T

he odontogenic fibroma is a benign central tumor of the jaws. There are numerous opinions as to its exact nature. Many authors21 6-8,lo, I1 describe the lesion as being rare or uncommon. Bhaskars takes the opposite view, stating that it is the most common odontogenic tumor of the jaws. Although slow growing and usually asymptomatic, it may become disfiguring because of its expansile nature. Occurrence is most common in the second and third decades of life, and the tumor affects both sexes equally. Conservative surgery is the treatment of choice.

Thornal states that, the oclontogenic fitxoma arises from mesenchymal elements of the tooth germ, dental papilla, dental follicle, and periodontal membrane. Shafer, Hine, and Levy7 think that the presence of a few islands of epithelial cells does not prove odontogenic origin. Most authors believe that a lesion is an odontogenic fibroma if it is associated with teeth, is centrally located, and contains fibroblasts. Many investigatorsl-“2 8 note the presence of hard tissue within the lesion. Bhaskarg terms this calcifying odoontogenic fibroma. CASE REPORT A g-year-old Ryukyuan girl was referred to our hospital for treatment of an expansile lesion of the right maxilla involving the anterior teeth. (See Fig. 1.) The lesion was removed by curettement under general anesthesia. The patient’s recovery was uneventful, and after one year there is no evidence of recurrence, Histologic examination of the lesion yielded the final diagnosis of odontogenic fibroma of the maxilla. (See Fig. 2.)

An abbreviated case report of an odontogenic fibroma occurring old girl has been presented, with a brief review of the literature.
