Dental Pulp
The neurovascular connective tissue occupying the central pulp chamber and root canals of a tooth, responsible for dentine formation, nutrition, and sensory function.
Full Definition
The dental pulp is a loose connective tissue containing blood vessels, lymphatics, nerve fibres, fibroblasts, and odontoblasts lining its periphery. It originates from dental papilla during tooth development and persists throughout the life of the tooth. Clinically, pulp vitality is assessed using thermal or electric tests and determines the endodontic management pathway. Editors must distinguish between 'pulp chamber' (the coronal portion) and 'root canal' (the radicular extension), as these anatomical terms carry precise implications in endodontic reports and operative notes.
Usage
Usage note: 'Pulp' should not be used as a synonym for 'pulp chamber' or 'root canal system'; each term refers to a distinct anatomical concept in endodontic documentation.
