dental anatomy Flashcards
hypsodont
some enamel is below gumline
brachydont
all enamel is above gumline
thecodont
implanted in alveoli
pleurodont
attached to medial surface of bone
acrodont
on top of occlusal surface
carnivore teeth species differences
- carnassial teeth
- brachydont
horse teeth species differences
- incisors- snipping
- hypsodont
- diastema
- canines- rudimentary (undeveloped)
- maxilla wider than mandible
- wolf tooth (1st premolar, often fails to errupt)
rabbit teeth species differences
- diastema
- aradicular hypsodont
- peg teeth
rodent teeth species differences
- pigmented incisors
- diastema
- no premolars
- brachydont
- mandible wider than maxilla
guinea pig teeth species differences
- chisel like incisors
- diastema
- aradicular molars
- mandible wider than maxilla
anatomical crown
full enamel covered part of tooth regardless of whether its above or below the gumline
clinical crown
exposed part of the tooth above gumline regardless of structure
innervation of upper dental arcade
trigeminal nerve V2
innervation of lower dental arcade
trigeminal nerve V3
inferior alveolar branch runs through the mandibular foramen and exits through the mental foramina as mental nerve

guinea pigs are same except 1 premolar
how many roots does dog premolar have?
1st premolar- 1 or 2
2nd, 3rd, 4th- 2
4th upper- carnassial, 3 roots

1st lower molar is carnassial
which premolars of feline are missing?
upper- P1
lower- P1 + P2
P4 of upper arcade has 3 roots
which molars of feline are missing? how many roots?
molars- 2 roots
upper- M2
lower- M2 + M3
supernumerary teeth
- too many teeth
- dental crowding
- malocclusion
blood supply to dental arcades
maxillary artery
blood suply to the mandibular arcade
