background and aims. the condensation silicone impression materials are available, but there is little knowledge of their accuracy after disinfection. the objective of this study was to evaluate the effect of the disinfection by spray atomization on dimensional accuracy of condensation silicone impressions. materials and methods. impressions were made on a stainless steel master model containin...

conclusions within the limitations of this study, disinfectants were able to completely eliminate microorganisms carried by the alginate impressions. however, more efficient disinfection methods are needed to eliminate the risk of cross contamination by condensational silicone impressions. background dental impressions often carry microorganisms that may cause cross-infection from patients to d...

BACKGROUND Dentistry equipment are exposed to different types of pathogenic microorganisms. The aim of this study was to investigate the effect of spraying three different types of disinfectants on condensational silicones after 5 and 10 min. MATERIALS AND METHODS Totally, 66 circular samples of condensational silicone impression materials of 1 cm diameter and 2 mm thickness were contaminated...

BACKGROUND Marginal adaptation is very important in cast restorations. Maladaptation leads to plaque retention, reduction of mechanical and esthetic properties. The aim of this study was to evaluate the precision of three different impression materials (including: Additional silicone [AS] and condensational silicone [CS] and polyether [PE]) for duplicating master dies. MATERIALS AND METHODS T...

background to prevent diseases transmission, infection control in dental offices without reducing the accuracy and dimensional stability of impression materials is very important. objectives the aim of this study was to evaluate the effects of sanosil disinfectants on the dimensional stability of some usual impression materials. materials and methods three types of impression material, namely, ...

INTRODUCTION Use of submicrometer particles combined with condensational growth techniques has been proposed to reduce drug losses within components of high-flow nasal cannula therapy systems and to enhance the dose reaching the lower respiratory tract. These methods have been evaluated using continuous inhalation flow rather than realistic inhalation/exhalation breathing cycles. The goal of th...
