JVD 2016 #1 - Measuring Rabbit (Oryctolagus cuniculus) Tooth Growth and Eruption by Fluorescence Markers and Bur Marks Flashcards
According to “Measuring Rabbit (Oryctolagus cuniculus) tooth growth and eruption by fluorescence markers and bur marks” by Wyss, Hatt et al,
what is meant by the term hystricomorph rodents? what type of teeth do these rodents and lagomorphs have?
means rodents with zygomassenteric specialization,
hyposodont. elodont, aradicular teeth (all teeth, unlike other rodents with closed premolars/molars), ex are porcupine, chinchillas, GPs, capybaras;
lagamorphs are hypsodont, elodont, aradicular.
According to “Measuring Rabbit (Oryctolagus cuniculus) tooth growth and eruption by fluorescence markers and bur marks” by Wyss, Hatt et al, what 3 types of diagnostics were performed to measure tooth growth?
Manual bur marks on teeth, CT for apical to coronal measurement, and fluorescence microscopic images of teeth
According to “Measuring Rabbit (Oryctolagus cuniculus) tooth growth and eruption by fluorescence markers and bur marks” by Wyss, Hatt et al,
what were the 2 groups of rabbits
what were the 2 fluorescence markers used?
6 rabbits; 3 on all grass hay, 3 on grass, rice hull pellets and sand;
2-5d post diet change SQ injection of calcein green;
10d later SQ injection xylenol orange.
euthanized 11 days later for final analyses (21d after injection of calcein green)
According to “Measuring Rabbit (Oryctolagus cuniculus) tooth growth and eruption by fluorescence markers and bur marks” by Wyss, Hatt et al, was there correlation btwn the different modalities?
Sig correlation btwn manual and CT measurements.
According to “Measuring Rabbit (Oryctolagus cuniculus) tooth growth and eruption by fluorescence markers and bur marks” by Wyss, Hatt et al, were the authors able to draw any conclusions regarding overall growth/eruption and diet?
No due to small sample size. Anecdotally, rabbits in hay groups had a slower more normal growth rate.
