Facts about Dental pulp
- 08
Calcium deposits accumulate in dental pulp tissue over time, with pulp stones forming in approximately 10 to 90 percent of teeth depending on age and tooth type.
- 07
Regenerative capacity in dental pulp allows stem cells to differentiate into odontoblasts and osteoblasts, enabling tooth repair and bone formation in response to injury or cavity preparation.
- 06
Inflammation of dental pulp increases intrapulpal pressure to levels exceeding 60 millimeters of mercury, causing severe pain because the rigid dentin walls prevent tissue expansion and fluid drainage.
- 05
Root canal therapy requires removal of infected dental pulp tissue, a procedure first successfully documented by Pierre Fauchard in 1728 as a method to save teeth from extraction.
- 04
Within hours of tooth extraction, dental pulp tissue undergoes necrosis due to disruption of its blood supply, as the pulp lacks collateral circulation and depends entirely on a single apical artery for oxygenation.
- 03
Pulp vitality in a tooth can be assessed using electrical pulp testing, which applies currents between 1 and 20 milliamps to detect neural response.
- 02
Odontoblasts, the specialized cells lining dental pulp, continuously produce dentin throughout life at a rate of approximately 4 micrometers per year.
- 01
The dental pulp contains approximately 200 to 300 nerve endings per tooth, making it one of the most sensitive tissues in the human body.
