The Ultralime is a new polymerization light from Citrus Products. It has a light shift toward the green spectrum so that it will cure those products rarely is not ever used in dentistry.

Pay back for your typos is really going to be fun!

I just got a ultralume 5, I do not have a light meter handy as my old Bisco VIP light had one built in. It does not seem that bright.

I understand that it only generates light wavelengths that are needed to cure dental materials, does that mean If it generates lets say 400mw/cm2 it would be as good as a halo light generating 600?

does the same light strength come out of those small accessory tips?
if not do you increase your cure time or is 30 sec enough

do you use those tips much?


John, you mentioned in this thread your recommended time for curing. Is that with this light? sim 10s/flow20-40s/interlayer10s/top 20s (I assume pulsing)

When you are using the triodent rings and bands, it forces you to cure a good distance away from the surface, than you would without the rings. When curing that flowable layer. I upped my curing time to 30 sec for that layer..am I good with this?

Hope these are not too many questions. I did try bulit in light gauge on a demetron light, but I only got about 450mw. I hope this is wrong because I have been using 600mw with my old Bisco VIP and I have had no trouble.

The Ultralumes I've tested, using independently manufactured radiometers, all show about 1000mW/cm2. I would guess the meter you tried is off. Not the Ultralume.

I hope you are right, I will try and get a new one and check it.

I have a neat digital radiometer at the office along with a couple of analogs. The digital also has a heat read out. I'll post the name and mfg. of the device tomorrow when I gat back in.

You'll love the UL5.

the tips I got were

a white proxicure to use in class 2 box and a point cure with a 2.5 mm aperture, (It is suggested to spot cure veneers)
plus 2 Translume lenses, one green and one orange..

didn't you invent some kind of special lens for increasing contacts? I did not get that one

It also said that the LED light do not cure through porcelain as well as the halogen light...do you still recommend the 10 sec cure with a minute in between for veneers for a total of 60 sec? with this light?

They are sold separately.

I don't know why that would be true. So the answer is yes.

Radiometers

Digital = HILUX First Medica (Has infrared and blue light sensors)

Analog = OPTILUX Kerr

I have another but its not my favorite. THe HILUX is!

Nasser Barghi, Elizabeth H. McAlister

LED and Halogen Lights, effect of ceramic thickness and shade on curing uting resin Compendium Volume 24 No 7 July 2003

This was the article quoted in the Ultra-Lume Manual.

Interesting! Thickness and shade I can understand but source (LED v Halogen) is a puzzle.

I'll check the article.

Thanks!

JPOS 10/12 2004 QTH v LED through ceramic

The halogen and LED light intensities were 760mW/cm2 and 130mW/cm2, 80 seconds were required for the LED whereas 60 seconds were required for the QTH.

Not surprising considering the power density difference! Still the authors feel that LED or QTH is fine but 120 seconds is the recommended curing time.

Still new with the surpass...Is it OK to really thin out the sur 3, when sealing after crown preps, or before cementation of crowns? because it seems a little thick. and if the answer is yes, does that affect the bond strength.

can you do that as well with direct restorations or is it better to leave a little thickness (of course with no pooling)

I recall years ago it was suggested to keep a thicker layer of adhesive on class V's to allow for a little more flexure to the restoration and avoiding "pop offs" Is that same theory valid now, again I am going back to the thickness of the sur 3...do we leave it thick or really thin it out?
