"Pulpal" is a term that relates to the pulp tissue of a tooth, which includes nerves and blood vessels. There are several synonyms that can be used to describe pulp, such as dental pulp, odontoblast, and pulp tissue. The dental pulp is the most known synonym used to refer to the living tissue inside a tooth. Odontoblasts, on the other hand, are cells that form and maintain the dentin of a tooth, which is a layer between the pulp and enamel. Pulp tissue is also synonymous with the dental nerve, which is responsible for transmitting sensory information from the teeth to the brain. These terms are useful when discussing tooth anatomy and dental procedures that involve the pulp.
