随机方法(请说明由何人用什么方法产生随机序列): |
由沈玥含医生将所有受试者采用随机区组化法分组。先根据入组顺序进行分层,6人一层,然后利用随机抽取信封的方式确定每位患者的术式,最终将患者分为三组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
All participants will be assigned to groups using the randomized block design by Dr. Shen Yuehan. First, participants will be stratified according to the enrollment sequence, with 6 participants per block. Subsequently, the surgical procedure for each patient will be determined by random envelope selection, and finally, the patients will be divided into three groups. |

盲法: |
由于不同手术方式在操作层面具有明显差异,无法对术者与患者实施盲法。为降低潜在偏倚,由同一名高级职称牙周专科医师负责手术操作及术后2周内愈合指数评估;但由另一名独立评审者盲法评估术前基线检查和术后3个月及后期指标(评审者对治疗分组未知)。 |
|
Blinding: |
Due to significant differences in the operational procedures of different surgical methods, blinding of the surgeon and patients was not feasible. To reduce potential bias, a single periodontal specialist with senior professional title was responsible for the surgical operations and the assessment of the healing index within 2 weeks postoperatively. However, preoperative baseline examinations and postoperative indicators at 3 months and later were evaluated by an independent reviewer in a blinded manner (the reviewer was unaware of the treatment groups). |
