队列研究 

Study design:

Cohort study 

研究目的:

建立大样本临床队列,通过对苦味受体T2R38基因多态性筛查、口腔微生物群落分析以及牙周健康状况的临床检查,探究T2R38基因多态性在牙周炎发生发展及治疗预后中的作用,建立基于椅旁苦味测试的牙周炎易感性及治疗预后预测模型,辅助牙周炎临床诊疗。  

Objectives of Study:

Establish a large sample clinical cohort to explore the role of hT2R38 gene polymorphism in the development and prognosis of periodontitis through screening of bitter taste receptor hT2R38 gene polymorphism, oral microbiome analysis and clinical examination of periodontal tissue. Our research also aimed at establishing a model of periodontitis susceptibility and prognosis of treatment based on bitterness test during clinical process, to assist in the clinical diagnosis and treatment of periodontitis

随机方法(请说明由何人用什么方法产生随机序列):

本项研究不使用随机方法,在第一部分的诊断模型的构建中,根据牙周健康情况分为牙周炎组和健康组,并通过基因测序对每个组别划分亚组。在第二部分的预后模型构建中,将根据基因测序划分组别,分别为非AVI组(包括基因型为PAV/PAV和PAV/AVI)和AVI组(仅包括基因型为AVI/AVI)

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

This study does not use any random method. In the first part for diagnostic mode construction, volunteers are divided into a periodontitis group and a healthy group according to periodontal tissue status, and each group is divided into subgroups by gene sequencing. In the second part for the prognostic
