研究目的:

(1)评价PC646对牙周病患者的口腔异味程度、口腔炎症水平及生活质量的影响。 (2)观测患者口腔菌群和粪便菌群变化,从宏基因组学阐述PC646对牙周病患者的影响机理。 (3)综合探究副干酪乳酪杆菌PC646调节轻中度牙周病患者的口臭和口腔炎症的作用及潜在机制。

随机方法(请说明由何人用什么方法产生随机序列):

根据计算机生成的列表生成的随机序列,受试者被随机分配到益生菌组,后生元组或安慰剂组。随机分组是由一名统计学家进行的,他与参与者没有任何接触。参与这项研究的受试者、医生和研究人员在研究完成之前都不知道这些序列。

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

The subjects were randomly assigned to the probiotic, postbiotic, or placebo groups according to a random sequence generated by a computer-generated list. The randomization was performed by a statistician who had no contact with the participants. The subjects, doctors, and researchers involved in the study were unaware of the sequences until the study was completed.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

对受试者、医生均实施盲法,上述人员均不知晓分组实际情况,盲底一式两份,分别由主要研究者和申办方保存。

Blinding:

Subjects and physicians were blinded, and none of the above were aware of the actual status of the subgroups, and the blinded base was kept in duplicate by the principal investigator and the sponsor, respectively.
