hx of ceot

polyhedral cells | calcified amyloids in concentric pttern

concentric pattern in ceot

Liesegang rings

tx of ceot

same with ameloblastoma

pindborg tumor

ceot

found in maxilla anterior region impacted maxi canine

aot

hx of aot

rosette and ductlike structures

tumor that resemble glands

AOT

mesenchymal

odontogenic myxoma cementoblastoma periapical cemento-osseoud dysplasia

rx radiopaque mesenchymal

cementoblastoma

replacing root outline (end part of root not seen anymore bc of tumor)

cementoblast

surrounded by radiolucent ring and cont to PDL

cementoblast

tx of cementoblast

surgical excision with removal of the assc tooth

ddx of cementoblastoma

condensing osteitis | osteoblastoma

lesion fused or connected to the root

cementoblastoma

cementoblastoma aka

true cementoma

mesenchymal odontogenic tumor with honeycomb pattern

odontogenic myxoma

most likely to recur after surgery

amelobalstoma

myxoma resembles what tissue

pulp

tx of odontogenic myxoma

excision

fibroblast collagen capillaries as hx

odont myxoma

soap bubble or honeycomb rx

cama

memsenchymal and always radiolucent

odont myx

has loose gelatinous consistency

odont myx

what are 3 things that looks the same

follicular ct pulp myxoma

most common mesenchymal odontogenic tumor

odont myxoma

dental papilla turns to

odontoblast

odontoblast turns to

dentin and pulp

enamel organ becomes

enamel

dental sac produces

cementoblast fibroblast osteoblast

chronic focal sclerosing osteomyelitis

condesing osteitis

has no radiolucent ring and preserve root structure on rx

condensing osteitis

infection prior before it can form

conden ostei

has radiolucent ring but no continui to PDL

osteoblastoma

mixlucent

osteoblastoma

these are lesion with abnormality with regards to fibrous tissue and osseous tissue

FOL

4 FOL

ossifying fibroma fibrous dysplasia cemento osseous dysplasia cherubism

3 types of cemento osseous dysplasia

periapical cod focal cod florid cod

cod that has the entire maxila or jaw or 2 or more quadrants affected

florid cod

seen in edentulous areas or after exo since it is isolated

focal cod

most common FOL

COD

located at apex of mandibular teeth and teeth remains vital

PCOD

False cementoma

cemento or PCOD

Black women or African american women are prone to it

PCOD

progresses from radioluscent to radiopaque bc the bones try to fight

pcod

hx has cementum bone and fibrous tse

PCOD

Tx of PCOD

none

a mixed tumor

odontoma

asymptomatic seen on maxilla and retains decidous tooth and impacts permanent tooth

odontoma

classification of odontoma

compound - toothlike structure and on anterior regions | complex - amorphous conglo and posterior region

is odontoma radiopaque? why?

yes bc it mimics tooth

tx of odontoma

excision
