DENT3060 Lecture Notes - Lecture 14: Incisor, Hypoplasia, Palmer Notation
Document Summary
Labial surface smooth: no mamelons incisal edge nearly straight, cingulum and marginal ridges prominent, root: cone shaped with tapered sides, similar to central but smaller in all dimensions. Incisal angles more rounded: apex is sharper. Larger than 1st molar: 4 cusps (ml, mb, db, dl and sometimes cusp of carabelli, root: 3 (mb, db, p) Incisal edge straight: root: approx. twice length of crown, similar form to central wider and longer, disto-incisal angle is more rounded, root: distal curvature. Incisal edge slopes distally: distal cusp slope is longer than mesial, root: longer, slender, tapering and distal inclination, unlike any other tooth in dentition, four cusps: ml, mb, db, dl (mesials larger, roots: 2. Molar: oval occlusal shape, resembles 1st permanent molar, five cusps: db, mb, d, ml, dl, roots: 2 in number, long and slender. Primary teeth terminology: baby teeth, milk teeth, deciduous teeth, temporary teeth. Primary dentition: 20 teeth incisor (4), canine (2), molar (4)
