Assessment of Postoperative Pain Following Root Canal Obturation of Permanent Mature Teeth Using Three Different Obturation Techniques: A Randomized Clinical Trial

purpose: to evaluate the postoperative pain incidence and intensity after three different obturation techniques (Cold lateral condensation technique (CLC), Vibration thermo-dynamic technique (Vibra-Tho) and Injection of thermo-plasticized gutta-percha (Fast Fill device)). Materials and Methods: Thirty patients with non-vital mature maxillary incisors requiring endodontic treatment will be randomly divided into three groups (n=10) according to the obturation technique used: Group I (CLC), Group II (Vibra-Tho) and Group III (Fast Fill device). Postoperative pain levels will be recorded using the visual Analogue Scale (VAS) immediately post operative and at 24 hours, 72 hours, one week and two weeks.

Inclusion Criteria: * patients with single rooted mature permanent teeth * presence of symptomatic or asymptomatic irreversible pulpitis or apical periodontitis * medically free patients Exclusion Criteria: * Teeth with previous root canal treatment teeth with anatomical variations patients who take analgesic or antiinflammatory drugs regularly or just before participation in the study
