Q

What is tooth resorption?

A
  • Progressive destruction of hard dental tissue by odontoclast cells, replaced with granulation tissue
  • Odontoclast cells responsible for repair, remodelling or destruction

Q

How are type 2 tooth resorption lesions managed?

A
  • If there is partial replacement resorption then must remove the remaining root and associated pulp via surgical extraction.
  • If the root is fully resorbed then a subgingival crown coronectomy is performed

Q

Describe the perfect candidate for a subgingival crown coronectomy for Type 2 TR

A
  • Advanced type 2 TR confirmed via x-ray
  • Lack of periodontal ligament structure
  • No recognisable root canal structure
  • No periapical pathology

Q

Describe the crown amputation technique

A
  • Create envelope flap to access cementoenamel junction
  • Using a fine round burr cut along the long axis of the crown
  • Aim is to remove all of the tooth structure just below the level of the alveolus
  • Then smooth the edges via alveolectomy
  • Then close the gingival opening with no tension

Q

What is never a treatment option for resorptive lesions and why?

A

Root atomisation

  • High speed burr can cause excessive damage to the underlying alveolar bone
  • Extremely painful and unnecessary

Q

What are some clinical signs of feline chronic gingivostomatitis?

A
  • Severe inflammation at the back of the mouth (bright red)
  • Ulceration
  • Gingival hyperplasia
  • Screaming when eating
  • Dysphagia
  • Halitosis
  • Poor coat quality
  • Weight loss
17
Q

How is feline chronic gingivostomatitis assessed and investigated?

A
  • Thorough clinical exam and client history
  • Full blood work and immune status
  • Dental radiography
  • Through PCR swab for calicivirus and FHV
  • Biopsy if not bilateral
18
Q

What are the aims of treatment for feline chronic gingivostomatitis?

A
  • Reduce the burden of oral antigen in the cat’s mouth long term
  • Improve the welfare of the patient by considerably reducing their pain
  • Reduce inflammation of the oral soft tissues
19
Q

What must owners be informed of when treating feline chronic gingivostomatitis?

A

That an absolute resolution ‘back to normal’ may be difficult to achieve

20
Q

How is feline chronic gingivostomatitis treated?

A

Surgical treatment is a priority over medical

  • Full mouth dental radiographs
  • Full scale and polish
  • Removal of any diseased teeth/roots -> Full mouth extractions (all PM’s and M’s) -> Full moth extractions (canines and incisors)
21
Q

How can feline chronic gingivostomatitis be medically managed?

A
  • Pain relief
  • Antibiotic therapy
  • Plaque reduction
  • Feline recombinant interferon omega
  • Dietary supplementation
  • Steroids
  • Food bowls
22
Q

Which drugs are used for pain relief in cats with feline chronic gingivostomatitis?

A
  • NSAIDs (meloxicam)
  • Buprenorphine (sub-lingual)
  • Gabapentin (tablet)
23
Q

Which drugs can be used for antibiotic therapy to treat feline chronic gingivostomatitis?

A
  • Amoxicillin-calvulanate (Synulox drops)

- Clindamycin tablets

24
Q

How can plaque be reduced in the mouth using medical management?

A
  • Hexarinse mouth rinsing or Dentisept

- Teeth brushing daily

25
Q

When is feline recombinant interferon omega used?

A
  • Excellent in cats that are non-responders to surgical extraction and are calicivirus positive
  • Helps decrease the need for anti-inflammatory treatments
26
Q

Why are food bowls involved in medical management?

A
  • Ceramic food bowls harbour less bacteria
  • Less likely to cause a hypersensitivity reaction
  • Plastic or metal should be removed
