Anterior primary teeth Flashcards
Where do primary anterior tooth crown have a bulge?
Bulge is labiolingually in the cervical third
What is the proportion of root to crown ratio for anterior teeth?
Roots are long in proportion to crown length
Primary roots are narrower in which dimension?
Mesiodistally
In which directions do roots of primary anterior teeth bend and by how much?
Bend labially by as much as 10 degrees
In which region of the root do the primary maxillary incisors bend compared to the other incsiors?
bend in the cervical third to half of the root
Which primary incisors are wider mesioditally than incisocervically?
Primary central incisors - only incisors even in permanent teeth
Primary maxillary canine are about as wide in this dimension as they are long in this dimension.
mesiodistal
Incisogingival
Mandibular canines are longer in this dimension and shorter in this dimension.
incisocervically
mesiodistally
Which primary teeth have a longer cusp slope and how is that different for its permanent equivalent?
Primary maxillary canine have longer mesial cusp slope than the distal cusp slope
Permanent maxillary canine have shorter mesial cusp slope and a longer distal cusp slope
What primary tooth and permanent tooth have a longer mesial cusp slope than distal cusp slope?
Primary canine
Permanent maxillary 1st premolar
For primary mandibular canine, which cusp slope is longer?
Distal cusp slope is longer than the mesial cusp slope
Which primary tooth has mesial proximal contacts more cervical then the distal and what is the equivalent primary tooth that has this feature?
Primary maxillary canine because it has a longer mesial cusp slope
Permanent mandibular 1st premolar has more cervical mesial contact than distal contact
