摘要
该文报道1例下颌前磨牙区多生前磨牙患者,多生牙与正常的前磨牙大小、形态冠根比例等无明显区别。其病因可能是牙胚的分裂和增殖异常造成的。
A case of several ambushed bicuspoid supernumerary teeth in the premolar area was reported.The size,shape and the ratio of crown to root of the supernumerary teeth are similar to those of the premolar.The abnormity of tooth germ division and proliferation may lead the supernumerary teeth.
