青少年牙周炎

青少年牙周炎与补体第三组份、备解素因子B遗传多态性的相关性研究

Association of juvenile periodontitis with genetic polymorphism of the third component of the complement and properdin factor B

方法：采用免疫组化方法，检测15例健康人、32例成人牙周炎（AP）和12例青少年牙周炎（JP）患者牙龈的EGFR表达。

METHODS : The expression of EGFR was determined by using immunohistochemical techniques in gingival tissue of 15 healthy individual , 32 cases with adult periodontitis ( AP ) and 12 cases with juvenile periodontitis ( JP ) .

其MDA水平明显高于健康老年人、成人慢性牙周炎患者和青少年牙周炎患者（P<0.05）。

Level of MDA in elderly patient group was significantly higher than those of healthy elderly , adult patient and juvenile patient group ( P < 0.05 ) .

慢性成人牙周炎组和青少年牙周炎组结缔组织中淋巴细胞和吞噬细胞Fas/Apo-1（CD95）抗原阳性表达强于健康老年人组；

The positive expressions of Fas / Apo-1 ( CD95 ) antigen on the lymphocytes and phagocytes in connective tissues of gingiva in adult patients and juvenile patients with periodontitis were stronger than those in healthy elderly peoples .

结果表明：IgE含量正常对照组明显低于患者组，特别是与青少年牙周炎组IgE含量相差4倍。

IgE level in the control group was significantly lower than that in the periodontal disease groups ( P < 0.01 ) . IgE level in the control was only 1 / 4 of that in the juvenile periodontitis . The level of IgM rose only in the gingivitis group .

Gram Negative Species Associated with Juvenile Periodontitis

局限型青少年牙周炎和快速进展型牙周炎的治疗方法一般选用四环素纤维膜。

The limitation young people parodontitis and the fast progress parodontitis method of treatment selects the tetracyclin textile fiber membrane generally .

目的：研究老年牙周炎患者外周血中性粒细胞趋化功能和吞噬功能，并与成人慢性牙周炎、青少年牙周炎的中性粒细胞趋化和吞噬功能比较。

Objectives : Research on the functions of neutrophil leukocytes in elderly patients with periodontitis , matched with adult and juvenile patients .

结果：老年牙周炎患者中性粒细胞移动指数明显低于成人慢性牙周炎和青少年牙周炎患者（P<0.05，P<0.01）；吞噬能力和吞噬活性均较成人慢性牙周炎和青少年牙周炎患者明显减低（P<0.01）。

Results : Chemotaxis and phagocytosis of neutrophil leukocytes in elderly patients were much lower than those in adult and juvenile patients ( P < 0.05 , P < 0.01 ) .

从24例正常人、34例成年人牙周炎和18例青少年牙周炎患者龈下分离和鉴定了23种共296株革兰氏阴性无芽胞厌氧菌。

The 296 strains affiliated to 23 genera of anaerobic bacteria without spores were isolated and differentiated from subgingival samples of 34 adult patients with periodontitis . 18 with juvenile periodontitis , 24 normal subjects . B. melaninogenicus , B. gingivalis , A.
