Cutting with light

04.09.2003


More dentists, patients see benefit of lasers

Until recently, the use of lasers in the dental office was marginalized because of the cost of the equipment and its limited use. Today, manufacturers and dentists believe "cutting with light" will gain a much wider appeal thanks to recent technological leaps and declining costs, according to the August/September 2003 issue of AGD Impact, the monthly newsmagazine of the Academy of General Dentistry (AGD).

Not a day goes by that I don’t use it," Christopher J. Walinski, DDS, a Massachusetts-based laser dentist, says in the Impact article. "We have patients coming in who want to be treated with the laser. I’m the guy with the laser."



Lasers debuted in health care in the 1960s. They made their way into dentistry in the early 1990s. About 5 percent of U.S. practitioners use lasers.

"Basically new technology is the appeal for patients," says Eric Shapira, DDS, MAGD, spokesperson for the AGD. "Patients look for ease of having procedures done without major discomfort."

In addition to the number of soft- and hard-tissue procedures applicable to lasers, advocates say faster healing, improved infection control, reduced postoperative pain and sensitivity, reduced patient anxiety and less need for anesthesia or injections are advantages of the laser.

"Many procedures work without giving an injection, which is less stressful for dentists and patients," says Robert A. Convissar, DDS, FAGD, co-author of a report that will be published in the September/October 2003 issue of General Dentistry, the AGD’s clinical, peer-reviewed journal.

The laser industry, as it pertains to dentistry, is expected to grow. According to some manufacturers, lasers may soon be developed for removal, preventive cavities detection and using different wavelength to vaporize cavities beneath the tooth surface.

Laser Facts
  • "Laser" is an acronym for light amplification by stimulated emission of radiation.
  • A laser is an intense beam of monochromatic light used to do everything from "reading" compact discs to performing surgical operations.
  • Soft-tissue lasers work only on soft tissue, such as gums. Hard-tissue lasers work on tooth and bone.
  • The U.S. Food and Drug Administration has cleared five types of lasers for dental use: the carbon dioxide (CO2) laser, the Neodymium-Yttrium-Aluminum-Garnet (Nd:YAG) laser, the semiconductor diode laser and the erbium series of lasers, the Ebrium-Yttrium-Aluminum-Garnet (Er:YAG) and the Erbium-Chromium-Yttrium-Scallium-Gallium-Garnet (Er,Cr:YSGG).
  • CO2 and Nd:YAG lasers are used for soft tissue procedures, such as lesion removal and frenectomies.
  • Semiconductor diode lasers also perform many of the soft-tissue procedures of those lasers, in addition to bleaching.
  • Erbium lasers work well on soft tissue, but their unique contribution to high-tech dentistry is their ability to perform hard tissue procedures, including cavity removal and root canals.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
