Benign cementoblastoma of the anterior mandible: an unusual case report

Abstract

A benign cementoblastoma, which is another name for a true cementoma, is a rare neoplasm that develops from odontogenic ectomesenchyme. It is characterized by a mineralized mass attached to the apex of the root produced by neoplastic cementoblasts. More than 75% of cases arise in the mandible, with 90% of them manifesting in the molar and premolar regions. This neoplasm occurs most commonly in children and young adults, with males being affected slightly more than females. Radiographically, the tumor is observed as a well-defined radiopaque mass that is fused to a tooth root and is surrounded by a radiolucent rim. The treatment of benign cementoblastoma consists of removal of the lesion and extraction of the affected tooth. This report presents an unusual case of benign cementoblastoma in a 31-year-old female, presenting as a densely mineralized mass seen at the apex of the impacted right mandibular canine tooth on radiographs.

Cementoblastoma in the Maxilla: An Unusual Case Report

“…This is now the oldest reported age occurrence for cementoblastoma in the Western population. Pain, tenderness and swelling are present in most cases of cementoblastoma [2,8,11]; however, some cases can be asymptomatic [1,4,6,7,8]. In the present case, the tooth was vital and asymptomatic, however, unlike most cases described in the literature, no swelling was observed and the lesion was only detected from the radiographic examination.…”

“…The typical clinical presentation of cementoblastoma includes: male or female under 30-years-old, can be painful or asymptomatic, swelling, located in the premolar/molar region, [1,4,6,10,11,12,13], more frequently in the mandible [1,4,6,7,10,12,11,12,13,14,15,16]. Previous studies have reported the occurrence of cementoblastoma in the right maxillary and mandibular canine [6,8], right upper posterior tooth region [1], maxillary central incisor [7], mandibular first molar [14] and maxillary right first molar [4]. In the case described here, a tumor was identified in the left posterior maxilla of a 52-year-old female.…”

“…Two methods have been reported for treatment of cementoblastoma. The more invasive consists of excision and extraction of the associated tooth [1,2,4,5,6,7,8,14]. The least invasive being apical resection and root canal treatment of the affected tooth [1,2,20].…”

“…In the case reported here, the most invasive method was chosen because it presents a lower rate of recurrence [1,2]. The reported recurrence rate ranges from 9-37% [4,6,8,20].…”

“…The majority of cementoblastomas are located in the mandible, most commonly in the molar region [1,2,4,5,6,7]. There is no gender predisposition [2,6,7,8], and the age of occurrence ranges from 8 to 44 years [2], with the highest incidence in the second and third decades of life [2,4,6,7,8,9]. This paper describes an unusal case of a patient who was diagnosed with cementoblastoma based on radiographic, surgical, and histological findings.…”
