Developmental Tooth Anomalies
Oral Pathology

Gemination

  • Attempted division of a single tooth germ before calcification.

  • Results in two crowns (complete/incomplete) with one root and canal.

  • Tooth count remains normal.

  • Difficult to differentiate from fusion with a supernumerary tooth.

 Twinning

  • Complete division of a single tooth germ.

  • Results in one normal + one supernumerary tooth.

  • Tooth count is more than normal.

Fusion

  • Union of two separate tooth germs.

  • If before calcification → single large tooth.

  • If after calcification → roots fused, crowns may be separate.

  • More common in deciduous teeth.

Concrescence

  • Union by cementum only.

  • Occurs after root formation.

  • Common in maxillary molars.

Chemotherapy & Radiation Effects
Oral Pathology

  • Chemotherapy Acute Changes: The two common acute changes are hemorrhage and mucositis.

  • Radiosensitivity of Glands: Serous type of glands exhibit more radiosensitivity compared to mucous and mixed glands.

Infantile Osteomyelitis

Oral Pathology

Infantile Osteomyelitis

  • Osteomyelitis Maxillaries Neonatarum, Maxillitis of infancy
  • Osteomyelitis in the jaws of new born infants occurs almost exclusively in maxilla.

Etiology

  • Trauma – through break in mucosa cause during delivery.
  • Infection of maxillary sinus
  • Paunz & Ramon et al  believe that disease caused through infection from the nose.
  • Hematogenous spread through streptococci & pneumococci

Clinical features

  • Fever, anorexia & intestinal disturbances.
  • swelling or redness below the inner canthus of the eye in lacrimal region.
  • Followed by marked edema of the eyelids on the affected side.
  • Next, alveolus & palate in region of first deciduous molar become swollen.
  • Pus discharge from affected sites

D/D for Infantile Osteomyelitis

  • Dacrocystitis neonatarum
  • Orbital cellulitis
  • Ophthalmia neonatarum
  • Infantile cortical hyperostosis

TREATMENT

  • Intravenous antibiotics, preferably penicillin.
  • Culture & sensitivity testing
  • Incision & drainage of fluctuant areas
  • Sequestrectomy
  • Supportive therapy
