Cross-sectional 

研究目的:

应用锥形束计算机断层扫描(CBCT)测定华南地区人群上颌尖牙至第二磨牙区腭侧咀嚼黏膜厚度及腭大孔的分布位置,并探究其是否与年龄、性别、腭弓形态、错颌畸形类型等因素是否具有相关性。  

Objectives of Study:

To determine the thickness of the palatal masticatory mucosa and the location of the greater palatine foramen in the region from maxillary canine to the second molar in a southern Chinese population using cone-beam computed tomography (CBCT), and to explore the correlation between the thickness of the palatal mucosa and age, gender, palatal arch morphology, and malocclusion type.

测量指标:

Outcomes:

指标中文名:

腭大孔位置

指标类型:

主要指标

Outcome:

Location of the greater palatine foramen

Type:

Primary indicator

测量时间点:

测量方法:

在水平面、冠状面和矢状面中标记患者的腭大孔位置。调整水平面至邻接面处,以上颌第一磨牙中央、远中面,上颌第二磨牙中央、远中面为基准,作四条切线,将区域分为 a、b、c、d、e 五部分。继续调整水平面至腭大孔位置,进行区域分类。调整冠状面至腭大孔中心,测量腭大孔中心到腭中缝和牙槽嵴的距离,并计算其比值 R’=W2/W1。

Measure time point of outcome:

Measure method:

The position of the greater palatine foramen of the patient was marked in the horizontal, coronal, and sagittal planes. Adjust the horizontal plane to the adjacent surface, Four tangent lines were made on the central and distal surfaces of the upper first molar and the central and distal surfaces of the upper second molar. The region was divided into five parts: a, b, c, d, and e. Continue to adjust the horizontal plane to the position of the greater palatine foramen for regional classification.

指标中文名:

腭侧黏膜厚度

指标类型:

主要指标

Outcome:

Thickness of the palatal mucosa

Type:

Primary indicator

测量时间点:

测量方法:

在 CBCT 图像上,在每颗牙齿的腭侧中部区域的冠状图像上测量腭黏膜厚度。从 龈缘开始,以相等的 3mm 间隔沿腭黏膜表面标记 3 个点,在每个点绘制一条垂 直于牙槽嵴的线,在标记点处测量上颌尖牙和第二磨牙之间的腭黏膜厚度。

Measure time point of outcome:

Measure method:

On CBCT images, palatal mucosal thickness is measured on coronal images of the mid-palatal region of each tooth. Starting from the gingival margin, three points were marked along the surface of the palatal mucosa at equal 3-mm intervals, and a vertical line was drawn at each point The thickness of the palatal mucosa between the maxillary canine and the second molar was measured at the marked point on the line straight from the alveolar ridge.

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:

(1)数据安全管理 1)数据安全管理 1) 文件保护 工作表保护:锁定除数据录入区域外的所有单元格(如公式、标题行); 密码加密:文件 → 信息 → 保护工作簿 → 用密码加密。 2) 存储与备份 本地存储:Excel 文件保存于硬盘,禁止使用 U 盘或云盘; 备份规则: 每日测量后另存为带日期文件(如 PMT 数据_20231003.xlsx); 每周备份 3) 去标识化要求 删除所有直接标识符(姓名、身份证号、联系方式); (2)质量控制流程 1) 双人录入校验 研究者 A 录入原始数据,研究者 B 使用比较工作表功能核对差异; 2) 异常值筛查 定期人工复核:每周随机抽取 10%记录,对比原始病历/影像报告。 3) 版本控制 禁止直接在原文件上修改,所有变更通过“另存为”生成新版本

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

1) Data security management 1) File protection Worksheet protection: lock all cells except the data entry area (such as formula, title row); Password encryption: File → Information → Protect workbook → Encrypt with password. 2) Storage and backup Local storage: Excel files are saved on the hard disk, U disk or cloud disk is prohibited; Backup rules: Daily measurement is saved as a date file (such as PMT data _20231003.xlsx); Weekly backup 3) De-identification requirements Remove all direct identifiers (name, ID number, contact information); (2) Quality control process 1) Double entry verification Researcher A entered the original data, and researcher B checked the differences using the comparison worksheet function. 2) Abnormal value screening Regular manual review: 10% of records were randomly selected every week to compare the original medical records/imaging reports. 3) Version control It is forbidden to modify the original file directly. All changes are generated by "save as" to create a new version
