Resumo de Recurso
Cysts
Epithelial = True Cysts
Odontogenic
Inflammatory
Radicular cyst
Non-vital tooth
Pulp necrosis -> Proliferation of Cells of Malassez -> Fluid accumulation
Most common = U2s
Most common cyst
Buccal expansion
If tooth removed --> can recur as Residual cyst
Paradental cyst
History of pericoronitis
Similar to Radicular cyst
Lower 8s - buccal/distal
Developmental
Dentigerous cyst
Unerupted tooth
Derivation = tooth follicle
Eruption cyst
Extra-alveolar dentigerous cyst
Often blood filled
Most common = 6s
Childen
Most common = L8s & U3s
Buccal expansion
Odontogenic Keratocyst
Vital teeth
No buccal expansion
Gorlin-Goltz syndrome
BCCs
Posterior mandible
High recurrence rate
Derivation = Dental lamina/Cell rests of Cerres/Enamel organ
Most aggressive cyst
Treatment = Enucleation + Carnoy's solution (modified)
Lateral periodontal cyst
Lateral to tooth
Rare
3s, 4s, 5s
Small size
Vital teeth
Unknown deriavation
Gingival cyst
Rare in adults
Interdental papillae
Common in neonates
Spontaneously resolve
Derivation = Cell rests of Cerres
Non-odontogenic
Nasal Palatine duct cyst
Midline palate
Swelling +/- salty discharge, pain
Vital teeth
Heart-shaped
Derivation = remnants of naso-palatine duct
Naso-labial cyst
Swelling in nasolabial fold +/- pain, nasal obstruction
Derivation = embryonic nasolacrimal rod/duct
Primary Bone Cysts
Solitary bone cyst
Children
Premolar region, mandible
Fibrous tissue only
Gas or fluid filled
Aneurysmal bone cyst
Highly vascularised fibrous tissue, blood, osteoid, osteoblasts
Children, young adults
Angle of mandible
Multi-locular
Rare
Features
Well-defined, corticaled outline
Shape
Uni-locular
Lateral periodontal cyst
Radicular cyst
Paradental cyst
Dentigerous cyst
Multi-locular
Aneurysmal bone cyst
Either
Odontogenic keratocyst
Uniformly radiolucent

Adults
Radicular cyst
Dentigerous cyst
Lateral periodontal cyst
Nasal palatine duct cyst
Children
Primary Bone cysts
Eruption cyst
Gingival cyst
Site
Posterior mandible
Lower 8s
Dentigerous cyst (unerupted)
Paradental cyst
Odontogenic keratocyst
Aneurysmal bone cyst
Premolar mandible
Solitary bone cyst
Upper anterior
Radicular cyst (U2s)
Nasal palatine duct cyst (midline)
Treatment
Enucleation
Most common/definitive
Marsupialisation
Reduce cyst size
May allow tooth to erupt (Dentigerous cyst)
Shorter/avoid GA
Decompression
Reduce cyst size
