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.
本研究的目的是评估根管充填时牙胶尖主尖的选择。根据标准技术对总共258个根管进行预备并选择主尖。根管被分为两组：第一组，主尖与用于根尖预备的器械编号相同，且未进行任何额外的操作程序；第二组，主尖编号不对应或进行了额外的操作程序。第一组有162个根管，第二组仅有96个根管，结果虽有差异但无统计学意义。
