Brief summary
In this study the effect of different engine-driven nickel titanium (Ni-Ti) instrumentation systems (OneShape, Revo S and WaveOne) on postoperative dental pain in patients with asymptomatic teeth after a single-appointment root canal retreatment was evaluated.
Detailed description
The aim of this clinical study was to evaluate the effect of different engine-driven nickel titanium (Ni-Ti) instrumentation systems (OneShape, Revo S and WaveOne) on postoperative dental pain in patients with asymptomatic teeth after a single-appointment root canal retreatment. A total of a hundred thirty nine patients with asymptomatic teeth and with no contradictory medical history who were indicated for non-surgical retreatment at the Endodontic Clinic, Faculty of Dentistry, Istanbul Medipol University, between September and December 2016 were included in this study. All of the patients have been recruited from the Istanbul Medipol University Dental Clinics in Istanbul. Out of a hundred thirty nine patients, a total of ninety-nine patients who met the inclusion criteria and agreed to participate was enrolled for the study and were divided into three groups (n=33). Consent was obtained from all study participants before the treatment. After removing previous root canal filling, instrumentation was performed using One Shape, Revo-S, and WaveOne in groups 1, 2, and 3, respectively. All retreatments were performed in a single appointment by one endodontist before permanent coronal restoration. Postoperative pain intensity was assessed at 6, 12, 18, 24, 48, and 72 h; 7 days; and 1 month after the retreatment. The teeth was examined according to for pain intensity, percussion & palpation sensitivity, swelling, analgesic intake and clinical status.
Interventions
DEVICEGroup 1: single file rotary motion
after the previous root canal filling was removed, the shaping procedure of the root canal system was carried out using OneShape Ni-Ti system. the obturation process was completed prior to coronal restoration either with direct or indirect methods
DEVICEGroup 2: multiple file rotary motion
after the previous root canal filling was removed, the shaping procedure of the root canal system was carried out using Revo S Ni-Ti system. the obturation process was completed prior to coronal restoration either with direct or indirect methods
DEVICEGroup 3: single file reciprocal motion
after the previous root canal filling was removed, the shaping procedure of the root canal system was carried out using WaveOne Ni-Ti system. the obturation process was completed prior to coronal restoration either with direct or indirect methods

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in Postoperative Pain after single appointment retreatment at 1 month | 6, 12, 18, 24, 48, and 72 h; 7 days; and 1 month | The primary outcome measure of the study was to assess if different nickel titanium root canal shaping systems influence the intensity and duration of postoperative pain in single-visit non-surgical root canal re-treatments. Postoperative pain was recorded using a four-level verbal rating scale, where 0 indicated no pain, 1 indicated slight pain, 2 indicated moderate pain, and 3 indicated sever pain. the patients were asked to return to the clinic for assessing postoperative pain (tenderness to palpation and percussion) at 24, 48, and 72 h; 7 days; and 1 month after the treatment. One clinician performed all the assessments at 24, 48, and 72 h; 7 days; and 1 month. |
Other
| Measure | Time frame | Description |
|---|---|---|
| unscheduled appointment for emergency intervention | 1 month | the presence or absence of unscheduled appointment for emergency dental intervention was recorded on the chart of the patient as present or absent during the observation time |
| presence of complications | 1 month | the absence or presence of complications (such as swelling or parasthesia) after the intervention was recorded on the chart of the patient as present or absent during the observation time |
