研究目的:

本研究的目的是验证内窥镜/激光辅助传统 SRP 对基础治疗后残留牙周袋(PD >= 5 mm的深牙周袋)的临床疗效,并评估牙周内窥镜联合激光辅助 SRP 较单独使用牙周内窥镜或激光辅助 SRP 对残留牙周袋是否有额外的临床获益,以为临床残留牙周袋位点的治疗方案提供选择参考,并提高我省在中重度牙周炎非手术治疗方面的水平。  

Objectives of Study:

The aim of this study is to verify the clinical efficacy of endoscope/laser-assisted conventional Scaling and Root Planing (SRP) for residual periodontal pockets (deep pockets with PD >= 5 mm) persisting after initial therapy. Furthermore, it aims to evaluate whether the combination of periodontal endoscopy with laser-assisted SRP confers additional clinical benefits over using periodontal endoscopy alone or laser-assisted SRP alone for the treatment of these residual pockets. This research will provide a reference for clinical decision-making regarding treatment options for residual periodontal pocket sites and enhance the level of non-surgical management of moderate-to-severe periodontitis in our region

随机方法(请说明由何人用什么方法产生随机序列):

由一位专业的口腔内科医师使用计算机随机数法将纳入研究的患者基线时 PD >= 5 mm 的分属于右上颌、左上颌、左下颌以及右下颌 4 个象限的位点随机分入以下 4 组中任意一 组:传统 SRP 组(SRP 组)、内窥镜辅助传统 SRP 组(ESRP 组)、激光辅助 SRP 组(LSRP 组)和内窥镜联合激光辅助 SRP 组(ELSRP) 组。

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

Patients included in the study, with sites exhibiting baseline PD >= 5 mm located in the four quadrants (maxillary right, maxillary left, mandibular left, and mandibular right), were randomly assigned by a professional periodontist using a computer-generated random number method to one of the following four groups: traditional scaling and root planing (SRP group), endoscope-assisted traditional SRP (ESRP group), laser-assisted SRP (LSRP group), and endoscope combined with laser-assisted SRP (ELSRP group).

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:

本临床研究将采用规范的病例记录表(CRF)与先进的电子数据采集(EDC)系统相结合的方式,确保研究数据的准确性、完整性、可靠性和可溯源性。 1. 病例记录表(CRF) CRF根据研究方案设计,内容涵盖受试者知情同意、基线特征、试验干预、有效性评价、安全性观察(不良事件/严重不良事件)及研究结束等所有关键数据点。研究者将依据源文件(病历、牙周探查表等)及时、准确、完整、规范地填写纸质CRF。所有填写均需使用不可擦除的签字笔,任何数据的修改必须遵循“划改”原则(即保留原始记录清晰可辨,注明修改理由、日期并签名)。 2. 电子数据采集和管理系统(EDC) 本研究将采用ResMan临床研究公共管理平台作为EDC系统。授权的研究者将通过个人专属账号和密码登录ResMan系统,将CRF上的数据录入至电子数据库中并进行初步审核。数据管理员通过EDC系统对录入的数据进行核查,并发出数据质疑。整个质疑-回复-关闭的流程均在系统内留有完整记录。在所有数据质疑被妥善解决、数据库经过最终清理和审核后,由主要研究者(PI)和数据管理员共同确认后,对研究数据库进行锁定。数据库锁定后,任何更改均需经过严格的审批程序并记录在案。

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

This clinical study will employ a combination of standardized Case Report Forms (CRFs) and an advanced Electronic Data Capture (EDC) system to ensure the accuracy, integrity, reliability, and traceability of the study data. 1. Case Report Form (CRF) The CRF is designed based on the study protocol and covers all key data points, including subject informed consent, baseline characteristics, trial interventions, efficacy evaluations, safety observations (adverse events/serious adverse events), and study completion. Investigators will complete the paper CRFs promptly, accurately, completely, and legibly based on source documents (e.g., medical records, periodontal charting forms). All entries must be made using a non-erasable pen. Any data modifications must adhere to the "strike-through" principle (i.e., the original entry remains legible, with the reason for the change, date, and signature noted). 2. Electronic Data Capture (EDC) System This study will utilize the ResMan clinical research public management platform as the EDC system. Authorized investigators will access the ResMan system via unique personal credentials to enter data from the CRFs into the electronic database and perform an initial review. Data managers will verify the entered data through the EDC system and issue data queries. The entire process of query issuance, response, and resolution is fully documented within the system. Once all data queries are satisfactorily resolved and the database undergoes final cleaning and review, the study database will be locked following joint confirmation by the Principal Investigator (PI) and the data manager. After database lock, any changes require a formal change control procedure and must be documented.
