The dental pulp is a specialized, nonmineralized, highly vascularized connective tissue occupying the central compartment of the tooth, distinct from surrounding mineralized tissues, including enamel, dentin, and cementum.[1] The pulp contains connective tissue, blood vessels, and nerves. This structure communicates with the periodontium through the apical and, in some teeth, accessory foramina. Completely enclosed by dentin, the pulp provides nutritive support, participates in dentinogenesis, and mediates immunologic defense, underscoring its essential role in maintaining tooth vitality and function. Detailed knowledge of pulp anatomy and physiology is critical for accurate diagnosis and treatment planning. Familiarity with this structure's vascular and neural architecture guides clinicians during pulpotomy, root canal treatment (RCT), and apical surgery, minimizing iatrogenic injury and preserving pulp vitality whenever possible. This insight also informs pain control, hemostasis, and prognosis assessment, ultimately improving tooth survival and patient outcomes.
