人体组织学： 牙；

动物学： ［牙］齿；

医学： 牙：颌部用于咀嚼食物的一副坚硬小结构，亦指其他动、植物中的类似结构。人类的牙齿有两副，即乳牙(暂牙)和恒牙。每颗牙齿都有两个主要部分，即牙冠和牙根，进一步还可分为冠、颈、根、尖四部分。除髓腔外，牙的质地坚硬，主要是由牙质构成。牙冠部披覆一层极为坚硬的无机物釉质，主要在龈线以上部分，埋入颌骨的牙根部则覆有一薄层牙骨质，为真骨组织。髓腔可分为两部分，主要在牙冠内的髓室和通过牙根终于根尖狭孔的髓管(牙根管)。每个牙根至少有一个髓管，即使多根牙也是这样。髓腔中含有牙髓，为由结缔组织、血管和神经构成的软组织。出牙一般是按以下规律发生的：乳牙——第一切牙，6～8月；第二切牙，7～9月；第一磨牙，12～14月；犬牙，16～18月；第二磨牙，20～24月。恒牙——第一磨牙，6～7岁；第一切牙，6～8岁；第二切牙，7～9岁；前磨牙(双尖牙)，10～12岁；犬牙，9～12岁；第二磨牙，11～13岁；第三磨牙：17～21岁。参见dentition； 上颌前后牙剖面示意图：左前牙：A 根尖，AF 根尖孔，SC 附加管，C 牙骨质，PM 牙周膜，PC 髓管，G 牙龈，GC 龈沟，GM 龈缘，PCH 髓腔，D 牙本质，E 牙釉质，CR 牙冠，R 牙根；右后牙：A 根尖，PC 髓管，PCH 髓腔，PH 髓角，F 牙沟，CU 牙尖，CEJ 牙骨质-釉质结合点，BI 牙根分叉；
