Research summary
The current gold standard for detecting periapical pathology is the periapical radiograph (PA). However, PA has a limited diagnostic ability.
It has been suggested that due to the higher detection of periapical lesions before and after root canal treatment (RCT) with cone beam computed tomography (CBCT), the success of RCT should be reevaluated with long-term follow-up studies.
Several studies have compared the outcome of non-surgical RCT with PA and CBCT; they all had a higher incidence of failure with CBCT than with PA.This longitudinal study aims to evaluate the success of surgical root canal treatment. This will be carried out at Guy's Hospital as a part of the routine dental treatment at the endodontic postgraduate unit. Potential participants will be given a written information sheet and sufficient time to consider participation. Fully informed written consent will be obtained if they are interested in participation.
After providing consent, all participants will receive PA radiograph and CBCT scans which are part of standard care in root canal treatment. Then, a clinical assessment will be carried out for the tooth needing treatment which is routinely done before treatment.
Treatment will be carried out by MclinDent postgraduate or PhD students supervised by their assigned clinical supervisor. It is a standard of care for students to undertake this type of treatment.
After one year and two years, all patients will be contacted for follow up appointments. Paired clinical and radiographic examination (PA and CBCT) will be carried out, matching the baseline measures. Healing will be evaluated radiographically and clinically. The tooth of interest will be examined, the restoration will be evaluated, and the scans will be checked for radiographic healing. This follow up procedure is a standard of care and it is beneficial for the patients as this would aid in the early management of any recurrent infection.
