Patient discussion about material

Q. What is the ingredient in perfume or Cologne that will trigger an asthma attack? There is something in cologne/perfume that's not in body spray that triggers my asthma. I went out with a friend and he had on cologne and my asthma starting bothering me. Before going out my asthma hadn't bothered me in months because I stay away from things that may trigger an attack. This often happens with other things like bleach, ajax or any bad odor

A. Anything that irritates the nose and bronchi can cause an attack. No one really knows why...but it does. Cigarettes and pollution are common cause also.

In this study highest percentage of faults were presence of air bubbles while using the alginate impression materials by both groups of students and least error this was separation of material from impression tray.

The purpose of this study was to compare and evaluate the internal adaptation of framework fabrication using two impression techniques, and it was hypothesized that there would be no difference in the clinical internal fit of framework when either an intraoral scanner or a vinyl siloxane ether impression material has been utilized to develop an impression technique.
Two tissue stops, each at the canine region and exposed hard palate, help in proper vertical seating of the tray and control the thickness of impression material [15] (Figure 10).
A single component impression material with higher tear strength could cause severe trauma to the tissues during retrieval of the set impression.
Polyvinyl siloxanes are frequently reported to be the most ideally elastic impression materials because they exhibit better elastic recovery and less permanent deformation than the other elastomers.
Dimensional changes in impression materials may arise from many possible causes, such as contraction due to syneresis, imbibition when exposed to water or a high-humidity environment, or incomplete recovery from deformation due to viscoelastic behavior.

Impression is basically an interaction between tissues and impression material. The variety of impression materials and the range of working characteristics of these materials, make possible the development of impression procedures best suited for specific conditions.
