Anatomy and Development Flashcards
In Schrock’s 2013 study “Three-dimensional anatomy of equine incisors: tooth length, enamel cover and age related changes,” equine incisors reach their maximum length how many years post eruption, and after what tooth age does the tooth length start to decrease rapidly?
Staszyk BMC Veterinary Research 2013
Maximum length 2-4 years
decrease rapidly after 13-15 years
In Schrock’s 2013 study “Three-dimensional anatomy of equine incisors: tooth length, enamel cover and age related changes,” identations are present in the enamel of what surfaces of the teeth, and enamel reaches further apically on the labial or palatal sides of the teeth?
Staszyk BMC Veterinary Research 2013
Indentations: mesial and distal
Enamel reaches further on labial surface
In Schrock’s 2013 study “Three-dimensional anatomy of equine incisors: tooth length, enamel cover and age related changes,” what incisors are stat sig longer than the others in the upper and lower quadrants respectively?
Staszyk BMC Veterinary Research 2013
Upper: middle
Lower: corner
In Sahara’s 2014 paper “Development of Coronal Cementum in Hypsodont Horse Cheek Teeth,” this image of a mandibular fourth premolar occlusal surface is most consistent with what age horse?
The Anatomical Record 2014
3.5 years
In Sahara’s 2014 paper “Development of Coronal Cementum in Hypsodont Horse Cheek Teeth,” how was the resorption of enamel evaluated with histochemistry?
tartrate-resistant acid phosphatase (TRAP) activity as a marker for odontoclasts and their precursors using the azo-dye method
Study showed for the first time that prior to coronal cementogenesis TRAP-positive odontoclasts resorbed the enamel surface of the reserve crown in horse cheek teeth
In Sahara’s 2014 paper “Development of Coronal Cementum in Hypsodont Horse Cheek Teeth,” what are the structural composition differences between infolding and peripheral cementum?
Infolding cementum: free from extrinsic collagen fibers (Sharpey’s fibers), cellular with abundant blood vessels, maintains occlusal surface
Peripheral cementum: contains Sharpey’s fibers and provides anchorage for PDL, tertiary cementum thickest in subgingival region
Secondary and tertiary cementum provides sites for insertion of the PDL
In Omura’s 2015 paper “Measurement of Incisor Overjet and Physiological Diastemata Parameters in Quarter Horse Foals,” maximum growth of the maxillary and mandibular diastemata occured in what age group?
JVD 2015
4-5 months old
In Omura’s 2015 paper “Measurement of Incisor Overjet and Physiological Diastemata Parameters in Quarter Horse Foals,” overjets were most common in what sex of Quarter horses of what lineage?
JVD 2015
female Quarter horses of show lineage
