results although the antibacterial effect of 16 ppm aqueous ozone using a manual technique had an insufficient effect, its ultrasonic application technique resulted in complete disinfection in the root canals. conclusions the bactericidal activity of high concentration of aqueous ozone combined with ultrasonic application technique showed efficacy similar to that of 5.25% naocl in root canals. ...

Ultrasound is widely used in the treatment of materials. Its applications melt processing, surface hardening or finishing, metal forming, welding, etc., are well known and have been reviewed numerous review articles books. Among ultrasound-assisted processes, direct action ultrasonic waves on structure properties bulk materials special interest. Ultrasonic induce oscillating shear stresses whic...

INTRODUCTION Biofilms of resistant species such as Enterococcus faecalis pose a major challenge in the treatment of root canals with established periapical disease. This study examined the effects of gaseous ozone delivered into saline on biofilms of E. faecalis in root canals of extracted teeth with and without the use of passive ultrasonic agitation. METHODS Biofilms of E. faecalis were est...

One approach to enhance the disinfection of root canals in endodontic treatment is ultrasonic irrigation with sodium hypochlorite. Reactive oxygen species, such as hydroxyl radical, are generated by biological defense systems to kill invading bacteria. Ultrasonic irrigation with hydrogen peroxide may be a promising option to increase hydroxyl radical generation. We examined the bactericidal eff...

Treatment options specifically targeting tumour cells are urgently needed in order to reduce the side effects accompanied by chemo- or radiotherapy. Differences in subcellular structure between tumour and normal cells determine their specific elasticity. These structural differences can be utilised by low-frequency ultrasound in order to specifically induce cytotoxicity of tumour cells. For fur...

Treatment of milk with low-frequency ultrasound significantly increased the total bacterial counts and the counts of enterococci, coliforms, and staphylococci. Warming diluted milk for about 12 min at 30 or 40 C increased the counts of some organisms, but the heat produced by ultrasonic treatment did not account entirely for its effect. The ultrasonic effect was related to the energy output of ...

INTRODUCTION Despite a growing popularity of noninvasive ultrasonic lipolysis procedure, there is a lack of evidence about the efficacy of this method. This study was performed to evaluate the efficacy of focused ultrasonic lipolysis on abdominal cellulite treatment. METHODS Twenty-eight consecutive subjects (age: 37.8 ± 8 years) underwent weekly transdermal focused ultrasonic lipolysis (Med ...

ultrasonic technology as an innovative technology may be used for water and wastewater treatment for pollution removal. this technology acts as an advanced oxidation process. application of this technology leads to the decomposition of many com­plex organic compounds to much simpler compounds during physical and chemical compounds during cavitation proc­ess. in this article review, some applica...
