Abstract
|
|
|
Odontoma is defined as a benign odontogenic tumor containing enmel, dentin as well as cementum. It has come to mean a growth in which both the epithelial and the mesenchymal cells exhibit complete differentiation.
Most authorities accept the view today that the odontoma represents a hamartomatous malformation rather than a true neoplasm.
The etiology of odontomas is uncertain but hypothesized to involve local trauma, infection inheritance or mutant gene.
The odontomas often cause various disturbances in the eruption and position of the teeth. The steps in removal of an odontoma in close relation to an adjacent impacted normal tooth should comprise 1) removal of odontoma and 2) exposure of the impacted tooth. Orthodontic therapy may be applied. Before treatment, the necessary space fur the impacted tooth should be evaluated. If there is lack of space in the dental arch, orthodontic treatment should be carried out before operation.
