The conventional principle of root canal obturation is to make the gutta percha(GP) ratio high and the sealer ratio low. Many studies suggested that continuous wave technique(CWT) was superior to cold lateral compaction(CLC) in teeth with complex anatomical structures, but CWT also has many disadvantages. With the recent development of the calcium silicate based sealer(CSS), single cone technique(SCT) is back in the spotlight as a root canal obturation technique. Due to the advantages of clinical convenience, many dentists obturate root canal by SCT. When obturating the root canal by SCT, it is likely that the quality of the root canal obturation will decrease as compared to CLC or CWT depending on tooth anatomic complexities, and it is difficult to remove the CSS from root canals in the cases of retreatment. Therefore, it is recommended to be careful in selecting case when obturating the root canal by SCT.
