Crowns of mandibular molars are wider mesiodistally than faciolingually. Note that the opposite is True of maxillary molars. Mandibular molars have two roots: one buccal and one lingual. The cusp of Carabelli is not located on a mandibular molar; it is found on the maxillary first molar. It is True that the occlusal groove on the second molar is well established.
