Age: Any age but more often between 30-50
Site: Posterior mandible but can be anterior, 50% associated with impacted teeth
Appearance: They are unilocular, expansive, well defined, and can have flecks of RO material like driven snow or a multilocular honeycomb appearance, and can be mixed but they are uncommon. Make amyloid
TX- resection
Central Giant Cell Granuloma/CGCG
Ill-defined, single, multi
Patient: Females
Age: Young 60% children and adults below 30
Site: Mandible often anterior and cross midline
Appearance: Multilocular expansile RL with wispy septa, can be aggressive, ballooning
TX: Curettage, possible resection, steroids
Central Odontogenic Fibroma
Chapter 2
Well- defined- single, multi or uni, usually RL
Patient: Females 7 to 1
Age: Average age of 40 or children depend on the resource
Site: More in the anterior maxilla 60% but has been seen in posterior mandible 40%
Appearance: Unilocular or multilocular expansile RL or rarely 12% R with flecks of RO material.
TX: Curettage
COF/Central Ossifying or Cementifying Fibroma
Chapter 2
Defined, single, multi or uni
Patient: Females 5:1
Age: Average 35
Site: 90% in mandible
Appearance: Fast, Expansive in all directions, can displace teeth, resort, corticated border with RL or RL with RO in it. Go through 3 stages starting out RL and moving into mixed then turning RO. Characteristically cause a dip in inferior border of the mandible.
TX- Surgical excision or curettage and enucleation
Chondroma
Ill-defined
Patient: Any- rare
Age: Any- rare
Site: Condyle of anterior maxilla midline only
Appearance: Irregular RL or mottled RD, non-painful, firm, smooth or lobulated submucosal mass
TX: Surgery/Excision
Chondrosarcoma:
Ill-defined Patient: Males Age: Older average 60s Site: More in the maxilla Appearance: Unilocular or multilocular expansile buccal lingually, RL mixed snowflake or punctate calcified foci. Can cause teeth to be non-vital. TX: Curretage
Dentigerous Cyst
Chapter one
Defined, single
Patient: No gender preference
Age: Most common 20-30
Site: Posterior mandible is most common- Often associated with impacted 3rd molar- associated with the crowns of teeth or max canines
Appearance: Unilocular or multilocular radiolucency often with corticated borders. Can be aggressive, expansile and displace teeth and resorb roots or not and they are pretty common- 20% of odontogenic cysts. Like unerupted teeth.
TX: curettage to marsupialization
Recurrence is rare
Exostosis
Well-defined, multiple or single
Patient: Any gender
Age: Any age- associated with mechanical irritation
Site: Maxilla more common- often bilateral, molar area buccal and posterior alveolar ridge
Appearance: Radiopaque mass- this could be superimposed and not internal in the bone.
Fibrous Dysplasia
Ill-defined, can be multiple
Patient: No gender
Age: Starts at puberty and completes growth by 30
Site: More common in maxilla, but can also occur in mandible
Appearance: Asymptomatic swellings that can displace teeth sometimes and can vary from ground glass, cotton wool, orange peal to cystic RLs. Can be multilocular, expansile, and displace, and resorb teeth, often appears more RO than this lesion though, can be aggressive if it is the craniofacial variant.
TX- surgical
Gingival Cyst of the adult
Chapter 1
Patient: No gender
Age: 40-50
Site: On attached or free facial gingiva, 75% mandibular canine to premolar area
Appearance: Bluish or pinkish nodule, vital tooth

Well-defined, single, RL,
Patient: Slight Males
Age: Average age of 49 but can occur in all ages
Site: Mandible- 3x more common than maxilla- Anterior more common
Appearance: Can be large, uni or multilocular, expansile, perforate bone, tip teeth, corticated with areas of septa and uneven appearance.
Hyperparathyroidism
Ill-defined unless Brown tumor that looks like CGCG
Patient: Females
Age: Middle age
Site: More in the anterior maxilla 60% but has been seen in posterior mandible 40%
Appearance: Loss of density/ground glass from loss of Ca++ in bone. Can cause bone pain- jaws and fingers most common bones involved
TX: Underlying disease
Juvenile Ossifying Fibroma
Well-defined, mixed, single
Patient: No gender preference
Age: 11-20
Site: Maxilla most common but occurs in mandible too
Appearance: Well-defined, mixed, RL to RO, can be expansile, aggressive and fast growing, can displace and resorb teeth.
