The speed of light

 If you've been in dentistry for a few years you can attest to how curing lights have gotten quicker.

First we had 30-second cure times. Then 20-seconds, then 10-seconds, then 5-seconds. Now we have reached an even higher level of efficiency with 3-second curing lights.The light in question is the Flash Max P3, distributed in Australia by Amalgadent.If you do any form of composite dentistry and you are interested in becoming more efficient then you need to buy this light.
