Ameloblastoma is most common in what demographic?
40 year old black males
 
Where is the most common location for ameloblastoma?
80% in molar ramus region If in maxilla then it is most likely in the 3rd molar reegion, but can also be found in maxillary sinus or nasal floor.  
The early ameloblastoma lesion has a ______ appearance while the adavanced lesion looks like ________________.
1) unilocular radiolucency 2) larger with internal compartments seperated by coarse curved septa
What is the treatment for ameloblastoma?
First a CT and MRI to determine location.  If it is a small lesion then it is removed using an intraoral approach. If extensive then an en bloc resection of jaw is indicated.
A calcifying Epithelial Odontogenic Tumor is also know as a ____________ tumor.
Pindborg
Calcifying Epithelial Odontogenic Tumor is common among what demographic?
40 year old men   (Wide age range. Occurs earlier in men and later in women)
What is the only symptom associated with Calcifying Epithelial Odontogenic Tumors?
jaw expansion
52% of CEOT's are associated with __________.
an unerupted or impacted tooth.
What is the treatment for a CEOT?
The same as for ameloblastoma   Remove with intraoral approach if small If extensive then remove using en bloc resection of jaw
What is the most common lcation for a CEOT?   Calcifying epithelial odontogenic tumor
In the premolar to molar area of the mandible   2x more likely to occur in mandible than maxilla
An odontoma is what type of lesion?
benign odontogenic mixed lesion
What is the most common odontogenic tumor?
Odontoma
What does a complex odontoma look like in comparsion to a compound odontoma?  
Complex odontoma - nondescript mass of dental tissue (60% occur in females) Compound odontoma - multiple well formed teeth (2x more common than complex odontoma)
What is the most common location of compound odontomas and complex odontomas?
Compound odontoma - 62% in anterior maxilla with unerupted canine Complex odontoma - 70% found in the the mandibular 1st and 2nd molar area
Odontomas generally occur in what decade of life?
2nd decade
What is the progression of an odontoma?
Form, mature, and stop growing with the developing tooth.
Ameloblastic Fibroodontomas are most commonly located where?
Posterior mandible
Ameloblastic fibroodontomas are commonly associated with ________________.
an impacted tooth
What is the treatment for an ameloblastic fibroodontoma?
Conservative enucleation
What is the treatment for an odontoma?
Simple excision
Ameloblastic Fibromas are most commonly located where?
Premolar to molar area of the mandible   (Sometimes in in ramus or anterior of mandible)
Ameloblastic fibromas generally occur in what age group?
5-20 year olds (during tooth formation)
What is the apperance of ameloblastic fibroma in comparison to dentigerous cysts?
Ameloblastic fibroma appear as outgrowths from dental follicle rather than encompassing entire crown
What is the treatment for an ameloblastic fibroma?
Enucleation and mechanical curretage of the surrounding bone
What is the major radiographic difference between ameloblastic fibroontomas and ameloblastic fibromas?
Ameloblastic fibroodontomas contain small segments of enamel and dentin (ie calcifications)
Adenomatoid Odontogenic Tumors are most commonly located where?
75% are in the incisor to premolar region of the maxilla (90% are near the incisors)  
Adenomatoid odontogenic tumors most likely occur in what demographic?
20 year old females (70% occur in the second decade of life)
What is the radiographic difference between a adenomatoid odontogenic tumor and a dentigerous cyst?
Adenomatoid odontogenic tumors do not attach at the CEJ like dentigerous cysts.
What is the treatment for an adenomatoid odontogenic tumor?
Surgical excision
Odontogenic Myxomas are most common in what demographic?
10-30 year old females
Odontogenic myxomas are most commonly located where?
Mandible: premolar and molar region (rarely found in ramus or condyle) - 3 x more likely to occur in the mandible Maxilla: alveolar process in premolar and molar regions, zygomatic processes
Odontogenic myxomas are usually associated with ________________.
a congenitally missing or unerupted tooth
What is th treatment for odontogenic myxomas?
Resection with generous amountt of surrounding bone to ensure removal of tumor that infiltrates into marrow spaces
What is the most common location of benign cementoblastomas?
MPremolar or first molar region of the mandible
What is the most common demographic for benign cementoblastomas?
10-30 year old males
What is the radiographic appearance of benign cementoblastomas?
A bulbous growth around and attached to apex of tooth root that has a mixed radiolucent-radiopaque appearance. (wheel spoke pattern) Tooth is still vital!!!
Osteomas are common among what age group?
People over the age of 40.
Where is the most common location of osteomas?

With osteomas, ___________ lesions are more common in men and _____________ lesions are more common in women.
1) cortical 2) cancellous
What is the most common location of central hemangiomas?
Body of the mandible (2x nore likely to occur in mandible than maxilla)
What is a major distinguishing radiographic finding associated with central hemaniomas?
Canal widening
Osteoblastoma are most common among what demographic?
10-30 year old males
What are the most common location of osteoblastomas?
Toothbearing regions and TMJ (w/in condyle of temporal bone)
