Which part of dentine is the most mineralized?

The most mineralized part of dentine is known as peritubular dentine. This area surrounds the dental tubules and is characterized by a higher concentration of minerals compared to other types of dentine. The increased mineralization in peritubular dentine contributes to its greater rigidity and strength, which is essential for supporting the structural integrity of the tooth.

In contrast, intertubular dentine, while also mineralized, has a slightly lower mineral content than peritubular dentine. This type of dentine makes up the bulk of the tooth structure and is found between the tubules. Interglobular dentine is another form that exhibits areas of hypomineralization, making it less mineralized than both peritubular and intertubular dentine. The option suggesting that there is no significant difference in mineralization among these types does not accurately reflect the observed gradations in mineral content. Thus, peritubular dentine is recognized as the most mineralized component of dentine, contributing to its unique properties and functionality within the dental structure.
