NCT04314908

Brief Summary

The purpose of this randomized clinical trial is to evaluate the incidence of postoperative pain after retreatment after apical enlargement and sonic activation assisted irrigation. The presence of postoperative pain will assess after retreatment cases at 12, 24, 48, 72 hrs and 1 week.

Outcome Measures

Primary Outcomes (1)

  • Change from Baseline in Postoperative Pain after Root Cana Treatment at 1 week: VAS

    The primary outcome measure of the study is to assess if sonic activation assisted irrigation and apical enlargement procedures influence the occurrence of postoperative pain.Postoperative pain was assessed using a well defined Heft-Parker visual analogue scale (VAS) scale. Each patient recorded the pain level on a 100-mm VAS scale experimental basis for revising the graphic rating scale for pain in well-defined categories at 5 time intervals as 12, 24, 48, 72 hours and 1 week after treatment. The VAS scale was divided into 4 categories: No pain or faint pain corresponded to 0 mm. Mild pain was defined as greater than 0 mm and less than or equal to 25 mm. Mild pain included the descriptors of weak and mild pain. Moderate pain was defined as greater than 50 mm and less than 75 mm. Intense pain was defined as equal to or greater than 75 mm. Intense pain included the descriptors of strong, severe, and maximum possible.

    Baseline, 12, 24, 48, 72 hours and 1 week.

Study Arms (4)

Apical enlargement

EXPERIMENTAL

Routine retreatment procedure will be performed at working length according to the apex locator at point "0".

Procedure: Apical enlargement

Apical enlargement + Sonic Activation Assisted Irrigation

EXPERIMENTAL

Routine retreatment procedure will be performed at working length according to the apex locator at point "0" and sonic activation assisted irrigation will be applied.

Procedure: Apical enlargement + Sonic Activation Assisted Irrigation

Non Apical enlargement

EXPERIMENTAL

Routine retreatment procedure will be performed at working length according to the apex locator at 1mm shorter than "0" point.

Procedure: Non Apical enlargement

Non Apical enlargement + Sonic Activation Assisted Irrigation

EXPERIMENTAL

Routine retreatment procedure will be performed at working length according to the apex locator at 1mm shorter than "0" point and sonic activation assisted irrigation will be applied.

Procedure: Non Apical enlargement + Sonic Activation Assisted Irrigation

Interventions

The teeth in this group will be treated according to the guidelines for retreatment in single-session. The filling will remove and cavity will be opened. The working length will be measured using apex locator and the "0" point will be based on. After standard irrigation protocol, root canals will be obturated with gutta percha and root canal sealer. Coronal restoration will complete using composite and/or fully crown if necessary.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients who were healthy volunteers and who have failed teeth required retreatment with periapical index score 3-5 score requiring root canal treatment for first time.
  • Patients who were not included the study who;
  • were pregnant or breast feeding during the duration of the study,
  • have systemic disease, have any pain and/or any facial swelling, abscess,
  • were immunocompromised,
  • were under 18 yrs. and over 65 yrs. age,
  • were taking antibiotics or corticosteroids within previous three days,
  • have multiple teeth that required root canal treatment at the same time period; for eliminating pain referral,
  • have root canals that could not be well-treated with orthograde retreatment.

You may not qualify if:

  • The patients who forgot to fill out the form and took antibiotics and/or analgesics right after the first appointment of the therapy were excluded from the study.
