Brief summary: 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.


Eligibility criteria: Inclusion Criteria:

* Patients that demonstrate understanding of the study and willingness to participate as evidenced by signing the voluntary informed consent and received a signed and dated copy of the informed consent form.
* Understands and is willing to comply with all study procedures and restrictions.
* Not presence of clinically significant and relevant abnormalities of clinical history or oral examination.
* Retreatment cases due to an endodontic failure.
* Diagnosis of apical periodontitis.
* Single or bi-radicular teeth.

Exclusion Criteria:

* General: Patients with systemic diseases, diabetes, immunocompromised and pregnant women, or any clinically significant or relevant oral abnormalities.
* Specific: root resorption, root fractures, impossibility of restoration and cases were secondary root canal treatment is not the treatment of choice.
