简要总结
In cases refractory to initial root canal therapy in which a decision is made to perform nonsurgical retreatment, the patient has the right to know the prognosis of the proposed treatment and clinicians must be able to provide this information based on the best available data. The literature answered this question when the treatment was performed in multiple visits; however, little information exists when single visit root canal retreatment was performed. Therefore, the aim of the present study is to assess the clinical and radiographic outcome of root canal retreatment performed in single visits in endodontic clinics of Dubai Health Authority (DHA).
详细描述
The present study is designed to assess the clinical and radiographic outcome of root canal retreatment performed in single visits in endodontic clinics of Dubai Health Authority (DHA). This is a retrospective study where patients' treatment data will be collected and outcome criteria will be applied blindly.
The sample in this retrospective study will be selected from those patients who have undergone single visit endodontic retreatment at the DHA Endodontics clinics from January 2018, through December 2019. The teeth under investigation will be tracked in the database starting from completion of retreatment for at least 6 months, and the percentages of teeth that were retained or underwent additional procedures such as apical surgery or extraction will be recorded.
The clinical and radiographic assessment at baseline and at recall documented in clinical notes, and all data will be collected using a standardized proforma.
The quality of the existing root canal fillings and the status of the periapical tissues will be determined according to the PAI by 2 calibrated independent observers using the periapical radiographs.
A. Periapical index (PAI) The index is a radiographic method of interpretation that consists of 5 categories, numbered 1-5.
