    Is there any block out needed around gingival margins? So not to iritare gumline of patient? Or is that a simple chair side adjustment? Thank you fornthe great video!

    In cases of severe undercuts, maybe. It is a case-by-case situation. No blockout is required usually.

    Caleb: Good point, but many amalgam users think you can pack a composite ike an amalgam. You cannot. This is why I like to use heated compules of composite, incrementally placed and adapted, but then bulk cured.

    This is an interesting video, but I'd like to see the demonstration redone with less initial composite and a more appropriately sized condenser. I feel like most people would take a smaller first increment and really focus not so much on compacting the composite but pushing it down into all the preps line angles

    Hello, thank you for putting out these videos. I just finished my PhD and was pleased to reference you a number of times. I have a question though. I used the Bluephase to measure the output of my LCU, which was a BASE290 from BA International. It's dual peak. I was getting different readings for every subsequent push of the button. Do you know why that might have happened?

  • @CuringLights
    @CuringLightsАй бұрын

    No idea, was it in ramp mode, were you measuring power or irradiance?

  • @herrzyklon
    @herrzyklonАй бұрын

    @@CuringLights hello, thanks so much for replying. It wasn't in ramp mode, it was in full power mode (3000 mW/cm^2 peak), and I was primarily measuring irradiance. I measured over 200 consecutive 5 second cycles, each at full power, with a pre-set (by the LCU) rest between cycles of 5 seconds. Irradiance dropped off sharply for the first dozen cycles (from memory) before the drop was a few tens of mW/cm^2. The battery only lasted long enough to measure 200 cures. Total drop was about 10%

    Hello, I recently had the opportunity to explore your KZread channel. I must say that I am impressed with the quality of content you are creating. Your video doesn't have a good Thumbnail. it has come to my attention that the title description, video tag, video SEO and high-volume keywords are not included ―This is why you don't get much more views from your content . I also saw in your videos that your videos are not S.E.O friendly (Search Engine Optimization) while you upload video. If you want I can send you a audit file of your channel issues.

    Hm.....what if you use 1 second light for 3/ 5 times.....allso, from diferent angels. Sure, with few seconds of pause...cos, we do not wish to burn the nerv?!? Is it still so bad...ore become a winer? Allso, G4 have to small aperture/ 8mm....and can not cower biger area,which will cose a problems with ununique polimerisatione.

  • @CuringLights
    @CuringLights8 ай бұрын

    Well, it all depends on the light output. Let's say you use a light that delivers 1,500 mW/cm2 for 10s. Then you will deliver 15 J/cm2 of energy. If your light delivers 3,000 mW/cm2 then you would have to use it for at least 5 s to deliver the same amount of energy. Unfortunately, dental composites do not obey exposure reciprocity, so you actually have to deliver more energy as the irradiance goes up. Start curing from angles, even less energy is delivered. Simple physics and simple chemistry. Sorry to burst the bubble on fast curing.

    It would seem that using flowable in the bottom of the box would address the flow and void issues, like in a PVS imression. Also using a big increament in the initial example and then using the unidose tip in the warmed example is not exactly apples to apples.
