With their progressive taper design and system-based efficiency, ProTaper Universal treatment files are synonymous with exceptional performance. In general, as few as three ProTaper Universal files achieve a fully tapered canal exhibiting a uniform shape. And now, you can achieve these shapes with more precision and safety. The difference is a more rounded tip on all ProTaper Universal finishing files and improved flexibility on the larger finishing files that enable them to precisely follow the canal anatomy.
