ABSTRACT Maxillary canine and first premolar transposition is a complicated dental anomaly to treat, especially if the clinician's goal is to orthodontically move the canine into its normal position. Early diagnosis with cone-beam computed tomography simplifies the treatment of this pathology. This case report describes a patient with bilateral transposition, one complete and the other incomplete, involving the maxillary canine and the first premolar (Mx.C.1P). The orthodontic treatment involved the correction of both transpositions. In the complete transposition, the traction was mesial and upward to move the canine into a more apical position with a wider dentoalveolar process for easier crown interchange.

Dimensional Classification

The aim of this study was to evaluate both intra- and interoperator reliability of a radiological three-dimensional classification system (KPG index) for the assessment of degree of difficulty for orthodontic treatment of maxillary canine impactions. Cone beam computed tomography (CBCT) scans of fifty impacted canines, obtained using three different scanners (NewTom, Kodak, and Planmeca), were classified using the KPG index by three independent orthodontists. Measurements were repeated one month later. Based on these two sessions, several recommendations on KPG Index scoring were elaborated. After a joint calibration session, these recommendations were explained to nine orthodontists and the two measurement sessions were repeated. There was a moderate intrarater agreement in the precalibration measurement sessions. After the calibration session, both intra- and interrater agreement were almost perfect. Indexes assessed with Kodak Dental Imaging 3D module software showed a better reliability inz-axis values, whereas indexes assessed with Planmeca Romexis software showed a better reliability inx- andy-axis values. No differences were found between the CBCT scanners used. Taken together, these findings indicate that the application of the instructions elaborated during this study improved KPG index reliability, which was nevertheless variously influenced by the use of different software for images evaluation.

History Of

Invasive cervical resorption (ICR) is an insidious, aggressive, and asymptomatic form that can lead to destruction and even loss of the dental unit. ICR is somewhat uncommon, but it can affect any tooth, with the maxillary central incisors being the most affected. Even after numerous studies, the etiology is still unclear. There are some predisposing factors, including orthodontic treatment, trauma, and internal tooth whitening, which may occur in isolation or in conjunction with each other. This article reports a clinical case of ICR class 3 with a rosy discoloration at the cervical margin and the presence of a fistula associated with a history of trauma. This suspicion was raised after radiographic examination and confirmed by cone-beam computed tomography (CBCT), with treatment via an internal approach and endodontic treatment involving debridement of the resorptive areas and filling with a bioceramic repair material and suturing. After treatment, the patient remained asymptomatic, but the fistula was no longer present. Prospective observation at 10 months showed bone formation in the middle third and well-adapted material in the cervical region, with no resorptive tissue present.

ABSTRACT Transposition of maxillary teeth is an eruptive disturbance occurring in approximately 1 of every 300 orthodontic patients. Such cases are frequently very challenging in terms of treatment planning and orthodontic management. The canine is one of the most commonly transposed teeth, ectopically positioned with either the lateral incisor or the first premolar. This case report illustrates unique orthodontic treatment, describes treatment procedures, and presents the final outcome of bilateral maxillary canine-lateral incisor complete transpositions in which the involved teeth were moved to their clinically normal position in the dental arch without extracting premolars.

The purpose of this article is to present the case of maxillofacial trauma patient with maxillary sinus fracture diagnosed with cone-beam computed tomography (CBCT) and to explore the applications of this technique in evaluating the maxillofacial region. A 23-year-old male patient attempted to our clinic who had an injury at midface with complaints of swelling, numbness. The patient was examined before in emergency center but any diagnosis was made about the maxillofacial trauma. The patient re-examined clinically and radiographically. A fracture on the frontal wall of maxillary sinus is determined with the aid of CBCT. The patient consulted with the department of maxillofacial surgery and it is decided that any surgical treatment was not necessary. The emerging technique CBCT would not be the primary choice of imaging maxillofacial trauma. Nevertheless, when advantages considered this imaging procedure could be the modality of choice according to the case.
