AIM To assess and compare the shaping potential of manual NiTi K-files and Rotary ProTaper instruments in narrow canals using CT. OBJECTIVE To assess the shaping potential of manual NiTi K-files and Rotary ProTaper and analyzing the final outcome of shaped canals using CT and determining different variables, like • Working time • Change in volume • Change in cross-sectional area. MATERIALS ...

OBJECTIVES To compare daily energy expenditure between RA patients and matched controls, and to explore the relationship between daily energy expenditure or sedentariness and disease-related scores. METHODS One hundred and ten patients with RA and 440 age- and sex-matched controls were included in this study. Energy expenditure was assessed using the validated physical activity (PA) frequency...

A Trusted Execution Environment (TEE) provides an isolated hardware environment for sensitive code and data to protect a system’s integrity confidentiality. As we discovered, programmers tend overuse TEE protection. When they place non-sensitive in TEE, the trusted computing base (TCB) grows unnecessarily, leading long execution latencies large attack surfaces. To address this problem, first st...

OBJECTIVES Transcatheter closure of a secundum atrial septal defect (ASD II) has become an effective alternative for surgical treatment. In this study we evaluated the correlation between the two-dimensional transoesophageal echocardiographic (2D TEE) sizing of ASDs and the actual diameter of occluders in patients undergoing device closure. METHODS The records of 54 patients who underwent tra...

background and aims. this study aimed to investigate release of nickel ion from three types of nickel-titanium-based wires in the as-received state and after immersion in a simulated oral environment. materials and methods. forty specimens from each of the single-strand niti (rematitan “lite”), multi-strand niti (speed supercable) and copper niti (damon copper niti) were selected. twenty specim...

Background and Purpose—Findings on transesophageal echocardiography (TEE) after ischemic stroke predict recurrent embolic events and prompt therapy; however, the additive predictive power of TEE findings on long-term mortality is unknown. Our goal was to study the impact of TEE findings on all cause mortality in ischemic stroke patients referred for TEE. Methods—We reviewed 245 consecutive pati...

Over the past few decades, transesophageal echocardiography (TEE) has evolved from one-dimensional imaging using a probe with a single-crystal, M-mode transducer to two-dimensional imagingwith phased-array transducers and now three-dimensional (3D) imaging with matrix array transducers. Current 3D imaging probes are vastly superior to the earlier technique of using multi-plane TEE imaging to re...

AIMS Accurate visualization of the distal ascending aorta (DAA) can guide the surgical management and hence prevent dislodgment of atherogenic emboli during cardiac surgery. Conventional transoesophageal echocardiography (TEE) has a poor sensitivity; modified TEE was previously shown to accurately visualize atherosclerosis of the DAA. We studied the added value of modified TEE beyond the patien...

BACKGROUND The clinical implications of a negative multiplane transesophageal echocardiography (TEE) have not yet been reported. We aim to determine the negative predictive value (NPV) of a negative multiplane TEE in patients with suspected infective endocarditis (IE). METHODS AND RESULTS We identified 83 consecutive patients with suspected IE and negative multiplane TEE from our echocardiogr...
