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.
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)

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| hand files with lateral condensation technique | Experimental | Previously done root canal filling removed by hand files (Hedstrom file,VDW, Munich,Germany ) and shaped with the same files and after instrumentation, all canals were filled by AH Plus sealer (Dentsply De Tray, Costanz, Germany) and lateral condensation technique of gutta-percha. |
|
| Reciproc instrument with lateral condensation technique | Experimental | Previous root canal filling removed by Reciproc instrument (VDW ,Munich, Germany )using Endomotor (VDW, Munich, Germany). After removal, root canal instrumented with the same instrument and obturated using AHPlus sealer with lateral condensation technique of gutta-percha. |
|
| Reciporoc instrument with continuous warmed condensation technique | Experimental | Previous root canal removed by Reciproc instrument using Endomotor, shaped and obturated by AhPlus sealer with continuous gutta-percha technique (Diadent Dia-Duo (Diadent, Chongju, Korea). |

| Root canal treatment | Other | The patient usually takes anaesthesia before treatment and access cavity was prepared on the tooth and root canal removed and instrumented and obturated. However, in the present study, previously done root canal was retreated. Usually no anaesthesia was used because all root canals were done before. So just instrumentation and obturation was done. |
