Veterinary Dentistry Flashcards
How are teeth classified?
Based on the crown and root structure
What are the 2 classifications of teeth
Brachyodont- humans, carnivores and pigs
Hypsodont- horses, rodents and lagomorphs
What are some characteristics of brachyodont teeth?
Small distinct crown, well-developed roots, singular apices, no continuous growth or eruption
What are some characteristics of hypsodont teeth?
Large crown beneath gingival margin, roots characterized by continued grown and eruptuion
Hypsodont teeth divided into what 2 categories?
radicular
aradicular
Describe radicular teeth
Apices remain open for much of adult life- will stop growing late in life, occlusive wear is set off by eruption (cheek teeth in horses)
Describe aradicular teeth
Teeth grow or erupt continuously
In most species an upper jaw wider than the lower jaw is referred to as what?
Anisognathism
What does CUPS stand for?
Chronic ulcerative paradental stomatitis
Which dental probe is best suited for feline p?
The Michigan O probe with Williams’ marking (markings 1-10-missing 4 and 6)
What is the normal sulcus depth in dogs?
0-3mm
What is the normal sulcus depth in cats?
0-1mm
Describe the dental explorer
Slender, wire-like working end that tapers to a sharp point- used to explore topography of tooth
What does CEJ stand for?
Cementoenamel junction
What does attachment loss describe?
Truly describes the state of a tooth as it accounts for both pocket depth and gingival recession
What does abrasion refer to when charting for a dental?
Tooth wear associated with aggressive chewing on external objects (toys, rocks, tennis balls)
What does attrition refer to when charting for a dental?
Refers to wear associated with tooth-to-tooth contact over time
What is a dental carie?
A cavity
What is the periodontium composed of?
Periodontal ligament, gingival connective tissue, alveolar bone forming the tooth socket, cementum covering the surface of the root
What is the most common type of ultrasonic scaler?

How long does it take lidocaine to set in and how long do the effects last?
3-5 minutes- 1.5-2hrs
What does the infraorbital nerve block block?
The infraorbital and rostral maxillary alveolar nerves, and provides analgesia to the incisors, canine, first three premolar teeth, the maxillary bone and surrounding soft tissue
What does the middle mental nerve block block?
Provides analgesia to the incisors and
canine tooth of the corresponding side, as well as the adjacent bone and soft tissues.
What does the inferior alveolar nerve block block?
The entire ipsilateral mandible. Due to the resulting numbness of the tongue, self trauma of the tongue can occur
What does the maxillary nerve block block?
Branches of the maxillary nerve, which are the infraorbital, pterygopalatine, and the major and minor palatine nerves. Blocking affects the bones, teeth, and soft and hard palate
