Canines Flashcards
Upper right canine identification markers?
Dimond shaped with pointed cusp instead of incisal edge
Convex with prominent ridge running to end of cusp
Medial cusp slope (mesial border) shirted and less steep that distal cusp slope (shoulders of tooth not equal)
Longest and strongest root of teeth ( as of function - corner of mouth acts to take grinding forge off other teeth - canine guidance in lateral movement)
Palatal size generally divided into two shallow fossae separated by the labial ridge from cingulum to cusp
Mesial cervical line more curved
Mesial contact (the crest of curvature) locates more Incisally
Distal crest of curvature generally at centre of crown
Cingulum and marginal ridges very prominent
Labial surface almost vertical
Pulp squeezed mesiodistally
Root flattened mesiodistally
Lower right canine identification markers?
Less diamond shaped, More small, weak and symmetrical as flatter mesiodistally so narrower and more slender
Cingulum, fossae and marginal ridges much less prominent
Mesial border of cusp shorter and less steep than distal
Labial surface lingually inclined = cusp in lingual position (inclined tip not present in upper)
Mandibular cusp less prominent and flatter
Line from root tip in upper is straight to cusp but in lower at cervix, crown central line is squint to distal side
Enamel extends further on lingual side (equal on uppers)
Both spinal shaped pulp but as lower root compressed more mesiodistally so too is pulp
