|
|
Term
|
Definition

3) Gingiva (free and attached) |
|
|
Term
| What is the periodontal ligament? What is it made of? |
|
Definition
| Holds the tooth in the bone socket(alveolus) and connects the tooth root and bone. Made of collagen and elastic fibers. |
|
|
Term
| What is the Alveolar bone? What is it a part of? |
|
Definition
| It forms the bone socket that holds the tooth root. It is part of the mandible or maxilla. |
|
|
Term
| What is the gingiva? What is it made of? |
|
Definition
| The "gum" tissue that attaches to the tooth at the cement-enamel junction. It is thick heavily keratinized tissue. |
|
|
Term
| What is alveolar mucosa? What is it made of? |
|
Definition
| Remaining oral mucosa covering the mandible and maxilla. Made of thin, non-keratinzed mucosa that is very mobile. |

Term
| What are the 6 normal occulusion in dog? |
|
Definition
1) maxillary incisors are rostral to mandibular incisors (scissor bite)
2) Mandibular canine interdigitates between the maxillary corner incisor and canine, touching neither tooth (dental interlock)
3) mandibular P1 rostral to maxillary P1. Cusps of premolars oppose the opposite interdental space of the opposite arch (pinking shear effect) and the maxillary P4 covers mandibular M1.
4) premolar horizontal relationship (freeway space reatively even and parallel)
5) crowns of maxillary and mandibular molars occlude with each other
6) head symmetry |

Term
| What is tooth abrasian vs. tooth attrition? |
|
Definition
Abrasian- tooth substance loss from physiological forces.
Attrition- tooth substance loss from tooth/tooth contact |
|
|
Term
| What are the 8 steps to dental cleaning? |
|
Definition
1) Physical and oral exam (soft and hard tissues)
2) General anesthesia, intubation
3) Scaling
4) Polishing
5) In-depth oral exam
6) Periodontal probing
7) Charting
8) Check to be sure oral cavity empty |
