Dr. Michael DiTolla
Demi LED Light Curing System from Kerr Demetron.. I must tell you upfront that this light is a favorite of mine because I feel that I have had a hand in bringing it to market. Two years ago at the Kerr Roundtable, we (Key Opinion Leaders - KOL) had a chance to tell the Kerr Demetron people what we would like to see in a curing light. Last year, we were shown a mock up of a new light and again given the chance to comment on what we liked and did not like. Last week (middle of August) I saw the finished product and it is everything we asked for and more. It is compact in size and light weight and easy to hold. The LED unit is cordless and offers multiple ways to hold it which makes the light more ergonomic. You will immediately notice less stress on your hands and wrists. Demi has a super quiet built in fan that keeps the unit cool. Superior battery technology gives longer working time and it can last 3 to 4 days when fully charged. Demi features the Periodic Level Shifting technology which simply means the light gets more intense part of each second. You can do a true five second cure! No need to buy a bunch of new light tips, it accommodates all Demetron light guides. The 5-, 10- and 20-second preset timer settings reflect todays shorter curing times and the timer mode will automatically recall the last curing time selected. If you are in the market for a new LED light that is well planned with features to make dentistry faster, better and easier, this is it!
