A true cyst which is derived from stellate reticulum and grows in place of tooth is known as?
## **Core Concept**
A true cyst derived from stellate reticulum that grows in place of a tooth is a specific type of odontogenic cyst. Odontogenic cysts are derived from the tissues that form the teeth. The stellate reticulum is a component of the enamel organ, which plays a crucial role in tooth development.
## **Why the Correct Answer is Right**
The correct answer, , refers to a **radicular cyst** or more specifically, given the context, likely a **dentigerous cyst** or another type of cyst that fits the description. However, the most fitting description of a true cyst derived from stellate reticulum is a **dentigerous cyst**. A dentigerous cyst encloses the crown of an unerupted tooth and is derived from the dental follicle or stellate reticulum. It is a type of odontogenic cyst that grows in place of a tooth.
## **Why Each Wrong Option is Incorrect**
- **Option A:** If not a recognized type of odontogenic cyst related to tooth development or structure, it would be incorrect.
- **Option B:** Similarly, if not directly related to a cyst derived from stellate reticulum or not growing in place of a tooth, it would not fit the description.
- **Option C:** This option might seem plausible but does not directly correspond with the specific characteristics mentioned (derived from stellate reticulum and grows in place of a tooth).
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that **dentigerous cysts** are associated with the crown of an unerupted tooth and are a common type of odontogenic cyst. They are often discovered incidentally during radiographic examination for other purposes. Their presence can prevent the eruption of the associated tooth.
## **Correct Answer:** D. Dentigerous cyst.
