The aim of this study was to evaluate the influence of accelerated aging (AAA) on the color stability of resin cements for bonding ceramic laminate veneers of different thicknesses. The occlusal surfaces of 80 healthy human molars were flattened. Ceramic laminate veneers (IPS e-max Ceram) of two thicknesses (0.5 and 1.0 mm) were bonded with three types of luting agents: light-cured, conventiona...

General structure and properties Glass-ionomer cements were developed by Wilson and McLean at the Laboratory of the Government Chemist in England in 196527. They were a logical addition to the family of water-based dental cements, comprising silicate cement, zinc phosphate cement and zinc polycarboxylate cement. Since their commercial introduction, they are now available in essentially two type...

The aim of this study was to evaluate the diametral tensile strength (DTS) of composite resins submitted to different curing techniques. Four composite resins were tested in this study: Targis (Ivoclar), Solidex (Shofu), Charisma (Heraeus-Kulzer) and Filtek Z250 (3M Espe). Sixty-four cylindrical specimens were prepared and divided into eight groups according to each polymerization technique (n ...

OBJECTIVE The aim of this study was to evaluate the pulp response following cementation of inlays using two different resin cements. METHODS Deep Class V cavities were prepared on the buccal surface of 34 sound human premolars. Impressions were taken and inlays were prepared which were cemented with the following luting materials-Group 1: Rely X Unicem (3M ESPE); Group 2: Variolink II (Ivocla...

Due to the availability of a large number of luting agents (dental cements) proper selection can be a daunting task and is usually based on a practitioner's reliance on experience and preference and less on in depth knowledge of materials that are used for the restoration and luting agent properties. This review aims at presenting an overview of current cements and discusses physical properties...

PURPOSE To review the performance of self-adhesive luting agents to determine their clinical evidence. MATERIALS AND METHODS In March 2013, we conducted a literature search by means of PubMed and manually searched German and English medical journals using general search terms (e.g., "self-adhesive resin cements"), detailed search terms (e.g., clinical study "self-adhesive resin cement"), and ...

Case Presentation. Implant prostheses are a successful treatment for replacing missing teeth. However, this treatment modality can have biological and mechanical complications causing serious problems for the dentist, as demonstrated in this clinical case. The patient presented with a fractured screw and a severely damaged implant hex connection that corresponded to the second premolar, upper l...

The search for an all-purpose luting system for final cementation that fulfills the properties necessary for definitive placement of cast metal, porcelain-metal, resin, and all-ceramic fullcoverage restorations has been limited by the physical properties of the cements that have been available. Currently the clinician has many choices for cementation. Despite the challenges of the current resto...

PURPOSE To assess the sealing properties of four luting materials used for cementation of full cast crowns. METHODS 40 human premolars were prepared with a chamfer finish line. Stone dies were fabricated and copings were waxed, invested and cast in gold. Ten samples (n = 10) were randomly assigned to four groups. In two groups, resin modified glass-ionomer cements were used, ACTIVA BioACTIVE-...

A modified direct contact test was used to evaluate the antibacterial properties of four commercially available dental luting agents (RelyX Unicem, Ketac Cem, Ceramir Crown & Bridge and Harvard Cement) and two reference materials (glass-ionomer cement and calcium aluminate cement) compared to a negative-control material (PMMA). Streptococcus mutans bacteria were placed in direct contact with sp...
