第一部分牙龈病 gingival diseases
牙龈病是指一组发生于牙龈组织的病变,包括牙龈组织的炎症及全身疾病在牙龈的表现。牙龈病一般不侵犯深层牙周组织。
1999年新的分类法将牙龈病分为:
菌斑引起的牙龈病;
非菌斑引起的牙龈病;
Ⅰ. Gingival Diseases
A. Dental plaque-induced gingival diseases 1. Gingivitis associated with plaque only 2. Gingival diseases modified by systemic factors a. associated with the endocrine system b. associated with blood dyscrasias 3. Gingival diseases modified by medications 4. Gingival diseases modified by malnutriation
B. Non-plaque-induced gingival lesions
1. Gingival diseases of specific bacterial origin 2. Gingival diseases of viral origin 3. Gingival diseases of fungal origin 4. Gingival lesions of ic origin 5. Gingival manifestations of systemic conditions 6. Traumatic lesions (factitious,iatrogenic,accidental) 7. Foreign body reactions 8. Not otherwise specified(NOS)
菌斑引起的牙龈病
一、慢性龈炎(慢性龈缘炎)
marginal gingivitis 边缘性龈炎
simple gingivitis 单纯性龈炎
1、病因 始动因子:牙菌斑 促进因子:牙石、食物嵌塞、不良修复体
2、临床表现:
局限性:龈乳头炎 广泛性:弥散性龈炎
①牙龈色、形、质的改变
②龈沟深度的改变>3mm (正常2~3mm ) ,但无附着丧失,这是区别牙龈炎和牙周炎的重要标志。
③探诊出血:诊断牙龈有无炎症的重要客观指标
④龈沟液增多:测量龈沟液可作为判断牙龈炎症程度的指标。
