In very many human and veterinary texts, dentine and pulp is described under separate headings. Even though this might aid the understanding of the different components, structures and function of these two structures, it is crucial to understand that these are the two components/aspects of a single organ, the Dentine-Pulp Complex. During this presentation we will discuss in more detail the embryonal development of the pulp and subsequent induction of dentine production. The understanding the embryonal relationship between these two components will help to understand the response to injury. We will we will explore the anatomy of this organ in detail with special emphasis on:
• Odontoblasts and their odontoblastic processes
 • Dentinal tubules and dentinogenesis
 • Innovation with nerve endings situated between odontoblast and extending along with the odontoblastic processors into the dentinal tubules
• Other structures within the pulp involved in the support of odontoplasts to continue their work.

 We will consider the different types of dentine i.e. primary, secondary, and tertiary dentine as well as preparative versus reactive dentine. With this understanding we will consider the implications of enamel, enamel-dentine, and enamel-dentine-pulp fractures and the various diagnostic approaches and treatment options when confronted by trauma or other conditions affecting the teeth of our patients. We will discuss in detail:
• Sealing of exposed dentine
• Restoration
• Endodontic therapy vs. Extraction
• Vital pulp therapy.
