1
Q

How can periodontal diseases and conditions be classified in the 2017 classification system?

A

Periodontal health, Gingival disease and conditions
Periodontitis
Other conditions affecting the periodontium

2
Q

Name the 4 periodontal structures

8
Q

How does the body ensure an intact epithelial barrier is maintained?

A

Shedding of epithelial cells - replaced by new cells. Junctional epithelium has a very high turnover rate
Outflow of GCF
Antimicrobial effects of antibodies

9
Q

Signs of periodontal disease?

Plaque around gingival margin

Q

Define dental plaque biofilm

A

Collection of microorganisms, held together within a matrix structure, on a surface or interface

13
Q

What are early dental plaque biofilm colonisers?

A

Streptococcus

14
Q

What are the later colonisers of plaque biofilm?

A

Rod shaped (G +ve) e.g. actinomyces

15
Q

What is the ecological plaque hypothesis?

A

Non specific pathogenic species of bacteria cause disease due to a shift in bacteria population and biofilm balance

16
Q

How is gingivitis diagnosed?

A

Clinical appearance
BOP
Plaque indices

17
Q

How is initial examination of the gingiva carried out?

A

BPE - a screening tool

18
Q

BPE score 0

A

Pockets <3.5mm
No calculus/overhangs
No BOP

19
Q

BPE score 1

A

Pockets <3.5mm
No calculus/overhang
BOP

20
Q

BPE score 2

A

Pockets <3.5mm

Supra or sub gingival calculus/overhangs

21
Q

BPE score 3

A

Pockets 3.5-5.5mm

22
Q

BPE score 4

A

Pockets >5.5mm

23
Q

Patient has code 0/1/2 and <10% BOP. What is the diagnosis?

A

Clinical gingival health

24
Q

Patient has code 0/1/2 and 10-30% BOP. What is the diagnosis?

A

Localised gingivitis

25
Q

Patient has code 0/1/2 and more than 30% BOP. What is the diagnosis?

A

Generalised gingivitis

26
Q

What are false pockets?

A

Present when junctional epithelium is still at CEJ but the sulcus is deepened to more than 3mm due to changes in gingival swelling

27
Q

Diagnosis of gingivitis

A

No pocket depths >3mm - BPE code 0/1/2
BOP - amount dictates severity of disease
Redness, swelling, heat
NO bone destruction or breakdown of PDL

28
Q

Consequence of necrotising gingivitis?

A

Sloughing of gingival margin, ulceration, painful

29
Q

Aetiology of necrotising gingivitis?

A
Poor OH
immunocompromised
Poor diet and general health
Smokers
Stress
30
Q

List 8 local contributing factors of gingivitis

A
Dental plaque
Supra/subgingival calculus
Suboptimal restoration margins
Tooth anatomical factors
Malocclusion/crowding
Fixed/removable prosthodontics/ortho
Incompetent lips/lack of seal
oral dryness (mouth breathers, xerostomia)
31
Q

List 8 systemic factors that can contribute to gingival disease?

A
Puberty
Pregnancy
Menstrual cycle
Diabetes
Blood dyscrasia (leukaemia)
Medications - amlodipine
malnutrition (Vit C deficiency)
Smoking - vasoconstriction
32
Q

Why might smokers not notice signs of gingival disease as soon as non-smokers?

A

Causes vasoconstriction so stops bleeding.

Non-smokers will notice more bleeding sooner

33
Q

How is plaque-induced gingivitis managed?

A

OHI
Biofilm destruction - scale, toothbrushing
Removal of retentive features

34
Q

Describe how pregnancy-associated gingivitis occurs?

A

Increased hormone levels increasing vascular permeability into gingival tissues

35
Q

How should pregnant patients be managed?

A

OHI
Recall - every 3 months
identify stage of pregnancy - should get better in 3rd trimester
