Q

what is chronic periodontitis

A

Characterised by the destruction of the junctional epithelium and connective tissue attachment of the tooth, together with bone destruction and formation of periodontal pockets.

The disease progresses slowly and the amount of bone loss tends to reflect the age of the patient over time

Q

What is aggressive periodontitis

A

A severe condition usually found in a younger cohort of patients, which may be associated with a familial history of aggressive periodontitis.

Disease progression is rapid and the degree of destruction of the connective tissue attachment and bone is severe, considering the age of the patient.

Plaque levels may be inconsistent with the level of disease seen

A

through hands on demonstrations. Remember consent is required

36
Q

What should you talk about with the patient

A

Talk with the patient about the causes of periodontal disease and why good oral hygiene is important.

Talk with the patient about what he/she has to do to achieve good plaque removal.

37
Q

What can be used when describing the causes of periodontal disease

A

Use of a visual aid may help patients understand the disease process and the effects of plaque on the periodontal tissues.

38
Q

What do you say to patients when talking about what they have to do to achieve good plaque removal

A

Brush regularly using an effective technique.
Use a fluoride-containing toothpaste and ‘spit don’t rinse’ during tooth cleaning.
Clean interdentally once a day.

39
Q

What should the manual and toothbrush heads be like

A

should be small and of a medium texture and should be changed when obvious signs of wear appear.

40
Q

What toothpastes are more effective at reducing plaque

A

triclosan and a co- polymer

41
Q

How should the interdental brush fit

A

snugly into the interdental space without the wire rubbing against the tooth.

42
Q

How should you instruct

A

Instruct the patient in the use of the oral hygiene tools.
Demonstrate, in the patient’s mouth while he/she holds a mirror, how to systematically clean each tooth using a toothbrush (manual or rechargeable powered) as well as how to use
floss and/or interdental brushes.
Confirm that the patient knows what to do. If he/she does not, show the patient again.

43
Q

What should you do in practice

A

Ask the patient to practise i.e. to clean his/her teeth in front of you
Ask the patient for some feedback.

44
Q

why should you ask the patient to practice infront of you

A
  • This provides an opportunity to correct the patient’s technique if required and ensures that the patient has really understood what he/she needs to do.
  • Confirming that the patient is doing the task well will boost confidence and also help him/ her to remember when at home.
45
Q

why should you ask the patient for some feedback

A

Ask how his/her teeth feel, as clean teeth should feel smooth to the tongue.
• Address any concerns the patient has if there is bleeding after brushing or interdental cleaning.

46
Q

what should you do in the plan

A

Help the patient plan how to make effective plaque removal a habit.
To act as an incentive for the patient, tell him/her that you will ask at the next visit

47
Q

how can you help the patient make effective plaque removal a habit

A

Ask the patient when would be the best time for him/her to brush and clean interdentally. Suggest using another regular activity as a reminder – such as immediately before going to bed and after getting up.

48
Q

what should you ask the patient at the enter visit

A

• “Have you tried using interdental cleaning aids?” • “How did your action plan work?”

49
Q

How should you support the patient

A

Ensure you support the patient to achieve effective plaque removal by following-up on the advice at subsequent appointments.

50
Q

How should you go about helping a patient to quit smoking

A

Ask the patient if he/she (still) smokes (or uses smokeless tobacco) and record the response
Ask if the patient has considered the effect smoking has on his/her oral health and general health and the benefits of stopping.
Ask if the patient is interested in stopping smoking.
Offer patients who are interested in stopping smoking information on local smoking cessation services as these increase their chances of a successful quit attempt.

51
Q

what should you say if the patient states they have given up smoking

A

If the patient states that he/she has given up, congratulate this achievement. Remind the patient that stop smoking services are always available if he/she is finding it difficult to remain a non-smoker.

52
Q

what should you do if patient does not wish to stop smoking

A

Some patients may not wish to stop smoking; accept this in a non-judgemental way, but leave the offer of future help open if the patient changes his/her mind.

53
Q

what should you say regarding other lifestyle factors

A

Evidence that a high sugar diet is a risk factor for dental caries and that a high level of alcohol consumption is a risk factor for cancer of the mouth, larynx, pharynx and oesophagus as well as many other chronic diseases.
Emerging evidence also suggests that diet, obesity and level of physical activity are associated with periodontitis and that diet may influence the outcome of periodontal therapy.

