中文百科

齿列

人类上腭铸型:门齿、犬齿、小臼齿和全套三枚臼齿中的两枚。

齿列(亦作牙列齿系牙系)指的是动物口腔中全套牙齿的发育和排列模式。

除单孔目、贫齿目、穿山甲属和鲸目以外,所有哺乳动物都具备四种类型的牙齿,而且每一类型的牙齿,与物种相应,都有固定的最大数目。这四个类型分别为:门齿(门牙,incisor)、犬齿(canine)、小臼齿(前臼齿,premolar)和臼齿(molar)。其中的人类的前后臼齿,通常也被称作槽牙。符合这种类型划分的齿列被称作异形齿(heterodont),否则则称作同形齿(homodont)。

各类型牙齿的数目可用对应单侧(左侧)上下两列牙齿的两行结构式来描述,而口腔内牙齿的总数则是结构式所记数目的两倍(牙齿的排列左右对称)。具体而言,结构式每行从左到右依次为门齿数、犬齿数、小臼齿数和臼齿数。例如齿列上部结构式2.1.2.3所表示的就是门齿两枚、犬齿一颗、小臼齿两颗和臼齿三枚,所对应的是口腔上腭一侧的牙齿。
