简要总结
The aim of this study is to evaluate the impact of anterior disc displacement with reduction (ADDR) on postoperative pain following root canal treatment in patients diagnosed with symptomatic apical periodontitis.
详细描述
This prospective clinical study included individuals diagnosed with symptomatic apical periodontitis who had a vital mandibular molar tooth and were diagnosed with anterior disc displacement with reduction (ADDR) according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) (n = 45), as well as individuals without any temporomandibular joint pathology (n = 45). Following patient dropouts, a total of 70 patients with complete and eligible data were included in the final analysis, with 35 participants in each group.
All root canal treatments were performed by the same clinician using a standardized treatment protocol. Postoperative pain intensity was assessed using the Numeric Rating Scale at 6 and 12 hours and at 1, 2, 3, 5, and 7 days after treatment. In addition, joint sounds, joint pain, and maximum mouth opening were recorded in the preoperative period and at the 7-day postoperative follow-up, and their associations with postoperative pain were analyzed.
The findings of this study provide insight into the relationship between temporomandibular joint disorders and endodontic postoperative pain and may contribute to improved clinical understanding.

盲法说明
An oral diagnosis and radiology specialist with more than 10 years of clinical experience evaluated the patients' endodontic treatment needs and performed the temporomandibular joint examination. Patients diagnosed with anterior disc displacement with reduction according to the Diagnostic Criteria for Temporomandibular Disorders were assigned to the experimental group, while individuals without temporomandibular joint disorders constituted the control group.
At this stage, both the participants and the clinician performing the root canal treatments were blinded to the temporomandibular joint status of the patients (double-blind). Group allocation was concealed until completion of the data analysis, resulting in a triple-blind study design.

结局指标
主要结局
Postoperative pain intensity
时间窗: 6, 12 hours 1, 2, 3, 5 and 7 days postoperatively
To evaluate postoperative pain, each patient was provided with a pain diary after root canal treatment and was instructed to record pain intensity using the Numeric Rating Scale (NRS). Detailed instructions on how to use the NRS were given to all participants. Pain intensity was recorded at 6, 12, 24, 48, and 72 hours and at 5 and 7 days after treatment. Patients were prescribed 400 mg ibuprofen for use only in cases of severe pain. Data from patients who used analgesics during the follow-up period were excluded from the analysis.
次要结局
- Maximum mouth opening(Baseline and 7 days postoperatively)
- Temporomandibular joint pain and percussion sensitivity(Baseline and 7 days postoperatively)
