- Home care- products, methods
- Treats
- Toys
- Bad habits

what is the most common oral disease in cats and dogs
periodontal disease
how many teeth do dogs have
42
what is largest maxillary and mandible tooth in dogs
maxillary- PM4
Mandible- M1
how many teeth do cats have
30
what species, identify 307-308
Cat
307-308: premolars
309; molar
what is class 0 occlusion
normal
what is class 1 occlusion
normal length of maxilla and mandible but malposition of one or more individual teeth
what is class 2 occlusion
shorter mandible
what is class 3 occlusion
longer mandible
what class occlusion
Class 0- normal
what class occlusion is this
class 1- normal jaw length, malposition of one or more teeth
what wrong and what class occlusion
retained deciduous teeth- causing linguoversion
Class 1 occlusion
what class occlusion is this
Class 2- shorter mandible- canine teeth hit palate instead of diastema
what malocclusion is this
class 3- longer mandible
what malocclusion is maxillary-mandibular asymmetry
skeletal malocclusions Rostro-caudal, side to side or dorsal-ventral
Unequal jaw lengths
what type of malocclusion is this and what wrong
maxillary mandibular asymmetry: left mandible longer than right
what wrong
Retained deciduous teeth
what type of staining is this and can it be removed or not
extrinsic staining- can be removed
what type of staining is this and what wrong
Instrinsic staining- purple.grey/yellow/brown
X-ray large pulp cavities- pulpitis- dead teeth
what wrong, which x-ray normal vs abnormal
pulpitis
Left: normal
Right: dead pulp- large canal
what is typically cause of pulpitis
concussive damage
what is tx for pulpitis
root canal or extraction
what this and what does it do
dental explorer- shepherds hook on one end and probe on other
Shepherds hook feels for lesions
what wrong
Pulp exposure
what wrong
reparative dentin- not pulp exposure
what wrong and what tx
pulp exposure- extraction or root canal
define abrasion
pathological wearing away of dental substance through abnormal mechanical process- chewing on object
define attrition
tooth on tooth wearing typically due to malocclusion
what this
cavity- Rare
what wrong
dens invaginatus- congenital
what wrong
tooth resorption
what wrong
mild gingivitis
what wrong
severe gingivitis
what wrong
stomatitis, caudal mucositis
what is gingivitis
inflammation of gingiva typically with bleeding
what is periodontitis
bone loss
what is stage 0 mobility
physiological mobility up to 0.2mm
what is stage 1 mobility
mobility is increased in any direction other than axial >than 0.2mm and up to 0.5mm
what is grade 2 mobility
mobility is increased in any direction other than axial over a distance of >0.5mm to 1.0mm
what is grade 3 mobility
mobility is increased in any direction exceeding 1.0mm or any axial movement
what type of bone loss
left: horizontal bone loss
Right: vertical bone loss
what wrong and how do you measure
Gingival recession (root exposure)
Measure from CEJ to gingival margin
what wrong
Furcation involvement- class 3
what is Furcation involvement class 1
probe enters, but bone still fills most of area between roots, arch of tooth structure can be felt, probe only penetrate about 1mm
what is Furcation involvement class 2
probe will penetrate more than 1mm but not completely through
what is Furcation involvement class 3
through and through passage, no bone within arch of Furcation
what wrong
Periodontitis- gingival recession and alveolar bone loss
what wrong
advanced periodontitis
what wrong
Chronic ulcerative mucositis/ contract ulcers “kissing lesions”
Lips having reaction to plaque on teeth
what is the #1 oral neoplasia of cats
SCC
what is number one oral neoplasia of dogs
melanoma
what wrong
odontogenic fibroma
What wrong
acanthomatous ameloblastoma
what wrong
gingival enlargement
what are some causes of gingival enlargement
- Inflammatory
- Drugs- cyclosporine, Ca2+ channel blockers, anticonvulsants
- Associated with pregnancy or puberty
- Neoplastic
- False enlargement
what is tx for gingival enlargement
- Stop offending drug
- Gingivectomy/ ginvioplasty, biopsy
- Oral hygiene
cat- what is arrow pointing at
lingual molar gland
what is lingual molar gland
mixed salivary gland on lingual aspect of the mandibular 1st molar in cats
what Circled
Incisive papilla
