Mr Roy Herren

Thank you for sending this important news update. You may be aware of the fact that conventional dental equipment is getting replaced by 
conebeam CT. This is happening in India. This shift in practice is 
likely to have an impact on radiation exposures.

In this context, I would like to receive the view of the list members on a specific aspect.  Namely endorsement of a specific product by the 
specialists. Is there a written norm or law against such endorsement? 

In India, the office bearers of the Indian Medical Association were 
penalized by the Medical Council of India for endorsing two food 
products marketed by a multinational company.If I recall correctly the 
name of two important office bearers were withdrawn from the medical registry for six months for the indescretion

While I was surfing for some details of conebem CT equipment I came across the following in a new release

"Joseph M. Caruso, DDS, MS, MPH - Associate Dean, Strategic Initiatives
and Faculty Practices, Professor and Chair Orthodontics and Dentofacial
Orthopedics at Loma Linda University School of Dentistry stated, "Over the
years we have had an opportunity to evaluate, use and research many different
manufacturers; however our main choice for patient use is still the NewTom. The
supine machine provides improved patient stability, with less motion artifacts,
allowing us to continue to provide more complete diagnosis to our orthodontic,
implant and Sleep Apnea patients. We upgraded to the 3G several years ago.
After 10 years of day-in and day-out use and thousands of scans, we will
replace our NewTom 3G with what I believe provides the best images and
radiation protection to the patient in the industry - the NewTom 5G. It features
more fields of view (FOV), less radiation, a voxel size of .075mm, and
unsurpassed image clarity. With over 40 machines on the market NewTom was still
our choice. It's not just a machine, it's a relationship."

Is there anything amiss?

I shall greatly appreciate the comments of the list members on the ethical and legal dimensions of such an endorsement.

Subject: [ RadSafe ] Frequent dental X-rays linked to most common brain tumor
As luck would have it I had my annual dental X-rays just this afternoon.

Frequent dental X-rays linked to most common brain tumorApril 10, 2012 in Cancer 

People who received frequent dental x-rays in the past have an increased risk of 
developing the most commonly diagnosed primary brain tumor in the United States. 
That is the finding of a study published early online in Cancer, a peer-reviewed 
journal of the American Cancer Society. Although dental x-rays are necessary in 
many cases, these findings suggest that moderate use of this form of imaging may 
be of benefit to some patients.
