13. MICROSCOPIA DE FORÇA ATÔMICA IN SITU E MICRODUREZA DE DENTINA SUBMETIDA A SUBSTÂNCIAS QUELANTES / IN SITU ATOMIC FORCE MICROSCOPY AND MICROHARDENESS OF DENTIN THROUGHOUT THE CHELATION PROCESS
Instrumentation methods currently used in endodontic therapy create a residual layer composed of organic and inorganic material that frequently retains bacteria and their subproducts. The available methods to remove this smear layer include chemical etching, ultrasonic and laser techniques but none of these is completely efficient and there is no universal c

14. Avaliação clinica de terapia periodontal cirurgica utilizando aparelho ultra-sonico associado a escovação com tetracilina a 40%
The goal ofthe present investigation was to compare, clinically, two surgi cal procedures for root detoxification. Twenty patients diagnosed with adult periodontitis and showing at least four interproximal sites with a probing depth 5mm on anterior area were included. AlI patients received oral hygiene instruction and supragengival ultrasonic instrumentation

15. Implementation and validation of an ultrasonic tissue characterization technique for quantitative assessment of normal-tissue toxicity in radiation therapy
The goal of this study was to implement and validate a noninvasive, quantitative ultrasonic technique for accurate and reproducible measurement of normal-tissue toxicity in radiation therapy. The authors adapted an existing ultrasonic tissue characterization (UTC) technique that used a calibrated 1D spectrum based on region-of-interest analysis. They modifie

16. Ultrasonic enhancement of antibiotic action on gram-negative bacteria.
The effect of gentamicin upon planktonic cultures of Pseudomonas aeruginosa, Escherichia coli, Staphylococcus epidermidis, and Staphylococcus aureus was measured with and without application of 67-kHz ultrasonic stimulation. The ultrasound was applied at levels that had no inhibitory or bactericidal activity against the bacteria. Measurements of the MIC and

17. Changes in height of choroidal melanomas after plaque therapy.
Serial ultrasonic measurements of 82 uveal melanomas treated with brachytherapy plaques (cobalt-60 and iodine-125) and followed up for up to 141 months revealed that no two patients had identical patterns of change. The mean absolute change in tumour height after treatment was 1.8 mm at six months, 5.6 mm at 48 months for large tumours, and 0.9 and 1.9 mm fo

18. Fluoroscopically guided laser lithotripsy versus extracorporeal shock wave lithotripsy for retained bile duct stones: a prospective randomised study.
BACKGROUND AND AIMS: To compare extracorporeal shock wave lithotripsy (ESWL) and laser induced shock wave lithotripsy (LISL) of retained bile duct stones to stone free rate, number of therapeutic sessions, and costs. PATIENTS: Thirty four patients were randomly assigned to either ESWL or LISL therapy. The main reasons for failure of standard endoscopy were d

19. Peripheral organ perfusion augmentation during left ventricular failure. A controlled bovine comparison between the intraaortic balloon pump and the Hemopump.
Despite the use of inotropic therapy and the intraaortic balloon pump (IABP), inadequate peripheral organ perfusion and subsequent multiorgan failure from left ventricular dysfunction is a major cause of death following cardiac surgery. To compare the end-organ perfusion provided by the IABP with that of the recently developed Hemopump Cardiac Assist System,
