People who underwent frequent dental x-rays in the past before radiation doses were lowered may be at greater risk of a usually benign form of tumor in the lining of the brain.

The latest research does not definitely link dental x-rays to brain tumors.

This type of benign tumor affects about 1 percent of the population.

This study in the journal Cancer suggests that dental x-rays could be a risk factor for these types of tumors called meningiomas.

The American Dental Association says the interviews in this study relied on patients' memories of how often they had different types of x-rays years earlier.

Scientists say the study suggests that patients should talk to their dentist about the possible dangers of x-rays.
