随机方法(请说明由何人用什么方法产生随机序列):

本研究采用区组随机化的方式实现入组病例在试验组与对照组之间的随机分配。随机数通过SAS9.4的PLAN过程产生。受试者根据生成的随机数及相应规则按 1:1 随机分配进入试验组或对照组。

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

Block randomization will be used in this study to randomly allocate enrolled subjects to the test group or the control group. The random numbers will be generated from the PLAN procedure by SAS 9.4. Subjects enrolled will be randomly allocated to the test group or the control group according to the generated random numbers with the corresponding rules in a 1:1 ratio.

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:

由于患者对于不同术式的感知存在明显差异,因此本研究在实施过程中并未对参与研究的医生及患者设盲,仅在疗效指标测量时对评估者设盲。具体方法为由不参与检查、治疗、数据分析的人员对参与随机化的每位受试者在基线及不同随访时间点进行临床指标的记录与测量,并将测量结果交给统计师进行数据的统计和分析。

Blinding:

Due to the significant differences in perception of different surgical procedures among patients, neither dentists nor patients will be blinded during the research. Only the evaluators will be blinded when calculating the evaluation indicators. Specifically, a person not involved in the examination, treatment, and data analysis process will record all the clinical data at baseline and every following-up points. The results will be handed over to the statistician for data analysis.
