Intro To Dentistry Flashcards
Which surface of the tooth is toward the midline of the dental arch?
Mesial
What type of teeth in cats and dogs have no deciduous component?
Molars
Any carnivore that has less than ___ teeth is considered to be missing premolars from the front and molars from the back.
42
Landmarks: What number is the canine tooth?
04
What number tooth is the first molar?
09
What are the potential problems retained deciduous teeth predispose a patient to?
Orthodontic (malocclusions) and periodontal problems (alveolar periostitis, premature loss of teeth, and dental calculus)
What is the only tooth whose permanent form erupts rostrally in relation to the deciduous tooth (as opposed to typical lingual eruption)?
Canine tooth
What is interceptive orthodontics?
An alternative to orthodontic movement, major occlusions may need to be extracted or have their crown height reduced {to prevent trauma to other teeth/soft tissue structures in mouth}
if noted early enough, primary teeth may be extracted to prevent dental interlock so small differences in growth rates of the upper & lower jaw may correct over time..
What is the most common problem we see that requires orthodontics?
*Base Narrow Canines (class 1 malocclusion)*
What do dentigerous cysts result from?
Persistence of portions the enamel forming epithelium—> this creates a fluid-filled cyst surrounding the crown of an unerupted tooth
High fevers, Distemper, periapical inflammation, or trauma of the permanent tooth bud, endocrine dysfunction early in life can all lead to …..?
Enamel hypoplasia/Hypocalcification
Term for draining tract associated with the teeth?
Parulis
Which teeth are considered the carnassial (largest teeth in the mouth) in all carnivores?
The 4th maxillary premolar & the 1st mandibular molar
*sharp overlapping edges*
When does apical closure occur?
About 18 months of age
pulp canal becomes progressively smaller w/age while the dentin thickens w/age…

When do deciduous canines erupt in the cat vs. dog?
Cat: 3-4 weeks old

Dogs:4-12 weeks old
When do permanent premolars erupt in the cat vs. dog?
Both 4-6 months old!
When do permanent molars erupt in the cat vs. dog?
Cat: 4-5 months old
Dog: 5-7 months old

What is the most commonly fractured tooth in dogs?
Upper fourth premolar
(108 and 208)
Mandibular adult canines will erupt ____ to deciduous canines.
Lingual
What number tooth is the right maxillary middle incisor?
102
What number tooth is the right mandibular 1st molar in the dog?
409
What number tooth is the left mandibular 4th premolar in the dog?
308
What type of resorptive tooth lesion is this? What’s the most appropriate treatment?
note fractured mesial root tip
Type 1:
presence of periodontitis w/horizontal bone loss
although it will be difficult, extraction of this tooth is indicated
What treatment is indicated for this?
Incline Plane w/ Maxi-Temp (non-exothermic bis-acrylic)
buuut. .. alternate technique typically used if possible bc incline plane can cause trauma upon removal:
* *pain relievers,**
de-caf green tea rinses,
tincture of time
What is this & how do we treat it?
Attrition
{pathological wearing d/t contact w/opposing tooth}
treat w/orthodontic correction, crown reduction, or extraction
- What tool is pictured?
- What dental disease is present?
3. How do we treat?
- Dental explorer
- Abrasion {caused by abnormal contact w/crown surface by foreign object}
-
Extract or perform root canal
{pulp is exposed in this case so game over…}
What drugs can cause this disease?
Cyclosporine,
Calcium channel blockers,
Anticonvulsants
Treat by removing excessive tissue to return sulcus depth to normal
What 3 disease processes are implicated in the formation of Periodontal Disease?
- Chronic nephritis
- Hepatopathies
- Endocarditis
What type of resorptive tooth lesion is pictured? How would we treat?
Type 2:
note root replacement resorption & ankylosis of mandibular canines…
Treat w/crown amputation since there is no evidence of periodontal disease
What disease is pictured & how do we differentiate it from regular periodontal disease?
Gingivostomatitis aka Lymphocytic Plastmacytic Gingivostomatitis (LPGS)
this disease is limited typically to the caudal part of the mouth (caudal stomatitis);
**maxillary teeth caudal to canines most commonly affected…
*treatment includes extraction, cyclosporine, & top home care**
Cat presents on emergency for episodes of severe oral bleeding…
What vessel needs to be ligated to resolve this?
Eosinophilic granuloma
ligate the Greater Palatine artery that lives in this area…
What even are base narrow canines??
Lingually displaced mandibular canines caused by too narrow of a mandible or persistent primary mandibular canines (retained deciduous teeth)
What type of suture should we use for gingiva? Spacing??
Absorbable 3-0 to 5-0
Vicryl Rapide (polyglactin 910)
every 2-4mm
