What is the crown?
the portion of tooth above the gum line, covered by enamel.
What is the root?
The portion of the tooth below the gum line, covered by cementum
What is enamel?
The hardest tissue in the body.95% calcium. Formed by ameloblasts- cannot repair itself
What is dentin?
2nd hardest tissue in the body. Covered by enamel on the crown and cementum on the root. Formed by odontoblasts. Can repair itself. (tertiary dentin=brown spot)
What is cementum?
Covers root. Protects dentin and seals openings of dentinal tubules. Formed by cementoblasts.
What is pulp cavity?
Soft tissues of the tooth- odontoblasts, arterioles, venules, nerves, connective tissue. Cannot expand.
What is the apex or apical delta?
entry of blood vessels, nerves and lymphatics at bottom of root.
What is periodontal ligament?
net-like elastic ligament attaching cementum to bony alveolus- shock absorber
What is alveolus?
bony socket where tooth resides. Tip=alveolar crest-declines during lifetime orif diseased.
What is gingiva?
Gum tissue. Protects bone and attachment of tooth. Each tooth has collar of gingiva.
What is gingival sulcus?
The attachment of gingiva to cementum. Normal depth in dogs = 0-3mm/ feline = 0-1mm
What is furcation?
the space between the roots of a tooth
what is apical?
towards the root
coronal
towards the crown
cervical
toward the neck- junction of the coronal and apical tooth
mesial
toward the midline of the dental arch
rostral
toward the front of the head-also mesial in the cheek teeth.
distal
away from midline of the dental arch- also caudal in the cheek teeth.
buccal
surface facing the cheeks
facial
surface facing the front lips
labial
surface facing the cheeks in the mandible.
lingual
surface of mandibular teeth facing the tongue
palatal
surface of maxillary teeth facing the hard palate
sublingual
surface beneath the tongue
interproximal space
space between adjacent teeth
interproximal surface
the adjacent surfaces of two adjoining teeth
incisal
biting surface of incisors
occlusal
grinding surface of the molars
when do deciduous teeth erupt in dogs?
3-4 weeks for incisors, 3 weeks for canines and 4-12 weeks for premolars
when do deciduous teeth erupt in cats?
incisors= 2-3 weeks
canines= 3-4 weeks
premolars= 3-6 weeks
when do permanent teeth erupt in dogs?
incisors= 3-5 months
canines= 4-6 months
premolars= 4-6 months
molars= 5-7 months
when do permanent teeth erupt in cats?
incisors= 3-4 months
canines= 4-5 months
premolars= 4-6 months
molars = 4-5 months
what is the dental formula for the dog
permanent=42
2(I3/3, C1/1, P4/4, M2/3)
decid= same except only 3P and noM
dental formula for the cat
permanent= 30
2(I3/3, C1/1, P3/2, M1/1)
decid= same except no M
which teeth are used for tearing?
canines and premolars
what is the true shearing teeth?
carnassial-
dog=4th upper PM and lower 1st M.
cats= 4th upper PM and lower molar
what are the bones of the face?
incisive-upper incisors
maxilla-upper canine and cheek teeth
palatine-hard palate
mandible-all of lower teeth
what are the nerves of the mouth?
trigeminal nerve=5th cranial nerve, chewing.
hypoglossal nerve-tongue
what is the pH of saliva?
7.5-promotes plaque
where are salivary glands?
parotid-upper P4
sublingual-lingual to lower cheek teeth
zygomatic-lateral to M2
where is the heaviest calculus
buccal surface upper cheek and canines
lingual surface of lower teeth
buccal surface of lower cheek teeth
palatal surface of upper cheek teeth
what is another name for the cervical line?
CEJ- cemento-enamel junction
what is the triadan numbering system?
mouth has 4 quadrants- 1 is upper R, 2 upper L,3 is lowerL, 4 lower R-every #ending with 4 is a canine, every # ending with 9 is a 1st molar.
how many molars does the dog have?
2 on top, 3 on bottom
how many molars does the cat have?
