ODONTOMA

  1. 1. ODONTOMA PRESENTED BY Dr. Mazhar. I. Khan Sapporo Dental College & Hospital,
  2. 2. INTRODUCTION • Odontomas are the developmental malformation of the dental tissues. • They are hamartomas also commonly known as odontomes. • They have all the basic histological structures of a tooth but in a disoriented fashion or may vary morphologically.
  3. 3. ETIOLOGY AND BEHAVIOUR • Odontomas are hamartomas of odontogenic epithelium and mesenchyme. • They are usually found between the age of 10 and 20 years • They are benign in nature. • Most common sites are anterior maxilla and posterior mandible.
  4. 4. CLASSIFIACTION  In the past, complex type of classification was devised to include developmental anomalies such as dilated,invaginated and geminated Odontomas. They are now simply classified as • compound Odontomas • complex Odontomas
  5. 5. COMPOUND ODONTOMA •Probably produced by localized multiple budding off from the dental lamina and formation of many tooth germs. •Consist of many separate, small tooth like structures. •Gives rise to a painless swelling in the anterior part of the jaws clinically. •Radiographically seen as separated densely calcified tissue. •Histologically,the denticles are embedded in fibrous connective tissue having fibrous capsule.
  6. 6. COMPLEX ODONTOMA • Irregular mass of hard and soft dental tissue showing no resemblance to a tooth. • Clinically hard painless swelling seen in young persons. • Radiographically seen as a radiopaque irregular mass when fully calcified with areas of densely radiopaque enamel. • Histologically, tissues arranged in a disordered arrangement frequently in radial pattern. • Multiple branching of pulp gives a sponge like appearance.
  7. 7. COMPLICATIONS • Obstruction of tooth eruption. • Mass may erupt causing infection and abscess. • Mass may undergo cystic change or resorption.
  8. 8. MANAGEMENT • The mass of tissues are removed by conservative surgery. • They respond to enucleation
