What are the cells lining the inner aspects of the dentin wall called?

The cells lining the inner aspects of the dentin wall are called odontoblasts. These specialized cells are responsible for the formation and maintenance of dentin, which is the hard tissue that lies beneath the enamel in teeth. Odontoblasts play a crucial role in the dental structure by producing dentin matrix and secreting enzymes for its mineralization. They are located in the dental pulp at the outer boundary and have long processes that extend into the dentinal tubules, helping to maintain the vitality of the tooth and respond to external stimuli.

While osteoblasts are related to bone formation, chondrocytes are involved in cartilage formation, and ameloblasts are responsible for enamel production, none of these cell types are involved in the lining of the dentin wall. This makes odontoblasts the correct choice, as they specifically relate to the formation and maintenance of dentin.