54
Q

what are the key recommendations in regard to the treatment of gingival conditions

A
  • Ensure the patient is able to perform optimal plaque removal
  • Remove supra gingival plaque, calculus and stain and sub-gingival deposits
  • Ensure that local plaque retentive factors are corrected
55
Q

what is plaque induced gingivitis

A

Gingivitis is plaque induced inflammation of the gingivae characterized by red swollen tissues that bleed on brushing or probing.

56
Q

what is gingivitis not associated with

A

with apical migration of the junctional epithelium or connective tissue attachment loss and alveolar bone destruction.

57
Q

when re clinical signs visible

A

after around seven days of undisturbed plaque accumulation and the severity of the inflammatory response is greater in older people than in the young. The condition is reversible after the establishment of effective plaque removal.

58
Q

What should you say to patients regarding gingivitis

A

Explain to the patient that untreated gingivitis is a risk factor for periodontitis, which can lead to tooth loss, but that he/she can reduce this risk with good oral hygiene.
Remove supra-gingival plaque, calculus and stain and sub-gingival deposits using an appropriate method
Ensure that local plaque retentive factors are corrected
Re-assess at a future visit to determine whether the gingivitis has resolved.

59
Q

what should you do for patients regarding drug induced enlargement

A

Where there is mild gingival enlargement, use the Oral Hygiene TIPPS
Remove supra-gingival plaque, calculus and stain and sub-gingival deposits using an appropriate method. Highlight to the patient the areas where supra- gingival deposits are detected.
Ensure that local plaque retentive factors are corrected
Where the gingival enlargement hinders adequate plaque removal or interferes with the normal function of the oral cavity, consider consulting the patient’s physician or referring for specialist periodontal care.

60
Q

What is pregnancy-associated ginvitis

A

The changes in hormone levels and to the immune response associated with pregnancy have been implicated in the development or worsening of gingivitis.

61
Q

how should you deal with pregnancy associated gingivitis that is mild

A

Where the condition is mild, use the Oral Hygiene TIPPS behaviour change strategy to highlight the importance of effective plaque removal and to show the patient how she can achieve this
Ensure that local plaque retentive factors are corrected - for example, remove overhanging restorations or alter denture design
Explain to the patient that the condition is likely to resolve once her baby is born or following the cessation of breastfeeding, assuming her oral hygiene is adequate.

62
Q

how should you deal with pregnancy associated gingivitis that is severe

A

Give oral hygiene and smoking cessation advice as detailed above. Remove supra-gingival plaque, calculus and stain and sub-gingival deposits using
an appropriate method. Highlight to the patient areas where supra- gingival deposits are detected. These patients may require more frequent recall visits during pregnancy and additional care.
Ensure that local plaque retentive factors are corrected - for example, remove overhanging restorations or alter denture design
Explain to the patient that the condition is likely to resolve once her baby is born or following the cessation of breastfeeding, assuming her oral hygiene is adequate

63
Q

What is puberty associated gingivitis

A

Gingivitis is commonly observed in pre-teens and young teenagers where the increased inflammatory response to plaque is thought to be aggravated by the hormonal changes associated with puberty

64
Q

how should you deal with those that have puberty associated gingivitis

A

use the Oral Hygiene TIPPS behaviour change strategy to highlight the importance of effective plaque removal and to show the patient how he/she can achieve this
Remove supra-gingival plaque, calculus and stain and sub-gingival deposits
nsure that local plaque retentive factors which may hinder oral hygiene efforts, such as overhanging restorations, are corrected
Where the gingival enlargement hinders adequate oral hygiene or interferes with the normal function of the oral cavity, consider referring to a consultant in paediatric dentistry, consultant in restorative dentistry or specialist periodontist.

65
Q

what is unexplained gingival enlargement

A

inflammation and bleeding can be a sign of undiagnosed leukemia in children and adults
In cases where the gingivitis or gingival enlargement does not respond to treatment as expected or the extent of the condition is inconsistent with the level of oral hygiene observed, consider urgent referral to a physician

66
Q

what are the key recommendations of treatment of periodontal conditions

A

• Ensure the patient is able to perform optimal plaque removal.
• Remove supra-gingival plaque, calculus and stain and correct
any local plaque retentive factors. Carry out root surface instrumentation at sites ≥4 mm probing depth where sub-gingival deposits are present or which bleed on probing.
• Do not use antimicrobial medication to treat chronic periodontitis.

