- radiation caries & periodontal disease
- infections (ie candidiasis)
- loss of taste
- dysphagia
- osteoradionecrosis

2

what are the aims of local treatment?

protect local area
relieve pain
reduce inflammation
OR
control secondary infection

3

define mucositis?

inflammation of the mucosa

4

what will mucositis look like?

white/yellow fibrinous slough often with ulceration & bleeding

unpleasant odour

5

what will patient complain about with mucositis?

painful to eat, speak and swallow

inability to tolerate prosthesis

6

is mucositis a portal for microbial entry?

yes

7

when is mucositis likely to heal completely?

2-3 weeks post completion cancer therapy

8

how to manage mucositis? 8 points

- SOFT toothbrush with F toothpaste
- chlorhexidine mouthwash if toothbrush comprimised
- hydrogen peroxide dilute mouthwash for short term
- gauze or sponge application of mouthwash
- topical analgesics or anti-inflammatory rinses, gels or ointments may be applied prior to eating
- soft, bland non-cariogenic diet at low temperature is advised
- alcohol and tobacco must be avoided

9

how many days after the beginning of treatment would you expect a reduction in serous gland production?

3-4 days

10

what does this reduction in serous gland production lead to?

- increased susceptibility to candidal/viral infections
- increased risk of demineralisation
- mastication and swallowing impaired
- dry friable mucosa (difficulty in tolerating prosthesis)

11

what is the oral management of xerostomia?

- pilocarpine therapy
- saliva substitutes (preferably with fluoride)
- water atomiser and ice chips can be soothing
- avoid dry foods and sucking on sugary sweets
- chewing sugar free gum
- humidifiers

12

where will radiation caries occur mostly?

on exposed root surfaces

13

where do these radiation caries lesions spread to?

will encircle the neck of the teeth

14

is radiation caries directly related to radiation?

no, still multifactorial

15

oral management of radiation caries?

Intensify prevention measures
- daily fluoride application m/w or 2800ppm TP
- non-cariogenic diet
- saliva substitute

16

name two anti-fungal treatments?

- niconazole (spray or tablet)
- daktarin gel
