Q

What is radiotherapy?

Study These Flashcards
A

The use of ionising radiation to treat diseases

23
Q

What is ionising radiation?

Study These Flashcards
A

Refers to type of radiation in which absorption of energy results in ejection of one or more orbital electrons from an atom or molecule

24
Q

What is the aim of radiation to treat cancer?

Study These Flashcards
A
  • Irreparably damage double-stranded DNA

- Cause this directly or indirectly

25

26
Name 5 complications of bone metastases
1. Bone marrow failure 2. Pain 3. Fractures 4. Spinal cord compression 5. Hypercalcaemia
27

1. Risk of infection 2. Risk of bleeding 3. Stomatitis 4. Xerostomia 5. Dysgeusia 6. Mandibular osteonecrosis
28
What must happen with regards to oral health prior to radiation or chemotherapy?
Teeth which are non-restorable or potential problem teeth should be removed and all other teeth restored to optimum health
29
Name 4 main dental problems of radiotherapy
1. Xerostomia 2. Mucositis 3. Taste alterations 4. Radiation caries and osteoradionecrosis
30
Name 5 ways to manage dental health for a patient receiving radiotherapy

32
What is the major side effect of all oncology mediations?
Stomatitis
33
Name 2 treatments used for invasive procedures with regards to cancer
1. Antibiotic prophylaxis | 2. Platelet replacement
34
What is the characterisation of osteonecrosis of the jaw?
- Exposed necrotic bone - Pain - Local swelling
35
Explain why there is more cases of osteonecrosis of the jaw in females
Hormone therapy and bisphosphonate treatment use is higher in females
36
Name 2 types of anti resorptive agents which cause jaw osteonecrosis
1. Bisphosphonates (alendronate, zoledronate) | 2. Rank ligand inhibitor (denosumab)
37
Name 3 agents which are not anti resorptive which can cause jaw osteonecrosis
1. Antiangiogenic agents (sorafenib) 2. Phosphorus 3. Irradiation
38
Describe the mode of action of bisphosphonates
- Stable derivatives of inorganic pyrophosphate - Bind hydroxyapatite crystals - Incorporated in sites of active remodelling - Prevent resorption by osteoclasts - Promote osteoclast apoptosis
39
Describe the mode of action of denosumab
- Human monoclonal antibody to receptor activator of nuclear factor kappa B - Inhibits development and activation of osteoclasts - No binding to bone matrix - Anti resorptive effects dissipated
40
Describe 3 components of the management of dental disease in established osteonecrosis
1. Conservative treatment of teeth 2. Necrotic symptomatic bone should be removed 3. Extract symptomatic teeth in necrotic bone
41
With regards to oncology, name 3 patients dentists must be particularly cautious with
1. Patients receiving chemotherapy 2. Patients on bone targeted therapies 3. Patients receiving or having received radiotherapy to head and neck region
