Comparative effectiveness of root canal machining with modern ni-ti tools

Эндодонтия Today, 2020
The quality of endodontic treatment largely depends on the mechanical cleaning of the root canal, which is carried out in most cases by machine nickel-titanium instruments.

A comparative analysis of mechanical properties of different reciprocating Niti endodontic instruments

Annali di Stomatologia, 2023
Despite it is not questionable that static tests give readers only a partial view of the performance of an endodontic instrument they are currently accepted as valid ones to evaluate and compare mechanical properties of endodontic instruments. Therefore,

Granularity in reciprocity [PDF]

AI & SOCIETY, 2011
Witnessing in merging biological, social and algorithmic realities is crucial to trust, as modelled in the YUTPA framework. Being witness and bearing witness is fundamental to human interaction. System participation in human communities of practice challenges the notion of witnessing and therefore the ability to build trust. Nevertheless, through trial

Generalized Reciprocity

Journal of Magnetic Resonance, 1998
The remarkable theorem of reciprocity as described by D. I. Hoult and R. E. Richards (J. Magn. Reson. 24, 71 (1976)) may be generalized to account for the near, intermediate, and radiation zone fields of a magnetic dipole. This form of reciprocity may be important when the wavelength of the NMR signal is not large compared to the distance scale of the ...

Is Cone‐Beam CT Reliable for Apical Foramen Assessment? A Micro‐CT–Referenced Study

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the diagnostic accuracy of two cone‐beam CT (CBCT) dose protocols for identifying the number and trajectory deviation of apical foramina. Forty lower molars were scanned in Micro‐CT. Thereafter, all teeth were inserted into the mandible sockets and a titanium implant and an endodontically treated tooth with a cobalt ...

The use of modern technologies and the machine system Reciproc (VDW) during the revision of the root canals of a tooth with apical periodontitis: a case report

Эндодонтия Today
Endodontic retreatment in most cases is indicated with the development of apical periodontitis in teeth with previously treated root canals. This treatment is complicated by the fact that the root canals can be lined with any material: guttapercha pins ...
