Questions and Answers

What distinguishes a cyst from a pseudocyst?

A cyst is lined by epithelium, while a pseudocyst is not.

Name three types of inflammatory periodontal cysts.

Apical, lateral, and residual cysts.

What are the categories under odontogenic cysts?

Odontogenic cysts are classified into inflammatory and developmental types.

Describe the odontogenic keratocyst and its classification.

The odontogenic keratocyst is classified as a primordial cyst and is known for its aggressive behavior and high recurrence rate. Signup and view all the answers

What are the characteristics that define a cyst, and how does it differ from a pseudocyst?

A cyst is a pathological cavity lined by epithelium and contains fluid or semi-fluid material, while a pseudocyst is not lined by epithelium. Signup and view all the answers

Explain the difference between inflammatory and developmental periodontal cysts.

Inflammatory periodontal cysts arise due to inflammation, including types like apical, lateral, and residual, whereas developmental cysts include lateral developmental cysts and gingival cysts of adults and newborns. Signup and view all the answers

Identify and describe the types of dentigerous cysts.

Types of dentigerous cysts include central, lateral, and circumferential, which are characterized by their location relative to an unerupted tooth. Signup and view all the answers

What lesions are classified under odontogenic keratocysts, and why is this classification significant?

Odontogenic keratocysts include primordial cysts and keratocysts, and their classification is significant due to their aggressive nature and potential for recurrence. Signup and view all the answers

List the types of gingival cysts and briefly explain each type.

The types of gingival cysts are the gingival cyst of adults and the gingival cyst of newborns (Bohn's nodules); adults' cysts are typically associated with the gingival margin, while newborns’ cysts are small localized nodules in the alveolar mucosa. Signup and view all the answers

What is the main difference between developmental and inflammatory periodontal cysts?

Developmental periodontal cysts arise during tooth development, while inflammatory cysts result from the inflammation of the periodontal tissues. Signup and view all the answers

How are dentigerous cysts classified, and what is their primary association?

Dentigerous cysts are classified as central, lateral, and circumferential, and they are primarily associated with the crowns of unerupted teeth. Signup and view all the answers

What types of cysts fall under the odontogenic keratocyst classification, and why is this classification important?

The odontogenic keratocyst includes primordial cysts and keratocysts, and this classification is important due to their aggressive behavior and higher recurrence rate. Signup and view all the answers

Describe the gingival cysts of adults and newborns and their clinical significance.

Gingival cysts of adults are benign cysts in the gingiva, while Bohn's nodules in newborns are small cysts found in the oral mucosa, both requiring observation for complications. Signup and view all the answers

Identify the three types of inflammatory periodontal cysts and their underlying causes.

The three types of inflammatory periodontal cysts are apical, lateral, and residual cysts, caused by infection and inflammation of the dental pulp or surrounding tissues. Signup and view all the answers

What are the primary differences between inflammatory and developmental odontogenic cysts?

Inflammatory odontogenic cysts arise due to inflammatory processes, whereas developmental odontogenic cysts arise from abnormal growth or development of odontogenic epithelial cells. Signup and view all the answers

How does the classification of dentigerous cysts reflect their association with teeth?

Dentigerous cysts are classified as central, lateral, and circumferential based on their position relative to an unerupted tooth. Signup and view all the answers

What distinguishes the gingival cyst of adults from that of newborns?

The gingival cyst of adults typically occurs in the mandibular region in adults, while the gingival cyst of newborns, also known as Bohn's nodules, appears in infants on the alveolar ridge. Signup and view all the answers

What role do odontogenic epithelial cells play in the formation of odontogenic cysts?

Odontogenic epithelial cells are responsible for the development of various odontogenic cysts by proliferating and forming cavities lined with epithelium. Signup and view all the answers

Can you explain what a primordial cyst is and how it differs from other types of odontogenic cysts?

A primordial cyst arises from the degeneration of a tooth follicle and is formed in the absence of a prior tooth. It differs from other odontogenic cysts in its origin and pathogenesis. Signup and view all the answers
