Abstract:
Current methods for diagnosis of pulpal pathosis are often inadequate and there is a need for an in vivo method to visualize dental pulp tissue. This report compares micromagnetic resonance imaging (MMRI) with routine H & E histology on a cross sectional view of a molar tooth. The extracted tooth was imaged with a Bruker AM-400 NMR spectrometer modified with a microimaging accessory. The tooth was then decalcified and sectioned at the same level as the MMR image. Image intensity readings were acquired for specific areas of the pulp chamber for comparison with histology. The results demonstrate that there is a close correlation between the MMRI and the low power H & E appearance of pulp tissue.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
