Periodontal instrumentation Flashcards
Periodontal hand instruments? Types and use?
Sickle scaler - supragingival
Curettes - subgingival
Scaling - Definition?
Instrumentation to remove deposits from the surface of a tooth apical to the gingival margin accumulated in periodontal pockets or the surface coronal to the gingival margin
Root surface debridement (RSD) - Definition?
Instrumentation of the diseased root surface without deliberate removal of the cementum.
The goal is to conserve cementum and help maintain or re-establish a health periodontal environment
Sickle scaler? Type? Purpose? Parts? Technique of use?
Universal sickle S204 (adapted to every tooth)
Remove medium and large sized deposits from the supra and sub marginal area of the tooth
Working tip projecting from the shank at roughly a right angle and having a sharp pointed end (2 cutting edges) (triangular)
Keep working shank parallel to the long axis of the tooth, to create the correct angulation:
- tilt towards tooth
- tip third to tooth surface
- explore over the surface and over deposits
Periodontal examination? The 3 main parts?
General description of the periodontal condition
Periodontal screening using the BPE
Detailed exam of the periodontal tissues and recording of the periodontal indices
General description of the periodontal condition? Presence of?
- gingival inflammation
- swelling
- loss of contour
- gingival recession
- suppuration
- supra and subgingival plaque
- calculus deposits
- occlusal problems (drifting)
- local periodontal risk factors
The BPE probe - Use? Parts? Pressure? Sextants?
The WHO BPE:
- 0.5mm spherical ball tip to aid detection of subgingival calculus deposits and limit penetration at the base of the pocket
- black band 3.5-5.5mm to delineate normal sulci and periodontal pockets
- recommended probing force of 20-25g
Use: sextants;
- sextants are 7-4, 3-3 and 4-7
- must contain at least 2 teeth
- if only 1 tooth is present add it to the adjoining sextant
- probe is ‘walked around’ and the highest score recorded
BPE scoring codes? 0-4*?
0: Pocket <3.5mm
- no calculus/overhand, no BOP (black band visible)
1: Pocket <3.5mm
- no calculus/overhand, BOP (black band visible)
2: Pocket <3.5mm
- supra or subgingival calculus/overhand, BOP (black band visible)
3: Probing depth 3.5-5.5mm
- black band partially visible, indicating pocket of 4-5mm
4: Probing depth >5.5mm
- black band disappears, indicating pocket of >6mm or more
* : furcation involvement
Code 3: initial therapy including self-care advice then, post-initial therapy, record a 6-point pocket chart in sextant only
Code 4: record a 6-point pocket chart throughout the entire dentition
Code 0 - Clinical signs? Management?
All black band visible
No bleeding on probing
No management needed
Code 1 - Clinical signs? Management?
All black band visible
No calculus or defective margins
Bleeding on probing
Management:
- chart gingival bleeding, disclose and chart plaque
- individualised OHI and prophylaxis
Code 2 - Clinical signs? Management?
All black band visible
Supra or subgingival calculus detect or defective margins of crown/restoration
Management:
- chart gingival bleeding, disclose and chart plaque giving OHI
- remove defective margins, plaque retentive factors, including supra and subgingival calculus
Code 3 - Clinical signs? Management?
The black band is partially visible
Management:
- initial therapy including self care, OHI and risk factor control, then post initial therapy by recording a 6 point pocket chart in that sextant only (recording depths above 4mm
- RSD if required
Code 4 - Clinical signs? Management?
The black band disappears
(above 6mm)
Management:
- chart gingival bleeding, disclose and chart plaque giving OHI
- remove defective margins, plaque retentive factors, including supra and subgingival calculus
- full periodontal exam of all teeth (recording pockets 4mm and above)
- once oral hygiene is achieved, RSD where necessary
- review after 8-12 weeks
- assess the need for further treatment (supportive periodontal therapy)
When not to use a BPE?
It can’t be used to monitor the response to therapy as it doesn’t give enough detail of individual sites
For patients that have undergone initial therapy for periodontitis and who have gone on to the maintenance phase
BPE overview?
- If BPE = 0, screen again at routine recall visit or within 1 year, whichever the sooner
- If BPE = 1 or 2, treat and screen again at routine recall or after 6 months, whichever the sooner
- If BPE = 3, record full probing depths (6 sites per tooth) on the index tooth and check other teeth in the sextant, treat (OHI and root surface debridement (RSD) and review after 3 months
- If BPE = 4 or *, undertake full periodontal assessment and consider referral
