The study design is a double blinded randomized controlled trial and 170 subjects (teeth) , 85 in each of the 2 groups, will be enrolled from the patients at the NUH dental centre endodontic unit. The study aims to assess how the use of TotalFill® bioceramic sealer affects the healing outcome of apical periodontitis compared to a control AH plus®. Conventional root canal treatment will be done during this study. Radiographs will be taken at each study visit during the study for root canal. The preoperative, postoperative and review clinical and radiographic data will be analysed.
