The purpose of this study was to determine if passive ultrasonic irrigation using finger spreaders was more effective than standard files in removing debris after root canal instrumentation. Eighty-five straight canals were instrumented and then passively ultrasonically irrigated with either fluted files or nonfluted finger spreaders for 3 minutes or 1 minute. Images of split canal lumens were ...

introduction: the aim of this study was to evaluate the effect of intra-canal calcium hydroxide (ch) remnants after ultrasonic irrigation and hand file removal on the push out bond strength of ah-26 and endosequence bioceramic sealer (bc sealer). methods and materials: a total of 102 single-rooted extracted human teeth were used in this study. after root canal preparation up to 35/0.04 mtwo rot...

AIM The case of a lower molar with apical periodontitis, which had previous root canal treatment and a fractured instrument in the distal root beyond the foramen, is presented. BACKGROUND The simultaneous presence of a foreign body (endodontic instrument or material) in periapical tissues and microorganisms in the root canal, are etiological factors in the formation or maintenance of a periap...

BACKGROUND One of the safety concerns when performing electrophysiological (EP) procedures under magnetic resonance (MR) guidance is the risk of passive tissue heating due to the EP catheter being exposed to the radiofrequency (RF) field of the RF transmitting body coil. Ablation procedures that use catheters with irrigated tips are well established therapeutic options for the treatment of card...

We have described a hydro-visco-implantation technique (simultaneous use of sodium hyaluronate and balanced salt solution) for wound-assisted intraocular lens (IOL) implantation and passive removal of ophthalmic viscosurgical device (OVD). In the technique, the capsular bag was filled approximately up to half with OVD, and anterior chamber was formed by bimanual irrigation cannula with continuo...

As indicated by standards of modern dentistry, the essence endodontic treatment is chemo-mechanical disinfection root canal system. The vital element this process irrigation canals with designated solutions as well activating them. This review article summarizes various techniques activation irrigants for such manual activation, thermal, pressure, sonic, ultrasonic, and laser in order to compar...
