What types of lasers are there?

Various types of lasers are used in dentistry. On the one hand there are large and expensive Er:YAG (specialist for hard tissue applications), Nd:YAG (specialist for bacterial reduction) and CO2 lasers (specialist for surgery) which, due to their design, have less flexible mirror arm systems, complex cooling mechanisms and relatively long start-up times. On the other hand there are compact and more cost-effective diode lasers with a wider range of applications, e.g., for minimally invasive surgery, bacterial reduction in periodontology and endodontics as well as low-level laser therapy.

That's why we at Dentsply Sirona opted for diode lasers from the word go.

Depending on the laser wavelength and the tissue composition, various physical interactions are induced:


Furthermore, with diode lasers one can differentiate between hard and soft lasers. Hard lasers trigger a direct reaction with the tissue through absorption. They are used in surgery for bacterial reduction. Soft lasers do not trigger a direct reaction with the tissue, instead acting at the cellular level deep inside tissues. They are used for pain therapy and photodynamic therapy.


How does a diode laser work?

The wavelength of a laser is a product of the medium with which the laser is generated – crystal, gas, or, as with diode lasers, a semiconductor. The applications for which a laser can be used depend on the wavelength which, in turn, determines the absorption, i.e., the reaction of the light with the tissue. That is, the laser’s energy is transferred to the tissue.

diode laser

  • 445 nm:
    outstanding cutting performance due to very high absorption in hemoglobin - even at lower power. Due to the fact that absorption is lower in water, correspondingly less heat develops in adjacent tissue.
    660 nm:
    for ‚soft laser‘ applications such as LLLT or biostimulation.
    970 nm:
    germ and bacteria reduction in Periodontology and Endodontics.
  • 970 nm:
    germ and bacteria reduction in Periodontology and Endodontics, surgical procedures.
  • 810 nm / 940 nm
    Wavelengths currently coming to clinical use in other dental diode lasers.
Why should you choose a diode laser or the SIROLaser Blue?
  • Diode lasers are very versatile. If we compare the areas in which the various kinds of lasers can be used, it quickly becomes obvious that diode lasers cover the widest range of treatments. The SIROLaser Blue comprises the complete spectrum of hard and soft lasers. In particular it impresses with its outstanding cutting efficiency through use of the 445nm wavelength.
  • Diode lasers are small, convenient and cost-effective devices which can be used flexibly and portably within your practice. The SIROLaser Blue is both extremely easy and intuitive to operate and stands out thanks to its exceptional design.

Users report on the SIROLaser Blue

1st Sirona Laser Days
09.-11.10.2014 in Bensheim, Germany

The main focus of the 1st Sirona Laser Days was the introduction of the blue wavelength for dental use. Fundamental feedback was collected from the participants to guide the R&D process and to prepare for the launch of SIROLaser Blue at IDS 2015.

At the Sirona Laser Days well-experienced laser practitioners and leading scientists of laser dentistry discuss and share their knowledge and experiences to make lasers more popular in dentistry.


Statements in original voice:

“The SIROLaser Blue very effectively reduces the microbial load. I always use the laser for root canal treatments and now need much fewer follow-up treatments of recurrent inflammations. My patients think that’s wonderful, of course.”

Dr. Matteo Iaria, Italy

“The SIROLaser Blue is very easy to handle and has really practical features and a wide range of uses. I need only one device for all laser applications and can cut more quickly and efficiently thanks to the blue wavelength. My patients are also delighted because wounds heal faster, they have less postoperative pain, and consider the treatment to be much more modern.”

Prof. Dr. Giovanni Olivi, Italy

“Finally no more stitches. In my practice, I treat a large number of children—they not only think it’s great that they no longer need stitches and have less pain, they also think the laser treatment is pretty exciting.”

Dr. Isabelle Nguyen, France

“The SIROLaser Blue is really practical because it is quite compact and thus easy to handle. It’s operation is also almost self-explanatory. The laser is quick to set up. The blue cutting performance is simply phenomenal and it makes my work even more efficient.”

Dr. Simone Suppelt, Germany

“Previously, I used to say that I could never manage without my CEREC. Now I say that I could never manage without my CEREC and my laser. I use the laser for almost every treatment.”

Dr. Michael Maier, Germany

“Blue laser technology is an alternative to conventional techniques. Unlike when using a scalpel, severe bleeding can be prevented. And with the blue laser, we have more control over heat development than with the electrotome.”

Dr. Mariana Petrone de Moraes, Sweden

2nd Sirona Laser Days
08.-10.10.2015 in Brescia, Italy

The key topics of the 2nd Sirona Laser Days were the information about the current state of research and the concrete practical experiences at the clinics of the international customer trial of the SIROLaser Blue.

At the Sirona Laser Days well-experienced laser practitioners and leading scientists of laser dentistry discuss and share their knowledge and experiences to make lasers more popular in dentistry.

Find more about the event and the infinite possibilities of SIROLaser Blue in Marlene Hartinger’s article (Editorial Journalist Oemus Media).

Statements in original voice:

“As far as surgery is concerned, I cannot think about going back to the past. For example, we have decided to abandon the electrosurgical scalpel and only use the SIROLaser Blue from now on.”

Dr. Elena Rosina, Italy

“You should have for every general practitioner a laser in the clinic. This is like an ABC for the language. I cannot work without the laser and definitely after trying the blue laser (SIROLaser Blue) I cannot work without it.”

Prof. Dr. Ahmed Adel AbdelHakim, Egypt

“I think that the no contact system in particular can be quite useful in the workflow because of not having to touch tissues and probably being able to regulate the amount of energy applied. You ask whether I can picture myself working with it? Yes! I hope to soon have it at home and be able to start working with it. Yes, I would like that.”

Dr. Rodrigo Pino Conrads, Chile

“I feel really privileged to be one of the first SIROLaser Blue users. As I am already familiar with the previous model I can judge the new laser more objectively. I don´t have to rely on reports or articles that may have been made under unrealistic user circumstances or are just not applicable. I could no longer imagine working without a laser anymore - especially not without the SIROLaser Blue.”

Dr. Tristan M. W. Schiele, Germany

“To me biostimulation is the next main topic for laser dentistry. It will gonna change how we perform and how we view that tissue will heal and at the same time how we can help people get healthier.”

Dr. Weng Cheu Yue, Singapore

“The hemostasis was what really impressed me. I will definitely not be going back to all the old-fashioned techniques that we used to use.”

Dr. Carlos Sfeir, France

“I tried the 455 nm wavelength and I see that the interaction of the laser to the tissue is very strong and I am impressed. I am honored that Sirona has invited me to the Sirona Laser Days. Out of curiosity I would like to find out what is happening in laser meetings worldwide.”

Dr. Kenneth Luk, Hong Kong

Additional statements in original voice about SIROLaser Blue

“In comparison with conventional diode lasers, the SIROLaser Blue benefits from the blue wavelength - it can be used in non-contact mode. My personal experience using the SIROLaser Blue has always been positive.”

Dr. Tariq Sultan, Germany
