Brief Summary

The aim of this study is to evaluate the effects of pre-treatment and procedural factors on survival and success rates in teeth that underwent non-surgical root canal retreatment at Trakya University, Faculty of Dentistry between 2015-2017.

Pre-treatment factors examined:

• Age
• Gender
• Presence and size of periapical lesion
• Quality of root canal obturation

Factors examined during treatment:

• Type of restoration
• Status of restoration at recall

The null hypothesis was that these factors have no effect on survival and success rate.

Detailed Description

Patients with teeth that had undergone non-surgical recurrent root canal treatment at Trakya University, Faculty of Dentistry between 2015-2017 were invited for examination. Clinical and radiological examinations were performed on patients who agreed to participate in the study. No additional interventional procedures were performed. As a result of radiological and clinical examinations, whether the tooth was in the mouth, its clinical and radiological health, current clinical symptoms, etc. were determined.
