Introduction

  • Odontoma. Odont means of odontogenic origin. oma means benign tumor
  • Thus by definition alone, Odontoma refers to any tumor of odontogenic origin
  • Reported to be the most common of all odontogenic neoplasms and tumour-like lesions
  • Many authorities believe odontomas to be developmental anomalies (hamartomas), rather than true neoplasms

Definition

Kramer (1974) has defined a cyst as ‘a pathological cavity having fluid, semifluid or gaseous contents and which is not created by the accumulation of pus’. Most cysts, but not all, are lined by epithelium.

Dentigerous Cyst:-

  • Pseudocysts – Cysts of the oral and maxillofacial tissues that are not lined by epithelium
  • Example of Pseudocyst:
    • Mucous extravasation cyst of the salivary glands
    • Aneurysmal bone cyst
    • Solitary bone cyst
