How common is cementoblastoma?
The cementoblastoma has been classified as a benign tumor of odontogenic origin derived from ectomesenchyme. It is an uncommon tumor comprising less than 0.69%–8% of all odontogenic tumors.
What are the characteristics of cementoblastoma?
Histologically, cementoblastoma is characterized by masses of hypocellular cementum embedded in a fibrovascular stroma [1, 2, 5–7]. There is typically prominent cementoblastic rimming [2, 3, 5–7].
What are the signs and symptoms of cementoblastoma?
Cementoblastoma is most commonly observed in males at a mean age of 21 years (8). The majority of patients are usually entirely asymptomatic, and diagnosis is often made according to X-ray observations. Certain patients experience swelling, pain, tooth mobility, paresthesia or cortical expansion of the mandible.
How is cementoblastoma diagnosed?
Diagnosis. A cementoblastoma in a radiograph appears as a well-defined, markedly radiopaque mass, with a radiolucent peripheral line, which overlies and obliterates the tooth root. It is described as having a rounded or sunburst appearance.
Do you have to remove cementoblastoma?
In spite of the presence of pulp vitality, in cases of cementoblastoma, the surgical act of removing the lesion and part of the tooth root must be performed after endodontic treatment[6].
What causes cementoblastoma?
Cementoblastoma arises from cementoblasts, which are normally involved in the formation of cementum. Cementoblastoma is commonly located in the mandibular molar area. There are no genetic mutations associated with the development of cementoblastoma.
What is the treatment for cementoblastoma?
The most common therapy for cementoblastoma is complete enucleation associated with extraction of the involved tooth (3,4,9). Tooth extraction is recommended to simplify the differential diagnosis between cementoblastoma and other lesions not involving the dental root during histological examination (26).
