The aim of the research is to determine if cone beam computerized tomography reconstructed panoramic radiography viewed in two different focal trough shapes, and three different focal trough widths changes the ability to identify high risk...
Objective . To compare the in vitro reliability and accuracy of linear measurements between cephalometric landmarks on CBCT 3D images with varying basis projection images to direct measurements on human skulls. Methods . Sixteen linear dimensions...

CBCT in endodontics demonstrates anatomic features in 3D that intraoral, panoramic, and cephalometric images cannot. CBCT units reconstruct the projection data to provide interrelational images in three orthogonal planes (axial, sagittal, and...
A blinded observational cross-sectional in vitro study was conducted to compare the diagnostic accuracy of observers viewing images made using cone beam computerized tomography (CBCT), panoramic radiography and linear tomography. The sample...
Introduction: The study investigated dimensional relationships between the sphenoid and maxillary sinuses and other selected craniomaxillofacial structures by using traditional cephalometric and volumetric procedures based on cone beam computed...
Potential dental implant site assessment is initially determined clinically. Subsequent radiographic assessment also provides information about the quantity of available bone. It was hypothesized that the use of radiographic markers in mandibular...
Computer-aided minimally invasive surgery (MIS) has progressed significantly in the last decade and it has great potential in surgical planning and operations. To limit the damage to nearby healthy tissue, accurate modeling is required of the...
The aim of the study was to determine the incidence and imaging characteristics of soft tissue calcifications on cone beam computed tomography (CBCT). 556 CBCT image datasets were reviewed and 308 included. The following conditions were recorded:...
The purpose of this project was to compare the accuracy and reliability of linear measurements made on 2D projections and 3D reconstructions using Dolphin 3D software (Chatsworth, CA) as compared to direct measurements made on human skulls. The...
Determining the etiology of skeletal malocclusion is an important diagnostic step in treatment planning patients with maxillofacial anomalies. Aims: To describe cranial base morphology using cone beam computed tomography (CBCT) images and correlate...
A combination of three techniques – high resolution micro computed tomography (micro CT) scanning, Archimedes-based volume fraction measurement and serial sectioning or milling – were used to determine the volume fraction, trabecular thickness,...
Recent advances in understanding the molecular mechanisms of mutagenesis indicate that most mutations are dependent on the activity of translesion synthesis DNA polymerases. The impact of reducing the level of these polymerases on mutagenesis and...
Idiopathic pulmonary fibrosis (IPF) is a fibrotic lung disease with poor prognosis.
To address this disease broadly, the candidate engaged in clinical work, literature
analysis, database analysis, and laboratory work. The clinical work culminated...
Lung cancer is the deadliest type of known cancer in the United States, claiming hundreds of thousands of lives each year. However, despite the high mortality rate, the 5-year survival rate after resection of Stage 1A non–small cell lung cancer...
The field of bone densitometry has grown rapidly, particularly in the past 15 years. Many techniques are now available from which the physician may choose. The focus of this research is on Dual-Energy X-Ray Absorptiometry (DXA) and Quantitative...

Lumbar arthrodesis or spinal fusion is usually performed to relieve back pain and regain functionality from ruptured discs, disc degenerative disease, trauma and scoliosis. Metal rods are often fixed to the spine with screws or hooks, while fusion...
In the age of high-throughput molecular biology techniques, scientists have incorporated the methodology of in-situ hybridization to map spatial patterns of gene expression. In order to compare expression patterns within a common tissue structure,...
