Lobe: one of the 1° section of formation in the development of the crown; cusps and mamelon are representations of lobes Tubercle: smaller elevation on some portion of the crown produced by extra enamel formation ( deviations from normal form ) Mamelon: 1 of 3 rounded protuberances found on the incisal ridges of newly erupted incisor teeth Cingulum: lingual lobe of an anterior tooth Cusp: any of the cone-shaped prominences/elevation/mound on crown; makes divisional part of occlusal surface Ridge: any linear elevation on the surface of a tooth ( named by location ex. Buccal ridge ) Marginal ridge: rounded borders of the enamel that form the mesial and distal margins of lingual surfaces of anterior teeth and occlusal surfaces of posterior teeth Triangular ridge: descend from tips of cusps of molars/premolars towards central part of the occlusal surface ( named for the cusps they belong to forming triangle ). Traverse ridge: union of 2 triangular ridges (buccal and lingual triangular ridges) crossing transversely the surface of a posterior tooth Oblique ridge: a ridge crossing obliquely the occlusal surface of maxillary molars (distal to lingual) 2.Depressions Fossa: irregular depression or concavity Lingual fossae: fossa on the llingual surface of incisors Central fossae: fossa on occlusal surface of molars; formed by the converging of ridges terminating at a central point in the bottom of the central point in the bottom depression where there is a junction of grooves Triangular fossae: on posterior teeth’s occlusal surfaces mesial or distal to marginal ridges; in incisors at the edge where marginal ridges and cingulum meet.
