- - - - Dentigerous cyst: cyst surrounding the crown of an unerupted tooth
      - Eruption cyst: dentigerous cyst within the soft tissue
      - gingival cyst of infants
      - lateral periodontal cyst: inflammatory cyst in the lateral periodontal space of a vital tooth
        
        Botyroid cyst: forms from a group of cells to look like a group of cysts
      - gingival cyst of adults
      - glandular odontogenic cyst: large, slow growing, mostly in anterior mandible, crossing the midline.
      - odontogenic keratocyst: large and sometimes multilocular, commonly around the ramus and body of the mandible and keratinised (para), sometimes producing satellite cells
        
        Orthokeratinised odontogenic cyst: similar to OKC but orthokeratinised, rare recurrence compared to OKC
    - - radicular cyst: most common, in relation to pulp infection that spreads to apical areas (result of periapical granuloma), becomes a residual cyst once the tooth is extracted.
      - Paradental cyst: cyst due to pericoronitis (next to the tooth)
      - buccal bifurcation cyst: deep period pocketing, unilocular occurrence beside vital teeth
  - - - Ameloblastoma: causes bony exansion
      - Adenomatoid Odontogenic tumour: DDX dentigerous cyst, AOT has a radiopaque margin
    - - Ameloblastic fibroma: odontogenic tumour
      - Odontoma: ameloblastic fibroma that forms hard tissue
      - Calcifying Odontogenic cyst: actually a cyst
    - - Odontogenic fibroma: large, multilocular radiolucency
      - Odontogenic myxoma: gelatinous on opening
- - - - Cleidocracial dysplasia + Gardeners Syndrome
      - Anodontia: complete or partial
      - Supernumerary
    - - Macrodontia/microdontia
      - Taurodontism: large, distorted root apex.
      - Ectodermal dysplasia: affects number and shape of teeth
      - concrescence: fusion of cementum of two or more teeth
      - fusion: joining of two or more tooth germs
      - Germination: two crown with one root, partial division of a germ
      - dilaceration: abnormal curve in root or crown
      - dens invaginatus: enamel developing into the middle of the tooth, external communication with pulp
      - dens evagintus: spherical mass of enamel on occlusal surface, may contain pulp tissue
      - Enamel pearl: mass of enamel at bifurcation may contain plural tissue
    - - Amelogenisis imperfecta: hypoplastic or hypomineralised enamel
        
        Enamel hypoplasia: may be due to amelogenesis imperfecta
      - detinogenesis imperfect: improper binding between enamel and dentine.
      - dentinal dysplasia:affects both dentitions roots and pulps, irregular dentine (difficult to distinguish between dentinogenisis imperfecta).
- - - - fibrous epulis: fibrous mass on gingival margin, may be ulcerated
      - fibroepithelial polyp: fibrous epulis occurring anyway other than the gingiva
      - giant cell epulis: blue-purple mass on gingiva
      - Pyogenic granuloma: soft, red swelling on interdental papilla
