研究目的:

本研究欲研发检测牙周炎患者龈沟液中炎症因子(IL-1β,MMP-8和TNF-α)、micro RNA(miR-146a和miR-155)的即时检测平台.通过长期监测患者治疗随访期间各因子变化情况,辅助医生判断牙周炎的即时状态。  

Objectives of Study:

To develop a point-of-care testing system for the detection gingival crevicular fluid inflammatory factors (IL-1β,MMP-8 and TNF-α) and miRNA (miR-146 and miR-155) in periodontitis patients. To assist dentists judging the present states of periodontitis by monitoring level changes of these factors during the treatment and the follow-up in the long term.
