Intervention model description: Conventional root canal treatment was perfomed to 45 patients who had been done unacceptable root canal treatment (such as short root canal filling ) on lower premolar or molar teeth before. The patents were healthy and did not take any antibiotics or any medication .
Primary purpose: TREATMENT

Brief summary: Objectives: The aim of this study was to assess postoperative pain in prospective randomized clinical trial comparing Reciproc or hand instrument and also different obturation techniques in one visit of endodontic retreatment.

Conventional root canal treatment was done to 45 patients who needed retreatment. All instruments used in this study are routinely used instrument in endodontic therapy. After completed root canal treatment, the patients asked the intense of post operative pain.

Detailed description: Materials and metods: The study was included 45 patients (18-65 yrs old) who needed endodontic retreatment in mandibular premolar or molar without any symptoms. The teeth had been randomly assign into 3 groups according to the instrumentation or obturation techniques; hand files with lateral condensation, Reciproc with lateral condensation, or Reciproc with continuous condensation technique. Retreatments had performed in a single visit. Coronal restorations were removed, the gutta-percha were extracted using either Reciproc or hand files. After, biochemical and mechanical praparation, the canals were filled with gutta-percha cones and AH Plus sealer using the lateral condensation or continuous wave of obturation technique. Participants were been asked to rate the incidence and intensity of the postoperative pain on a verbal rating scale 24h, 48h and 72h and 7 days after retreatment. All data were analyzed using (Chi-square test, p=0,05)

Eligibility criteria: Inclusion Criteria:

* patients who had previosly done unacceptable root canal treatment on lower premolar or molar with no pain.

No medication should be taken 10 days before treatment for any reason ( such as corticosteroid, antibiotics or analgesic )

Exclusion Criteria:

* age less than 18 or over 65,pregnancy nonrestorable tooth other than lower molar or premolar tooth with more than 4mm periodontal pocket root with broken instrument or any post
