Maxillary first molar; occlusal surface irregular rhombic inoutline with four cusps (two buccal, two lingual) ; mesiobuccalcusp largest; distolingual cusp distinctly marked oil from theother cusps by a deep groove; three roots (1) mesial or mesio-buccal, (2) distal or distobuccal, (3) lingual; (3) largest,conical in form, circular in cross-section; mesial root larger thandistal, oval in cross-section, with buccolingual axis the longer;distal root also has the same eross-section (Fig. 154). Maxillary second molar; smaller than above tooth; other-wise greai similarity; distolingual cusp noticeably reduced; three roots, closely resembling those of above tooth. 420 HUMAN ANATOMY. Maxillary third molar; same structural form as the twoabove teeth, but many variations; cusps more poorly marked;distolingual cusp often absent; smallest tooth of the molar. Fig. 153.
