Abstract

Root-end restoration using Mineral Trioxide Aggregate (MTA) was performed on two patients who received root canal treatment but had poor progress. In one case, a large amount of Calcium hydroxide(Ca (OH)2), a intracanal medicament, escaped from a wide-open apex, stagnated around the tooth root, and the apical lesion did not disappear. The other case is a case where the root canal at the apical part has a complicated anatomical form, the root canal cannot be tightly packed, and the apical lesion has not disappeared. Root-end restoration using MTA was performed on these two cases, and improvement of the lesion was confirmed. From these results, it was shown that Root-end restoration using MTA is effective for patients with poor prognosis of root canal treatment for which the apical portion cannot be tightly packed for various reasons. Keywords: Mineral Trioxide Aggregate; MTA; Root-end restoration
