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, ...
objective: among the various impression materials, for alginate tear strength is probably more important than the compressive strength. the tear strength is important when an impression involves a mechanical undercut and/or lacks bulk strength to resist tearing. this study evaluated tear strength of iralgin and compared it with tear strength of alginoplast. methods: in this invitro experimental...
introduction: complete adhesion of the impression materials to trays is important to prevent impression materials from being pulled away from trays during removed from the mouth and to ensure that the direction of polymerization shrinkage will be towards the tray. the aim of this study was to evaluate the effects of two retention features of custom trays (adhesive vs holes) on the dimensional a...
BACKGROUND Dental stem cells in combination with implant materials may become an alternative to autologous bone transplants. For tissue engineering different types of soft and rigid implant materials are available, but little is known about the viability and the osteogenic differentiation of dental stem cells on these different types of materials. According to previous studies we proposed that ...
objectives: this study aimed to assess the effect of storage time and temperature on dimensional stability of impressions made with cavex outline zinc oxide impression paste. materials and methods: a round stainless steel mold with five grooves (three horizontal and two vertical) was used in this in-vitro experimental study. cavex outline impression paste was prepared according to the manufactu...
context this study aimed to provide an overview of the literature on the radiopacity of dental materials in order to emphasize its importance. evidence acquisition english-language literature was investigated using manual and electronic searches for the terms “radiopacity,” “dental material,” “cement,” “composite,” “ceramic,” “endodontic root canal sealer,” “bone graft,” and “acrylic resin” in ...

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...
