Q

What is tertiary dentine?

A

reactive dentine that is laid down in response to irritation or damage in the tooth

24
Q

What are age related changes to the pulp?

A

reduction in the size of pulp chamber and root canals, decrease in cellular elements, decrease in vascularity and sensitivity

25
Q

What are age related changes to cementum?

A

increase in amount as cementogenesis continues throughout life

26
Q

Do healthy human teeth become more or less mobile with age?

A

less

27
Q

What are age related changes to the PDL?

A

more fibrotic, less elastic, PDL space narrowing

28
Q

How is alveolar bone maintained in the mouth?

A

in the presence of teeth

29
Q

What is the average life span of osteocytes?

A

35 years

30
Q

What are the consequences of elderly bones containing increased numbers of dead osteocytes?

A

mineralisation of lacunae, brittle and sclerotic bone

31
Q

When do females begin bone calcium loss?

A

40-45

32
Q

When do males begin bone calcium loss?

A

60

33
Q

What is gerodontology?

A

the branch of dentistry that deals with ageing and older people

34
Q

Do we use chronological age to determine who is elderly?

A

no, biological age is more important

35
Q

Why is Gerodontology becoming more relevant?

A

people are living longer and keeping their teeth longer

36
Q

What changes can you expect in the mouth of an ageing patient?

A

tooth wear, recession, xerostomia, root caries, increased oral cancer risk

37
Q

Why does oral health and the ageing patient matter?

A

good oral health can have a positive impact on general well-being and quality of life, unsatisfactory dentition or dentures can lead to social isolation due to wishing to avoid eating with others, if they have reduced chewing efficiency it may lead to malnourishment

38
Q

What are some links between oral health and general health?

A

oral bacteria have been linked to chest infections, the severity of periodontal inflammation is linked to glycaemic control with diabetes

39
Q

What are some ways retaining the natural teeth can have a benefit on life?

A

diet, nutrition and quality of life

40
Q

What are some barriers to oral health care in the elderly?

A

mobility, illness, inconvenience, cost, lack of access to NHS care, fear, anxiety, professional barriers

41
Q

Why can mobility be a barrier to oral health care in the elderly?

A

can be difficult for them to get to the surgery, patients may find it difficult to get upstairs

42
Q

Why can cost be a barrier to oral health care in the elderly?

A

there can be lots of costs associated with going to the dentist and many patients will likely be embarrassed by not being able to afford treatment or be scared of the costs

43
Q

Why can fear of the dentist be a barrier to oral health care in the elderly?

A

fear of the dentist is common among the elderly due to previous personal bad experiences and negative perceptions of dental treatment

44
Q

Why can availability of dental services be a barrier to oral health care in the elderly?

A

there seems to be difficulty in finding an NHS dentist and can be limited information on dental services in different languages

45
Q

What are root caries?

A

caries on the root surface after it has been exposed due to recession

46
Q

What are some risk factors for root caries?

A

high sugar diet, dry mouth, partial dentures

47
Q

How can you prevent root caries?

A

OHI, diet advice, fluoride

48
Q

Is periodontitis more common in the elderly?

A

no

49
Q

What are some potential causes of xerostomia?

A

side effect of medications, radiotherapy to head and neck, diabetes, sjogren’s

50
Q

What side effects can occur due to xerostomia?

A

increased caries risk, perio disease, candida infections, dysphagia, difficulty tolerating dentures

51
Q

How can you manage xerostomia?

A

regular sips of water, sugar free gum, saliva substitutes

52
Q

What percentage of 75-84 year olds have tooth wear?

A

95%

53
Q

What may be some presenting complaints associated with toothwear?

A

sensitivity, sharp teeth, pulpitis, aesthetic concerns

54
Q

Is the treatment plan for toothwear always the same?

A

no, it depends upon the severity of the toothwear

55
Q

What are the important points for denture hygiene?

A

remove dentures at night, brush dentures with soap and water, place denture in water overnight, brush teeth if present, remove dentures and clean them during the day if food gets stuck

56
Q

What percentage of stroke survivors require special support?

A

50%

57
Q

How can a stroke affect how well a denture is tolerated?

A

reduced muscle control can reduce the retention, trouble inserting and removing dentures
