Cementoblastoma previously misdiagnosed as fibrous dysplasia: Report of an uncommon case and discussion of the differential diagnosis

Mandibular cementoblastoma: Case report

“…The occurrence of the lesion involving more than one permanent tooth, as in the case reported here, is rare [3,[12][13][14]. Regardless of the number of teeth involved, the lesion is always associated with the dental root [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

“…Young adults who are under 30 years of age are most commonly affected [1,3,[7][8][9][10][11][12][13][14][15]17], with a slight male prevalence [2,3,9]. According to Brannon et al [2], 79.5% of tumors occur in the mandible, and in most cases, the lesion involves the first permanent molar [1,7,12,14,17]; in the few cases in which the upper jaw is affected, the maxillary sinus can be involved [3,13]. There are also reports of cementoblastoma associated with impacted [8,11,13] and deciduous teeth [3,10].…”

“…Patients may be completely asymptomatic [1,2,8]; however, bone expansion and pain can occur [2,3,[7][8][9][10][11][12][13][14][15]. Trismus [8,10], dental displacement, and increased mo-bility of adjacent teeth [14] may eventually be observed.…”

“…Radiographically, the lesion presents as a well-defined radiopaque mass, surrounded by a radiolucent halo associated with the root of the tooth or teeth [1,3,[7][8][9][10][11][12]14,15,17,18]. Depending on the developmental stage of the lesion, the radiological appearance and clinical interpretation can vary, leading to an erroneous diagnosis of osteoma or osteoblastoma [8,13,14].…”

“…Its prevalence is higher in young male adults who are under 30 years of age [9]. Cementoblastomas are slow growing lesions [8][9][10] and are usually asymptomatic; however pain, and swelling may occur [2,3,[7][8][9][10][11][12][13][14][15].…”
