BACKGROUND No specific indications about the pre-treatment of indirect composite restorations is provided by the manufacturers of most self-adhesive resin cements. The potential effect of silane treatment to the bond strength of the complete tooth/indirect restoration complex is not available.The aim of this study was to determine the contribution of different surface treatments on microtensile...

Purpose: To evaluate the effect of using separating medium and its type on the microtensile bond strength of indirect resin composite restoration to dentin clinically. Materials and methods: Standard 24 MOD cavities were prepared in the upper first premolars for the selected patients by one operator and restored using indirect resin composite (Grandio So Inlay System, VOCO, Germany). Inlays wer...

In a longitudinal clinical trial the treatment times needed for the fabrication of veneer restorations (VRs) were recorded and analysed. Treatment times were determined for: (1) direct resin composite (DC), (2) indirect resin composite (IC) and (3) porcelain (P) veneer restorations and for two preparation designs, with and without incisal coverage. Significant effects on the treatment times wer...

OBJECTIVE To evaluate the fracture resistance of teeth restored using 2 intracoronal direct and indirect adhesive techniques. METHODS Forty maxillary premolars were divided randomly into 4 groups of 10: group 1, intact teeth; group 2, mesio-occlusodistal (MOD) cavity preparation associated with endodontic therapy (unrestored); group 3, MOD cavity preparation and restoration with direct compos...

background & aim: repair or replacement of restorations is one of the main necessities for health promotion. however, it has its own physical, psychological and economical side effects. the aim of this study was to investigate the prevalence of factors causing restoration replacement or repair. methods & materials: a non probable sampling was used for this cross – sectional observational descri...

this study addresses the question of whether conservative methods of restoration may be applied efficaciously in permanent posterior teeth with proximal lesions and intact occlusal preventive resin restoration (prr). the purpose of the present study was to assess the microleakage at amalgam-composite interface and composite-composite interface in permanent tooth with prr.thirty-five premolar te...

As a result of the increasing needs among public to enhance esthetics, many approaches have been made and results included different as non-metallic tooth-colored restorations, including direct indirect resin composites. In addition, another approach is ceramic onlays or inlays. this study, we aim formulate strong evidence regarding differences between composite clinical outcomes, related effec...

The clinical longevity of tooth-coloured restorations, whether direct or indirect, using composites and ceramics, greatly depends on the quality and stability of their marginal adaptation. In this issue, two interesting studies 7,15 bring this subject and lead us to an exciting discussion. Poor marginal adaptation of direct and indirect restorations exposes the dentin pulp complex to the oral e...

statement of problem: shear bond strength (sbs) of home and office bleached enamel will be compromised by immediate application of composite restoration. antioxidant agent may overcome this problem. objectives: this in vitro study assessed the effect of green tea extract on shear bond strength of resin composite to in-office and home-bleached enamel. materials and methods: in this experimental ...

conclusions estelite sigma quick composite had wear resistance similar to that of nano- and microfilled composites. estelite flowable composites demonstrated similar wear resistance to that of a posterior composite. results the wear amounts of the composites are as follows in order: estelite sigma quick (1886.9 ± 518.5 μm2), estelite flow quick (2708.9 ± 578.1 μm2), estelite high flow (3206 ± 2...
