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 |
