INTRODUCTION For the construction of any dental prosthesis, accurate impressions are necessary. Hence, we undertook the present study to evaluate and compare the surface hardness of gypsum casts poured from impressions made using conventional alginate and self-disinfecting alginate. MATERIALS AND METHODS A total of 30 impressions of stainless steel die were made, out of which 15 impressions w...

The present study investigated the effect on the surface quality of resultant stone models of rinsing hydrocolloid impressions using acidic electrolyzed water. Two brands of alginate impression materials (Aroma Fine DFIII, Jeltrate Plus), an agar impression material (Ajisai) designed for agar/alginate combined impression, and dental stone (New Plastone) were used to make the test specimens. For...

This work addresses the problems of automated response systems in Wireless Mobile Ad Hoc Networks (MANETs), which is challenging because the topology of these networks are dynamic and the fully distributed cooperation among nodes makes not only the false positives of intrusion alarms high but also complicates the response analysis. We present a cooperative, distributed and automated response mo...

Previous research has demonstrated that older adults have difficulty retrieving contextual material over items alone. Recent research suggests this deficit can be reduced by adding emotional context, allowing for the possibility that memory for social impressions may show less age-related decline than memory for other types of contextual information. Two studies investigated how orienting to so...

OBJECTIVES Similarity to the self has been shown to affect memory for impressions in younger adults, suggesting a self-reference effect in person memory. Because older adults show comparable self-reference effects, but prioritize memory for positive over negative information relative to young adults, we examined age differences in self-similarity effects on memory for positive and negative impr...

PURPOSE The aim of this in vitro study was to compare the accuracy of two different impression techniques for the All-on-Four implant therapy protocol. MATERIALS AND METHODS An acrylic resin analog for an edentulous maxilla with four internal connection implants (Replace Select, Nobel Biocare) was fabricated according to the All-on-Four protocol. A total of 40 impressions were made with diffe...

Not all Wrst impressions have equal longevity. Which kinds of impression have the greatest mobility—downward and upward—over the course of acquaintanceships? In this article, we propose an inferential account of impression maintenance across Big Five trait domains. With data from Weld and laboratory studies, we provide evidence that positive impressions of agreeableness (A), conscientiousness (...

Abstract: A novel dust free alginate impression material was formulated and prepared, comprising an alginate polyvinylpyrrolidone and tetraflouroethylene resins, a mixture of liquid paraffin and dimethylpolysiloxane oil as the dust generation controlling agents and processed diatomaceous earth filler which was obtained from Iranian ore. No dusting was detected during the mixing of the powde...
