Fibroma cemento ossificante: aspectos epidemiológicos, clínicos, imagenológicos e tratamentos empregados no serviço de CTBMF da UFU

Abstract

Cemento Ossifying Fibroma (FCO) is a rare tumor, benign in origin and classified as a fibro-osseous lesion located in the craniofacial region. This lesion is usually asymptomatic. In most cases, it becomes noticeable when the tumor grows in volume, causing some deformity at the site, and clinical manifestations such as occlusal and aesthetic problems are frequent. The diagnosis of FCO is usually made by a combination of clinical, radiographic and histological evaluation. The aim of this study was to retrospectively describe and analyze the frequency of cases diagnosed with the disease at the Oral Pathology Laboratory of the Federal University of Uberlândia, identifying information on sex, age, color, symptoms and radiographic features in order to understand its morphological and epidemiological characteristics, as well as information on the treatments used by the Oral and Maxillofacial Surgery and Traumatology department of the Federal University of Uberlândia (CTBMF-UFU). This study was approved by the CEP-UFU under CAAE number: 51088121.1.0000.5145. Data was collected from the medical records of patients previously identified with FCO lesions at the Dental Hospital of the Federal University of Uberlândia (HO-UFU) and the Clinical Hospital of the Federal University of Uberlândia (HC-UFU). Benign fibro-osseous lesions accounted for 305 cases in our sample of biopsy records, of which 27 were diagnosed as cemento-ossifying fibroma (FCO) and 19 medical records were analyzed. The majority of FCO affected white women between the third and fourth decades of life. The mandible was most affected by FCO, most patients reported being asymptomatic and volumetric enlargement was the most common complaint. Regarding the radiographic aspect, a mixed presentation was the most common and tooth displacement was the most common recurrence. Resection treatment was the most common approach, performed in 50% of cases, with paresthesia in the inferior alveolar nerve being the main post-operative complication. Thus, we can conclude that the clinical-pathological findings and treatments employed by the CTBMF-UFU service for patients with Cemento Ossifying Fibroma were similar to those described in the majority of published studies on the lesion.
