|
What is the definition of a cyst?
|
A cavity (pathologic, often fluid-filled) that is lined by epithelium
|
|
|
What are two sub-classifications of odontogenic cysts?

|
What should be your #1 differential if you see an Impacted Tooth with a radiolucency associated with the crown of the impacted tooth?
|
Dentigerous Cyst (Follicular Cyst)
|
|

Which group of people are most commonly affected by Dentigerous (Follicular) cysts?
|
20's-30's
Males Whites Mandibular 3rd Molars > Maxillary canines (Involves teeth that are most commonly impacted) |
|
|
What complications can arise with a dentigerous cyst?
|
1. Unicystic ameloblastoma
2. Mucoepidermoid carcinoma (There are cells present that have the ability to produce both mucous cells and epidermal cells) Squamous cell carcinoma from the cystic epithelium (very rare) 3. |

True
|
|
|
How do Dentigerous (Follicular) cysts appear radiographically?
|
1. Unilocular radiolucent area associated with the crown of an unerupted tooth (Cavity lined with epithelium usually with some fluid inside)
2. Well-defined, Sclerotic Border 3. Higher rate of rooth resorption than in anye other odontogenic cyst 4. Radiolucency should be at least 3-4 mm for it to be a dentigerous cyst |
|
|
What is the difference between a lateral periapical cyst and a lateral periodontal cyst from a clinical perspective?
|
Vitality of the tooth
Lateral periodontal cyst the tooth is Vital |
