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 ...

Think of reciprocating motion, and cams — those kings of kinematic linkages — may come to mind. For good reason: Cams have been the traditional gold standard for reciprocating motion since the dawn of ...

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.

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 ...

Scientific American is the authority on science and technology for a general audience, with coverage that explains how research changes our understanding of the world and shapes our lives. First ...

They look harmless enough, but cams are some of the most complicated parts of your engine. In simple terms, cams are long, cylindrical-shaped shafts containing several irregular-shaped lobes that ...

Background: In endodontic therapy, continuous rotary instrumentation reduced debris compared to reciprocal instrumentation, which might affect the incidence of post-endodontic pain (PP). The aim of ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...
