When endodontic retreatment is needed, is using a reciprocating or rotary instrumentation system a better option? Research has produced conflicting results. To learn more, a new randomized clinical ...

Customization of rotary and linear motion systems improves performance, reduces costs and simplifies complex applications in manufacturing and medical devices. Advances in smart, compact and ...

In this meta-analysis, the rate of PP following canal preparation using either reciprocating or rotary instrument was assessed. The PP incidence odds ratio was 1.27, favoring rotary instruments.

Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...
