Aim The aim of this study is to evaluate the post-operative pain after one week and the success rate of different endodontic obturation methods after one year follow-up. 

Materials and methods Forty teeth were selected and randomly assigned to 4 groups. In group A teeth were treated using warm vertical compaction with gutta-percha and zinc oxide eugenol sealer, in group B the single cone technique was performed in association with a bioceramic sealer, in group C obturation was performed with thermoplastic guttapercha injection with bioceramic sealer (bioconeless technique), in group D teeth were treated with thermoplasticized gutta-percha injection with zinc-oxide-eugenol sealer (coneless technique). At the end of each procedure, a periapical radiograph was taken to assess the filling and a form was given to each patient to record analgesic intake.  

Results After 1 week, in group A the analgesic intake was 3.1±1.9 and 10/10 patients referred pain to percussion; in group B the analgesic intake was 1±1.5; with 2/10 patients referring pain to percussion; in group C analgesic intake was 0.8±0.9 with 1/10 patients having pain to percussion; in group D the analgesic intake was 3±1.2 with 9/10 patients with pain to percussion. The data reported a significantly higher value of analgesic intake for the warm vertical compaction technique versus the single cone (p<0.05) and bioconeless (p<0.05); moreover, the coneless technique was associated with significantly higher analgesic intake versus single cone (p<0.05) and bioconeless (p<0.05) techniques. At the 1 year follow up the success rate was 100% for all groups.

Conclusion The results of this study show less post-operative pain and less analgesic intake associated with bioceramic sealer compared to the zinc oxide eugenol-based sealer.
