Abstract

This study is a retrospective analysis of the outcome of initial nonsurgical root canal treatment of teeth with open apices, obturated with mineral trioxide aggregate when no apical barrier existed. One hundred sixteen patients from a single private endodontic office were treated between 1999 and 2006. Treatments on 144 teeth were completed either in one (92/144) or two visits with an interim calcium hydroxide interappointment medication (52/144). Fifty-four percent (78/144) of the teeth were available for recall (60.3% one visit and 39.7% two visits). The maximum time to recall was 4.87 years. The mean time to recall was 19.4 months. Of the cases recalled for period of 1 year or longer, 93.5% of teeth treated in 1 visit healed, and 90.5% of teeth treated in 2 visits healed.
