Dental Hospital

A 44-year-old male was referred to the Department of Orthodontics at Manchester Dental Hospital. He presented with pain from his heavily restored, lower right second premolar, which had an apical supplemental tooth, visible radiographically. The dentist queried whether the second premolar tooth could be extracted and the supplemental tooth aligned in its place. Clinical examination revealed no relevant abnormalities. The family and medical history were non-contributory. Panoramic tomography revealed multiple supplemental supernumerary teeth in the canine and premolar regions. Cone beam computed tomography and multidisciplinary team input were required to plan the treatment for this unusual case. CPD/Clinical Relevance: These findings highlight the management and treatment options for a case of non-syndromic, multiple supernumerary teeth. Consideration must be given to the risk of damage to adjacent structures if surgically removing supernumerary teeth, and the risk that supernumerary teeth may be ankylosed and not amenable to alignment within the arch.

Unerupted Teeth

ABSTRACT Pre-eruptive intracoronal resorption (PIR) is a rare lesion that occurs within the dentin of the crown on unerupted teeth. The aim of this article is to report two rare cases of a PIR in impacted canine using cone beam computed tomography (CBCT). High resolution CBCT images (Prexion 3D) were indicated for evaluating of the non-erupted tooth, claiming no other related signs or previous historyto be considered. In the first case, the images revealed an impacted and mesioinclined superior canine. In the coronary portion, it was observed an irregular hypodense lesion, involving the dentin, enamel tissue, and communication with the external surface of the tooth. In the second case, the images showed an impacted superior canine in the vertical position. It also revealed a hypodense lesion with poorly defined limits envolving the dentin, which extends over the crown. In both cases, the tooth was not in contact with the adjacentlateral tooth. Therefore, PIR in impacted teeth is rare, which is frequently diagnosed through routine radiographs. Additionally, CBCT seems to be an invaluable tool for providing accurate information about the exact topography, relationships with adjacent structures, helping, therefore, on the appropriate treatment planning.

Introduction Onodi cells are the most posterior ethmoid air cells, and extend superolaterally to the sphenoid sinus. The identification of Onodi cells is essential to because they can have some significant anatomic variations and relationships to vital adjacent structures, like the optic canal, the sphenoid sinus, and the internal carotid artery. Objective The present study aimed to assess the prevalence of Onodi cells and their position with respect to sphenoid sinus. To the authors' best knowledge, this is the first study that uses cone-beam computed tomography (CBCT) to assess the prevalence and position of Onodi cells. Methods We collected CBCT scan records from November 1st, 2016, to July 31st, 2017; the patients who fulfilled the eligibility criteria were included in the present study. The CBCT scans were reviewed by two independent observers. The descriptive statistics was performed using the Statistical Package for the Social Sciences (SPSS, SPSS, Inc., Chicago IL, US) software, version 17.0. A cross-tabulation of gender with the presence and position of Onodi cells was evaluated using the Chi-squared (χ2) test. The inter- and intraobserver agreements were evaluated using Kappa (κ) statistics. Results Onodi cells were identified in 86 (42.8%) out of 201 patients. A subgroup analysis revealed that Onodi cells were present in 45 (43.3%) female and 41 (42.3%) male patients. The position of the Onodi cells was superior with respect to the sphenoid sinus in 43 (50%) of the patients, superolateral in 36 (41.9%), and lateral to the sphenoid sinus in 7 (8.1%) of the patients. Conclusion The present study indicated a high prevalence of Onodi cells, with approximately equal distribution among males and females, and mostly superior in position in relation to the sphenoid sinus.

In this article, we evaluate the effectiveness of Cone Beam Computed Tomography, through a case study, in assessing the complication of intracranial bleeding during an endovascular treatment of brain arteriovenous malformation when compared to Multislice-Detector Computed Tomography performed immediately after the procedure. The image quality of Cone Beam Computed Tomography has enough diagnostic value in differentiating between haemorrhage, embolic materials and the arteriovenous malformation nidus to facilitate physicians to decide for further management of the patient.
