Definition
dental anatomy
Dentin is a calcified tissue that forms the bulk of a tooth beneath the enamel and surrounding the pulp. It is harder than bone but softer than enamel, making it an essential component in the structure of teeth. Dentin is made up of microscopic tubules that allow for the transmission of signals, which can include pain. This tissue is not as resistant to decay as enamel but plays a crucial role in tooth sensitivity and health.
Synonyms
dental tissue, tooth tissue.
Examples of usage
- Dentin helps protect the pulp of the tooth.
- When a tooth decays, the dentin is usually affected first.
- Sensitive teeth often have exposed dentin.

Origin of 'dentin'
The word 'dentin' originates from the Latin word 'dentis', which means 'tooth'. The evolution of this term is rooted in the study of oral anatomy, where early medical texts identified the layers of teeth. Dentin was distinguished from enamel, the outermost layer, as research on dental structures advanced. By the 19th century, the study of teeth became more systematic, leading to the formal adoption of the term dentin in scientific literature. As dental research progressed, understanding the properties of dentin became essential for improving dental health and treatment techniques.
