Effects of magnetic resonance imaging (MRI) on the formation of mouse dentin and bone

Abstract

The effects of magnetic resonance imaging (MRI) on dentin and bone formation in mice were examined using standard autoradiographic and liquid scintillation procedures. It was observed that exposure to a standard 23.2 min clinical multislice MRI (0.15T) procedure caused a significant increase in the synthesis of the collagenous matrix of dentin in the incisors of mice. There were no significant effects on alveolar and tibial bone matrix synthesis. These results suggest that the magnetic fields associated with MRI can affect the activity of cells and/or tissues that are involved in rapid synthetic activity.

“…Prato et al (1990Prato et al ( , 1994) discovered a significant increase in the permeability of the blood brain barrier. Kwong-Hing et al (1989) examined the acute exposure effects of a 0.05 T MRI on dentin and bone formation in mice. They found that the exposure caused a significant increase in the synthesis of the collageneous matrix of dentin in the incisors.…”
