研究目的: |
主要目的:比较视频宣教与现场教学对口腔门诊就诊牙周炎患者菌斑控制效果的差异,以宣教后3个月Turesky改良Quigley-Hein菌斑指数(TQHI)为主要终点,验证视频宣教的非劣效性(非劣效界值Δ=0.25)。 次要目的:①评估两种宣教模式下改良巴氏刷牙法与竖旋转刷牙法的菌斑清除效果差异;②探索年龄、教育水平、基线菌斑水平对干预效果的修饰效应;③计算视频宣教节约的椅旁时间及增量成本-效果比(ICER);④分析患者口腔健康知-信-行(KAP)得分及满意度的变化。 |

Objectives of Study: |
Primary objective: To compare the plaque control efficacy of video-based OHI versus face-to-face OHI in dental outpatients with periodontitis, using the Turesky modification of the Quigley-Hein Plaque Index (TQHI) at 3 months post-instruction as the primary endpoint, with a non-inferiority margin of Δ = 0.25. Secondary objectives: (1) To evaluate differences in plaque removal between Modified Bass and Roll techniques under each delivery mode; (2) To explore effect modification by age, education level, and baseline plaque severity; (3) To calculate chairside time savings and the incremental cost-effectiveness ratio (ICER) of video-based OHI; (4) To assess changes in oral health Knowledge-Attitude-Practice (KAP) scores and patient satisfaction. |

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
After the study is completed and the primary results are published, the de‑identified raw dataset will be shared upon reasonable request. It is planned that within 6 months after the publication of the main paper, the de‑identified data will be uploaded to the following platform: the Data Sharing System of the ResMan Clinical Trial Management Public Platform, accessible at: [http://www.medresman.org.cn]. Data sharing period: from 6 to 36 months after the publication of the primary results. Access method: after the Data Management Committee reviews the applicant’s reasonable purpose, a data use agreement will be signed, and the de‑identified dataset along with the data dictionary will be provided. |

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)病例记录表(CRF): 本研究使用结构化电子病例记录表(eCRF),内容包括:①受试者人口学信息(年龄、性别、教育水平、吸烟史等);②口腔检查记录(TQHI、MPI评分,菌斑染色面积百分比);③口内照片记录表;④KAP问卷得分;⑤满意度评分;⑥刷牙依从性记录;⑦不良事件记录。所有CRF表单经课题组讨论定稿后导入EDC系统。 (二)电子数据采集和管理系统(EDC): 采用 ResMan EDC电子数据采集系统(网址:http://www.medresman.org.cn) 数据管理措施: 双人独立录入,系统自动进行逻辑核查与范围核查; 数据修改留有审计痕迹(audit trail),所有操作可追溯; 角色权限管理:检查者仅可录入结局数据,不可查看分组信息;研究助理录入分组及随访管理信息; 数据加密传输与存储,定期云端备份; 数据锁定:末例受试者完成末次随访后进行数据清理、质疑解答,确认无误后锁定数据库,锁定后不可修改。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1.Case Report Form (CRF): This study used a structured electronic Case Report Form (eCRF), which includes the following components: Participant demographic information (age, gender, education level, smoking history, etc.); Oral examination records (TQHI, MPI scores, plaque-stained area percentage); Intraoral photo record form; KAP questionnaire scores; Satisfaction rating scores; Toothbrushing adherence/compliance records; Adverse event records. All CRF forms were finalized through research group discussions before being imported into the Electronic Data Capture (EDC) system. 2.Electronic Data Capture and Management System (EDC): The ResMan Electronic Data Capture (EDC) system was used (Website: http://www.medresman.org.cn). Data Management Measures: Dual Independent Data Entry: Data was entered independently by two individuals, with the system performing automatic logical checks and range checks. Audit Trail for Data Modifications: All data modifications leave an audit trail, making all operations traceable. Role-based Access Control: Examiners could only enter outcome data and were prohibited from viewing group allocation information; research assistants entered group assignment and follow-up management information. Encrypted Data Transmission and Storage: Data was transmitted and stored with encryption, and regular cloud backups were performed. Database Locking: After the last participant completed the final follow-up, data cleaning and query resolution were conducted. Once verified and confirmed as correct, the database was locked, after which no modifications were possible. |
