title: The choice of the master cone: a comparative study.
abstract: The aim of this study was to evaluate the choice of the gutta-percha master cone during root canal filling. A total of 258 root canals were instrumented according to standard techniques and master cones were selected. The root canals were divided into two groups: group I, in which the master cone was of the same number as the instrument used for apical preparation without any additional operative procedure, and group II in which the master cone did not correspond in number or if additional operative procedures were performed. Group I consisted of 162 root canals and group II consisted of only 96, a larger but not statistically significant result.
