Summary

To evaluate the clinical performance of the restorations by applying the universal adhesive in different modes under the influence of different surface treatments, with Erbium Chromium:Yttrium-Scandium-Gallium-Garnet (Er,Cr:YSGG) laser and acid etching in non-carious cervical lesions.

Detailed description

Forty-one patients (at least five non-carious cervical lesions) have participated in this study. The non-carious cervical lesions in each patient were divided into five groups (total-etch mode with phosphoric acid, selective-etch mode with phosphoric acid, total-etch mode with laser, selective-etch mode with laser and self-etch mode) according to different modes and application methods of universal adhesive (Clearfil Universal Bond Quick, Kuraray). Lesions were restored with a resin composite, Clearfil Majesty ES-2 (Kuraray). All restorative procedures were performed by a single operator. Restorations were evaluated at one week (baseline), at 6-, 12-, 18- and 24-month according to modified USPHS criteria (retention, marginal discoloration, marginal adaptation, color match, postoperative sensitivity, and secondary caries) by two experienced and calibrated investigators.

Interventions

Type	Name	Description
PROCEDURE	Total-etch mode with 35% phosphoric acid (K-ETCHANT) (TE-A group)	35% phosphoric acid was applied to enamel and dentin for 10 s, washed and dried for 5 s. The universal adhesive, Clearfil Universal Bond Quick (CBQ) was applied to enamel and dentin surfaces with a single-use applicator, then gently air-dried for 5 s without waiting, and light-cured for 10 s.
PROCEDURE	Selective-etch mode with 35% phosphoric acid (K-ETCHANT) (SE-A group)	35% phosphoric acid was used only on enamel for 10 s, then washed and dried for 5 seconds. Subsequently, the adhesive was applied in a similar manner to the TE-A group.
PROCEDURE	Total-etch mode with Er, Cr: YSGG laser (Waterlase MD) (TE-L group)	the enamel margin and dentin surfaces of lesions were irradiated with an Er,Cr:YSGG laser (2780 nm, Waterlase MD, BioLase Technology, Inc., San Clemente, CA). Then the adhesive was applied in a similar manner to the TE-A group.
PROCEDURE	Selective-etch mode with Er, Cr: YSGG laser (Waterlase MD) (SE-L group).	The laser system was applied in the same way as described in the TE-L group only on enamel surface. Subsequently, the adhesive was applied in the same way as described in the TE-A group.
PROCEDURE	Self-etch mode Clearfil Universal Bond Quick (Kuraray, Japan) (SE group)	Universal adhesive system (CBQ) was applied to enamel and dentin surfaces without any previous etching. Then gently air-dried for 5 s without waiting, and light-cured for 10 s.
