[GROUP 1: Signs and symptoms]
- Occurs in people under the age of 25, particularly males
- Involves the permanent mandibular molars or premolars
- Involved tooth usually has a vital pulp
- Attached to the tooth root and may cause resorption
- Usually asymptomatic, but may be associated with diffuse pain and tooth mobility

[GROUP 2: Diagnosis]
- Radiograph appearance: well-defined, markedly radiopaque mass
- Radiolucent peripheral line overlies and obliterates the tooth root
- Rounded or sunburst appearance
- Apparent external resorption of the root where the tumor and root join
- Consider differential diagnosis with severe hypercementosis and chronic focal sclerosing osteomyelitis

[GROUP 3: Treatment]
- Surgical enucleation of the lesion
- Depending on clinical circumstances, may involve removal of the involved tooth
- Incomplete removal may lead to recurrence
- Some surgeons advocate curettage after tooth extraction to decrease recurrence rate

[GROUP 4: Related Concepts]
- Cementum
- Cementogenesis
- Cementoblast

Cementoblastoma (Wikipedia)

Cementoblastoma, or benign cementoblastoma, is a relatively rare benign neoplasm of the cementum of the teeth. It is derived from ectomesenchyme of odontogenic origin. Cementoblastomas represent less than 0.69–8% of all odontogenic tumors.
