit (LED light), with an intensity of 1000mW/cm2, during 20 seconds.
- ADU-ER (G5) (Type: OTHER): Adhese®Universal (ADU) apply by etch-and-rinse (ER) mode. Etching of the dental hard tissue phosphoric acid (15 seconds in dentin and 30 seconds in enamel); Etch agent rinse with water for 1 minute. Dry off excess moisture with a gentle stream of air. Keep dentin dry, do not over dry; Adhesive ADU will be scrubbed into the tooth surface (enamel and dentin) for at least 20 seconds. Adhesive will be dispersed with compressed air until a glossy, immobile film layer results.Light-curing for 10 s with a light emitting diode unit (LED light), with an intensity of 1000mW/cm2 for 20s.
- ADU-SE (G6) (Type: OTHER): Adhese®Universal (ADU)apply by self-etch (SE) mode. Starting with the enamel, thoroughly coat the tooth surfaces (enamel and dentin) to be treated with ADU; Adhesive will be scrubbed into the tooth surface for at least 20 seconds. Adhesive will be dispersed with compressed air until a glossy, immobile film layer results.Light-curing for 20 s with a light emitting diode unit (LED light), with an intensity of 1000mW/cm2.