67
Q

where does non-surgical periodontal therapy begin

A

it begins by motivating and instructing the patient in adequate self care, followed by re-evaluation of his/her level of oral hygiene.

68
Q

what does non surgical instrumentation do

A

disrupt the plaque biofilm and remove calculus to give a clean, smooth tooth/root surface can then be completed both supra- and sub-gingivally

69
Q

What is the key to success in the treatment of periodontal conditions

A

Key to the success of non-surgical periodontal therapy is regular re-enforcement of oral hygiene advice, regular, effective removal of the plaque biofilm38-41 and, where applicable, smoking cessation advice to bring about a life-long change in patient behaviour.

70
Q

what is the goal of non surgical periodontal treatment

A

to achieve signs of periodontal stability which are easy to sustain

71
Q

what are the optimal outcome of plaque scores

A

below 15%

72
Q

what are the optimal outcome for bleeding

A

below 10%

73
Q

what is the optimal outcome of probing depths

A

less than 4mm

74
Q

What should the dentist do regarding treatment of periodontal conditions

A

explain to the patient the potential benefits of successful treatment
explain to the patient their role in improving periodontal health
use the TIPPS strategy
remove supra gingival plaque, calculus and stain
carry out RSI at sites of >4mm probing depth where sub gingival deposits are present or which bleeding on probing. local anaesthetsia may be required for this. only instrument sites of <4mm probing depths where sub-gingival deposits are detected
advise the patient that they may experience some discomfort and sensitivity following treatment and to expect some gingival recession as a result of healing
carry out a full PDE

75
Q

what is the cleaning of subgignival root surface called

A

the cleaning of sub-gingival root surface is termed root surface instrumentation (RSI). It can equally be called root surface debridement (RSD)

76
Q

what does the technique of RSI aim to do

A

This technique aims to mechanically remove microbial plaque and calculus without any intentional removal of the root surface. However, it is accepted that since root surface instrumentation is conducted blind, some removal of the root surface cementum may inadvertently occur.

77
Q

how can RSI be done

A

using hand instruments or powered scalers (sonic or ultrasonic)

78
Q

how is successful utilization of instruments done

A

Successful utilization of these instruments requires a thorough understanding of root anatomy and knowledge of which instrument works best in a particular area.

79
Q

how should the tips of the sonic and ultra sonic be used

A

use only the sides of the working tip for debridement without applying lateral pressure
use overlapping strokes to instrument all of the affected root surface.

80
Q

how are instruments maintained

A

Overtime the cutting edge of the blade may dull. The hand instruments require meticulous maintenance to ensure that they remain fit for purpose.

81
Q

how long should treatment be

A

The time taken to instrument each tooth will depend on the level of deposits, the tooth type, the depth of the pocket, whether there is furcation involvement, the presence of challenging anatomy and the location in the mouth. It can take several minutes of instrumentation to effectively debride the root surface adjacent to a deep pocket around a single tooth.

82
Q

why may patients experience pain during RSI

A

due to root surface sensitivity and also because the base of pockets can be inflamed and painful

83
Q

what is not advised regarding appointment planning

A

It is not advised to adopt a process of removing some deposits from all root surfaces at one appointment with the intention to revisit and remove remaining deposits at subsequent appointments.

84
Q

why should you not remove some deposits in one appointment and leave some

A

This is because initial healing, after the gross deposits have been removed can make re-accessing the pocket more difficult and partial removal of deposits leaves behind rough areas which are ideal for bacterial proliferation. It is advised that the clinician concentrated on as many teeth, sextants or quadrants as can be thoroughly instrumented in the time available.

85
Q

what are examples of local plaque retentive factors

A

mal positioned teeth, overhanging restorations, crown and bridgework, partial dentures and fixed and removable orthodontic appliances

86
Q

what should you do regarding local plaque retentive factors

A

Explain to patients with local factors such as crowded teeth, partial dentures, bridgework and orthodontic appliances, the importance of plaque removal in these areas.
Give instruction on how to clean adequately around fixed restorations and fixed appliances and how to clean removable prostheses.
Ensure that fixed and removable appliances are well-designed and that they are a good fit. Modify overhanging or poorly contoured restorations or replace the restoration.
Consider orthodontic treatment or extraction for mal-positioned teeth.
