dental anatomy - 3 Questions
Sometimes, mineralization of dentin begins in small globular areas that fail to coalesce into a homogenous mass. This results in zones of hypomineralization between the globules. These zones are known as globular dentin or interglobular spaces. Thus, demonstrating defect of mineralization and not of matrix formation, the dentinal tubules pass uninterruptedly through interglobular dentin.
In the case of primary teeth, the roots are often resorbed as the permanent teeth develop. The facial aspect of the root tends to be the last area to undergo resorption due to its position and the way the succedaneous tooth exerts pressure. The facial root surface is generally more stable and remains attached to the gingiva longer than the other aspects, making it the longest and most securely attached during extraction.
