I've been an Ultradent  customer for almost as long as I've been in business.
Over the last several years, I've also been fortunate enough to lecture for them on a variety of topics.
I'm impressed with the company for a variety of reasons.  It's one of those places that has phenomenal people, outstanding leadership, tremendous ethics, and great products.  It truly is a place where people strive to do the right thing.
I've also had a chance to deal with the folks in their research & development department and I've always been impressed with the quality of their work as well as their dedication to research & their research methods.  To that end, I wasn't' surprised when I received the following announcement from Ultradent and I think you readers should know about it as well.


SOUTH JORDAN, Utah, August 2013 – The International Organization for Standardization (ISO) recently adopted Ultradent Products Inc.’s notched-edge shear bond strength testing method as a new standard. Ultradent created, refined, and has taught the notched-edge testing method over a number of years, resulting in a reproducible technique that many research organizations across the globe use today. After conducting a rigorous study involving over 20 independent organizations, ISO determined the notched-edge method superior to other shear bond strength testing methods previously available. 

ISO Standard 29022 specifies a shear test method used to determine the adhesive bond strength between direct dental restorative materials and tooth structure, such as dentin or enamel. The method is principally intended for adhesives and includes substrate selection, storage and handling of tooth structure, as well as the procedure for testing. A key element within the testing is a notched-edge crosshead used to shear the bonded specimen with an even distribution of force. Testing results are more accurate with a notched contact because they will closely approximate adhesive shear strength, rather than peel strength produced by using a straight contact. 


The ISO develops and publishes international standards to ensure that products and services are safe, high quality, and reliable. ISO protocol is employed by many organizations worldwide such as the Food and Drug Administration (FDA), who often grant approval only to products that pass ISO’s meticulous testing standards.
