Purpose. To investigate the cavity adaptation of mineral trioxide (ProRoot MTA/MT), tricalcium silicate (Biodentine/BD), and glass ionomer (Equia Fil/EF) cements used as liners and the interfacial integrity between those liners and a composite resin placed as the main restorative material. Materials and Methods. Standardized class I cavities (n: 8 per group) were prepared in upper premolars. Ca...

OBJECTIVE The aim of this study was to evaluate the marginal adaptation of Biodentine in comparison with Mineral Trioxide Aggregate (MTA) and Intermediate Restorative Material (IRM), as a root end filling material, using Scanning Electron Microscopy (SEM). MATERIALS AND METHODS Thirty permanent maxillary central incisors were chemo-mechanically prepared and obturated. Three millimetres of the...

the aim of this study was to introduce modified continuous wave compaction (mcwc) technique and compare its obturation quality with that of lateral compaction (lc), warm vertical compaction (wvc) and continuous wave compaction techniques (cwc). the obturation time was also compared among the four techniques.sixty-four single-rooted teeth with 0-5° root canal curve and 64 artificially created ro...

the present study is an attempt to analyze the characters in the novel blindness and its cinematic adapta- tion from intersemiotic viewpoint. to this end, the researchers provided a synthesized model, which is a combination of bernando (2012) and forster's (1927) classification of characters in order to analyze the two main characters from intersemiotic viewpoint. considering the differenc...

Introduction – Shrinkage during polymerization of resin-based composite materials may lead to gap formation and hamper the marginal adaptation of the restorations. To reduce the problem of polymerization shrinkage, a new composite material (FiltekTM Silorane, 3M-ESPE, Germany), with a reduced shrinkage, has been marketed. Objective – To investigate whether reduced polymerization shrinkage impro...

Local adaptation is used as a criterion to select plant materials that will display high fitness in new environments. A large body of research has explored local adaptation in plants, however, to what extent findings can inform management decisions has not been formally evaluated. We assessed local adaptation literature for six key experimental methodologies that have the greatest effect on the...

conclusions although the cmr was originally designed for use in tc treatment, this study suggests that it is also applicable, with some modifications, in short-term residential camps. also, it is concluded that the persian translation of the cmr can be applied for studies among persian addicts. background treatment motivation has always been an important issue in substance abuse treatment. in r...

We present a simple and practical method for rendering leaves and other translucent parts of plants. In contrast to other translucent materials, plant leaves usually are thin, though highly textured. An adaptation of rendering methods for translucent materials in combination with a set of predefined textures allows us to represent plants realistically. A hardware-based approximation of the shad...

As part of an overall effort to address obesity among elementary schoolaged children, the US Department of Agriculture (USDA) developed MyPyramid for Kids (Figure 1), a childfriendly adaptation of the MyPyramid Food Guidance System. MyPyramid for Kids is designed to help children 6-11 years old understand and follow the dietary guidance of the MyPyramid Food Guidance System. Materials developed...
