研究目的:

通过多组学技术筛选与牙周病患病风险相关的生物标记物,整合牙周病专病临床资料和影像学结果,建立多模态牙周炎患病风险和治疗有效性预测模型,达到牙周炎的早期诊断和治疗有效性预测,为牙周炎的群防群治提供依据。  

Objectives of Study:

By utilizing multi-omics technologies to screen biomarkers associated with the risk of periodontal disease, and integrating disease-specific clinical data with imaging findings, we aim to establish a multimodal predictive model for periodontitis risk and treatment efficacy. This model will enable early diagnosis of periodontitis and prediction of therapeutic outcomes, thereby providing a scientific basis for population-based prevention and treatment strategies.

Measure method:

Gingival recession is measured using a periodontal probe to determine the vertical distance from the cementoenamel junction (CEJ) to the gingival margin.
