Abstract
To assess whether it is possible to measure tooth vitality using magnetic resonance imaging (MRI). Signal intensity measurements were conducted using T(1) and T(2) sequences at the region of interest in 211 teeth (35 patients). Clinical findings showed that 17.3% of the teeth were avital, whereas 82.7% were found to be vital. Neither the T(2) sequence nor the non-contrast-enhanced T(1) sequence showed significant differences between vital and avital teeth. However, the contrast-enhanced sequence and, in particular, a comparison of signal intensities between the non-contrast-enhanced T(1) sequence and the contrast-enhanced sequence showed a significant difference between vital and avital teeth. Contrast-enhanced MRI enables us to draw conclusions on pulpal perfusion in vivo.Keywords
