What is dental odontogenesis?
Tooth development, or odontogenesis, is the process of tooth formation, eruption, and integration with its surrounding tissues.
Where are Ameloblasts located?
Ameloblasts are cells present only during tooth development that deposit tooth enamel, which is the hard outermost layer of the tooth forming the surface of the crown.
What are the different parts of a tooth germ?
The tooth germ is organized into three parts: the enamel organ, the dental papilla and the dental sac or follicle. The enamel organ is composed of the outer enamel epithelium, inner enamel epithelium, stellate reticulum and stratum intermedium.
What is the Bell stage?
(bel stāj) Third stage of tooth development, wherein cells form the inner enamel epithelium, the stratum intermedium, the stellate reticulum, and the outer enamel epithelium; the enamel organ assumes a bell shape.
What are the odontoblasts?
Odontoblasts are specialized cells that produce dentin and exhibit unique morphological characteristics; i.e., they extend cytoplasmic processes into dentinal tubules.
What is the difference between Amelogenesis imperfecta and dentinogenesis imperfecta?
Amelogenesis imperfecta vs. This is a bone-like substance that makes up the middle layer of your teeth. Dentinogenesis imperfecta is caused by mutations in the DSPP gene. People with dentinogenesis imperfecta have teeth that are translucent and blue-grey or yellow-brown in color.
What are the epithelial rests of Malassez?
In dentistry, the epithelial cell rests of Malassez ( ERM) or epithelial rests of Malassez ( pax epithelialis pediodontii) are part of the periodontal ligament cells around a tooth. They are discrete clusters of residual cells from Hertwig’s epithelial root sheath (HERS) that didn’t completely disappear.
Do the rest of Malassez play a role in periodontal ligament function?
Under certain stimuli, they may give rise to various types of odontogenic cysts and tumors (e.g., lateral periodontal cyst, radicular cyst, and squamous odontogenic tumor ). In addition, recent studies have suggested the rests of Malassez play an important role in normal periodontal ligament function and may participate in periodontal regeneration.
What is Malassez cyst?
It is considered that these cell rests proliferate to form epithelial lining of various odontogenic cysts such as radicular cyst under the influence of various stimuli. They are named after Louis-Charles Malassez (1842–1909) who described them.
