It has been shown that unsuccessful root canal fillings influence the healing of periapical disease. Especially, in the case of over-extended root canal fillings, post-operative pain and inflammatory reactions of periapical tissue are observed. It is difficult to remove the over-extended gutta-percha safely and effectively by intra-canal procedures. In this report, gutta-percha over-extended into the periapical tissue of the root canal with excessively enlarged physiological foramen was removed by means of intra-canal instruments, K-files and barbed broaches. The barbed broaches used in this report weree adjusted short, and the gutta-percha was removed effectively. The findings after 1 year of the root canal treatment showed that local conditions were good and the roentgenologic findings were improved completely.
