ILLNESSES OF JAWS


Classification

  • according etiology, clinical and morphological displays:

  • -- inflammatory nature diseases;

  • - jaws bones cysts;

  • -tumoroid disease

  • - tumor.



INFLAMMATORY DISEASES

  • ostitis;

  • periostitis;

  • osteomyelitis.



Expansion of ostitis

  • by a contact way

  • along of vascular-nervous fascicle



PERIOSTITIS

  • Acute:

    • serosal
    • festering
  • Chronic (fibrotic)



Оsteomyelitis



CYSTS OF JAWS BONES

  • Оdontogenic

      • Disontogenic
        • prymordial
        • follicle
      • Inflammatory character (radicularis) .
  • Unodontogenic



Radicular or preroot cyst



Radicular cyst with suppuration



TUMULAR DISEASES

  • Fibrotic dysphasia

  • Cherubizm

  • Eozinifilic granulomas



Fibrotic dysphasia of bonejaws



TUMOURS

  • According to histogenesis:

    • Unodontogenic:
      • Benign
      • Malignant
    • Odontogenic.


Osteoblastoclastomae



Malignant unodontogenic

  • Osteosarcoma;

  • Hondrosarcoma;

  • Lymphadenoma.



  • Odontogenic tumours develop from tissues of tooth elements:

    • From enamel organ (ectodermic origin)
    • From tooth nipple (mesenchima origin)


Odontogenic tumours



Histogenesis of odontogenic tumors

  • Tumors which develop from odontogenic epithelium;

  • Tumors which develop from odontogenic mesenchyma;

  • Odontogenic tumors of mixed histogenesis.



Tumours from odontogenic epithelium

  • Ameloblastomas

  • Adenomatic tumors

  • Odontogenic carcinomas



Ameloblastomas



Ameloblastomas

  • Clinic-anatomic forms :

  • Cystophorous

  • Solid .



Ameloblastomas

  • Histological forms :

  • Follicular

  • Plexiform (like net)

  • Akantomatic

  • Basal-cellular

  • Granular-cellular



Ameloblastoma (follicle form)



Ameloblastoma (follicle form)



Odontogenic carcinomas

  • Malignant ameloblastoma

  • Primary intrabone carcinomas



Tumours which are related histologically to the odontogenic mesenchyma:

  • Benign:

  • dentinoma;

  • mixoma;

  • cementoma.



Types of cementomas

  • Benign cementoblastoma

  • Cementitious fibroma

  • Giant cementoma



Odontogenic tumors of mixed genesis

  • Benign

  • Ameloblastic fibroma;

  • Odontogenic fibroma;

  • Odontoameloblastoma;

  • Ameloblastic fibroodontoma



Ameloblastic fibroma



Ameloblastic fibroodontoma



Malignant odontogenic tumors of mixed genesis (odontogenic sarcomas)

  • Ameloblastic fibrosarcoma

  • Ameloblastic odontosrcoma



Forms of odontomas :

  • Compound odontoma

  • “Composited" odontoma.



  • The End!!!
