A rare primordial odontogenic tumor in a pediatric patient.

Primordial odontogenic tumor (POT) is a rare, benign pediatric lesion that was first included in the 2017 edition of WHO Classification of Head and Neck Tumours. At that point, only 7 cases had been described in the literature; a total of 23 cases have been reported to date. This case report adds to that total by describing a case of POT in a 12-year-old girl and reviews the characteristics of this neoplasm in order to better characterize its clinical, radiographic, and histologic features and increase dentists' awareness of POT.

Digital intraoral imaging: analysis of retakes and reduction in radiation exposure using rectangular collimation.

The purposes of this study were to examine the distribution and extent of retakes with digital intraoral imaging when operators transitioned from using round to rectangular collimators and to determine the effect of collimator shape on radiation exposure to patients. This study was conducted using digital intraoral radiographic data from 2018 to 2019 in a dental school radiology clinic. Digital intraoral radiography was performed with round collimators during 2018 and then with rectangular collimators in 2019 with the same cohort of students.

Case of Mönckeberg arteriosclerosis in the carotid, facial, and lingual arteries: a potentially serious incidental finding in CBCT.

Calcifications in the tunica media (middle layer of the arterial wall), classified as Mönckeberg arteriosclerosis, are more prevalent in older patients and patients with diabetes and/or chronic kidney disease. Mönckeberg arteriosclerosis has prevalence rates of 13.3% and 6.

Molar-incisor malformation: Eight new cases and a review of the literature.

Background: Molar-incisor malformation (MIM) is a recently described dental abnormality. While MIM mimics dentin dysplasia, it presents in a localized pattern. Furthermore, it is speculated that MIM is caused by significant early-life medical history.

TMJ arthrosis: does the occlusal relationship really interfere? A comparison between cone beam computed tomography and dried skulls.

The aim of this study was to investigate the association between condylar bone morphological characteristics with occlusal conditions. Besides the study will compare the tomography images with the real condition in 122 temporomandibular joints from 61 skulls. The occlusal conditions were evaluated by number of teeth missing, measurement of overjet and overbite, in millimeters, and presence or absence of crossbite, openbite and dental rotation.

Mandibular condylar dimensions: Correlation between 3D tomography and dried skull measurements.

Objective Compare the anatomical dimensions of mandibular condyles with the same CBCT measurements. Methods Four landmarks were identified on the condyles of dried skulls and are measured with their corresponding areas in CBCT images: Right Width of Condyle (RW), Left Width of Condyle (LW), Right Length of Condyle (RL), and Left Length of Condyle (LL). Results With respect to direct measurements on the dry skulls, statistically significant differences were found between sexes (p < 0.

Garlic burn of the oral mucosa: A case report and review of self-treatment chemical burns.

Background And Overview: Inappropriate self-treatment with topically applied therapeutic or nontherapeutic agents frequently results in mucosal burns. Although such chemical burns typically are associated with misuse of analgesics, investigators also have reported them in conjunction with topical application of a variety of other agents.

Case Description: The authors report an unusual case of a 49-year-old man seeking care for maxillary tooth pain who had an oral mucosal burn of the maxillary vestibule caused by topical application of crushed raw garlic.

Intraoral Pseudo-Onion Bulb Intraneural Proliferations in a Patient with Hemimandibular Hyperplasia: A Case Report and Review of the Literature.

This report and review of the literature describes a case of benign intraoral lesions of perineurial origin in a patient with symptomatic hemimandibular hyperplasia causing partial denture soreness. Perineuriomas are a benign peripheral nerve sheath tumor composed of perineurial cells. Intraoral perineuriomas are an extremely rare entity.

Cervicofacial subcutaneous emphysema: a clinical case and review of the literature.

Cervicofacial subcutaneous emphysema is a known, rare complication of both dental and surgical procedures. Cervicofacial subcutaneous emphysema arises when air is forced beneath the tissues, leading to swelling, crepitus on palpation, and the potential of the air to spread along the fascial planes. This report presents a case of cervicofacial subcutaneous emphysema in a patient who had undergone surgical extraction of the mandibular right first molar.

The reliability of tablet computers in depicting maxillofacial radiographic landmarks.

Purpose: This study was performed to evaluate the reliability of the identification of anatomical landmarks in panoramic and lateral cephalometric radiographs on a standard medical grade picture archiving communication system (PACS) monitor and a tablet computer (iPad 5).

Materials And Methods: A total of 1000 radiographs, including 500 panoramic and 500 lateral cephalometric radiographs, were retrieved from the de-identified dataset of the archive of the Section of Oral and Maxillofacial Radiology of the University Of Connecticut School Of Dental Medicine. Major radiographic anatomical landmarks were independently reviewed by two examiners on both displays.

Mixed radiopaque and radiolucent lesion of the maxillary sinus: a radiographic challenge.

This article describes 3 patients, each of whom presented with an asymptomatic mixed radiopaque and radiolucent lesion of the maxillary sinus associated with a nonvital tooth. Based on the radiographic findings, a diagnosis of a collapsed (ruptured) radicular cyst was rendered in each case. A tissue biopsy was performed in 1 case, and the results supported the diagnosis.

Is Computed Tomography an Adequate Imaging Modality for the Evaluation of Juvenile Ossifying Fibroma? A Comparison of 2 Imaging Modalities (Computed Tomography and Magnetic Resonance Imaging).

Purpose: Given the problems of overuse of medical technology and the current burden of health care cost in the United States, it is important to establish clear imaging guidelines to diagnose conditions such as juvenile ossifying fibroma (JOF). This study compared the efficacy of computed tomography (CT) and magnetic resonance imaging (MRI) in the evaluation of JOF and thus could aid establishing such guidelines.

Materials And Methods: Radiologic criteria were established by 2 radiologists to compare the efficacy of CT and MRI in the evaluation of JOF.

Ameloblastic carcinoma of the mandible manifesting as an infected odontogenic cyst.

Ameloblastic carcinoma (AC) is a rare malignant odontogenic tumor. Although most ACs appear to originate de novo, some cases originate from a pre-existing ameloblastoma. This article presents the case of a 69-year-old man with an AC in the left body of the mandible.

Psammomatoid and trabecular juvenile ossifying fibroma: two distinct radiologic entities.

Objective: Evaluate and compare the radiologic features of psammomatoid versus trabecular variants of juvenile ossifying fibromas.

Study Design: Twelve of fifteen cases of juvenile ossifying fibroma of the craniofacial bones, retrieved from our pathology archives for the period between 2002 and 2013, had available preoperative computed tomography (CT) scans. The radiologic features of each case were analyzed and compared by two neuroradiologists and one oral and maxillofacial radiologist, each blinded to the histopathologic diagnosis.
