Pulp tissue, located in the center of a tooth, is a vital, soft tissue composed of nerves, blood vessels, and connective tissue, playing a crucial role in tooth vitality and sensory function. It is responsible for the formation of dentin and responds to external stimuli, such as temperature and pressure, which can affect dental health if it becomes inflamed or infected.
Odontoblasts are specialized cells located in the dental pulp responsible for the formation of dentin, a calcified tissue that forms the bulk of a tooth. These cells play a crucial role in tooth development and repair by secreting dentin matrix proteins and initiating mineralization processes.
Dentinogenesis is the process by which dentin, the hard tissue beneath the enamel of teeth, is formed by odontoblasts. This process is crucial for tooth development and involves a complex interplay of signaling pathways and extracellular matrix components to ensure proper mineralization and structural integrity of teeth.

Pulpitis is an inflammation of the dental pulp, often caused by bacterial infection due to decay or trauma, resulting in pain and sensitivity. It can be reversible or irreversible, with the latter requiring more extensive treatment such as root canal therapy to alleviate symptoms and prevent further complications.
Root canal therapy is a dental procedure aimed at treating infection or damage within the pulp of a tooth, thereby preserving the tooth structure and preventing further complications. It involves the removal of the infected pulp, cleaning and disinfecting the canal, and sealing it to prevent reinfection.
Dental pulp stem cells (DPSCs) are a type of mesenchymal stem cell found in the dental pulp of teeth, capable of differentiating into various cell types, including odontoblasts, osteoblasts, and neural cells. They hold significant potential for regenerative medicine and tissue engineering due to their ability to regenerate dental tissues and their immunomodulatory properties.
Pulp necrosis is the death of dental pulp tissue, often resulting from untreated tooth decay or trauma, leading to infection and potential abscess formation. It is typically asymptomatic in early stages but can cause severe pain and swelling as the necrotic tissue becomes infected.
Tooth sensitivity is a common dental condition characterized by discomfort or pain in teeth when exposed to certain stimuli like hot, cold, sweet, or acidic foods and drinks. It often results from enamel wear or gum recession, which exposes the dentin layer of the tooth, leading to heightened sensitivity.
The pulp chamber is the central part of a tooth's dentin that houses the dental pulp, comprising nerves and blood vessels essential for tooth vitality. Understanding its structure and function is crucial for dental procedures like root canals, which aim to treat infections or damage within this area.
Root canal anatomy refers to the internal structure of a tooth's root, encompassing the pulp chamber, root canals, and apical foramen, which are crucial for endodontic diagnosis and treatment. Understanding this complex and variable anatomy is essential for successful root canal therapy, as it guides the removal of infected tissue and the sealing of the root system.
The subodontoblastic plexus of Raschkow is a network of nerve fibers located beneath the odontoblast layer in the dental pulp, playing a critical role in transmitting sensory information, including pain. This plexus is essential for the tooth's response to stimuli and is involved in the sensation of dentinal pain, contributing to the overall sensory function of the pulp tissue.
