Novel modified quantitative index for cone-beam CT assessment of medication-related osteonecrosis of the jaw - comparative analysis with original index.

Purpose: The main research goal was to address the critical need for an objective and quantitative index to describe the nature and extent of radiographic features of medication-related osteonecrosis of the jaw (MRONJ) lesions and complement the descriptive radiographic interpretation of the lesion and its clinical assessment.

Method And Materials: A retrospective review of MRONJ patients assessed at our institution was performed to compare the Composite Radiographic Index (CRI), identified from a prior scoping review, with a proposed modification, the Modified CRI index ('Mod-CRI'). The Mod-CRI index was weighted to assign a higher score for diffuse radiographic involvement of a given lesion, and delineated MRONJ lesions into those with 'high' and 'low' severity.

Cone Beam Computed Tomography (CBCT) Evaluation of Alveolar Bone Thickness and Root Angulation in Anterior Maxilla for Planning Immediate Implant Placement.

Objective:  This retrospective study aimed to measure the labial, palatal, mesial, and distal bone thickness around maxillary central and lateral incisors and canines and height from crest to apex, using cone beam computed tomography (CBCT) images and compare the results based on gender. The second objective of the study was to measure root angulation on CBCT images and its relation with the labial cortical thicknesses.  Material and Methods: After the Institutional Review Board (IRB) approval, a total of 140 CBCT volumes were included in this study according to the set criteria.

Effect of Mandible Phantom Inclination in the Axial Plane on Image Quality in the Presence of Implant Using Cone-Beam Computer Tomography.

Purpose To assess the effect of 30° phantom inclination on image quality in the presence of an implant using cone-beam computed tomography (CBCT). Materials and methods Three series of eight scans were taken and categorized by a range of 87-90 kVp and 7.1 mA, and 8 mA.

Magnetic Resonance Imaging Features of Progressive Condylar Resorption: A Case Report.

Progressive condylar resorption is a dysfunctional remodeling of the temporomandibular joint of unknown origin. It usually manifests in young girls and causes reduced ramus height, loss of condylar volume, steep mandibular angle, limited jaw motion, and pain. On magnetic resonance imaging, the condition is associated with anterior disc displacement with or without reduction.

Quantitative indices for cone-beam CT assessment of Medication-Related Osteonecrosis of the Jaw - a scoping review.

Objectives: It is not unusual for Medication-related osteonecrosis of the jaw (MRONJ) lesions that have similar clinical presentation and staging to have dissimilar radiographic extent of disease. The aim of this review was to explore the published scientific literature for quantitative indices that describe the cone-beam computerized tomography (CBCT) radiographic features of MRONJ lesions and assess their clinical utility.

Method And Materials: A scoping review of the literature was performed to identify quantitative indices developed to describe the CBCT radiographic features of MRONJ lesions.

Accuracy and Reliability of CBCT Compared to Clinical Probing in Detection of Trifurcation Defects: An In Vivo Study.

Background: Furcation defects are areas of pathological bone resorption in multirooted teeth. The aim of the study was to compare the measurements of trifurcation bone loss, measured using CBCT, versus clinical measurements in order to evaluate the efficacy of CBCT as an adjunctive diagnostic tool. .

Physiologic and Pathologic Calcifications of Head and Neck Significant to the Dentist.

This article aims to help the practitioner identify structures found in routine three-dimensional imaging studies of the head and neck region and understand their significance and possible need for intervention. The prevalence of advanced imaging in dental practice, especially cone beam computed tomography, highlights the need to recognize and identify various high-density structures that are, in fact, soft tissue calcifications or alterations of normal bony anatomy. The wide range of these findings includes both benign and malignant pathologic entities as well as age-related calcifications and remodeling of normal anatomic structures and dystrophic calcifications.

Cone beam computed tomographic-Based retrospective study on newark population for the assessment of distance between incisive canal and maxillary central incisors: Clinical implications.

Aims: To calculate the relative distance between the incisive canal and maxillary central incisors using cone beam computed tomography (CBCT) and utilize the results in treatment planning in a clinical setting.

Methods And Materials: A retrospective study was conducted on CBCT taken for other purposes in the Oral and Maxillofacial Radiology Department. All the quantitative measurements were performed between the incisive canal and both maxillary central incisors using CBCT on 61 subjects.

Maxillary ameloblastoma in an 8-year-old child: A case report with a review of the literature.

Ameloblastoma is a benign locally invasive tumor with a high tendency to recur. It is considered rare in the pediatric population, with most cases diagnosed in the third to fifth decades of life. Approximately 80% of ameloblastomas occur in the molar and ramus region of the mandible, while 20% of cases occur in the maxillary posterior region.

Clinical and radiological findings in a severe case of cleidocranial dysplasia.

Cleidocranial dysplasia (CCD) is a rare congenital autosomal dominant condition, causing hypoplasia of the clavicle, abnormal formation of teeth, skeletal and craniofacial bones. CCD is caused by the mutation of RUNX2/CBFA1 present in the short arm of chromosome 6 at position 21.1, a transcription factor essential for the formation of teeth, cartilage and bone.

Interpretation of cone beam computed tomography volumetric data: How to report findings?

Cone beam computed tomography (CBCT) was introduced to the dental profession at the beginning of the new millennium and has become an integral part of dental practice, especially within the surgical specialties. With advances in technology and the introduction of new-generation digital detectors, the concomitant increase in pixel resolution provided the ability to discern fine details of the anatomy. This article focuses on the methodology of CBCT interpretation and reporting.

Diagnostic Imaging of Malignant Tumors in the Orofacial Region.

Though rare, malignancies of the orofacial region often have serious consequences. Malignancies of the orofacial region are typically discovered during a clinical examination or from a patient complaint. Initial discovery from a radiograph is rare.

Accuracy of digital periapical radiography and cone-beam computed tomography in detecting external root resorption.

Purpose: The purpose of this study was to evaluate and compare the efficacy of cone-beam computed tomography (CBCT) and digital intraoral radiography in diagnosing simulated small external root resorption cavities.

Materials And Methods: Cavities were drilled in 159 roots using a small spherical bur at different root levels and on all surfaces. The teeth were imaged both with intraoral digital radiography using image plates and with CBCT.
