Q

Q

Why is it important to remove hyperdont (supernumerary) teeth?

A

Hyperdont teeth increase the surface area for plaque and calculus to accumulate which increases the risk of periodontal disease, and they can result in class I malocclusion so it is important for them to be removed

Important to note that that hyperdontia has a good prognosis

41
What is gingivitis?
Gingivitis is reversible inflammation of the gingiva
42
What is periodontitis?
Periodontitis is an irreversible state of disease which affects the gingiva, alveolar bone and the periodontal ligament. Some of the clinical signs of periodontitis include pockets between the teeth and gums, halitosis, loose teeth etc. | One of the most common dental diseases in veterinary medicine
43
What can periodontitis progress to?
Oronasal fistulas and rhinitis | Sometimes sneezing can indicate oronasal fistula and rhinitis due to periodontal disease
44
Which breed of dog is particularly prone to oronasal fistulas secondary to periodontitis?
Dachshunds
45
What should you do if you identify periodontitis on clinical examination?
If you identify periodontitis on clinical examination, you should do a full oral examination and dental radiography to establish the extent of the disease
46
How do you treat periodontitis?
Periodontitis is treated with tooth extractions
47
What is one of the most common forms of dental disease in cats?
Tooth resorption
48
Identify this type of tooth resorption
Type I tooth resorption
49
What is a key sign of type I tooth resorption?
A red dot on the clinical crown is a key sign of type I tooth resorption
50
What triggers type I tooth resorption?
Inflammation (such as periodontal disease)
51
Which disease is type I tooth resorption most commonly associated with?
Periodontal disease
52
Identify this type of tooth resorption
Type II tooth resorption
53
What triggers type II tooth resorption?
Type II tooth resorption is idiopathic
54
How do you diagnose type II tooth resorption?
You can diagnose type II tooth resorption with dental radiography
55
Identify this type of tooth resorption
Type III tooth resorption
56
Which teeth are most commonly affected by tooth resorption?
Mandibular third premolars followed by the first molars
57
Which type of tooth resorption always requires treatment?
Type I tooth resorption always requires treatment
58
How do you treat type I tooth resorption?
Type I tooth resorption is treated with tooth extraction
59
Identify this classification of tooth trauma
Enamel infraction - microcracks in the enamel of the tooth

Identify this classification of tooth trauma
Enamel fracture
62

Uncomplicated crown fracture - fracture involving the enamel and dentin
63
How does the tooth respond to uncomplicated crown fractures?
In response to uncomplicated crown fractures, the tooth will produce tertiary dentin to protect the dental pulp from invading microorganisms

What is stomatitis?
Stomatitis is inflammation of the oral soft tissue structures and mucosa
81
How do you often have to treat stomatitis?
Tooth extraction as stomatitis can be caused by an immune response against plaque and calculus that accumulates on the teeth. Stomatitis is very challenging to treat and requires referral
82
What should you do as further investigation in dogs that present with oral inflammation?
In dogs that present with oral inflammation, you should take a biopsy of the mouth to determine if the inflammation is secondary to neoplasia or stomatitis
83
What is an oronasal fistula?
An oronasal fistula is an abnormal connection between the oral and nasal cavities
84
What are the differential diagnoses for causes of oronasal fistulas?
Periodontal disease Malocclusion Foreign bodies Neoplasia Tooth extraction
85
How can a tooth extraction cause an oronasal fistula?
Tooth extractions without a mucogingival flap will result in an oronasal fistula
86
How do you treat an oronasal fistula?
An oronasal fistula requires sugical correction and will often require referral
87
What should you always do before taking a biopsy of oral masses?
Take a photograph of the mass and describe it in detail before taking a biopsy
88
(T/F) Oral masses in cats are more commonly malignant neoplasia than oral masses in dogs
TRUE.
89
What is the most common differential diagnosis for an oral mass in cats?
