The purpose of this study was to assess the color of layered resin overlays and to test the early microhardness of dual cure resin cement (DCRC) light cured through the layered resin overlays. Resin overlays of 1.5 mm thickness were fabricated with the A3 shade of Z350 (Group 1L), the A3B and A3E shades of Supreme XT (Group 2L), and the A3, E3, and T1 shades of Sinfony (Group 3L) using one, two...

PURPOSE To investigate different techniques used by dentists when luting an implant-supported crown and to evaluate the application of cement quantitatively and qualitatively. MATERIALS AND METHODS Participants were given a bag containing cement sachet, mixing pad, spatula, a variety of application instruments, and a polycarbonate crown form. The participants were instructed with a standardiz...

AIM This study evaluated the effects of ceramic veneer thicknesses on the polymerization of two different resin cements. MATERIALS AND METHODS A total of 80 ceramic veneer disks were fabricated by using a pressable ceramic material (e.max Press; Ivoclar Vivadent) from a Low Translucency (LT) ingot (A1 shade). These disks were divided into light-cured (LC; NX3 Nexus LC; Kerr) and dual-cured (D...

diabetes mellitus is a chronic disease which affects the healing ability of the pulp and periodontium. the aim of the present study was to assess the histopathologic response of dental pulp to pulp capping using mta or cem cement in diabetic rats. thirty two wistar male rats aged between 8 and 10 weeks (weight: 200-250g) were divided into two groups of diabetic (n=16) and healthy (n=16) animals...

AIMS The aim of this experimental study is to assess the bone healing phenomenon produced in the presence of several dental materials: a polycarboxylate cement, a glass-ionomer cement, a composite resin and MTA (mineral trioxide aggregate) based cement. METHODS The biocompatibility of four root-end fillings materials, used in periapical surgery was investigated after intra-osseous implantatio...

It has been the purpose of this article to provide a rationale for the restoration of endodontically treated teeth. Treatment recommendations have been made in the areas of post design, placement technique, cements, core materials, and definitive restorations, based on a review of the clinical and laboratory data.

The aim of this study was to assess the effect of some foods consumed previous to an erosive beverage on dental enamel and cement. The study was performed on 40 human teeth unaffected, extracted for orthodontic braces. The teeth were cut to obtain 80 cervical slices including enamel and dentine/cement areas. The slices were randomly divided in four groups. The 20 samples of control group (group...

As implant dentistry has grown in popularity, many clinicians have attempted to simplify their protocols to more closely resemble conventional crown and bridge procedures. However, a thorough understanding of the biologic differences between natural teeth and dental implants, as well as the types of cements employed, is essential to achieving both short- and long-term success, as these biologic...

BACKGROUND The cementation of crowns to dental implant abutments is an accepted form of crown retention that requires consideration of the properties of available cements within the applied clinical context. Dental luting agents are exposed to a number of stressors that may reduce crown retention in vivo, not the least of which is occlusal loading. This study investigated the influence of compr...

Introduction: Total joint replacement has long been the most effective treatment for severe arthritis in the hip. The most common clinical problem associated with the surgery is long-term aseptic loosening of the implant. The limited durability of the artificial joint, and the difficulty of revision surgery, have limited the potential applications of this treatment, particularly in younger and ...
