- Derived from rests of dental lamina (rests of Serres)
- Painless, dome-like swellings which are less than 5mm
Lateral Periodontal Cyst
Location between the canine and lateral incisor
Conservative enucleation is treatment
Hard tissue counterpart of gingival cyst of the adult
Bucal Biforcation Cyst
- Rests of Seres
- Apex of teeth tipped lingually
- Occurs in children, avg age of 10
- Treated by enucleation
- No need to extract the tooth
Dentigerous Cyst
Unilocular, radiolucent and impacted
- Cyst that originates by separation of the follicle from around the crown of an unerupted tooth
- Most common developmental cyst
- Treatment is enucleation of the cyst together with the unerupted tooth
- Large examples may be treated by marsupialization
- Usually do not, but can grow to considerable size & expand bone, cause facial asymmetry, etc.
- That’s why they must be removed (that and to rule out other cysts like OKC)
- Calcifying epithelial odontogenic tumor, Ameloblastic fibro-odontoma, Calcifying odontogenic cyst and Adenomtoidodontogenic tumor are differetials
Adenomatoid Odontogenic Tumor
“Snowflake calcifications”
- *Striking tendency to occur in the anterior jaws
- *Mx>Md
- *F:M 2:1
- Occurs in young patients, ages 10-20
- *In 75% of cases, the tumor is a circumscribed, unilocular RL involving the crown of an unerupted tooth*
- Most often a canine tooth
- Tumor has a thick, fibrous capsule that makes enucleation easy
- Dentigerous cyst, Calcifying epithelial odontogenic tumor, Calcifying odontogenic cyst and Ameloblastic fibro odontoma are differentials
Calcifying odontogenic cyst
- Gorlin cyst
- Ghost cells
- 65% are found in the incisor-canine areas; mx=md

- Most patients affected are women in their 60s
White Sponge Nevus
- Genodermatosis
- Autosomal dominant
- Benign condition with no treatment
Compound Odontoma
- Most common odontogenic tumor
- Considered to be developmental anomalies (hamartomas) rather than true neoplasms
- Divided into compound and complex types
- Compound – Composed of multiple, small, toothlike structures
- Complex- Conglomerate mass of enamel and dentin; bears no anatomic resemblance of a tooth
- Ave age – 15
- Completely asymptomatic
Ash Leaf Spots
Found in tuberous sclerosis
- Mental retardation

Desquamitive Gingivitis
Pemphigus, Pemphigoid, Systemic lupus erythematous, Lichen planus, Hypersensitivity
Pemphigus
Tzank cells
Pemphigoid
- Twice as common as pemphigus
- Most significant complication is the ocular involvement (up to 25%) symblepharons
- Scarring can turn the eyelids inward (entropion), which causes the eyelashes to rub against the cornea
- Scarring can close opening of lacrimal glands
- After all this happens, the cornea produces keratin as a protective mechanism
- Autoantibodies are directed against the basement membrane, leading to a subepithelial split (interepithelial)
- Direct immunofluorescence (DIF) shows C3 and IgG along the basement membrane
- Send to Opthamologist!!!
Pemphigus
- “First to show, last to go”
- Autoantibodies are directed against the desmosomes. “Intra”
- A characteristic feature is a positive Nikolsky sign: Bulla can be induced on normal-appearing skin if firm lateral pressure is exerted
- Cells of the epithelium “fall apart” – termed acantholysis
LichenPlanus
- May be due to medications, amalgam, etc. – “lichenoid mucositis”
- Skin lesions are the 4 Ps:
- Purple
- Pruritus
- Polygonal
- Papules
- Degenerating keratinocytes within the epithelium (termed Civatte bodies)
- Wickam Striae
- Lesions can be induced with the following:
- S – Stress
- T – Trauma
- A – Advil (any NSAIDs, acetaminophen is ok)
- Y – Yeast
- Desquamative gingivitus, Pemphagoid, Pemphigus, Systemic lupus erythematous are differentials
- DON’T Treat RETICULAR lichen planus
