[Mathematical description of human root canal curvatures].
There is a necessity of a mathematical formula for the description of root canal curvatures. The aim of this study was to give a mathematical description of root canal forms. The measurements of 60 roots were conducted on isometric radiographs taken from the clinical view. Seven points of the imaginary axis were approximated using fourth-degree polynomial functions. Fourth-degree approximation for the description of the shape of root canal curvatures proved to be exact and reliably repeatable. This method may serve the classification of root canal forms as well as the description of the spatial curve of root canals.
