Using 1and 31P Magnetic Resonance Imaging (MRI), microimages of teeth wereobtained with a silent Single Point Imaging (SPI) technique. Utilizing sine-shaped gradient ramps significantly reduced the sound pressure level of the experiment. 1H NMR showed distinct resonances from dentin and enamelwith a large difference in spin-spin and spin-lattice relaxation times. 3Dreconstruction of the data allowed for complete visualization of the object.
