  • There are various causes of jaw swelling. odontogenic tumors are pretty much common among them..some are benign some are malignant and some behave like tumors but are not true neoplams. I am drshwetauprety and today in a presenting a case on the non neoplastic odontogenic sweeling of jaw know as odontomas

ODONTOMA ODONTOMA Presentation Transcript

  • ODONTOMA PRESENTED BY Dr. Mazhar. I. Khan Sapporo Dental College & Hospital,
  • 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.
  • 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.
  • 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
  • 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.
  • 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.
  • COMPLICATIONS • Obstruction of tooth eruption. • Mass may erupt causing infection and abscess. • Mass may undergo cystic change or resorption.
  • MANAGEMENT • The mass of tissues are removed by conservative surgery. • They respond to enucleation
