| 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 |
