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: |
在数据收集内容上,将全面采集术前、术中及术后全流程信息:术前收集患者性别、年龄、全身病史(糖尿病、高血压、吸烟史、骨质疏松等)、口腔专科检查结果、CBCT 影像学测量数(根尖病灶大小、牙根形态、根尖孔发育状态、牙槽骨量等);术中记录手术方式、微创拔牙操作细节、牙齿离体干燥时间、牙周膜保护处理方式、根管治疗及根尖倒充填材料类型、生物陶瓷材料使用情况、供体牙与受体窝匹配度等关键参数;术后按固定时间节点(术后 2 周、1 个月、3 个月、6 个月、1 年及以上)随访,收集临床检查指标(牙齿松动度、叩痛、牙周袋深度、牙龈愈合情况)、影像学复查结果及牙根吸收、骨性粘连、感染等并发症发生情况,形成完整的纵向观察数据。在数据收集流程上,由经过统一培训的专职研究人员负责病例筛选与数据记录,使用标准化病例报告表(CRF)进行填写,确保记录规范、信息无遗漏。影像学资料以 DICOM 格式统一存储,临床照片及复查影像按患者编号分类归档,避免资料混淆。 在数据管理与质量控制上,采用双人双独立录入方式将数据录入专用电子数据管理系统,录入完成后进行交叉核对,对不一致数据及时溯源修正。研究期间定期开展数据核查与逻辑校验,及时发现并纠正缺失、错误及异常数据。所有研究数据均进行加密存储与定期云端备份,严格保护患者隐私信息,去除个人身份标识,仅保留研究编号用于数据分析。整个数据收集与管理过程遵循临床研究相关规范,确保数据质量满足统计分析要求,为研究结果的可靠性提供支撑。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
In terms of data collection content, full-process information before, during and after surgery will be comprehensively collected. Preoperatively, patient gender, age, systemic medical history (diabetes, hypertension, smoking history, osteoporosis, etc.), results of specialized oral examinations, and CBCT radiographic measurements (size of periapical lesion, root morphology, developmental status of apical foramen, alveolar bone mass, etc.) are collected. Intraoperatively, key parameters are recorded, including surgical approach, details of minimally invasive tooth extraction, extraoral drying time of extracted teeth, periodontal ligament protection methods, types of root canal therapy and retrograde filling materials, application of bioceramic materials, and matching degree between donor tooth and recipient alveolar socket. Postoperative follow-up is conducted at fixed time points (2 weeks, 1 month, 3 months, 6 months, 1 year and above after surgery). Collected data include clinical examination indicators (tooth mobility, percussion pain, periodontal pocket depth, gingival healing status), radiographic re-examination results, and the incidence of complications such as root resorption, ankylosis and infection, so as to establish complete longitudinal observational data.In terms of data collection procedures, case screening and data recording are performed by specially assigned researchers with unified professional training. Standardized Case Report Forms (CRF) are adopted for filling in to ensure standardized recording and complete information integrity. Radiographic data are uniformly stored in DICOM format, and clinical photographs as well as re-examination images are archived by patient number to avoid data confusion.In terms of data management and quality control, a double-entry independent recording method is adopted to import data into a dedicated electronic data management system. Cross-verification is conducted after data entry, and inconsistent data are traced back and corrected in a timely manner. Regular data inspection and logical verification are carried out during the study to identify and rectify missing, erroneous and abnormal data promptly. All research data are encrypted for storage and regularly backed up on the cloud. Patient privacy is strictly protected by removing personal identification information, and only research numbers are retained for data analysis. The entire process of data collection and management complies with relevant clinical research specifications, ensuring that data quality meets the requirements for statistical analysis and providing support for the reliability of research results. |
