Using a Thermal Camera to Record the Temperature Rise as a Composite is Light Cured in a Tooth
Irradiance vs.Power from the Curing Light
Просмотров 62Месяц назад
This video compares the irradiance measured from a curing light with the measured power. It can be seen that a curing light that is measured to have a high irradiance value does not always have a high power output. This is because the irradiance is calculated from the power/the tip area, and determining the active tip area is not always easy.

Nesse vídeo comparamos a potência de um fotopolimerizador com a irradiância. Pode-se observar que nem sempre um fotopolimerizador que possui uma alta irradiância possui uma alta potência.
Diferenças entre diversos Radiômetros

Differences between the outputs from several radiometers

This video uses several radiometers from different brands to measure two curing lights. You can see that the Blurphase Meter II can report the power of the curing lights and the other two radiometers showed rather different values. Which one tells you how powerful the lights are?
Is Bluephase accurate? Bluephase Meter II Compared to the MiniGig
Просмотров 45Месяц назад
This video uses two lights to compare Ivoclar's Bluephase Meter II with Ultradent's MiniGig. As you can see, the Bluephase Meter II is an accurate power meter. Note that measuring the radiant power from the curing light is a much better way than reporting the irradiance due to the vagaries of determining the active light tip area (irradiance= power/area)

Fotopolimerizando uma resina composta com fotopolimerizadores com pontas de tamanhos diferentes
Просмотров 102Месяц назад
Este vídeo demonstra o efeito da fotopolimerização de um disco composto do mesmo tamanho que a dimensão mésio-distal de um molar inferior por 10 s com uma luz fotopolimerizadora de ponta pequena e grande. Observe que a pequena ponta de luz não cobre totalmente o compósito. Após a imersão em acetona, a pequena ponta de luz não cura muito bem o compósito além da ponta de luz. Isso acontece tanto ...

Effect of light-curing a composite with small and large tip curing lights
Просмотров 842 месяца назад
This video demonstrates the effect of light-curing a composite disc that is the same size as the mesio-distal dimension of a mandibular molar for 10 s with a small and a large tip curing light. Note that the small light tip does not fully cover the composite. After immersion in acetone, the small light tip does not cure the composite very well beyond the light tip. This happens both at the top ...

    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 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%

    • @CuringLights
      @CuringLights 8 месяцев назад

      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.
