29
What factors can you visually assess involving periodontal tissue
- Changes in size (recession vs gingival hyplasia) - Colour (pink, red, cyanotic (purple)) - Contour (Pointed = healthy, blunted papilla and bulbous = inflammed) Tone (firm = healthy, spongey and retractable = loss of tissue tone) - Thickness - Consistency - Texture - Position - Location of inflammation
30
How much attached gingiva is required for health?
2mm
31
Amount of keratinised gingiva on thick (flat) phenotype?
Broad Zone
32
Amount of keratinised gingiva on thin (scalloped) phenotype?
Narrow zone
33
Tooth shape of thick phenotype
Square with large contact area and short papilla
34
Tooth shape of thin phenotype
elongated and triangular
35
Does thin phenotype have recession after treatment?
yes - needs to be maintained
36
Does thick phenotype have recession after treatment?
no - resists recession
37
How do we assess plaque and calculus deposits?
Plaque Index - O'leary Index
38
What is Plaque Index - O'leary Index
- Records presence of plaque on individual tooth surfaces (4 per tooth) - Expressed as a whole k=mouth percentage - Can utilise plaque disclosing solution - record presence of plaque at dentogingival level - Can be used as motivating tool
39
What is a frenum
Thin fold of mucosa enclosing muscle fibres which attaches to the lip mucosa, underlying periosteum and bone
40
Where do u see frenae
Maxillary arch - Facial midline stablising lips Mandibular arch - facial midline (stabilising lips), ligual frenum (stabilising tongue)
41
What dental factors are important to identify as they can impact on periodontal health and disease? (12)
Caries fractures Stains Calculus Hypersesitivity Mobility Missing teeth Diastemas Open contacts Crowding/rotation supraeruptions Restorations
42
what are the 7 probe based tests?
Probing Depth Recession Pseudopockets Clinical Attachment loss Bleeding on probing Suppuration on probing Furcation involvement
43
what is the healthy probing depth
1-3mm
44
how is cal calculated
adding recession to proving depth
45
what is suppuration
pus- neutrophil rich exudate seen in poorly controlled diabetics
46
what is a grade 1 furcation
less than 1/3 of the root trunk
47
what is a grade 2 furcation
more than 1/3 of the root trunk but not all the way through
48
what is a grade 3 furcation
through and through
49
what are the 4 common probing errors
- Incorrect angualtion - Probe stopped by restorations - use of probe in different diameters and markings - using high force greater than 25 Ncm
50
what is a furcation
exposed area of where the root divides
51
why does a site bleed on probing
presence of inflammation within a pocket presence of bacteria
52
what does measuring the whole mouth percentage bop indicate?
how much is affected severity
53
what is the main limitation of all periodontal tests including radiographs
only show bone loss that has occured within the buccal and lingual plate
54
what are the 6 advantages of using radiographs
- Relatively non invasive - inexpensive - Quick to produce - provides significant diagnostic -information in one image - can be stored and reassed at anytime - Can estimate disease activity overtime by comparing radiographs
55
what are the 6 disadvantages of radiographs
- exposes patient to xray radiation - insensitive to small changes - retrospective - no current info on disease activity - Cannot detect pocketing - Anatomical structures may overlie lesions in trabecular bone - To detect cancellous bone loss, the cortical bone must be involved
56
Are cone beam CT scans indicated for periodontal diagnosis
no - need a specific reason eg implants
57
horizontal bone loss
flat - easy to debride
58
vertical bone loss
difficult to debride
59
what are the two anatomical features of a tooth that are used for the calculation of radiographic bone loss
root apex CEJ
60
what is the threshold for severe bone loss on an xray
more than 50%
61
what are the 4 special tests in periodontics
pulp testing use a frac finder or tooth sleuth to find cracked cusps Microbiological tests Genetic tests
62
what is frequency of disease: prevelance
Number of disease cases at a given point in time
63
what is frequency of disease: incidence
number of cases appearing over a defined period of time
64
what is senstivity
number of diseased patients who are correctly identified as having disease - that is the diagnostic marker leads to a minimum number of false negative diagnosis
65
What is specificity
the number of healthy persons who are correctly determined to not have the disease - that is the diagnostic marker leads to a minimum number of false positive diagnosis
66
who does periodontitis risk increase in
Males smokers increases with age
67
how is plaque index measured
assesses the presence or absense of plaque deposits at gingival margin as y/n
68
how is gingival index measured
scores severity of gingival inflammation 1-4 average core/tooth = GI tooth Average score/dentition = GI Dentition
69
how is BOP measured
assessed by absence or presence y/n expressed as a whole mouth percentage
70
what are indicies
numerical expressions representing a defined set of disease criterea - summarise and characterise the disease state of a patient
71
what are the four limitations of periodontal indicies
no assessment of past periodontal disease no record of alveolar bone loss or recession record of calculus assumes bop has occured even if it hasnt (overestimates bop) presence of deeper pockets persisting after treatment assumes presence of calculus and bop as they are in the same code
72
what does BPE stand for
basic periodontal examination
73
what does PSR stand for
periodontal screening and recording
74
what does CPITN stand for
community index of periodontal treatment needs
75
what does code 0 indicate for periodontal indices
nothing - preventative care
76
what does code 1 indicate for periodontal indices
BOP for BPE, PSR and CPITN
77
what are the treatment recommendations for code 1
oral hygiene instructions and plaque and stain removal
78
what does code 2 indicate for periodontal indices
BOP, calculus, overhangs/defective resto margins for BPE, PSR and CPITN
79
what are the treatment recommendations for code 2
OHI plaque and calculus and stain removal remove overhangs
80
what does code 3 indicate for periodontal indices
3.5-5.5mm pockets for BPE, PSR and CPITN
81
what are the treatment recommendations for code 3
radiographs, subgingival debridement OHI possible referal
82
what does code 4 indicate for periodontal indices
greater than 5.5mm pockets for BPE, PSR and CPITN
83
what are the treatment recommendations for code 4
full perio chart complex treatment including surgery referal to specialist
84
what does code * indicate for periodontal indices in BPE
furcation involvement of CAL greater or equal to 7mm
85
what does code * indicate for periodontal indices in PSR
furcation involvement, abnormal tooth mobility, mucogingival problems or significant gingival recession
86
what does code * indicate for periodontal indices in CPITN
furcation involvement
87
