Imaging of ameloblastomas: a pictorial review
No full textOBJECTIVES: Ameloblastomas are the most common clinically significant odontogenic tumor constituting 18% of all odontogenic tumors. Ameloblastomas are a rare, benign, slow-growing but locally invasive odontogenic neoplasm involving the mandible and the maxilla.
The aim of the present article was to review and depict the main radiological features of ameloblastomas.
MATERIALS AND METHODS: A review of articles published between January 2000 and October 2020 using Medline and the MeSH term “ameloblastoma” in combination with the following terms “imaging” “radiology”, “panoramic radiograph”, and “computed tomography”, was performed.
RESULTS: The most frequently adopted radiological imaging techniques for the study of ameloblastomas are panoramic radiograph, CBCT and computed tomography.
On radiographs, CBCTs and CTs, ameloblastomas are radiolucent and either unilocular or multilocular.
Panoramic radiography allows for a preliminary assessment of the location, size, shape, margins and extension of the lesions. It allows for a kind of “screening” X-ray examination and remains the first choice in the initial evaluation of tumors of the jaws
CONCLUSIONS: Dental practitioners should be aware of the radiological features of ameloblastomas. CT and CBCT scans play an important role in the diagnosis and treatment planning of such lesions, although panoramic radiograph still represents a valid imaging technique.
CLINICAL SIGNIFICANCE: It may not be easy to differentiate between unilocular ameloblastomas from other odontogenic lesions. Histopathological findings are still necessary to obtain a definitive diagnosis
Oral Injuries Associated With Sodium Hydroxide
No full textAim: The aim of the present article is to present and discuss the diagnosis and management of a patient who accidentally re-ported an oral injury due to sodium hydroxide.Material and Methods: An 83-year-old female patient was referred to the emergency department with lip, oral and tonguelesions. The patient was confused and her recent medical history was unclear: she reported having the intention to drink somesodium hydroxide in order to improve her digestion, but after keeping it in her mouth for some seconds, she described an imme-diate burning sensation in her mouth and said she had spat it out without swallowing. She arrived at the emergency room 3 hafter this episode.Results: Physical examination showed erythema and swelling of the lips, and a diffuse erythema with ulcerations in the oralcavity. Abdominal examination was normal, without pain during palpation. The absence of laryngeal, oesophageal, or gastricinjuries was confirmed by a gastrointestinal endoscopy and a nasofibroscopy. Then, the patient was administered intravenousantibiotics and a proton pump inhibitor, in addition to hydration with saline solution, and she was kept under medical supervi-sion in the emergency room for 12 h before a possible return to home.Conclusions: It is important that the dental practitioners are aware of the clinical features of the oral cavity that could be asso-ciated with the ingestion of caustic substances. An early management with intravenous treatment and a complete and carefuldiagnostic work-up is necessary in such cases
