Multiple Cementoblastoma: A Rare Case Report

Abstract

Benign cementoblastoma is a rare ectomesenchymal odontogenic tumor that originates from the root of the tooth and that is characterized by the formation of cementum-like tissue. A 60-year old man was referred to us complaining of pain in his right jaw. The patient underwent TC dental scan of the mandible, which highlighted the presence of three well-circumscribed, round, unilocular neoformations of radiopaque appearance with a radiotransparent edge, one of which was in close contact with the roots of the lower right second molar. Microscopic examination of the greater sample consisted, in its central portion, of dense mineralized acellular trabeculae of basophilic tissue cement-like, devoid of vessels, adhering to the root of the tooth, while peripherally was observed a zone of vascularized osteoid surrounded, occasionally, by a thin rim of cementoblasts mixed with fibrous tissue and inflammatory elements. This lesion was diagnosed as cementoblastoma. The second lesion appeared radiologically and histologically entirely identical to cementoblastoma, but it did not show the intimate association with the root of involved tooth. After a careful review of the literature, the diagnosis of residual cementoblastoma was made. The clinicopathologic features, treatment, and prognosis of this rare tumor are here discussed for the young dental practitioner.

“…Sementoblastoma diş kökünden orijin alır ve radyografide diş kökleri ile yakın ilişkili ince radyolüsens hat ile çevrili radyoopak yığınlar olarak görülür. 4,[14][15][16][17][18] Odontoma mezenşimal ve epitelyal dental elementler içeren en yaygın bening odontojenik tümörlerdir. Kompaund odontoma yaygın olarak anterior maksillayı etkileyen ve radyografide diş benzeri uniloküler radyoopak alanlar içeren lezyonlardır.…”

Surgical treatment of cementoblastoma associated with apicoectomy and endodontic therapy: Case report

“…This treatment has been applied in other studies with good clinical results and absence[ 13 , 14 ] of recurrence or rate of recurrence similar to that of treatment by tooth extraction[ 1 ]. However, removal of the affected tooth is still the option most indicated in case reports and previous studies[ 2 , 7 , 15 ].…”

“…Due to the high rates of recurrence (approximately 31.7%) associated with incomplete removal of the lesion[ 1 ], the treatment of cementoblastoma most indicated in the literature, is removal of the tooth together with the tumor[ 6 , 7 ]. However, endodontic treatment of the affected tooth associated with apicoectomy during removal of the lesion is cited as an alternative[ 1 ], allowing the tooth to be maintained in function[ 1 ].…”

A Rare Odontogenic Tumor Known as Cementoblastoma; A Case Report

“…(3) Cementoblastoma is rare in the oral cavity and accounts for less than 1% of all odontogenic tumors and is currently classified by the 2005 WHO as an ectomesenchymal odontogenic tumor with or without odontogenic epithelium that originates from dental roots and is characterized by cementum formation. (3,4,7,8) Cementoblastoma or true Cementoma is a slow growing tumor mostly involving the permanent dentition. It is especially uncommon in children.…”

“…(3,4,5,8) The tumor has been also associated with multiple teeth or impacted molars. (5,7) No significant sex predilection has been reported, however some authors have reported contradictory findings. (4) The average tumor size is 2.1 cm.…”
