UNIT-1

dental plaque 牙菌斑

S.sanguis 血链球菌

S.mitis 轻链球菌

S.mutans 变形链球菌

aerobic 好氧的，氧气的；依靠氧气的

anaerobic 没有空气而能生活得，厌氧的

1.In contrast to mucosal surface,the surface of teeth are not constantly renewed by shedding of

colonized epithelial cells.

较之粘膜，牙面不能稳定地通过上皮脱落而更新。

2. Selective manner in which bacteria attach to the tooth surface is thought to reflect the fact that

bacteria on their surface contain a recognition system which enables components on the bacteria surface (adhesions) to blind to complementary molecules (receptors) in the pellicle. 细菌附着与牙面的选择性方式反映了这一事实，即细菌表面具有识别系统，该系统能使细

菌表面的附着器与获得性膜中的互补手提分子结合。

UNIT-2

ecology 生态学；个体生态学

ecosystem 生态系统（学）

mutanism 突变的

S.sanguis 血链球菌

S.mutans 变形链球菌

1.Colonization is a complex process, as it involves not only interaction between bacteria and

their environment but aslo bacterial interactions.

定植是一个复杂的过程，它不仅包括细菌和环境间的相互作用，也包括细菌之间的相互作

用。

2.Tooth eruption has a major impact on the composition of oral flora.This is to be expected, as

teeth provide new types of surfaces and new microenvironments.

牙齿的萌出对口腔菌群组成有重要影响。这是因为牙齿提供了一些新型的表面和新的微环境。

UNIT-3

saliva 唾液

parotid 耳旁的；腮腺的

lingual 舌的，语言的，舌侧的

buccal 颊的，颊侧的

labial 唇的，唇侧的

palatine 腭的

edentulous 无牙

sulculus 小沟

mastication 咀嚼

chew 嚼，咀嚼

temporomandibular joint (TMJ) 颞下颌关

节

streptococci 链球菌

fungus (复fungi) 真菌，霉菌

1.The salivary amylase activity of differenr individuals varies but a weak action is

compensated for by the strong action of pancreatic amylase in the duodenum.

不同个体间唾液淀粉酶的活性不同，但是较弱的活性可由十二指肠中强活性的胰淀粉酶补偿。

UNIT-4

enamel 釉质

dentinal tubules 牙骨质小管

amelocemental junction 釉牙骨质界

dentine 牙本质

cementum 牙骨质

odontoblast 成牙本质细胞

alveolar bone 牙槽骨

alveolar crest 牙槽嵴

junctional epithelium 结合上皮

1.The tooth bud undergoes peripheral proliferartion into the mesenchyme, leaving a central

mensenchyme-filled depression, to form the tooth cap which consistants of the same

components as the tooth bud.

牙蕾的周边区上皮向外胚间充质中生长，基底部凹陷，状如帽子，凹陷内充满外胚间充质细胞，帽状期上皮与蕾状期相同。

2.Dentine consists of mineralized tissue (chiefly hydroxyapatite) in which microscopic

tubules are found extending from the pulp to very close to, or even through, the

amelodentinal junction.

牙本质由矿化组织（以羟基磷灰石为主）构成，镜下见有小管自牙髓贯穿全层到达或穿过釉牙本质界。

UNIT-5

dentine permeability 牙本质渗透性

remineralization再矿化

groove窝沟

slot (固定)沟

undercut retention 倒凹固位

cariogenic 致龋的
