Principles and practice of operative dentistry . Fig. 63. Mesio-huccalcusp Buccal groove-Superior right third molar, buccal surface.(Enlarged.;. Mesialgroove Lingual cusp-Superior right third molar, lingual surface.(Enlarged.) CLASSIFICATION AND DESCRIPTIVE ANATOMY OF THE TEETH. 19 only rudimentary in size, and the oblique ridge prominent, the tooth be-comes practically a three-cusped tooth. The various grooves are the sameas on the first molar in the normally developed organ. The cervix is less regular in outline and more constricted and flattenedmesio-distally than in the first molar. The roots are the same in number and general form as in the first molar ;they spread less, however, and are quite inclined to be crooked or convergetowards each other, or to be fused together. Sometimes the buccal roots only are fused, while in others the mesialand lingual are joined, or all of the roots may be united in a single root,the outlines of the roots being marked only by shallow grooves. The pulp-canals in a normally developed superior second molar are, asa rule, smaller and more difficult to enter than those of the first molar. When
