Where do odontoblasts differentiate from?
Mesenchymal tissue
What tissue gives rise to the Rests of malassez?
Hertwig's Epithelial Root Sheath
What tissue is most often responsible for the formation of apical periodontal cysts?
Rests of Malassez
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?
Developmental Odontogenic cysts
Inflammatory Odontogenic cysts
What is the most common odontogenic cyst?
Periapical (radicular) cyst
Lateral Radicular cysts are found on Non-vital teeth
Lateral Periodontal Cysts occur on VITAL teeth
What are the most common Developmental Dentigerous Cysts?
Dentigerous 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?
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)
Dentigerous (Follicular) cysts are True cysts
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
