牙  又称牙齿。人体中最坚硬的高度钙化的组织器官。主要功能是咀嚼食物和辅助发音,并与保持面部正常形态有密切关系。每个牙可分三部分,即露出牙槽骨外的牙冠、嵌人牙槽内的牙根和两者间的牙颈。人的一生中要长两次牙,先长的一副叫乳牙,后长的一副叫恒牙。根据牙的位置、开头和功能可分为:切牙(门齿)、尖牙(犬齿)、双尖牙(前磨牙)、磨牙(臼牙)等四种类型。牙冠和牙根的表面分别为牙釉质和牙骨质,里面均为牙本质。牙齿中间有牙髓腔,其内充满牙髓,具有生成牙本质和营养牙组织的功能。牙髓中有丰富的血管、神经和淋巴管,它们通过牙根尖端的小孔与来自牙槽骨和牙周膜的血管、神经相连。牙易生病,主要为龋齿(详见“龋齿”)和牙周病。牙周病是牙齿周围的支持组织发生各类疾患的总称,主要包括牙周膜,牙槽骨和牙龈的病变。牙周病的发病原因虽复杂,但以口腔不洁为最常见。由食物残渣、脱落的口腔上皮组织、细菌和唾液里的粘液混合而成的污垢(牙垢)及唾液中所含的矿物质沉积在牙垢上形成坚硬的牙石,附着于牙面,对牙周组织会桢机械刺激作用。在牙垢和牙石内的细菌大量繁殖并产生毒素又刺激牙周组织而引起慢性炎症,可造成牙龈水肿、充血。因此牙周病如不及时治疗,就会破坏牙周膜的纤维和牙槽骨,最终导致牙齿的松动与脱落。牙周病的治疗多采用综合措施,如提高身体抵抗力;正确刷牙,保持口腔卫生;施行牙周洁治,去除牙石,根据具体情况选用特制的钢丝夹板固定,或进行牙周病手术治疗等。为使人人都有一副好牙齿,1989年中国卫生部、文化部、总工会等9个部委联合发起,将每年9月20日定为全国“爱牙日”。
