Retreatodontics and ultrasonics
Journal of Endodontics, 1988Retreatment of endodontically failing teeth is commonin most endodontic practices today. Two case reports are presented in which ultrasonics was used for retreatment. It is suggested that ultrasound can ease and, to some extent, simplify retreatment of some endodontic failures.

Ligand binding influences the dynamics of the DNA helix in both the binding site and adjacent regions. This, in particular, is reflected in the changing pattern of cleavage of complexes under the action of ultrasound. The specificity of ultrasound-induced cleavage of the DNA sugar-phosphate backbone was studied in actinomycin D (AMD) complexes with ...

Surgical Endoscopy, 1994
Following its development for cataract surgery, and gaining widespread use in neurosurgery and liver resection, ultrasonic dissection has been adapted for laparoscopic use. The turbulence, heat, and pressure generated by imploding bubbles disrupts tissues high in water content.

Journal of Clinical Periodontology, 1974
Abstract The vibrating tips of ultrasonic instruments have been shown to remove deposits mechanically. Calculus removal is equally effective with ultrasonic or hand instruments, whereas stain removal has been shown to be better with the former. It has been observed that ultrasonic instruments remove heavy supragingival calculus faster than hand ...

Transactions of the Institute of Measurement and Control, 1979
Recent accounts of ultrasonic flowmeters usually concentrate on either transit time or Doppler types. Although these are the most common types in use today, at least six other types exist. Part 1 of this two-part paper describes the physical principles of eight types of ultrasonic flowmeters, along with some general considerations (flow profile ...
