microleakage is a main cause of restorative treatment failure. in this study, we compared occlusal and cervical microleakage of two self-adhesive cements after 24 hours and two months.in this in-vitro experimental study, class ii inlay cavities were prepared on 60 sound human third molars. composite inlays were fabricated with z100 composite resin. the teeth were randomly assigned to six groups...

OBJECTIVES Extensively destroyed teeth are commonly restored with composite resin before cavity preparation for indirect restorations. The longevity of the restoration can be related to the proper bonding of the resin cement to the composite. This study aimed to evaluate the microshear bond strength of two self-adhesive resin cements to composite resin. MATERIALS AND METHODS COMPOSITE DISCS W...

Resin cement diffusion into dentin may differ as a function of the pre-treatment regimen. Since self-adhesive cements do not require substrate pre-treatment for luting, penetration of and interaction with the underlying dentin are questioned. We hypothesized that differences in the resin cement diffusion into dentin may exist among current commercial adhesive cements. Composite cylinders were l...

This in vitro study evaluated the adhesive interface of intraradicular fiber glass posts and root dentin using scanning electron microscopy (SEM). Forty-eight single-rooted premolars were randomly divided into 6 groups consisting of chemical, dual, or light cured adhesive systems combined with either chemical or dual cure resin cements. Scanning electron microscopic analysis showed the best res...

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...

Aim: Mechanical characteristics of tooth preparation along with luting agents are significant entities on the maintenance of fixed dental prostheses. This study aimed at assessing the retention of complete metal crowns luted with two different luting agents using two different preparation height. Methods: Forty human maxillary premolars were selected and prepared to receive complete metal crown...

RelyX Unicem cement is a dual-curing, self-adhesive universal resin luting cement for adhesive cementation of indirect ceramic, composite or metal restorations. When using RelyX Unicem cement, bonding and conditioning of the tooth are no longer necessary. The cement is characterized by a higher moisture tolerance, as compared to multi-step composite cements. RelyX Unicem cement releases fluorid...

Introduction. Vertical root fracture (VRF) is one of the most frustrating complications of root canal treatment. The prognosis of the root with VRF is poor therefore tooth extraction and root amputation are usually the only treatment options. However, bonding of the fracture line with adhesive resin cement during the intentional replantation procedure was recently suggested as an alternative to...

Since luting cement is used for fixing cast restorations to their abutments, the cement surface at the junction between cast and tooth is exposed to oral environment. The conventional cement so far used does not adhere to the tooth and is slightly soluble into saliva and gingival fluid1,2). Consequently, the microleakage and subsequent recurrent caries seem to develop at this junction. Recently...

The purpose of this paper was to compare the bond strengths of the self-adhesive luting cements between ceramics and resin cores and examine their relation to the cement thickness. Three self-adhesive luting cements (Smartcem, Maxcem, and G-CEM) and a resin cement (Panavia F 2.0) for control were used in the paper. The thickness of the cements was controlled in approximately 25, 50, 100, or 200...
