The development of the pharyngeal dentition was examined in 13 species of five subfamilies of the family Cyprinidae. A previously described difference between the larval and adult dentition in Gnathopogon caerulescens was observed in 11 species of Gobioinae, Cyprininae, Leuciscinae, and Danioinae, but was not seen in two species of Acheilognathinae. The adult dentition is usually complete by the later larval or juvenile period. In the adult dentition, the functioning teeth are generally shed at each position, when the replacement tooth has been ankylosed to the bone, or when the germ of that tooth has grown sufficiently. In the larval dentition, however, the replacement tooth is ankylosed medial to the functioning tooth, so the older functioning tooth is retained after ankylosis of the replacement tooth. That is why the dentigerous surface of the bone grows rapidly during the larval period. Each tooth row represents a single replacement wave. The distribution and pattern of the central teeth are exactly the same in all types of the larval dentition. However, those of the anterior teeth vary between and within different species. The larval dentition develops into the major row of the adult dentition through tooth replacements. The number of tooth families in the larval dentition is completely consistent with the tooth number of the major row in the adult dentition. Therefore, the number of major row teeth owes its variation to that in the appearance pattern of the anterior teeth.
对鲤科五个亚科的13个物种的咽齿发育进行了研究。在颌须鮈属、鲤属、雅罗鱼属和丹尼奥属的11个物种中观察到了先前描述的青眼颌须鮈幼体和成体齿列之间的差异，但在鱊属的两个物种中未观察到这种差异。成体齿列通常在幼体后期或幼年期完成。在成体齿列中，当替换牙与骨 ankylosed（骨结合）时，或者当该牙的牙胚充分生长时，各位置的功能牙通常会脱落。然而，在幼体齿列中，替换牙在功能牙的内侧 ankylosed，所以替换牙 ankylosed 后，较老的功能牙会保留下来。这就是为什么在幼体期骨的牙附着面会快速生长。每排牙齿代表一个单一的替换波。在所有类型的幼体齿列中，中央齿的分布和模式完全相同。然而，不同物种之间以及同一物种内部，前牙的分布和模式有所不同。幼体齿列通过牙齿替换发育为成体齿列的主要排。幼体齿列中的牙家族数量与成体齿列主要排的牙齿数量完全一致。因此，主要排牙齿数量的变化归因于前牙出现模式的变化。
