Teeth with large fillings or crowns, suspected pulpitis, caries, wedge-shaped defects, enamel cracks, or abutment teeth of removable partial dentures 5. They have a history of allergy or idiosyncratic reaction to oral hygiene products or their components; 6. They are allergic to toothpaste and its components; 7. Women who are pregnant or lactating; 8. They have used the following drugs within one month before participating in the study: anticonvulsants, antihistamines, antidepressants, sedatives, and tranquilizers; 9. They have used other anti-dentin hypersensitivity toothpaste; or are participating in other similar clinical trials at the same time; 10.There are any diseases or conditions that the researchers consider may affect the examination procedures and the safety of the subjects to complete the trial.

随机方法(请说明由何人用什么方法产生随机序列):

随机表存储在一个安全的并限制访问文件夹。随机表的副本将被发送给的负责产品分配和产品应用培训的工作人员手中。在随机化过程中,应打印该副本以便在研究中心完成随机化。随机化ID和相应的治疗应转录到临床研究病历中。指定的研究中心人员负责保持随机化的完整性和设盲。原始填写完整的列表应保留在研究中心主文档中,供监查员审查,以确保其依从性。一旦完成研究,随机表将被合并到数据库进行数据分析。

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

The randomization list shall be securely stored in an access-restricted folder, with a copy provided to personnel responsible for investigational product allocation and administration training. During the randomization process, a printed copy shall be utilized at the study site. Randomization IDs and corresponding treatments must be accurately transcribed into Case Report Forms (CRFs), with designated site staff maintaining randomization integrity and blinding procedures. The original completed list shall be retained in the site master file for monitor verification to ensure compliance, and will ultimately be incorporated into the database for statistical analysis upon study completion. This procedure ensures proper documentation while preserving blinding throughout the trial in accordance with ICH-GCP guidelines for clinical trial management.

是否公开试验完成后的统计结果:
