牙周病是局部细菌及其代谢产物与宿主反应相互作用的结果,它的基本病理改变是炎症,中性白细胞是机体抗感染中重要反应细胞,它在牙周疾病与健康中的作用,已受到不少学者的重视,特别是近年来发现青少年牙周炎患者有中性白细胞功能障碍存在,引起了众多研究者的兴趣,青少年牙周炎已成为研究中性白细胞功能与细菌感染相互关系的极好模型。本文就国外对青少年牙周炎患者中性血细胞功能研究的状况作一综述,并提出今后这方面的研究方向。一、青少年牙周炎患者中性白细胞功能特点近二十年来,局部细菌及其代谢产物在牙周病发生发展中的作用已变得非常清楚。另一方面,个体的敏感性即宿主反应又在很大程度上影响牙周病变的发生发展,青少年牙周炎发生年龄早,病 Periodontal disease is the result of the interaction of local bacteria and their metabolites with the host reaction. Its basic pathological changes are inflammation. Neutrophils are the important reactive cells in the body's anti-infective. It plays an important role in periodontal disease and health. Many scholars have paid attention to it. Especially in recent years, it has been found that there are neutrophil dysfunction in adolescents with periodontitis, arousing the interest of many researchers. Adolescent periodontitis has become the study of the relationship between neutrophil function and bacterial infection Excellent model. This review summarizes the research on the function of neutrophils in adolescents with periodontitis in foreign countries and puts forward the research direction in this field in the future. First, the characteristics of neutrophils in patients with periodontitis in young people Nearly two decades, the role of local bacteria and their metabolites in the development of periodontal disease has become very clear. On the other hand, the sensitivity of the individual that host reaction and to a large extent affect the occurrence and development of periodontal disease, adolescent periodontitis occurs early,
