Introduction: Traditionally necrotic permanent teeth are managed through the conventional procedures of root canal treatment which is known to weaken the remaining tooth structure. Regenerative Endodontic Procedures so have emerged as an alternative to the conventional technique
Aim of the study: The aim of the present study was to compare the post-operative pain intensity following non-surgical root canal treatment and revascularization procedures in mature necrotic teeth.
Materials and methods: Twenty-four adult participants with 30 necrotic mature maxillary anterior teeth were randomly divided into two groups according to the treatment modality; control group: non-surgical root canal treatment; Intervention group: Blood clot revascularization technique. At the first visit in the two groups, all patients recorded their pain level preoperatively using a numerical rating scale (NRS). Mechanical preparation was performed with the ProTaper Universal Ni Ti system up to #F4 file. Double antibiotic paste (DAP) was prepared and injected and the cavity was temporarily sealed. At the second visit, three weeks later, the patients were assigned according to the randomization. The degree of spontaneous postoperative pain was measured using NRS after 6, 12, 24, and 48 hours.
Results: Independent t -test between both groups; showed a highly significance difference, p value<0.05 at 6, 12, and 24 hours postoperatively while in the 48 hours there was no significant difference between both groups, p value >0.05.
