It is a message that has response in many clinics and hospitals. But there is a busy place where it has not: the dentist's Office.
Not only do most dentists still antiquated X-ray film, require higher amounts of radiation to use, but a new scanning device that emits more radiation than conventional methods are comprehensive dentists and other specialists an investigation by the New York Times has found.
Designed for dental offices, the device offers a cone-beam CT scanner, brilliant 3-d, called pictures of teeth, roots, and even skulls. This technology is a sure way for Orthodontists and oral surgeons to work with greater precision and to identify problems that could otherwise unnoticed go to tell his supporters.
But there is little independent research to verify these claims.Instead was the cone beam's popularity by misinformation about its safety and efficacy, some dentists paid or sponsored by manufacturers, lectures, seminars and training classes type, as well as through industry-sponsored magazines and conferences, according to the records and dozens of interviews with dentists and researchers from partially fueled.
Last month, the allowed Journal of the American Dental Association of a cone beam leader, Imaging Sciences International, a problem entirely dedicated to Cone Beam technology draw.This journal club, 150,000 dentists sent containing a favourable article by an author a cone beam CT with an airport scan identified say hat.In of fact a cone beam hundreds of times more radiation can generate, expert.
Cone beam CT scans can help dentists affecting implants, with complex cases where teeth and other serious problems befassen.Aber many experts in dental radiation alarms about what you, as their indiscriminate use see caused.Get sure that with a few directives or regulations, well-meaning not fully understand a new technology to dentists and other specialists turn that patients at risk, particularly younger.
Some Orthodontists cone beam scans of CT, now use all patients, screen, although a number of dental groups in this country and in Europe question, whether the advantage of routine use warrants the extra risk.
"All these different cone-beam CT-scanner to a world came out, which was unprepared,", said Keith Horner, Professor of oral radiology at the University of Manchester in the UK, study of the cone beam scanner for the European Commission coordinates."You're just pushed out there from manufacturers with the message, a 3D image is always better than a 2-D image, and that not be the case."
A popular new brand of braces has helped sell cone beam, because 3D images, requires doctors get either a cone beam scanner with radiation or a digital camera without it verwenden.Viele of Orthodontists opt for radiation, because it is faster.
The troubled by widening using cone beam technology acknowledge that by itself, the risk of a single scan is relatively small.But patients often get more than a scan, and lifetime risk rises with each Belichtung.Ohne clear benefits say there are at risk.
"To me a question to the mother of a potential orthodontic patients," said Dr. Stuart C. White, former Chairman of oral radiology at UCLA School of dentistry."You want me to use a tool that is quite sure - a camera - record where of your child's teeth or other method that can rarely cause cancer so that we can save time?"
The cone beam business is lukrativ.Eine industry for manufacturers and dentists to estimate were sold more than 3,000 scanners and about 30 different models at prices up to $250,000.
"Dentists who some of which several hundred dollars per scan free benefit by owning their own machines.""More profit per unit of time Chair," Imaging Sciences, cone beam manufacturers promises.
Marketers boost interest in the technology by holding drawings for free cone-beam CT scanner and other Geschenke.Ein State Washington Orthodontists, who a online lecture was sponsored by Imaging Sciences, offers dentists coupons of free scans for your patients as a way to make recommendations to create.
And then there's the "wow" factor, Dr. Terry Sellke said an Orthodontists in Illinois.
"" To see kids love on the 3-d image", Dr. Sellke said in a webcast of Imaging Sciences sponsored.""You can go in our computer and see your skull.""Another Orthodontists discussed skull in green and purple coloring 3-d."He said "Fun for the children".
Dr. Allan G. Farman, President of American Academy of oral and Maxillofacial Radiology, warns doctors not to overly in love, the new technology, citing the example how shoe stores once took to see feet X-rays of the customer if the shoes fit.
"At least the shoe merchants were ignorant about the effects of radiation," said Dr. Farman.
