dental follicle. The central odontogenic fibroma consists of collagenous
fibrous connective tissue containing varying amounts
of odontogenic epithelium (3). Connective tissue proliferation
can have different localizations and there exist both intraosseous
(central) and gingival (peripheral) lesions designatedas
odontogenic fibroma. While peripheral odontogentic fibroma
clearly represents a periodontal lesion, the central odontogenic
fibroma usually resembles an endodontic lesion and it is reported
in endodontic or oral pathology journals (4, 5).
Some authors in an international classification of oral tumors
have reported that some COF could contain varying amounts
of hard tissue resemblingdysplastic cementum or bone (6).
Clinically, the central odontogenic fibroma could appear as
an asymptomatic expansion of the buccal or lingual cortical
plate, occurring in the mandible and in the maxilla with equal
frequency. In the maxilla the lesion appears frequently to involve
the anterior region, whereas in the mandible the lesion tends to
be located in the posterior area, involving thepremolar and molar
areas. The radiological examinations of this lesion appear as an
area of radiolucency or as an area with a mixed radiodensity,
most of the time the lesions have well-defined boarders (7). The
central odontogenic fibroma has been described as a unilocular
(8, 9) or a multi-locular radiolucent lesion (10), root resorption
and displacement have also been reported in cases ofmore
severe lesions.
The aim of this case report was to analyze clinical and histological
features of a central odontogenic fibroma, occurring in the
area of the maxillary canine and followed up for 6 years after
surgical excision.

ABSTRACT
Objective: The aim of this case report was to analyze clinical and
histological features of a central odontogenic fibroma followed
up for 6 years after surgical excision.
Methods: A 26-year old Caucasian female was referred, reporting
a painless gingival swelling in the buccal area of the
maxillary right canine. There were no other symptoms and norecent history of pain. Her medical history was non-contributory.
Radiographic evaluation showed the presence of a radiolucent
area with well-defined margins. The lesion was surgically removed
and histologically analysed.
Results: Histologic analysis showed a cellular fibroblastic tissue
characterized by interwoven bundles of collagen densely
packed and absence of odontogenic epithelium.The surgical
site was monitored for 6 years after surgery with no signs of
recurrence.
Conclusion: The central odontogenic fibroma here reported
displayed a prominent quantity of collagen and absence of
odontogenic epithelium. The surgically removed lesion had a
favourable prognosis and no recurrence for the 6 year followup
period.
