A

Periodontitis is considered localised if there is <30% teeth affected or generalised if >30% teeth affected

65
Q

Apart from localised or generalised periodontitis, howe else can it be classified?

A

After a 6PPC
Can be classified as “Periodontitis molar-incisor pattern” if a molar incisor pattern is identified
Staging, grading, current disease status and risk factor assessment must then be conducted to produce a diagnosis statement

66
Q

How do you compose a periodontal diagnostic statement?

A

Diagnostic statement: Extent - Periodontitis - Stage - Grade - Stability - Risk factors

67
Q

What is “Staging” in relation to a periodontitis diagnosis?

A

Stage is the severity of interproximal bone loss
You use your radiographic assessment (periapicals or OPG) and choose the worst site
Stage I - <15% (or >2mm AL from CEJ) - Mild/early
Stage II - Coronal third of root - Moderate
Stage III - Mid third of root - Severe
Stage IV - Apical third of root - V Severe

68
Q

What should you do to determine the stage of periodontitis if there are no periapical or OPG radiographs?

A

Use CAL or bone loss from CEJ

69
Q

What is “Grading” in relation to a periodontitis diagnosis?

A

Grade is the susceptibility to bone loss, using periapicals or OPG choose the worst site to determine slow/moderate/rapid rate of progression
This is worked out as (% bone loss)/(patient age)
Grade A - <0.5 - Slow
Grade B - 0.5-1 - Moderate
Grade C - >1 - Rapid

70
Q

How do you determine current disease status in relation to periodontitis?

What are the different statuses?

A

You look at

  • % of BoP
  • Probing pocket depth
  • BoP at 4mm sites

Stable - BoP <10%, PPD <4mm, No BoP sites of 4mm
Remission - BoP >10%, PPD <4mm, No BoP sites of 4mm
Unstable - PPD >5mm OR PPD >4mm & BoP

71
Q

In the 2017 Classification of Periodontal Diseases how do you use a BPE assessment Code 0/1/2 to form a diagnosis?

A

<10% BoP - Clinical gingival health
10-30% - Localised gingivitis
>30% - Generalised gingivitis

Diagnosis should also include a comment on plaque retentive features where a BPE code 2 is present

72
Q

In the 2017 Classification of Periodontal diseases how do you use a BPE assessment Code 3 to form a diagnosis?

A

Use appropriate radiographic assessment to aid diagnosis (periapicals or OPG)
Conduct initial periodontal therapy and review in 3 months with localised 6PPC in involved sextants

  • If no pockets >4mm and no bone loss due to periodontitis evident on radiograph then use code 0/1/2 pathway
  • If pockets >4mm remain and/or radiographic evidence of bone loss due to periodontitis then use code 4 pathway
73
Q

In the 2017 Classification of Periodontal diseases how do you use a BPE assessment Code 4 to form a diagnosis?

A

Use appropriate radiographic assessment (periapicals or OPG)
Full periodontal assessment

If <30% teeth affected - Localised periodontitis
>30% - Generalised periodontitis

Also look for molar incisor pattern

To form a diagnostic statement - staging, grading, current disease status and risk factor assessment need to be conducted

74
Q

If a 0 is scored in the BPE, what is the appropriate treatment according to the guidelines?

A

No need for periodontal treatment

75
Q

If a 1 is scored in the BPE, what is the appropriate treatment according to the guidelines?

A

OHI

76
Q

If a 2 is scored in the BPE, what is the appropriate treatment according to the guidelines?

A

OHI and removal of all plaque retentive factors which may involve supra and sub gingival scaling to remove calculus

77
Q

If a 3 is scored in the BPE, what is the appropriate treatment according to the guidelines?

A

OHI and Root Surface Debridement

As a general rule, radiographs to assess alveolar bone levels should be obtained for teeth or sextants
where BPE codes 3 or 4 are found.

78
Q

What is Root Surface Debridement?

A

Scaling is when your dentist removes all the plaque and tartar (hardened plaque) above and below the gumline, making sure to clean all the way down to the bottom of the pocket. Your dentist will then begin root planing, smoothing out your teeth roots to help your gums reattach to your teeth.

79
Q

If a 4 is scored in the BPE, what is the appropriate treatment according to the guidelines?

A

OHI, RSD. Assess the need for more complex treatment; referral to a specialist may be indicated

As a general rule, radiographs to assess alveolar bone levels should be obtained for teeth or sextants
where BPE codes 3 or 4 are found.

80
Q

What is the treatment for gingivitis or gingival enlargement?

