Assessing bone density in prospective dental implant sites is crucial both for choosing the type and planning a drilling procedure that will ensure implant’s primary stability osseointegration. This study aimed to investigate possible differences between densities of various edentulous maxilla mandible. The was conducted on group forty partly patients who underwent radiological examination by s...

AIM The aim of this study was to evaluate the fracture resistance of various provisional crown materials using an in vitro model test system. METHODS AND MATERIALS In the present study polycarbonate crowns, prefabricated by the manufacturer (3M Polycarbonate Crown), and the temporary crowns, fabricated in the dental laboratory environment, were fabricated using bis-acryl composite (Protemp II...

BACKGROUND AND PURPOSE Little is known about the factors that determine recanalization after intravenous thrombolysis. We assessed the value of thrombus Hounsfield unit quantification as a predictive marker of stroke subtype and MCA recanalization after intravenous rtPA treatment. MATERIALS AND METHODS NCCT scans and CTA were performed on patients with MCA acute stroke within 4.5 hours of sym...

The study was to explore the feasibility of improving cone-beam CT (CBCT) number (corresponding to the Hounsfield units in computed tomography) consistency using a scatter-correction algorithm, with the aim of using CBCT images for treatment planning with density correction. A scatter correction algorithm was applied to a Varian OBI CBCT and an Elekta XVI CBCT, and was evaluated for improving C...

BACKGROUND The use of oral implants has been growing, and cone beam computerized tomography (CBCT) has become the method of choice for oral and maxillofacial radiology. OBJECTIVE To assess the accuracy of bone densitometry in two different CBCT devices in comparison with MDCT (multi-detector CT). METHODS Different concentrations of urografin, including 2.5%, 5%, 7.5%, 10%, 12.5%, were prepa...

Previous studies report positive effects of pentoxifylline (PTX) alone or in combination with other drugs on some pathologic bone diseases as well as an ability to accelerate osteogensis and fracture healing in both animal models and human patients. The aim of this present study was to evaluate the effects of PTX administration on Hounsfield unit and bone strength at catabolic response (bone re...
