随机方法(请说明由何人用什么方法产生随机序列):

随机化由研究团队中的一名成员执行,由计算机创建两组随机数:无骨壁缺损、颊侧骨壁缺损。随机数字分别装在两组按顺序编号的不透明信封中。拔牙术后检查并测量受试者目标位点颊侧骨壁,根据受试者是否有骨缺损选择合适的信封以确定受试者的分组(试验组或对照组)。观察者不知道受试者的分组情况。

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

Randomization was performed by a member of the study team, and a computer created two sets of random numbers: no bone wall defects, and buccal bone wall defects. The randomized numbers were placed in two sets of sequentially numbered opaque envelopes. The buccal lateral bone wall of the subject's target site was examined and measured after the extraction, and the appropriate envelope was selected to determine the subject's grouping (experimental or control) based on the presence or absence of bone defects. The grouping of the subjects was not known to the observer.

盲法:

本研究为单盲设计,对研究者中的观察者设盲。本研究对评价者阳涛医师设盲,盲底保存在口腔种植科办公室抽屉,上锁,保证评价者接触不到。

Blinding:

This study was a single-blind design and was blinded to the observer in the study. The study was blinded to the evaluator, Dr. Yang Tao, and the blind bottom was kept in the office drawer of the Oral Implantology Department, which was locked to ensure that the evaluator did not have access to it.

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:

临床采集数据将及时、真实、准确、完整的记录在病例报告表内。牙髓染色后的图像将会存储在专用移动硬盘内,硬盘加密保存。主要研究者对数据的真实、完整、准确性负责。本试验设有病例报告表,病例报告表内容与试验方案一致。临床采集数据将及时、真实、准确、完整的记录在病例报告表内。

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

Clinical collection data will be recorded timely, truthfully, accurately and completely in the case report form. Images after endodontic staining will be stored in a dedicated portable hard disk with encrypted hard disk storage. The principal investigator is responsible for the truthfulness, completeness and accuracy of the data. A case report form is available for this trial and the content of the case report form is consistent with the trial protocol. Clinical data will be recorded in a timely, factual, accurate and complete manner in the case report form.