A
  • Explain to the patient that untreated gingivitis is a risk factor for periodontitis, which can lead to tooth loss, but he/she can reduce this risk with OH
  • Use TIPPS method to highlight how importance of effective plaque removal and show pt how they can achieve this
  • Remove supra-gingival calculus/plaque/stain and sub-gingival deposits using appropriate method. Highlight to the patient areas where supra-gingival deposits are detected
  • Ensure local plaque retentive factors are corrected, e.g. remove overhanging restorations or alter denture design
  • Re-assess at a future visit to determine whether the gingivitis has resolved
81
Q

What is TIPPS and how does it relate to the patients OH?

A

TALK - About causes of periodontal disease/any barriers for effective plaque removal
INSTRUCT - pt on best ways for plaque removal
PRACTICE - Ask pt to practice cleaning method and interdental cleaning whilst in dental setting, correct pts technique if necessary
PLAN - Make plan how pt will incorporate OH into daily routine
SUPPORT - Follow up at next visits

82
Q

What commonly prescribed drugs for hypertension, epilepsy and autoimmune disorders can cause gingival enlargement?

A

Calcium channel blockers - Hypertension
Phenytoin - Epilepsy
Ciclosporin - Anti-rejection drug used for Autoimmune disorders

83
Q

What is the treatment for drug-induced gingivitis?

A
  • Ensure you have an up-to-date medical history
  • Use TIPPS method to highlight how importance of effective plaque removal and show pt how they can achieve this, smoking cessation where needed
  • Remove supra-gingival calculus/plaque/stain and sub-gingival deposits using appropriate method. Highlight to the patient areas where supra-gingival deposits are detected
  • Ensure local plaque retentive factors are corrected, e.g. remove overhanging restorations or alter denture design
  • 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.
  • Re-assess at further visit to determine whether the gingival enlargement has been resolved
84
Q

Briefly how does pregnancy associated gingivitis occur?

A

Due to the change in hormone levels and due to the immune response associated with pregnancy

85
Q

What is the treatment for pregnancy associated gingivitis?

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. Where applicable, give smoking cessation advice
  • Where the condition is severe, 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 supragingival 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.
  • Re-assess at a future visit to determine whether the gingivitis has resolved.
86
Q

Briefly how does puberty associated gingival enlargement occur?

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.

87
Q

What is the treatment for puberty associated gingival enlargement?

A
  • In cases of puberty gingivitis and mild gingival enlargement associated with puberty, 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. Where applicable, give smoking cessation advice.
  • 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.
  • Ensure that local plaque retentive factors which may hinder oral hygiene efforts, such as overhanging restorations, are corrected. Ensure patients are able to clean effectively around fixed orthodontic appliances.
  • 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.
  • Re-assess at a future visit to determine whether the gingivitis or gingival enlargement has resolved.
88
Q

What does unexplained gingivitis/gingival enlargement usually indicate?

A

Unexplained gingival enlargement, inflammation and bleeding can be a sign of undiagnosed leukaemia
in both children and adults.

89
Q

What is the goal of non-surgical periodontal treatment?

A

To achieve signs of periodontal stability.
Optimal outcomes are plaque scores of >15%, Bleeding scores <10%, and probing depths >4mm

Patients with significantly improved oral hygiene,
reduced bleeding on probing and a considerable reduction in probing depths from baseline can be
considered to have responded successfully to treatment and may progress to supportive periodontal
therapy.

90
Q

What is the treatment for periodontitis?

A
  • Remove supra-gingival plaque, calculus and stain. Highlight to the patient areas where supra-gingival deposits are detected. Carry out root surface
    instrumentation (RSI) at sites of ≥4 mm probing depth where sub-gingival deposits are present or which bleed on probing. Local anaesthesia may be required.
  • Advise the patient that he/she may experience some discomfort and sensitivity following treatment and to expect some gingival recession as a result of healing.
    • Proprietary desensitising toothpastes or mouthwashes can be used to treat particular areas of dentine sensitivity following RSI.
  • Carry out a full periodontal examination a minimum of 8 weeks post treatment.
91
Q

How do you treat acute conditions in relation to periodontitis?

A
  • Manage acute conditions using local measures in the first instance.
  • Do not prescribe antibiotics unless there is evidence of spreading infection or systemic involvement.
  • Recommend the use of 0.2% chlorhexidine mouthwash (or 6% hydrogen peroxide for NUG and NUP) until the acute symptoms subside.
  • Recommend optimal analgesia.
  • Following acute management, review within ten days and carry out further supra- and sub-gingival instrumentation as required and arrange an appropriate recall interval.
92
Q

What is the acute management of a perio-endo lesion?

