Reconstruction of urban sites from photos
2019
Abstract. This paper reports the results of an experiment that aims at the virtual reconstruction of a urban site that has been partially reshaped during the 20th century; the reconstruction process is based on period photos. The chosen case study is the eldest harbour of Palermo, named ‘Cala’; the site was bombed during World War II and new buildings took the place of the ruined ones. Two period photos, taken from an aircraft, document the buildings that were destroyed by bombs. The 3D restitution process used the ‘inverse’ projection from period photos (2D) to the virtual space (3D) ; the first step was therefore addressed to the calculation of the inner parameters (focal length, principa…
Alterations of panoramic radiomorphometric indices in children and adolescents with beta-thalassemia major: A fractal analysis study
2021
Background Beta-thalassemia major is an inherited disorder that can cause bone deformity and loss of bone mineral density. The objective of this study is to evaluate the cortical and trabecular mandibular bone morphology of children and adolescents who have beta-thalassemia major (ß-TM) using a fractal dimension (FD) analysis and different panoramic radiomorphometric indices with digital panoramic radiographic images (DPRIs). Material and Methods The study included 80 patients (with 40 patients each of ß-TM and control). The mandibular cortical width (MCW), panoramic mandibular index (PMI), mandibular cortical index (MCI), and simple visual estimation (SVE) were evaluated, and an FD analysi…
Cone beam computed tomography diagnostic imaging of intra-osseous mucoepidermoid carcinoma in the mandible
2017
Intra-osseous mucoepidermoid carcinoma in the mandible is a rarely reported entity, comprising only 2-3% of all mucoepidermoid carcinomas. Unilocular and/or multilocular radiolucency is characteristic of mucoepidermoid carcinoma, but has a radiographic appearance similar to that of odontogenic benign and malignant tumors and thus cannot be accurately diagnosed on plain films. This article describes a case of a 36-year-old man with intra-osseous mucoepidermoid carcinoma in the left mandible. For a detailed analysis, both panoramic radiograph and cone beam computed tomograph were taken. Important clinico-pathological and imaging features, differential diagnosis and review of the literature ar…
Impact of cone-beam computed tomography for the identification and management of an oral portal of entry in patients with infective endocarditis. A D…
2021
Background Infective endocarditis (IE) is a rare and life-threatening disease. Cutaneous portal of entry (POE) is predominant for IE, but an oral POE is the second most frequent source. Thus looking for and treating an oral POE in IE patients is of critical importance in order to reduce the risk of IE relapse or recurrence. The objectives of this study were: 1) To reach a consensus on decision-making following the detection of an oral POE on cone-beam computed tomography (CBCT) while they were not identified using the current recommended approach in IE patients (oral examination and orthopantomogram: OPT). 2) To determine whether this consensus differs when regarding the microbiology of IE.…
Traumatic neuroma of the mandible: a case report with spontaneous remission
2014
Traumatic neuroma is a well-known disorder involving peripheral nerves, which occurs following trauma or surgery. The lesion develops most commonly in the soft tissues of the mental foramen area, lower lip and tongue. Intra-osseous lesions arising in jawbones are very uncommon. In this paper, we report a new case of an intra-osseous traumatic neuroma, discovered incidentally on a panoramic radiograph obtained for orthodontic documentation. In addition, the case herein described developed spontaneous remission, a situation not previously reported in the literature. Finally, we discuss relevant demographic, clinical, microscopic, immunohistochemical and treatment aspects of traumatic neuromas…
A rare case of oral multisystem Langerhans cell histiocytosis
2017
Langerhans cell histiocytosis (LCH) is a rare disorder characterized by high proliferation of Langerhans dendritic cells. LCH is a solitary or multifocal disease that primarily involves bone tissue and often affects children and young men. A 29 years-old Caucasian man was referred to the Oral Surgery Unit of George Eastman Hospital - Umberto I teaching hospital, with third degree mobility of teeth belonging to second, third and fourth quadrant. Panoramic radiograph showed multiple radiolucent areas with well demarcated borders on the right and left site of the mandible and on the left site of the maxilla. Extractions of compromised teeth and biopsy of the osteolytic tissue were performed. T…
Gossypiboma in the oral region: case report and literature review
2014
Gossypiboma is an inflammatory reaction to a foreign body, specifically composed of a cotton matrix left behind after surgery. The present study aims to present a case report of gossypiboma 23 years after a dental surgery and to make a literature review of the English language cases published on the issue. A 42-year-old woman was attended to evaluate complaints of pain on the right side of the maxilla. The patient reported that dental extractions in this region had been performed over a period of nearly 23 years. The panoramic radiograph demonstrated an opacity in the right maxillary sinus, which presented a spongiform aspect, irregularly shaped radiopaque image, as well as a rupture of the…
Photobiomodulation laser therapy in a Lenvatinib-related osteonecrosis of the jaw: A case report
2021
Background Medication-related osteonecrosis of the jaw (MRONJ) is a serious adverse drug reaction often presenting as a post-surgery complication that may interfere in the quality of the patient's life. In the last decade, additionally to bisphosphonates, other drugs have been associated with MRONJ including other antiresorptive, antiangiogenic or multitarget drugs such as levantinib. The data on MRONJ associated to lenvatinib is scarce with no guidelines for best management option. Our aim is to report a case of MRONJ associated with lenvatinib and the useful of a non-invasive management using local photobiomodulation (PBM) therapy with a 635nm diode laser. Material and methods A 61-year-o…
Langerhans’s cell histiocytosis in old subjects: two rare case reports and review of the literature
2012
doi: 10.1111/j.1741-2358.2012.00629.x Langerhans’s cell histiocytosis in old subjects: two rare case reports and review of the literature Background: Langerhans cell histiocytosis (LCH) is a proliferative disease of histiocyte-like cells that generally affects children; LCH onset is rare in adults; immunohistochemistry is essential to obtain the correct diagnosis, and treatment protocols are controversial. Objective: To describe two new cases of adult onset oral LCH. Case reports: Case 1: a 71-year-old woman, complaining of diffuse oral pain, presented with erythematous mucosal lesions; the panoramic radiograph and CT scan showed multiple mandible radiolucent areas. Immunohistochemical a…
Reduction rate by decompression as a treatment of odontogenic cysts
2017
Background: Odontogenic cysts are defined as those cysts that arise from odontogenic epithelium and occur in the tooth-bearing regions of the jaws. Cystectomy, marsupialization or decompression of odontogenic cyst are treatment approach to this pathology. The aim of this study was to evaluate the effectiveness of the decompression as the primary treatment of the cystic lesions of the jaws and them reduction rates involving different factors. Material and Methods: 23 patients with odontogenic cysts of the jaws, previously diagnosed by anatomical histopathology (follicular cysts (7) and radicular cysts (16)) underwent decompression as an initial treatment. Clinical examination and pre and pos…
