Small Animal Dentistry
* Goals of veterinary dentistry: infection free oral cavity, pain free oral cavity, be a patient advocate
* Dental Formula – Dogs and Cats are diphyodont (have primary dentition and adult dentition)
* Dog:
* Deciduous: I3/3, C1/1, P3/3 = 28
* Permanent: I3/3, C1/1, P4/4, M2/3 = 42
* Cat:
* Deciduous: I3/3, C1/1, P3/2 = 26
* Permanent: I3/3, P3/2, M1/1 = 30
* "Strategic teeth" = canines, maxillary 4th premolars, mandibular 1st molar
* 4 tissues of the periodontium = gingiva, alveolar bone, periodontal ligament, cementum
* Gingiva – protects the subgingival periodontium
* Gingival crevicular fluid – outward flow that flushes, is antimicrobial, has immunoglobulins and plasma proteins.
* PDL:
* Functions: anchor, shock absorber, periodontal maintenance
* Cells: epithelial rests of malassez, immune cells, neurovascular cells, connective tissue cells (predominant cell is the fibroblast) – collagen synthesis, phagocytic capacity.
* Note: the primary cell in the pulp that produces dentin is the odontoblast.
* Nomenclature:
* Modified triadan system
* 4’s = canines
* 9’s = first molars
* permanent teeth: upper right = 100’s, upper left = 200’s, lower left = 300’s, lower right = 400’s.
* deciduous teeth: 500, 600, 700, 700 quadrants
* Intraoral Radiographs:
* Labeling:
* RIGHT LEFT
* RIGHT LEFT
* **If the canine is to your left, it is the left quadrant. If the canine is to your right, it is the right quadrant.
* Normal hard tissues = cups of tooth, enamel, secondary dentin, cementum (cannot see radiographically).
* Normal periodontal structures = cementoenamel junction, alveolar marginal bone, PDL space (lamina lucida), lamina dura, interradicular bone in furcation region, interproximal alveolar bone, ventral cortical bone....
