Abstract
The clinicopathologic features of 44 cases of cementoblastoma were analyzed and compared
with those of 74 cases from the literature with special emphasis on the clinical behavior,
treatment, and recurrence rate of these relatively rare benign odontogenic neoplasms.
The cases in the current series were accessioned at the Armed Forces Institute of
Pathology, Washington, DC. Patient ages at diagnosis ranged from 8 years to 44 years,
with a mean age of 20.7 years. The tumors affected 30 males and 14 females. The mandible
was the site of occurrence in 31 cases (70.4%), with the mandibular first molar the
most common tooth involved. Radiographically, more than 90% of the tumors presented
as well-defined radiopaque or mixed-density masses confluent with the tooth root(s)
and surrounded by a radiolucent rim. Two lesions were radiolucent. Microscopically,
cementoblastomas share similar features with osteoblastomas but are unique because
of their physical attachment to the tooth root(s). Follow-up was obtained in 35 of
44 cases, with a mean follow-up interval of 5.5 years. Recurrence was documented in
13 cases (37.1%), in contrast to the literature, where only 2 of 34 cases (5.9%) with
adequate follow-up recurred. Jaw expansion and perforation of the cortex were noted
in a higher percentage of recurrent than nonrecurrent tumors. Because recurrence and
continued growth are possible if lesional tissue remains after initial surgery, appropriate
treatment should consist of removal of the lesion along with the affected tooth or
teeth, followed by thorough curettage or peripheral ostectomy. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2002;93:311-20)
