The document discusses the anatomy and physiology of the tooth pulp. It describes the different tissues that make up the tooth, including enamel, dentin, cementum, gingiva, alveolar bone and the periodontal ligament. It then focuses on the dental pulp, explaining that it is made of highly vascular connective tissue located inside the tooth. The document outlines the different cell types in the pulp and its blood supply. It also discusses the innervation of the pulp and the different types of sensory nerve fibers present.
