Periodontal Examination Flashcards
(32 cards)
Clinical features of periodontitis
Pocket formation Loss of attachment Swelling Erythema BOP Alveolar bone resorption Tooth mobility Recession Halitosis
True vs false pocketing
True pockets - result from apical migration of junctional epithelium following loss of connective tissue attachment
False - result from gingival enlargement with no alteration in position of junctional epithelium
Horizontal vs vertical bone loss
Horizontal - entire width of interdental bone resorbed
Vertical - interdental bone adjacent to root surface more rapidly resorbed
Why does pathological mobility occur?
Loss of connective tissue attachment
Depends on level of bone loss, degree of inflammation and magnitude of occlusal forces
What can occur as a result of tooth mobility?
Migration of teeth
Why does halitosis occur in periodontitis?
G-ve, anaerobic bacteria produce production of volatile sulphur compounds
What are 2 common intra-oral sources of halitosis?
Periodontal pockets and crypts on tongue - large anaerobic areas
List 3 medical history points that can cause periodontal disease
Medications e.g. calcium channel blockers - gingival overgrowth
Diabetes - if glucose not controlled = risk of PD
Rheumatoid arthritis - struggle with brushing
Hormone changes - pregnancy, puberty
What factors in social history can effect periodontal disease?
Smoking
Occupation (shifts - tired = less brushing)
Stress - hormones
Family history
Is BPE a screening or diagnostic tool?
Screening
What BPE score will require further investigation?
Codes 3 or 4
Describe BPE probe?

Black band 3.5-5.5mm
BPE score 0
No pockets <3.5mm
No calculus/overhangs
No BOP
BPE score 1
No pockets <3.5mm
No calculus/overhangs
BOP
BPE score 2
No pockets <3.5mm
Supra/sub-gingival calculus/overhangs
BPE score 3
Probing depth 3.5-5.5mm
BPE score 4
Probing depth >5.5mm
You complete a BPE on a patient have they have 1 score of 4. What do you do?
Full mouth periodontal assessment
You complete a BPE on a patient and they require 1 BPE score of 3. What do you do?
Initial therapy - OHI, risk control, RSI, review
Post-initial therapy - review, localised periodontal charting in affected area
What are the 7 components of a full periodontal assessment?
Radiographs Six point pocket chart (PPD) Six point bleeding on probing assessment Assessment of recession Assessment of mobility Furcation involvement Plaque score
If you are going to treat a patient for periodontal disease. What is a good way to measure progress?
Plaque score before treatment and review
Describe how you would measure PPD
Probe parallel to tooth, record 6 sites per tooth
When is furcation involvement recorded in a full periodontal examination?
During PPD
What probes can be used for full periodontal examination?
UNC probe or Williams probe
Each have bands to show mm
