Question Answer
crown tooth above the gum line
root tooth below the gum line
neck narrowing of tooth at the gum line
enamel hardest tissue in body protects interior of tooth from external oral environment
dentine 2nd hardest tissue in body makes up most of the crown & root shock absorber sensory function - thermal or chemical stimuli
cementum covers the root point of attachment for periodontal ligament protects dentin
pulp cavity contains soft tissue of the tooth odontoblasts, arterioles, venules, sensory nerves, lymphatics and connective tissue
apex or apical delta where blood vessels, nerves and lymphatics enter the pulp cavity
periodontal ligament attaches cementum to alveolar bone shock absorber; helps dissipate occlusal forces
alveolus bony socket that surrounds the root
gingiva gum tissue protects bone and tooth attachment from infection and trauma
furcation space between the roots of a multi-rooted tooth
apical toward the root
coronal toward the crown
cervical toward the neck junction of the coronal and apical tooth
mesial toward the midline of dental arch
distal away from the midline of dental arch
rostral toward the front of head
caudal toward the back of head
buccal surface facing the cheeks
facial or labial surface facing the front lips
lingual surface facing the tongue - mandible
palatal surface facing the hard palate - maxilla
sublingual surface beneath the tongue
primary dentine forms before tooth eruption
secondary dentine forms after tooth eruption
tertiary (reparative) dentine forms as a result of trauma to the odontoblasts
interproximal space space between adjacent teeth
interproximal surface the adjacent surfaces of 2 adjoining teeth
incisal biting surface of incisors
occlusal grinding surface of molars
brachyodont primates, carnivores, pigs apex closes after eruption & tooth growth small crown relative to root
hypsodont equine, lagomorph, rodent apex remains open through most or all of adult life - continued tooth growth
diphyodont animals (most mammals) having 2 sets of teeth - deciduous & permanent
dog formula - deciduous 2 (I 3/3, C 1/1, P 3/3) = 28
cat formula - deciduous 2 (I 3/3, C 1/1, P 3/2) = 26
dog formula - permanent 2 (I 3/3, C 1/1, P 4/4, M 2/3) = 42
cat formula - permanent 2 (I 3/3, C 1/1, P 3/2, M 1/1) = 30
carnassial teeth shearing teeth last maxillary premolar 1st mandibular molar
what teeth are missing in a cat's mouth Maxillary P1 – 105 and 205 Maxillary M2 – 110 and 210 Mandibular P1 – 305 and 405 Mandibular P2 – 306 and 406 Mandibular M2 – 310 and 410 Mandibular M3 – 311 and 411
