Because complete dislocation of a tooth can cause a frontal sinus abscess, an airway complication, a respiratory tract obstruction, and a complicated lung abscess or sinusitis, anytime a tooth is not accounted for after a dentoalveolar trauma, the possibility that it has been fully intruded should be considered. Computed tomographic scan should be a routine diagnostic study in all cases with associated missing anatomical structures in the oral and maxillofacial region. The need to involve the dental professional in the initial assessment of dental trauma in emergency rooms in hospitals is important in order to identify how many teeth might be missing after dental trauma and to correctly reposition the avulsed teeth when possible.
The aim was to report on a case of ossifying fibroma, consisting of a benign fibro-osseous lesion characterized by slow growth and proliferation of fibrous cellular tissue, bone, cement or a combination.A 29-year-old male patient was attended at a hospital, after he had suffered a car accident. During the clinical examination, increased volume in the region of the right side of the mandible was observed, and a fracture in the middle third of the face was suspected. The tomographic examination showed an image suggestive of fracturing of the left-side zygomatic complex, without displacement, and with a well-delimited radiopaque image of the mandible. The patient was sent to a hospital where panoramic radiography, posteroanterior radiography of the face and teleradiography were performed in order to better document the case. An incisional biopsy was performed. Histopathological examination showed the presence of a benign bone lesion suggestive of ossifying fibroma. Surgery was performed in order to completely remove the lesion, with fixation using a reconstruction plate. A new anatomopathological examination confirmed the diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
