简要总结
Sixty-three mandibular molars with vital pulp, symptomatic acute pain, and a Numerical Rating Scale (NRS) score of 7 or higher-requiring emergency treatment-were randomly allocated into three groups according to the preparation systems to be used: conventional manual instrumentation technique with hand files, reciprocating motion technique with WaveOne Gold files, and rotary motion technique with ProTaper Ultimate files.
In the first session, patients received emergency treatment with one of the three file systems, and seven days later, root canal treatments were completed using the same system within each patient group. Preoperative pain scores of patients presenting to our clinic with acute pain were recorded using the Numerical Rating Scale (NRS).
During the emergency root canal treatment session, the first group was instrumented with hand files, the second group with WaveOne Gold files, and the third group with ProTaper Ultimate files, and the emergency treatment session was completed. Shaping times were measured during the procedures.
Following the emergency session, patients were instructed to record their postoperative pain at the 6th hour, 12th hour, and on the 1st, 2nd, 3rd, 4th, 5th, 6th, and 7th days using the provided NRS.
One week after the emergency treatment session, root canal obturation was performed using each system's own gutta-percha and Bioceramic root canal sealer. Clinical and radiographic follow-ups were carried out at 6 and 12 months.
详细描述
• This randomized clinical study was conducted to evaluate and compare the effects of the conventional step-back technique with hand files, the reciprocal technique with WaveOne Gold files, and the rotary technique with ProTaper Ultimate files on the frequency and intensity of pain before and after emergency treatment, as well as on clinical and radiological outcomes in symptomatic and acutely painful vital molars during root canal treatment.
Sixty-three symptomatic mandibular molars with vital pulp were randomly allocated into three groups according to the preparation system used: Hand files, WaveOne Gold, and ProTaper Ultimate. The file systems assigned to each group were used for root canal preparation in all cases.
In the rotary and reciprocating file groups, obturation was performed with their own gutta-percha using the single cone technique with Bioceramic sealer and in the conventional hand file group root canal obturation was performed with cold lateral compaction method.

研究组 & 干预措施
Conventional Manuel Instrumentation Technique Group
Root canals were prepared with hand files. Irrigation was performed with 10 mL of NaOCl, followed by 5 mL of 17% ethylenediaminetetraacetic acid (EDTA). Temporary coronal restoration was completed with glass ionomer cement. For this group, 72 hours after the completion of root canal preparation in the emergency intervention session, calcium hydroxide was applied to the root canals for 7 days, and the teeth were obturated using a bioceramic root canal sealer with the system-specific gutta-percha and obturation methods recommended by the manufacturers.

Reciprocating Motion Technique Group
Root canals were prepared with WaveOne Gold instruments and an X-Smart Plus (Dentsply Maillefer, Switzerland) endodontic motor. Irrigation was performed with 10 mL of NaOCl, followed by 5 mL of 17% ethylenediaminetetraacetic acid (EDTA). Temporary coronal restoration was completed with glass ionomer cement. For this group, 72 hours after the completion of root canal preparation in the emergency intervention session, calcium hydroxide was applied to the root canals for 7 days, and the teeth were obturated using a bioceramic root canal sealer with the system-specific gutta-percha and obturation methods recommended by the manufacturers.

结局指标
主要结局
The incidence and intensity of post-obturation pain
时间窗: up to 30-day
Post-obturation pain up to 30 days after root canal treatment was measured with Numerical Rating Scale. The Numerical Rating Scale is a pain measurement scale that encompasses the following grades: 0 no pain, 1-3 mild pain, 4-6 moderate pain, 7-10 severe pain.
次要结局
- Clinical and radiographical success(Up to 1 year follow up)
