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.
