The Effect of Instrumentation and Obturation on Postoperative Pain in Retreatment

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.

About this study

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)

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

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

Treatment and study plan

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.

Primary outcomes

  1. Post operative pain

    Time frame: 24 hours.

    VRS scale was used to assess the intensity of post operative pain or discomfort( 0: no pain,1:mild pain, no medication (analgegic) is requiered, 2 :moderate pain ,feeling pain but no medication is required, 3: severe pain: feeling pain need to take analgesic

Secondary outcomes

  1. Post operative pain; change is being assessed.

Other outcomes

  1. Post operative pain; change is being assessed.

    Time frame: 72 hours.
