A randomized five-year clinical study of a two-step self-etch adhesive with or without selective enamel etching.

The purpose of this study was to evaluate the five-year clinical performance of a two-step self-etch adhesive in non-carious cervical sclerotic lesions with or without selective acid-etching of enamel margins. A total of 104 cervical restorations in 22 patients (46-64 years) were bonded following either self-etch approach (AdheSE non-etch) or a similar application, including selective acid-etching of enamel margins (AdheSE etch), and were restored with resin composite. The restorations were evaluated at baseline and after one, two, three and five-years (84 restorations in 19 patients) according to the USPHS criteria.

The effect of prophylactic polishing pastes on surface roughness of indirect restorative materials.

The purpose of this study was to evaluate the influence of prophylactic polishing pastes (PPP; Detartrine (DT), Topex (TP)) on surface roughness (R(a)) of indirect composites (IRC; Tescera (TES), Gradia (GRD), and Estenia C&B (EST)), a glass ceramic (Empress 2 layering (E2)), and a leucite reinforced glass ceramic (Empress Esthetic (EE)) with two different (glazed (G); polished (P)) surface preparations. A total of 90 IRC and 120 ceramic discs, 8 mm in diameter and 2 mm thick, were prepared. E2 and EE specimens were randomly divided into two groups (n = 30).

Surface roughness and morphology of resin composites polished with two-step polishing systems.

The purpose of this study was to investigate surface roughness (Ra) and morphology of supra-nanofilled [Estelite Omega (EO), Estelite ∑ Quick (EQ)], micro-hybrid [Esthet.X HD (EHD), G-aenial (GAE)] and nano-hybrid [Clearfil Majesty Posterior (CMP), Charisma Diamond (CD), Beautifil II (BII)] composites polished with two-step polishing systems [Enhance/PoGo (EP); Venus Supra (VS)]. Composite discs, 30 of each type, were prepared.

Three-year clinical evaluation of a two-step self-etch adhesive with or without selective enamel etching in non-carious cervical sclerotic lesions.

Objective: The purpose of this prospective, controlled, randomized study was to evaluate the 3-year clinical performance of a two-step self-etch adhesive (AdheSE, Ivoclar Vivadent; Schaan, Liechtenstein) in non-carious cervical sclerotic lesions with or without selective acid-etching of the enamel margins.

Material And Methods: Twenty-two patients (mean age 51.5) having at least two pairs of non-carious cervical sclerotic erosion⁄attrition⁄abfraction lesions with incisal or occlusal margins in the enamel and gingival margins in the dentin were included in the study.

Shear bond strength of resin cement to an acid etched and a laser irradiated ceramic surface.

Purpose: To evaluate the effects of hydrofluoric acid etching and Er,Cr:YSGG laser irradiation on the shear bond strength of resin cement to lithium disilicate ceramic.

Materials And Methods: Fifty-five ceramic blocks (5 mm × 5 mm × 2 mm) were fabricated and embedded in acrylic resin. Their surfaces were finished with 1000-grit silicon carbide paper.
