The central cusp, one of morphological anomalies of tooth, is a supernumerary tubercle found principally in the center of the occlusal surface of a molar. Most central cusps reported are observed in the premolar, but very few studies are available on the central cusp in molar, especially in the lower second molar. In the present study, the central cusp on either side of the lower second molar were reported and discussed according to the previous investigation as a supplement on this subject.
中央尖是牙齿形态异常之一,是主要出现在磨牙咬合面中央的额外牙尖。报道的大多数中央尖见于前磨牙,但关于磨牙中央尖的研究很少,尤其是下颌第二磨牙。在本研究中,根据之前的调查报道并讨论了下颌第二磨牙两侧的中央尖,作为该主题的补充。
