青少年牙周炎的患病率虽不如成年人慢性牙周炎高,但它引起患者早年缺牙,影响患者的身心健康,是近年来研究的重点。1976年Lavine首次报告青少年牙周炎患者周缘血中性白细胞的趋化功能有缺陷。此后,Cianciola、Clark和Lavine等相继于1977和1979年发表关于青少年牙周炎患者白细胞的趋化和吞噬功能的研究。迄今的研 Although the prevalence of adolescent periodontitis is not as high as that of chronic periodontitis in adults, it causes edentulous teeth in early years and affects the physical and mental health of patients.

Since then, Cianciola, Clark and Lavine, etc. published in 1977 and 1979, leukocyte chemotaxis and phagocytosis in adolescents with periodontitis. Research so far
