epithelial proliferation

In Periapical (Radicular) Cyst, the Cyst formation occurs as a result of ____ which helps to separate the inflammatory stimulus (necrotic pulp) from surrounding bone.

Proliferation of rests of dental lamina; pathologically linked to the gingival cyst of the adult (remnants in soft tissue between the oral epithelium and periosteum).

Treatment for lateral periodontal cyts

fragments of the dental lamina that remain within the alveolar

ridge mucosa after tooth formation proliferate to form these small,

keratinized cysts

not apparent on radiograph

Appearance of gingival cyts of newborn in radiograph

none

they fuse with the overlying oral epithelium

discharge their contents and resolve spontaneously

Treatment for gingival cyst of newborn

proliferation of enamel organ remnant or REE

CA of dentigerous cyts

follicular cyts

other name for dentigerous cyts

second most common type of odontogenic cyts

most common developmental cyts of jaw

The dentigerous cyts is

Dentigerous cyts

It is attached to the tooth cervix at the cementoenamel junction, and it

encloses the crown of the unerupted tooth.

third molars and maxillary canines

Area affected by dentigerous cyts

well-defined, unilocular

radiolucency with corticated margins in association with the crown of an

unerupted tooth

Appearance of dentigerous cyts in radiographic

removal of the associated tooth

enucleation of pericoronal soft tissue

component

treatment for dentigerous cyts

Fluid accumulation within the follicular space of an erupting tooth.

ca of Eruption Cyst

blood may appear within the tissue space, forming an eruption hematoma

apperance of Eruption Cyst due to trauma

none; tooth erupts through the lesion

treatment for eruption cyts

shares some histologic features with a mucus-producing salivary gland

tumor (low-grade mucoepidermoid carcinoma)

CA of Glandular Odontogenic Cyst

sialo-dontogenic cyts

other name for glandular odontogenic cyts

mandibular lesions

Glandular odontogenic cyts is associated by

Radiographic margins are well defined and sclerotic and scalloped.

appearance of GOC in radiograph

Surgical management

Treatment for GOC

Remnants of dental lamina in the maxilla and mandible

CA of Odontogenic Keratocyst

Kertocyts Odontogenic Keratocyst

other name for Odontogenic Keratocyst

jaw expansion

What is uncommon to glandular oodntogenic cyts

Nevoid Basal Cell Carcinoma Syndrome(NBCCS)

The OKC is Aggressive clinical behavior, high recurrence rate, associated with

posterior portion of the body and ramus

Area of mandible affeted by OKC

third molar area

Area of maxilla affected by OKC

- surgical excision with peripheral osseous curettage or ostectomy

-surgical decompression and decompression and marsupialization to permit cyst shrinkage, enucleation

Treatment for OKC

derived from odontogenic epithelial remnants within the gingiva

or within the mandible and maxilla

CA OF Calcifying Odontogenic Cyst

Calcifying Cystic Odontogenic Tumor

other name for Calcifying Odontogenic Cyst

dual cystic and benign neoplastic nature

The COC is a

ODONTOGENIC GHOST CELL TUMOR

The -more aggressive clinical behavior of COC

unilocular or multilocular radiolucencies with discrete,

well-demarcated margins.

Apperance of COC

salt-and-pepper type of pattern with an equal and diffuse distribution

In COC the radiolucency may be scattered, irregularly sized calcifications. Such opacities may produce a

more aggressive than simple curettage

Treatment for COC

epithelial entrapment within a line of embryologic closure within

subsequent cystic change

CA of Globulomaxillary Cyst/Lesion

inverted pear-shaped radiolucency-well-defined

radiolucency often producing divergence of the maxillary lateral

incisor and canine teeth

Apperance of Globulomaxillary Cyst/Lesion in radiographic

between the globular and

maxillary processes

The glubolomaxillary cyts is considered as fissural cyts if it is located in

biopsy

Treatement fro globulomaxillary cyts for definitive diagnosis

definitive microscopic diagnosis.

The treatment and prognosis of globulomaxillary cyts is determine by

unclear; represents cystic change in the solid-cord remnants of

cells that form the nasolacrimal duct

CA of Nasal Labial Cyst

Soft tissue cysts of the upper lip

Affected area for nasolabial cyts

soft tissue swelling that may present in the soft

tissue over the canine region or the mucobuccal fold

Chief clincial sign of nasolabial cyts

curettage

Treatment for nasolabial cyts

fissural cysts similar to globulomaxillary cyst

The Median Mandibular Cyst is cosnidered as

theory of epithelial entrapment in the midline of the mandible

during fusion of each half of the mandibular arch

CA of Median Mandibular Cyst

develops from the proliferation of epithelial remnants of paired

embryonic nasopalatine ducts within the incisive canal.

CA of Nasopalatine Duct (Incisive) Canal Cyst

Nasopalatine Duct (Incisive) Canal Cyst

A non-odontogenic cyst that occurs in the midline of the anterior maxilla, often associated with the nasopalatine duct.

nasopalatine canal or within the palatal soft tissues at

the point of opening of the canal

Location of Nasopalatine Duct (Incisive) Canal Cyst

Appearnce of NDCC in radiograph

The NDCC will poduce what

external root resorption

The NDCC may induce

heart shape

In NDCC the anterior nasal spine often is centrally superimposed on the lucent defect,

producing a