A

Carry out RCT of affected tooth

93
Q

What is the acute management of a periodontal abcess?

A

Carry out careful sub-gingival debridement short of the base of the peridontal pocket, LA may be required.

If pus is present, drain by an incision or through the periodontal pocket.

94
Q

What is the acute management of necrotising ulcerative gingivitis and periodontitis?

A

Use oral hygeine TIPPS to address inadequate plaque removal, smoking cessation if needed.
Remove as much supra-gingival plaque, calculus and stain and sub-gingival deposits as can be tolerated by the patient; local anaesthesia may be required.
If there is evidence of spreading infection or systemic involvement, consider prescribing metronidazole.
If no resolution of signs and symptoms occurs, review the patient’s general health and consider referral.

95
Q

What is the supportive periodontal therapy for patients with a history of periodontitis?

A
  • Ensure that full mouth periodontal charting is performed annually in patients who scored BPE 4 in any sextant at baseline and in patients who scored 3 in more than one sextant at baseline.
    • Where the patient scored BPE 3 in only one sextant, carry out full periodontal charting of that sextant.
  • Remove supra-gingival plaque, calculus and stain using an appropriate method. Carry out RSD at sites of ≥4 mm probing depth where sub-gingival deposits are present or which bleed on probing. Local anaesthesia may be
    required.
96
Q

How do you manage patients with dental implants?

A
  • Ensure that a baseline periapical radiograph of the implant is taken one year after superstructure connection to facilitate long term maintenance
  • Assess level of oral hygeine, if necessary utilise TIPPS to encourage adequate plaque removal, smoking cessation if necessary
  • Examine peri-implant tissue for signs of inflammation and bleeding on probing, and/or suppuration (pus discharge). Probe gently around the superstructure to feel for excess cement and sub-mucosal plaque and calculus. Measure probing depths using fixed landmarks. BPE not appropriate for dental implants.
  • Remove supra-mucosal and sub-mucosal plaque and calculus deposits using an appropriate method. Remove sub-mucosal excess residual cement if this is detected. Local anaesthesia may be required.
  • Assign a risk level and schedule recall appointments accordingly.
97
Q

What is peri-implant mucositis and how is it managed?

A

Peri-implant mucositis is an inflammatory lesion of the soft tissues surrounding an endosseous implant in the absence of loss of supporting bone or continuing marginal bone loss.

  • Ensure it is peri-implant mucositis and not peri-implantitis by carrying out a radiographic examination to assess peri-implant bone levels compared with the baseline
  • Remove supra-mucosal and sub-mucosal plaque and calculus deposits using an appropriate method. Remove sub-mucosal excess residual cement if this is detected. Local anaesthesia may be required.
  • Re-assess at a future visit to ensure that the inflammation has settled and a stable situation has been achieved.

Q

What is peri-implantitis and how is it managed?

A

Peri-implantitis is a pathological condition occurring in tissues around dental implants, characterized by inflammation in the peri-implant connective tissue and progressive loss of supporting bone.

  • Carry out a radiographic examination to evaluate peri-implant bone levels compared with the baseline radiograph.
  • If clinically significant progressing crestal bone loss is detected, refer back to the clinician who placed the implant. If this is not possible, treat by removal of supra-mucosal and sub-mucosal plaque and calculus deposits using an appropriate method. Remove sub-mucosal excess residual cement if this is detected. Local anaesthesia may be required. Plus:
  • Arrange a follow-up appointment after 1-2 months to assess the outcome of treatment. Where there is no improvement, seek advice from secondary care.
  • If the inflammation has settled and a stable situation has been achieved, arrange radiographic follow-up in 6-12 months.

Q

What are the pros and cons of using ultrasonic vs hand instruments?

A
  • Ultrasonic tips may allow better access to furcations
  • Powered instrumentations may be faster and less demanding on operator
  • May result in less unwanted tooth tissue removal
  • Powered instruments cause aerosols
  • May leave a rougher surface

Q

How is tooth mobility measured and classified?

A

Move it bucco-lingually, using an index finger on one side of the tooth and an instrument handle on the other. The amplitude of movement of the crown, from its most extreme buccal to its most extreme lingual position is scored as follows:

Grade 1 - <1mm
Grade 2 - 1-2mm
Grade 3 - >2mm or rotation/depression

Grade 3 mobility teeth have poor prognosis.
