The study reported an association between dental radiographs and
an increased risk of meningioma, a benign brain tumor arising in
the brain. The statement, written on behalf of the AAOMR by
Ernest Lam, DMD, PhD, University of Toronoto Faculty of
Dentistry, and Jie Yang, DDS, MS, Temple University Kornberg
School Dentistry: This population-based case control study
included almost 2,800 subjects, aged 20 to 79, located at
various centers throughout the U.S. Subjects were asked to
recall their frequencies of dental radiographic examinations
during four age-periods: younger than 10 years of age, between
ages 10 and 19, between 20 and 49 years, and older than 50 years
of age. The researchers reported an increased risk of meningioma
in individuals who received bitewing radiographs on one or more
occasions per year in all age groups under 50 years of age.
Subjects who received a panoramic examination were reported to
be at an increased risk for meningioma if they were exposed
under 10 years of age. No increased risk
