Abstract :
Knowledge about internal anatomy plays a crucial role in the success of the root
canal treatment. Many studies on internal anatomy have repeatedly reported that
maxillary lateral incisors have only one canal. The primary aim of this article was
to describe successful non-surgical retreatment of a permanent maxillary lateral
incisor with two root canals and open apices. The treatment was carried out using
dental operating microscope and the canals were obturated with mineral trioxide
aggregate (MTA) as an apical plug. A review of literature was also conducted to
evaluate the anatomical variations of maxillary lateral incisors.
