研究目的:

第三磨牙相关第二磨牙牙根外吸收发病率较高,目前绝大多数研究聚焦于导致第二磨牙牙根外吸收的危险因素分析,但对于第三磨牙拔除后第二磨牙的预后以及提升预后的干预措施等研究报道较少,因此本课题拟观察sticky bone 充填拔牙窝在第三磨牙拔除后第二磨牙牙根外吸收的预后情况,以便为临床工作提供一定的参考。  

Objectives of Study:

The incidence rate of external root resorption (ERR) of the second molars which is related to the third molars is high. At present, most studies focus on the analysis of risk factors leading to ERR of the second molars. But there are few reports on the prognosis of the second molars after the extraction of the third molars and the interventions to improve the prognosis. Therefore, this study intends to observe the prognosis of ERR of the second molars after the extraction of the third molars with sticky bone filling, which may provide some reference for clinical work

随机方法(请说明由何人用什么方法产生随机序列):

本研究由独立统计师通过计算机生成随机序列,并密封保存,入组时通过中央系统实时分配

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

This study utilized a computer-generated randomization sequence prepared by an independent statistician, which was securely stored with access restricted until enrollment. Real-time treatment allocation was implemented through a centralized interactive response system (IRS) to ensure allocation concealment.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

本研究采用 “开放标签设计结合盲态数据分析”:医患双方知晓分组(试验组/对照组),但数据采集与分析阶段对研究人员设盲。原始数据中组别标记为“A组/B组”,统计分析由独立团队在盲态下完成。揭盲于最终分析前由第三方统计师统一执行,核对编码与真实分组后生成结果报告,同时进行揭盲后敏感性分析验证结论一致性。

Blinding:

This study employs an "open-label design coupled with blinded data analysis": both clinicians and patients are aware of the treatment assignment (intervention/control), but researchers involved in data collection and analysis remain blinded. Original datasets label groups as "Group A/Group B." Statistical analyses are performed by an independent team under blinded conditions. Centralized unblinding is executed by a third-party statistician prior to final analysis, who verifies coding against actual allocations to generate outcome reports, accompanied by post-unblinding sensitivity analyses to validate result consistency.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

病例数据的采集方式为:利用病例记录表(CRF)。负责临床试验数据管理的人员已经过GCP、相关SOP及数据管理的专业培训CRF的设计保证收集试验方案里要求的所有临床数据。在临床试验完成后,拟对试验过程中的文档进行存档,包括临床试验数据、数据管理计划书等。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

The method for collecting case data is through the utilization of Case Report Forms (CRFs). Personnel responsible for clinical trial data management have undergone professional training in Good Clinical Practice (GCP), relevant Standard Operating Procedures (SOPs), and data management. The design of the CRF ensures the collection of all clinical data required by the trial protocol. Upon completion of the clinical trial, it is planned to archive the documents generated during the trial process, including clinical trial data, data management plans, and other relevant materials.
