Many of my children have made careers here at Ultradent. I'm proud of the family culture we have here—a culture that spans our global campus with our global family. Our large and global Ultradent family recently gathered for our annual State of the Company address. We highlighted achievements, showcased future plans, and celebrated our people. I was overjoyed to see our core values exemplified in our work. We've had a remarkable year at Ultradent. We've introduced new products, aided inspiring humanitarian efforts, and furthered our vision of improving oral health globally.

This month we’re launching our My Smile is Powerful Opalescence® Whitening Systems campaign. What does the phrase, “my smile is powerful” mean to you? We firmly believe that all smiles are powerful. The phrase “my smile is powerful” relates back to the things I’ve been saying in my lectures for years. The smile—the lips and the teeth—are the number one body language communicator. In fact, statistics show that when people first meet, 50% of people look at the other person’s eyes first, and the other 50% notice the smile and teeth first. A thousand words can be communicated in an instant with a smile. It’s a fabulous communicator! It radiates the inner feeling and soul of the other person, and it enables them to communicate beyond words, or it accentuates words in an instant. It is so powerful.

Having grown up in, and then subsequently leaving the FLDS society–which was very oppressive and ultra-conservative, freedom is a big deal to me. The more in balance freedom and responsibility are, the more they work together towards good.

Irradiance vs power, beam size, even the tools used to measure light outputs all play major roles in how a curing light will function. To find true quality and efficiency in a light, a user must be able to wade through the waves of false and misleading claims often made in the world of dental curing light advertising—Ultradent’s Sr. VP of Research & Development, Neil Jessop, delves into these topics and more in this edition of Dentistry Decoded: Insights from R&D.

While there is no doubt irradiance adds value, it does not tell the full story of how well a light will cure various materials. Irradiance tests typically only show the irradiance of a very small portion of the light. Measuring the power distributed over the entire beam tells a more comprehensive story of its curing capabilities.
