THE BIG PICTURE Dental digital radiography Background.—It is not just the ability to display filmless radiographs that makes dental digital radiography so significant. It is also the fact that those images are captured on computer and displayed nearly instantaneously, so that operative procedures can be guided by the images. In addition, digital images can be combined with film radiographs to enhance outcomes. A digital intraoralradiographic system, RadioVisioGraphy (RVG), is now available commercially. Professional Benefits.—Academic comparisons of the successive generations of intraoral digital x-ray detectors to film are only the beginning of exploring digital radiography. The 3-dimensional applications possible with digital imaging allow the practitioner to make treatment decisions based on accurate current information. These approaches are impractical with film. Rather than relying on baseline interpretation, maxillofacial treatment can be image guided. Three-dimensional models have been produced from computed tomographic datasets. Patient Benefits.—Patients, as well as dentists, benefit from the latest technologies. Data can be sent directly from a cone beam computed tomogram at the treatment site to
various vendors so they can construct guides for dental implant placement and make laser-generated models to plan oral surgery. Discussion.—Digital radiographic and visible light images lay a foundation for further technologies that will permit the dentist to become an architect of dental care.
Clinical Significance.—Instantly viewing images is but a first step in the digital revolution in radiology. Coupled with developments in computers, digital imaging can produce 3dimensional representations impossible with film. Rather than just providing snapshots, these images will guide treatment.

EXTRACTS NEW SENSOR COULD HELP CLEAR AIR WHEN IT COMES TO HALITOSIS Researchers in Japan have developed a device that can test human breath for halitosis. Twice as sensitive as the human nose, the biosensor or “sniffer” can measure methyl mercaptan in the breath. Methyl mercaptan is the chemical that is a significant factor in halitosis, a condition that can be a serious social detriment and a sign of medical or dental problems. The sniffer will not be immediately marketed for personal use, but dental hospitals will likely be the first to make use of the device, according to bioengineer Kohji Mitsubayashi of Tokyo Medical and Dental University. The research is detailed in the October-November Analyst, which is published by the British Royal Society of Chemistry. [Get a Whiff of This. AARP Bulletin, December 2005, p 23.]
