Erosion of the non-occlusal surfaces of sheeps' deciduous teeth

Abstract:
Major erosion of the labial or lingual surfaces was seen in histological sections of deciduous teeth from three of 208 sheep from two farms. In one, the erosion extended through both the enamel and the dentine and thus exposed the pulp cavity which had developed pulpitis. In the other cases the erosion affected the cementum and dentine of the tooth root, and did not penetrate as far as the pulp cavity. Dentine proliferation occurred on the adjacent pulpal surface, however, although pulpitis was not evident.

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.
