Periodontal Disease Flashcards
What is the epidemiology of periodontitis?
Effects 37% of uk population moderately (pocketing 4-5mm)
Effects 8% ok uk population severely (pocketing >6)
Effects 11% of worlds population
What is periodontitis?
An inflammatory process that affects the periodontal supporting structures ( gingiva, periodontal ligament, cementum and alveolar bone)
Causes by host/ parasite interactions leads to loss of connective tissue (PDL) and can also be resorption of alveolar bone
Forms pockets and teeth can become mobile
What are clinical features of periodontitis?
- colour change and inflammation at gingival margins
- bleeding on probing
- recession of gingival margin
- loss of alveolar bone
- root Furcation
- mobility of teeth
What is a basic periodontal exam (PBE)
A screening tool used to indicate the level of further examination needed and treatment guidance, it is not a diagnostic tool
What is looked out for in a BPE?
Screening involves assessing bleeding, presence of plaque or calculus and the depth of periodontal pockets which may be present
How are BEP scores recorded for adults?
- Only done for anterior 3 and posterior 4-7 (8 are never included due to not always being present)
- Split the mouth into sextants (6ths and must have at least 2 teeth) and all teeth are examined
- Probe is gently walked around gingival sulcus/pocket (20-25g of pressure)
- Highest score is taken at each sextant
How instrument is used for a BPE screening? And what makes it special?
WHO probe
- has a rounded ball end with a 0.5 diameter
- a black band which around 3.5-5.5mm and one at 8.5-11.5mm to measure pockets
Use around 20-25g of pressure when probing
What is a BPE code 0?
- No calculus or plaque
- No bleeding
- black band entirely visible
Pocket <3.5mm
What is a BPE code 1?
- No calculus or plaque
- Bleeding on probing
- Black band visible
Pocket <3.5mm
What is a BPE code 2?
- Has calculus or overhangs (supra or sublingual)
- Bleeding on probing
- black band still visible
Pocket <3.5mm
What is a BPE code 3?
- Has calculus/ overhangs
- Bleeding on probing
- Black band partially visible
Pocket depth 4mm-5.5mm
What is a BPE code 4?
- Calculus/ overhangs
- Bleeding on probing
- Black band no longer visible
Pocket depth >5.5mm
What does a * BPE code mean?
This mean there is Furcation involvement
- between 2 roots effects 4,6,7,8 (multi roots )
How to code a Furcation
Must always be another number alongside Furcation e.g. 0* or 3*
What are the uses of a BPE check?
- Allows for quick assessment of periodontal disease
- Allows clinician to differentiate simple and complex cases
On at risk patient should be done once a year
