What dental journals can we trust?
To be improved on later.
Science based medicine is a nice website with many articles trying to eliminate the emotional and irrational side of the human thought process. The dentistry section is linked but there is good stuff on over screening in general. It’s human nature to see x test show or find some awful result and thus think everyone should be screened with x test. However, the minimal hazard, danger, damage, and financial cost are rarely properly considered. Larger field X-ray screenings are common in dentistry since they can rarely turn up something bad but the reality is even small amounts of radiation does eventfully cause cancer, especially in susceptible people. Cancer screenings and some of the issues with them are discussed on the same site, in particular I like this article about screening without symptoms.
