About this study

Official title: Effects of Irrigation Activation on Clinical Outcomes of Root Canal Treatment in Posterior Teeth With Chronic Apical Periodontitis

This study evaluates postoperative pain and radiographic healing of asymptomatic posterior teeth with chronic apical periodontitis following root-canal treatment performed using different methods of irrigation activation.

Read the detailed description

Aim: To evaluate postoperative pain and radiographic healing of asymptomatic posterior teeth with chronic apical periodontitis following root-canal treatment performed using different methods of irrigation activation.

Methodology: In this prospective clinical trial, root-canal treatment was performed on 162 posterior teeth with chronic apical periodontitis. After routine canal preparation, patients were assigned to either a control group treated using conventional needle irrigation (CNI) without activation or to one of 3 treatment groups, each of which was treated using a different activation protocol during the final irrigation [manual dynamic irrigation (MDI), passive ultrasonic irrigation (PUI), sonic irrigation (SI)]. All treatment was completed in a single visit. Patients provided self-assessments of the severity of postoperative pain at 24h, 48h and 7 days using a modified 4-step visual analogue scale (VAS). Patients were recalled at 12 months for clinical and radiographic examinations. Periodontal healing was evaluated using a periapical index (PAI), with scores of 1 or 2 considered to represent treatment success and scores of 3, 4, or 5 to represent treatment failure. Data were analyzed using one-way ANOVA and Kruskal-Wallis tests, with differences of P < 0.05 considered statistically significant.

Study groups in NCT03990584
Study groupRoleWhat they receive
three irrigation activation methodsExperimentalManual dynamic irrigation was performed using a well-fitting gutta-percha cone inserted to WL with in-and-out vertical strokes of 5 mm at a rate of approximately 100 strokes per minute in order to hydrodynamically displace the irrigant. Passive ultrasonic irrigation was performed using a non-cutting size 25 file attached to a piezoelectric ultrasonic unit. Sonic irrigation was performed using an EndoActivator sonic handpiece (Dentsply Tulsa Dental Specialties, Tulsa, OK, USA). A suitable-size activator tip was selected and loosely placed at 2 mm from working length, and the device was operated at 10,000 cycles/min using a pumping action to move the tip to produce vertical strokes of 2-3 mm.
Receives: Procedure: three irrigation activation methods
Conventional needle irrigation (control)Active comparatorConventional needle irrigation was performed with short, in-and-out vertical strokes of 2-3 mm at a rate of approximately 100 strokes per minute.
Receives: Procedure: conventional needle irrigation

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. change from baseline postoperative pain at 1 week

    Pain was measured using a modified visual analogue scale (VAS) with 4 levels, as follows: 1, no pain; 2, slight pain (mild discomfort, no treatment needed); 3, moderate pain (pain required analgesics for relief); 4, severe pain (pain and/or swelling not relieved by simple analgesics and required unscheduled visit). Patients were provided forms and asked to record preoperative pain as well as pain at 24 hours, 48 hours and 1 week postoperatively, and to note down the number of analgesics taken. Patients returned their completed forms at their 1-week follow-up visits.

    Measured: 24 hours, 48 hours and 1 week postoperatively

  2. change from baseline periapical index at 1 year

    Periapical tissue was evaluated using a 5-point periapical index (PAI) (Ørstavik et al. 1986) and scored as follows: 1: Normal periapical structures; 2: Small changes in bone structures; 3: Changes in bone structure with some mineral loss; 4: Periodontitis with well-defined radiolucent area; 5: Severe periodontitis with exacerbating features. If scores varied among roots in the same tooth, the highest score was recorded for that tooth. Similarly, if scores varied between observers for the same tooth, the higher score was recorded.

    Treatment was considered successful if the patient had no discomfort, no percussion/palpation pain, no sinus tract, no mobility or associated soft-tissue swelling, and a PAI score of ≤ 2. Treatment was considered a failure if the patient could not perform normal masticatory functions, experienced discomfort and percussive pain upon examination, and/or had a PAI score of ≥ 3 .

    Measured: Clinical and radiographic examinations were performed on the 1 day of treatment,1 day after treatment and 1 year after treatment.
