Summary
Odontomas, common benign odontogenic tumors, are often discovered due to impacted teeth. This study analyzed their features, finding they most frequently occur in the maxilla and are associated with unerupted incisors and canines.
Area of Science:
- Dentistry
- Oral Pathology
- Oncology
Background:
- Odontomas are the most frequent benign odontogenic tumors.
- They exhibit high differentiation and favorable biological behavior.
- Histological types include ameloblastic, complex, and compound odontomas.
Purpose of the Study:
- To analyze clinical and radiographic features of odontomas.
- To determine the frequency of odontomas.
- To investigate the relationship between odontomas and tooth impaction.
Main Methods:
- Retrospective study of 26 histologically verified odontoma cases.
- Correlation of histological type with patient age, sex, lesion location, radiographic appearance, size, and impacted teeth.
- Clinical and radiographic feature analysis.
Main Results:
- Odontomas diagnosed primarily in the first two decades; compound odontomas can occur later.
- Most common location is the anterior maxilla.
- Complex odontomas present as mixed radiolucent-radiopaque lesions; compound odontomas appear as radiopacities or atypical teeth.
- Odontomas are typically located superior to the crown of impacted teeth, frequently maxillary incisors and canines.
Conclusions:
- Odontomas are common benign tumors with distinct clinical and radiographic presentations.
- Their association with impacted teeth, particularly in the anterior maxilla, is significant.
- Understanding these features aids in diagnosis and management of odontomas and associated dental anomalies.
