Pulp (tooth)
Pulp (tooth)
The pulp of the tooth is the innermost part of the tooth, composed of living connective tissue and cells called odontoblasts. The pulp is a highly vascularized and innervated tissue, playing a crucial role in the health and function of the tooth.
Anatomy[edit | edit source]
The pulp is located in the center of the tooth and extends from the crown to the roots. It is divided into two main parts: the coronal pulp within the crown, and the radicular pulp within the roots. The pulp communicates with the periodontium through the apical foramen at the tip of the roots.
Function[edit | edit source]
The pulp has several functions, including sensory perception, tooth nutrition, and tooth development and eruption. It provides the tooth with the ability to sense temperature, pressure, and other stimuli. The pulp also supplies nutrients to the tooth through its blood vessels and aids in the formation of dentin.
Clinical significance[edit | edit source]
Damage or disease of the pulp can lead to pulpitis, an inflammation of the pulp. This can cause severe toothache and sensitivity. If left untreated, pulpitis can progress to pulp necrosis and dental abscess. Treatment options include root canal therapy, where the diseased pulp is removed and replaced with an inert material.
