Dentists test LEDs
LED instruments make it possible to work in daylight quality light. The quality of the lighting facilitates precise diagnosis and makes it possible to achieve optimum results. LEDs give dentists a pure, white and neutral light in the treatment area.

Power and ergonomics
I have worked with “light multiplier” contra-angle handpieces for more than 15 years. I bought the Synea TA-98 C LED turbines a year ago. My assessment is extremely positive because this type of turbine combines power, ergonomics and light. This light is exceptionally bright (at least three times as bright as the old lighting), it is white, athermal and enables considerably better contrast. In our job, it is important to be able to see things close-up and clearly. It’s alright to dream – so why not imagine that one day, there will be an LED camera on the end of our rotation instruments and an optical waveguide fine enough to enable us to investigate all of the root canals?

A significantly longer lifespan
The LED light channel at the end of my turbine enables me to see my working area much more clearly. That is an extremely positive innovation when compared to halogen tubes and optical waveguides. It gives the impression that you have far more space to work in. My eyes now get a lot less tired.
Another advantage of LEDs is that the light emitted is cold, which means that the LEDs have a far longer lifespan. It also feels like the instrument head has a new design, as it is much finer and more ergonomic. Despite the projections on the instrument head, there was no loss of power during the working sequences, which regrettably was the case with optical waveguides. I would welcome the introduction of this type of lighting in the whole product range of rotation instruments, particularly in the contra-angle handpieces used in implantology.

A real advantage in endodontics
I purchased a Synea LED turbine on the recommendation of a colleague, who was already using them. The light emitted is perfect; the intensity of the light beam and the area illuminated represent real progress, and the positioning at an angle of 45° instead of 90° is ideal.
You get the same level of comfort as when working with a microscope, especially in the lingual and palatinal regions. In endodontics, this is a real advantage. Sometimes I work without operating lighting and I don’t miss it at all. One thing I would like would be an even wider beam of light, in order to illuminate the entire mouth.

Very efficient for osteotomies
After using LED contra-angle handpieces in surgery for a year, I am extremely satisfied with the results and I really admire the technicians who developed this type of whiter light. It is certainly a big step forward although, to make full use of the development, my working space would need to be even larger.
In surgery, the instrument head often becomes soiled; here, however, we do not have to worry about cleaning and there is also no loss of power despite the many sterilization procedures. I am really looking forward to being able to use the LED handpiece, which I am sure will be extremely helpful in many osteotomies, where the illumination of the operating area really has been inadequate until now.

Pay attention to the pressure in the unit’s hoses!
Since I have been using the new LED turbines with microheads and standard heads, I don’t use the old ones any more, as the visibility with the new turbines is in a different league: clearer, better focusing on the working area, diffuse white light that isn’t blinding and it adapts well to all the optical aids of the operating unit. Despite the sterilization procedures, I have not yet experienced any deterioration, as was the case with the old optical waveguides.
I would like, however, to point out the following: close attention must be paid to the pressure in the unit’s connection hoses, otherwise, like me, you will have the unpleasant experience of the hose suddenly becoming detached from the unit … The light really is perfect for restorative dentistry and prosthetic preparations.
