Brief Summary

Treatment clinical trial, randomized, controled, parallel, double-blinded, with four groups, that aims to evaluate the best application strategy when using a new Universal Adhesive system, Ambar Universal (FGM, Joinville, Brazil). Volunteers will be selected and recruited,following inclusion criteria and pre-established exclusion. All volunteers will be informed and sign a term of clarification and consent. 38 enrolled patients will receive four Class V dental restorations, made in four different ways, one from each experimental group, using the same universal self-etching adhesive system, which is the tested material in this study. Non-carious cervical lesions will receive the applied adhesive system in 4 different protocols separated by groups. Group Self Etching (SET) (control): no conditioning, the adhesive system will be used in 55 teeth, according to the manufacturer's instructions, in the self-etching mode. The adhesive system will be brushed during 10 seconds in the cavity, will be air-dried during 5 seconds, brushed again during 10 seconds, air-dried during 10 seconds and activated during 10 seconds with Light Emission Diode (LED) light; Group SEE (Selective enamel etching): 37% phosphoric acid will be applied during 15 seconds, only in enamel in 55 teeth. This acid will be removed using water, the cavity will be air-dried, and then, the adhesive will be applied according to the manufacturer's instructions, as described in group SET; Group SETT (Self-Etching with extended time): Similar to Group SET, but during the 2 applications, the adhesive systems will be brushed during 20 seconds, and not during 10 seconds as described in Group SET; Group SETL (Self-Etching with extended number of layers): The adhesive system will be applied as describe in Group SET, but the researchers will apply 4 layers, and not 2 layers, as described in Group SET. After applying the adhesive, the restorations will be made with composite resin, and evaluated every 6 months for pain assessment, shape, staining or recurrent caries, using scores. To determine in which group each tooth will be enrolled, the authors will randomize the teeth.

Interventions

Self-Etching Application Strategy OTHER

In Group SET, the adhesive system Ambar Universal will be used in 55 teeth, according to the manufacturer's instructions, in the self-etching mode. The adhesive system will be brushed during 10 seconds in the cavity, will be air-dried during 5 seconds, brushed again during 10 seconds, air-dried during 10 seconds and activated during 10 seconds with LED light; After applying the adhesive, the restorations will be made with composite resin Opallis (FGM, Joinville, Brazil), and evaluated every 6 months for pain assessment, shape, staining or recurrent caries, using scores.

SET (Self-Etching)

Enamel Etching Application Strategy OTHER

In Group SEE, 37% phosphoric acid will be applied during 15 seconds, only in enamel in 55 teeth. This acid will be removed using water, the cavity will be air-dried, and then, the adhesive system Ambar Universal will be brushed during 10 seconds in the cavity, will be air-dried during 5 seconds, brushed again during 10 seconds, air-dried during 10 seconds and activated during 10 seconds with LED light; After applying the adhesive, the restorations will be made with composite resin Opallis (FGM, Joinville, Brazil), and evaluated every 6 months for pain assessment, shape, staining or recurrent caries, using scores.

SEE (Selective Enamel Etching)

Self Etching with Extended time Application Strategy OTHER

In Group SETT, the adhesive system Ambar Universal will be used in 55 teeth, in the self-etching mode. The adhesive system will be brushed during 20 seconds in the cavity, will be air-dried during 5 seconds, brushed again during 20 seconds, air-dried during 10 seconds and activated during 10 seconds with LED light; After applying the adhesive, the restorations will be made with composite resin Opallis (FGM, Joinville, Brazil), and evaluated every 6 months for pain assessment, shape, staining or recurrent caries, using scores

SETT (Self-Etching, more time)

Self Etching with Extended layers number Strategy OTHER

In Group SETL, the adhesive system Ambar Universal will be used in 55 teeth, in the self-etching mode. The adhesive system will be brushed during 10 seconds in the cavity, will be air-dried during 5 seconds, brushed again during 10 seconds, air-dried during 5 seconds, brushed again during 10 seconds, air-dried during 5 seconds, brushed again during 10 seconds, air-dried during 5 seconds, and activated during 10 seconds with LED light; After applying the adhesive, the restorations will be made with composite resin Opallis (FGM, Joinville, Brazil), and evaluated every 6 months for pain assessment, shape, staining or recurrent caries, using scores
