Cementoblastoma, or benign cementoblastoma, is a relatively rare benign neoplasm of the cementum of the teeth. It is derived from ectomesenchyme of odontogenic origin, with the formation of cementum-like tissue around the associated tooth root.[2] Cementoblastomas represent less than 0.69–8% of all odontogenic tumors.[2] The oldest case of cementoblastoma that has been verified dates back to 1888 by J. Metnitz.[3] He described a lesion as a hard rounded mass associated with root resorption, periosteum coverage, rows of bone cells, and pulp chamber involvement. At the time, the lesion was diagnosed as an "odontoma", but later it was found that a diagnosis of cementoblastoma better matched the description.
