What is the meaning of Dentin?
Dentin is widely used term in Dental Anatomy.
Dentin, in dental anatomy, refers to the hard tissue that forms the majority of the tooth structure beneath the enamel and cementum. It is a calcified tissue that surrounds the dental pulp and supports the enamel and protects the pulp. Dentin is comprised of a matrix of collagen fibers and mineralized crystals, primarily hydroxyapatite. It is slightly softer than enamel but still very durable. Dentin contains microscopic tubules that extend from the pulp towards the outer surface of the tooth. These tubules house the odontoblasts, which are responsible for dentin formation and sensitivity. Dentin plays a crucial role in tooth function and provides structural support to the tooth, aiding in chewing and protecting the underlying pulp from external stimuli.
