tooth词源中文解释

古英语 toð（复数 teð），源自原始日耳曼语 *tanthu-（也源自古撒克逊语、丹麦语、瑞典语、荷兰语 tand，古诺尔斯语 tönn，古弗里斯兰语 toth，古高地德语 zand，德语 Zahn，哥特语 tunþus），源自 PIE 词根 *dent- “牙齿”。复数 teeth 是i-mutation的一个例子。

在古英语、古弗里斯兰语和古撒克逊语中，失去 -n- 在擦音前是常规的：比较 goose（名词）， five， mouth（名词）。还有 thought，来自 think 的词干； couth 来自 can（v.1）的词干； us 来自 *uns。

首次记录牙齿状物体（锯子、梳子等）的应用是在1520年代。作为武器的 Tooth and nail 是从1530年代开始的。tooth-fairy 的出现可以追溯到1964年。

tooth_医学行业词汇

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
