简要总结
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.
详细描述
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.

干预措施: radiological and clinical examination (Diagnostic Test)
结局指标
主要结局
Survival rate
时间窗: 78.47 ± 10.48 months after treatment
Survival Rate: Survival was assessed whether the tooth was in the mouth or not. Survival was scored positive if the tooth was in the mouth, regardless of the health status of the tooth in the clinical and radiological examination at the follow-up appointment.
Success rate
时间窗: 78.47 +10.48 months
Success Rate: Scored as successful or unsuccessful according to the following effects according to the clinical and radiological examinations; restoration status, health of the periapical tissues, presence of swelling and/or the sinus tract. Success: The tooth had no clinical signs or symptoms, and the radiographs revealed complete resolution of periapical lesion Failure: The size of the periapical lesion was unchanged or increased or not completely healed, with or without clinical signs or symptoms
