what are peg teeth and what species are they found in?
second set of maxillary incisors in rabbits
which is softer and wears down more readily – dentine or enamel?
detine
T/F: teeth shape and symmetry differentiate the rodent groups
false
masseter muscle placement does.
What is required in order to assess cheek teeth in small mammals?
a speculum (plastic otoscope or nasal speculum)
What should you make sure you assess in an oral exam on guinea pigs?
the tongue – it can get trapped under their teeth
T/F: rabbits have all open rooted aradicular hypsodont teeth
true!
they grow 10-12 cm per year and can overgrow
T/F: normally, a rabbits mandible sits within the maxilla
true
T/F: malformation of rabbit incisors may cause improper wear of the cheek teeth, eventually leading to the development of sharp points and overgrowth of the cheek teeth.
true
T/F: a malformation of a cheek tooth in rabbits does not usually cause any issues
False – may cause improper occlusion of other cheek teeth or the incisors, causing improper tooth wear and overgrowth.
Rabbit teeth wear by grinding against ____________.
themselves!
