Twenty samples of each size designation of finger spreaders and accessory gutta-percha cones were randomly selected from a proprietary standardized system currently used for lateral condensation procedures. Their diameters were measured with a calliper and their morphological variations at the areas of their apical thirds were analyzed with the scanning electron microscope. Results of the measurements indicated that there were high degrees of variation between all spreaders and their corresponding accessory gutta-percha cones (p < 0.001). SEM examination showed the presence of many morphologic irregularities and lack of uniformity between spreaders and cones of the same size. Our results emphasize the need for more precise criteria to fulfill the requirements of standardization by the manufacturer to provide an accurate method for root canal obturation.
