A wide range of anatomical variations is seen below the orifice level, but 2 basic groups can be identified: those with a single ribbon-like C-shaped canal from orifice to apex and those with 3 or more distinct canals below the C-shaped orifice. Debridement and obturation are both ...
The results illustrated that C-shaped canals in mandibular second molars can vary in number and shape along the length of the root with the result that debridement, obturation, and restoration in this group may be unusually difficult. 展开 ...

Large deflections of C-shaped springs are studied using the theory of the Elastica. The resulting nonlinear differential equation is integrated by a new homotopy method. It is found that the force-displacement curve is decidely nonlinear and depends heavily on the free shape of the spring. The ...
