指标中文名:

根尖周组织影像改善率

指标类型:

次要指标

Outcome:

Improvement rate of periapical tissue imaging

Type:

Secondary indicator

测量时间点:

根管充填后3个月

测量方法:

根尖周组织影像改善采用根尖周指数(periapical index, PAI)来评价。PAI是代表根尖周病变不同组织学表现阶段的X线片分类。根尖周组织影像改善率包括根充后3个月PAI降低的例数和PAI<=2的例数。即: 根尖周组织影像改善率=(PAI降低例数+PAI<=2例数)/总例数*100%。

Measure time point of outcome:

3 months post-obturation

Measure method:

The improvement in periapical tissue imaging was evaluated using the periapical index (PAI). The PAI is a radiographic classification representing different histological stages of periapical pathology. The improvement rate of periapical tissue imaging includes the number of cases with a reduced PAI score and the number of cases with a PAI score <=2 at 3 months post-obturation. The calculation formula is: Improvement rate of periapical tissue imaging = (Number of cases with reduced PAI + Number of

指标中文名:

由研究者告知受试者VAS疼痛量表的使用方法,然后受试者自行在VAS评分表上标记疼痛程度。

Measure time point of outcome:

3 days after root canal irrigation, 10 days after root canal irrigation

Measure method:

The investigator explained how to use the VAS for pain assessment to the participants, who then marked their pain level on the VAS form themselves.

Measure time point of outcome:

On the day of the first root canal treatment

Measure method:

On the day of root canal treatment, the presence of device deficiencies was evaluated by checking the trial device labels for errors and by recording whether any quality issues or malfunctions occurred during the use of the investigational product. The start and end time of any device deficiency, detailed circumstances of its occurrence and management, measures taken regarding the device, whether it led to a SAE, and the outcome of its resolution were documented in detail.

随机方法(请说明由何人用什么方法产生随机序列):

本研究应用中央随机系统(IWRS)进行随机分配,各中心竞争入组,最后一例受试者分配随机号后,由随机号管理员从随机系统中导出随机表,向申办者移交。

Randomization Procedure (please state who generates the random number sequence and by what method):

This study used a central web-based randomization system (IWRS) for random allocation. Enrollment was competitive across all centers. After the last subject was assigned a randomization number, the randomization list was exported from the system by the randomization number administrator and transferred to the sponsor.
