Bioceramic sealer root canal obturation: Mandibular molars root canal obturation with bioceramic sealer after non surgical endodontic retreatment and then immediate periapical radiograph will be done to record PAI
resin sealer root canal obturation: non surgical root canal retreatment of mandibular molar teeth will be done using resin based sealer in obturation and periapical radiograph will be taken immediately to record PAI
Study summary
The goal of this clinical trial is to learn if using bioceramic sealers in non surgical single visit endodontic retreatment in patients with endodontic treatment failure and asymptomatic apical periodontitis will work in comparison to other resin sealer which proved efficacy ,and help healing of the periapical lesions and reduce the anticipated postoperative pain , Participants will have root canal retreatment done in a single visit and then follow up will be done in 1, 3 and 6 months to check healing and then after 12 months , also postoperative pain will be monitored through communicating the patients after 24, 28 , 72 hours and the 7 days

Primary outcome measure(s)
Measure the healing of periapical lesions through comparing size of lesion using periapical radiograph and CBCT before and after 1 year follow up — 21 months periapical radiograph and cone beam computed tomography will be taken to measure the size of the lesion and record the PAI and CBCTPAI at baseline then root canal retreatment will be done in single visit using bioceramic sealer in obturation in group A and resin sealer in group B and then periapical radiograph will be taken after 1, 3, 6 , 12 months to record PAI and CBCT at 12 months to record CBCTPAI to evaluate healing through measuring the sizes of periapical lesions , together with clinical record of the patients symptoms after 1, 3 ,6 and 12 months
