This study is a prospective randomized controlled study of patients who come to the University and non-surgical root canal retreatment is considered as the election of choice in presence of periapical disease. The aim is to evaluate the success rate of non-surgical retreatment performed in one compared to two visit treatment up to 10 years of follow-up. The null hypothesis is that there will be no statistically significant differences in rates of success, when performing root canal non-surgical retreatment in one or two visits.
