Outcome Measures

Primary Outcomes (9)

  • Pain level comparison after the application of three different root canal medicaments in root canal : VAS (Visual Analogue Scale) at 6th hours.

    Based on the VAS (Visual Analogue Scale), the pain levels of the patients were assessed. The scale consisted of a 100-mm-long line divided into 10 equal intervals from 0 (no pain) to 100 (very severe pain). Every patient was asked to mark his or her perceived postoperative pain level on the line.

    6 th hours

  • Pain level comparison after the application of three different root canal medicaments in root canal : VAS (Visual Analogue Scale) at 12 th hours.

    Based on the VAS (Visual Analogue Scale), the pain levels of the patients were assessed. The scale consisted of a 100-mm-long line divided into 10 equal intervals from 0 (no pain) to 100 (very severe pain). Every patient was asked to mark his or her perceived postoperative pain level on the line.

    12 th hour

  • Pain level comparison after the application of three different root canal medicaments in root canal : VAS (Visual Analogue Scale) at 24th hours.

    Based on the VAS (Visual Analogue Scale), the pain levels of the patients were assessed. The scale consisted of a 100-mm-long line divided into 10 equal intervals from 0 (no pain) to 100 (very severe pain). Every patient was asked to mark his or her perceived postoperative pain level on the line.

    24 th hour

  • Pain level comparison after the application of three different root canal medicaments in root canal : VAS (Visual Analogue Scale) at 2nd days.

    Based on the VAS (Visual Analogue Scale), the pain levels of the patients were assessed. The scale consisted of a 100-mm-long line divided into 10 equal intervals from 0 (no pain) to 100 (very severe pain). Every patient was asked to mark his or her perceived postoperative pain level on the line.

    2nd days

  • Pain level comparison after the application of three different root canal medicaments in root canal : VAS (Visual Analogue Scale) at 3th days.

    Based on the VAS (Visual Analogue Scale), the pain levels of the patients were assessed. The scale consisted of a 100-mm-long line divided into 10 equal intervals from 0 (no pain) to 100 (very severe pain). Every patient was asked to mark his or her perceived postoperative pain level on the line.

    3th days

  • Pain level comparison after the application of three different root canal medicaments in root canal : VAS (Visual Analogue Scale) at 4th days.

    Based on the VAS (Visual Analogue Scale), the pain levels of the patients were assessed. The scale consisted of a 100-mm-long line divided into 10 equal intervals from 0 (no pain) to 100 (very severe pain). Every patient was asked to mark his or her perceived postoperative pain level on the line.

    4th days

  • Pain level comparison after the application of three different root canal medicaments in root canal : VAS (Visual Analogue Scale) at 5th days.

    Based on the VAS (Visual Analogue Scale), the pain levels of the patients were assessed. The scale consisted of a 100-mm-long line divided into 10 equal intervals from 0 (no pain) to 100 (very severe pain). Every patient was asked to mark his or her perceived postoperative pain level on the line.

    5th days

  • Pain level comparison after the application of three different root canal medicaments in root canal : VAS (Visual Analogue Scale) at 6th days.

    Based on the VAS (Visual Analogue Scale), the pain levels of the patients were assessed. The scale consisted of a 100-mm-long line divided into 10 equal intervals from 0 (no pain) to 100 (very severe pain). Every patient was asked to mark his or her perceived postoperative pain level on the line.

    6th days

  • Pain level comparison after the application of three different root canal medicaments in root canal : VAS (Visual Analogue Scale) at 7th days.

    Based on the VAS (Visual Analogue Scale), the pain levels of the patients were assessed. The scale consisted of a 100-mm-long line divided into 10 equal intervals from 0 (no pain) to 100 (very severe pain). Every patient was asked to mark his or her perceived postoperative pain level on the line.

Interventions

Two different root canal medicaments and their combination were placed into the root canals following the removal of previous root canal fillings and re-instrumentation. Afterward, postoperative pain scores were recorded at 6 and 12 hours and at 1, 2, 3, 4, 5, 6, and 7 days using the visual analog scale (VAS). Sensitivity on percussion, spontaneous pain, swelling, and antibiotic and analgesic requirements of the patients were married during clinical examinations performed postoperatively after 2 and 7 days.

You may qualify if:

  • Patients between 20 - 65 years of ages
  • Patients who agree to participate this study
  • Not taking analgesic or antibiotics in the last week
  • Single root and single-canal incisor, canine, premolar teeth that have been treated only once before
  • Teeth with previous endodontic treatment but with insufficient root canal filling on radiographic examination
  • Teeth with periapical lesions and at least 2 years since the previous treatment, although root canal filling seems sufficient
  • Periapical radiolucency, teeth with increased or unchanged according to pre-treatment radiography (if available)
  • Teeth are asymptomatic
  • Patients who had good oral hygiene

You may not qualify if:

  • Pregnant patients and patients in lactation period
  • Having used corticosteroids in the last 6 months
  • Individuals with systemic diseases (endocarditis, immune system diseases,etc.) requiring antibiotic prophylaxis
  • Having received immunosuppressive therapy within the last week
  • Patients who had systemic or allergic sensitivty for the NSAIDs and local ananesthetics
  • The presence of advanced periodontal disease (probing depth \> 4 mm)
  • The presence of a foreign body in the root canal that prevents entry (broken file, post, etc.)
  • Fracture or crack in the root
  • Teeth that cannot reach the working length due to calcification in the root canal and step formation
  • Teeth that cannot be restored due to excessive loss of material in the coronal structure
  • The presence of more than one adjacent tooth requiring endodontic treatment that may cause reflected pain in the same patient.
  • Teeth that develop any complications ( breakage of endodontic file, perforation, inability to determine the working length with the apex finder) during the removal of the canal filling material.
