People who regularly radiographs the teeth are more likely to suffer from brain tumors, shows a study of American researchers published today in the journal American Cancer advises to avoid doing those exams annually, reports Agence France Presse (AFP).
The study, which is published in the journal published by the American Cancer Society, was led by Elizabeth Claus, of Yale University, and is based on data collected from 1433 U.S. patients aged between 20 and 79 years who were diagnosed tumors brain meningioma type, which is generally benign.
Patients who had made a radiographic to the teeth, thus having been subjected to x-rays were 1.4 to 3 times more likely to develop a meningioma, the study continues. Prevalence rates depended on the type of dental examination done, x-rays can be used in different strengths, and patient age.
The meningioma is a tumor that forms in the membrane that surrounds the brain. In most cases, these tumors are benign but grow quickly, can cause disability and induce fatal risks under certain conditions.
People who make dental radiographs are today exposed to less radiation than in the past, referred to AFP, but still, this study comes warn dentists and patients to rethink the reasons that lead to x-rays, says Elizabeth Claus.
The study offers an opportunity to be vigilant with regard to the use of x-rays to the teeth, as well as other risk factors can be mitigated, the researcher said.
It is noted that the American Dental Association (American Dental Society) recommends a dental exam done children every year or once every two years; adolescents is suggested to be done every 18 months to three years ; and adults every two to three years.
