Kanna Member Since: 08/01/13 Post: 1 of 43 My curing method from dental school: Cure in 10-second increments, last increments for 20 seconds instead of 10 seconds. How is pulse-curing different in terms of both method and result? ■ SEPT 17 2015 Flyfishindoc Member Since: 04/06/04 Post: 2 of 43 Related Message Boards Tell Me Everything I Need to Know About Pulse Curing Everything Pulse Pulse Curing Changed My Life! Pulse Curing Ok, here is the 101 on pulse-curing. It seems that curing lights are always advertised as the fastest cure. That is not what you want. The faster the cure, the more (and faster) the polymerization shrinkage. This leads to composite pulling away from the tooth. This results in temperature sensitivity and biting sensitivity. The idea behind pulse-curing is to slow the process and reduce polymerization shrinkage. I use a Valo light (Ultradent). I use the normal cure setting at five seconds for the first intervals. Then the last layer is only cured for one second. Then, after polishing, it is cured again for 10-20 seconds. The only change to this protocol is for Class V restorations, where every layer is one second. Don't worry about incomplete curing. Composite is not so much light-cured as light-initiated. So the polymerization will continue (slowly) after the light is off the tooth. Try an experiment. Take a blob of composite (pea size). Hit it with the curing light for one second or less. Check if it's hard everywhere. It won't be. Check it in five minutes. It will be more cured at that point. The main idea behind pulse-curing is to cure slowly, so it shrinks slowly, and you maintain a strong bond over the entire tooth/composite interface. When you achieve this, post-op temperature and biting sensitivity will disappear from your practice. ■ SEPT 17 2015 almunk Member Since: 12/17/05 Post: 3 of 43 Or you can do it another way: Cure for two seconds, move light away for two seconds, repeat. This supposedly relieves some of the shrinkage stress on the tooth. ■ SEPT 17 2015 JimmyJames Member Since: 04/10/12 Post: 4 of 43 I wait until all finishing and polishing is completed until doing the final cure. This is a few minutes after the last "pulse" cure. I'm probably putting incorrect words in John's mouth, but I thought he said you wanted those few minutes in between. ■ SEPT 17 2015 Flyfishindoc Yes. That is correct. That is why I finish, adjust occlusion, and then polish before the final cure. ■ Member Since: 04/06/04 Post: 5 of 43 DentistPk Member Since: 05/07/15 Post: 6 of 43 SEPT 17 2015 Sorry, but this really confuses me a lot. Can you please tell me how to pulse-cure in a Class II cavity? Here, I will make this easier for you to reply with. The question mark refers to pulse-curing time (normal/pulse mode?)
