[Considerable supplement on the central cusp in the lower second molar].
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.
