45
Describe brachydont teeth
Eruption is determinate: tooth grows, erupts, and then ceases growing and erupting * short crown, long root * entire crown erupts (“extends beyond” gingiva) * entire crown is covered by an external layer of enamel * cementum is restricted to the root
46
Describe hypsodont teeth
Teeth that continuously erupt that accommodates the continuous wear Continuous eruption and wear create a continuum of changes visible on the tooth * Long crown, short root, no real neck * Only a small part of the crown is above the gingiva.
47
What is the anatomic, clinical, and reserve crown
Used to describe crown in hypsodont teeth clinical = visible, above gingiva reserve = non-visuble, under gingiva Anatomic = clinical + reserve crown
48
Which teeth are hypso vs brachydont in the horse
Hypsodont: Incisors and cheek teeth (P3-M3) Brachydont: C and P2, all deciduous teeth
49
Which teeth are hypso vs brachydont in the ruminant
Hypsodont: P and M Brachydont: I and C, all deciduous teeth
50
Which teeth are hypso vs brachydont in carniovores
all teeth types are brachydont (and decidous)
51
What are the carnassial teeth and their function
aka shearing or sectorial teeth upper P4 and Lower M1 in dogs/cats These teeth do not grind; rather, they pass each other like blades of scissors, and really function to cut ingesta into swallowable pieces
52
List the 1 root teeth in the dog and cat
All incisors and canines, 1st premolar (max and mand) Mandibular M3 (only dogs have this)
53
List the 1 root teeth in the cat
All incisors and canines, P2 (max) sometimes maxillary m1 note: cats do not have max P1
54
List the two root teeth in the dog
Maxillary P2, P3 Mandibular P2, P3, P4, M1, M2
55
List the two root teeth in the cat
Maxillary P3 Mandibular P3, P4, M1 Sometimes Maxillary M1
56
List the three root teeth in the dog
Maxillary P4, M1, M2
57
List the three root teeth in the cat
Maxillary P4
58
In what order do decidous and permanent teeth erupt?
Incisor --> canine --> Premolar --> molar Note: no deciduous teeth for molars
59
At what age do dogs and cats have their first permanent teeth
Dog: 3-5 months Cat: 3.5-5.5 months
60
At what age do dogs and cats have all of their permanent teeth
Dogs: 5-7 months Cats: 5-6 months
61
Clinical importance of tooth infection in dogs
Maxillary P4 root is close to maxillary recess and can cause abscess formation is infected
62
Clinical importance of tooth infection in cats
Maxillary P4 root is close to ventral wall of orbit so infection may be seen draining from the eye
63
Ruminant dentition species difference
Upper incisors and canine teeth are absent.
64
What is the dental pad
a thick, keratinized area at the rostral part of the hard palate in ruminants
65
What is the incisiform canine
In ruminants, the lower canines lie immediately adjacent to the lateral incisors (and have a similar shape) * May be referred to as the “corner incisor” or I4
66
List the age at which each permanent incisor erupts in ruminants
I1: 1.5 - 2 y I2: 2 - 2.5 y I3: 3 - 3.5 y I4: 3.5 - 4 y
67
At what age in ruminants are all incisors erupted and worn in
5 years
68
At what age in ruminants are all incisors level or smooth
9 years
69
Equine dentition species difference
Enalmel folded into the tooth for extra strength (creates external enamel and central enamel) Superficial and infundibular cementum
70
What is the infundibulum
In horses, the central enamel creates a central depression formed by the invagination of the enamel Lined by cementum Filled with black debris
71
In horses, list the order age related wear can be seen amongst the incisor teeth
I1 first then I2 and then I3
72
What are points and where and why are the formed What procedure helps reduce points?
Sharp enamel points develop in typical locations due to- 1. Lateral grinding motion of chewing 2. Difference in width of upper jaw and lower jaw 3. Angle of occlusive surface Formed on maxillary buccal and mandibular lingual surfaces Floating
73
Which teeth roots are associated with the rostral maxillary sinus
Maxillary M1 (#'s 109, 209)
74
Which teeth roots are associated with the caudal maxillary sinus
Maxillary M2, M3 (#'s 110, 111 and 210, 211)
75
Clinical signifcance of tooth infection/fracture in horses
Can cause tooth root abscess in maxillary sinus
76
What are wolf teeth
P1 in horses (vestigial) variable erupts (not present in every individual) Often fall out when P2 erupts Or removed due to ‘bitting’ problems (less so now, only removed if causing problems) Does not erupt on mandibular arcade
77
Name the different ways we can age a horse according to its teeth
Eruption times of deciduous teeth Eruption times of permanent teeth Structures of the mandibular incisors in wear Shape of the mandibular incisor ‘table surface’ Hooks Galvayne’s groove Angle of the incisors in profile
78
Name and define structures in the mandibular incisor used to age a horse
Cup: The food stained space in the infundibulum Enamel spot: The bottom of the infundibulum Dental star: Secondary dentin covering the pulp cavity
79
Cups, enamel spots, and dental stars are evaluated where?
Mandibular incisors
80
Shape/ table surface is evaluated where?
Mandibular incisors
81
Where are hooks evaluated?
Maxillary I3 (upper corner incisor - UCI)
82
Where is Galvayne's groove evaluated?
Maxillary I3 (upper corner incisor - UCI) Compare both sides!
83
How does incisor angle in profile change with age in a horse?
More angular with age
