Of the four types of dental x-rays, only the full-mouth series was associated with this increased risk. More specifically, the risk was elevated with the aggregate number of full-mouth series in 10-year periods from approximately 15–40 years before diagnosis, with significant elevations in the 10-year periods beginning 22–30 years before diagnosis. The risks in these analyses were even greater when only women were considered.
One needs to be aware that radiation exposure from full-mouth series was much greater in the past than it is now and as such, this risk may be nominal (though not zero) with current dental x-ray technology.
However, it also should be a reminder that x-rays should not be routinely performed unless there is a very good reason to obtain especially in children who are more susceptible to radiation injury... and that applies to not only x-rays, but any kind of testing involving ionizing radiation including CT scans.
Some x-rays should NEVER be performed including sinus x-rays for sinus problems given a nearly 50% error rate in diagnosing the presence OR absence of sinus problems.
X-rays for nasal fractures is not recommended given x-rays rarely change how such fractures are managed.
Soft-tissue lateral x-rays to look for large adenoids should also be discouraged as nasal endoscopy can provide similar if not better information without any radiation exposure.

This page appears to get a good ammount of visitors. How do you advertise it? It offers a nice individual
twist on things. I guess having something authentic or substantial to talk about is the most important thing.
