The author observed radiographs which were diagnosed as odontogenic fibroma,
odontogenic myxoma, central cementifying fibroma in the department of Oral Radiology
and Oral Pathology, Seoul National University Hospital, from 1975 to 1985.
The following conclusions were made.
1. Odontogenic fibroma
The age ranged from 32 to 72 years, and two were females and one was male. All
the three cases occurred in the posterior region of the maxilla. Two cases were
unilocular pattern, and one was multilocular pattern.
2. Odontogenic myxoma
The age ranged from 40 to 55 years, and four were females and two were males. Of
2 cases occurred in the mandible, both cases occurred in the molar area involving the
mandibular body and angle.
Of 4 maxillary lesions, one occurred in the anterior area, two occurred in the premolar
area, and one occurred in the molar area. All the cases showed multilocular
radiolucencies, and most of them (5 cases) had ill-defined border.
3. Cementifying fibroma
The cementifying fibroma occurred more common in young and middle aged adults
with greatest incidence in 5th decade. It is more common in females with the ratio of
about 2 : 1.
Of 19 cases, 15 cases occurred in the mandible, and 4 cases occurred in the maxilla.
Of the mandibular lesions, 14 cases involved premolars and/or molars, and all the 4
cases of maxillary lesions occurred in the premolars and/or molar area.
Radiographically, two were radiolucent type of early stage, twelve were mixed type of
intermediate stage, and five were radiopaque type of mature stage.
