Q

How to prepare a CII cavity?

A

Caries accessed through MR, due to loss of contact area, with a matrix band
Avoid damage to adjacent tooth
If using amalgam create undercuts
If using composite rubber dam is essential

Q

How to prepare shallow and deep root caries?

A

Shallow: - recontoured and Fl applied, if they’re cleansable then restoration may not be necessary
Deep:
- remove caries and restore with GIC or composite

Q

How to prepare a patient for a rubber dam?

A

General outline to patient
Teeth cleaned and contacts checked with floss
Rough contacts smoothed
If occlusal restoration work planed, occlusion should be marked prior
Lips lubricated
LA given for clamp

Q

How many holes to punch for a posterior tooth?

A

Tooth needed for restoration as well as one further distal tooth

24
Q

How to apply the rubber dam clamp?

A

Clamp bow towards distal aspect
Apply from lingual to buccal
Ensure 4 point contact

25
How to prepare the enamel of a cavity?
Gain visual access of the carious lesion Remove demineralised, weakened carious enamel Create a peripheral enamel margin to be able to form a seal High speed
26
How to correct enamel margins?
Unsupported enamel is weak and prone to fracture Thin section of material is weak and prone to fracture Bevel to increase surface area for bonding (not amalgam)
27
How to correctly remove dentine from a cavity?
Lateral extent from the EDJ periphery to the caries overlying the pulp Slow speed Circular brush-strokes
28
What is the definition of a line angle?
Where 2 surfaces meet
29
What is the definition of the cavosurface angle?
Where the cavity wall meets tooth surface (between 90-110)
30
What is the cavo-surface angle for amalgam and composite?
Amalgam: - 90 Composite: - >90, with bevel
31
What is the definition of a point angle?
Where 3 or more surfaces meet
32
What is the purpose of rounded angles?
Reduces stress in restored unit | Reduces loss of tooth tissue
33
What occlusal anatomy should you try and preserve?
Oblique ridge in max molars | Marginal ridge in anterior/premolar teeth
34
Explain the clinical protocol for a fissure sealant?
``` Isolate - rubber dam Clean tooth Etch for 20-30s Wash for 10-20s and then dry for same amount of time Apply FS Apply light for 20-30s Check sealant for seal and retention ```
35
Explain the clinical protocol for a PRR?
``` Etched for 20s Washed for 10s Primer for 10s Gently air dry to leave fine layer Apply 2-3 coats of adhesive Gently air dry and light cure for 10s Apply composite to cavity incrementally as required. Shape with burnisher or flat plastic between increments 20-30s light application Apply fissure sealant ```
36
How to recreate a proximal wall for a CII restoration?
Proximal box: - buccolingual extension of 0.2-0.3mm clearance from the adjacent tooth buccally and lingually - gingivally there should be a 0.5 mm from adjacent tooth - axial wall should follow the external tooth contour
37
What is the size of the proximal box?
1.5mm
38
What is the depth of the proximal box?
1.5-2mm
39
Explain the clinical protocol for a CV cavity?
Rubber dam helps to retract gingiva and gives isolation Remove caries Etch, prime and bond Restore with GIC or composite
40
Explain the cavity needs for an amalgam restoration?
``` Depth occlusally at least 2mm Cavity floor flat Walls should be parallel with slight convergence No unsupported enamel margins No sharp angles Undercuts ```
41
Explain the condensation rules of amalgam?
``` Condenser tooth must fit Place amalgam in small increments Condensing for up to 4 mins Overfilled with amalgam Condense with heavy pressure - hear a squeak - promoting adaptation to cavity walls and eliminates voids ```
42
Explain the carving rules of amalgam?
Remove gross excess Use probe to relive a ring around the matrix band and contour the marginal ridge after carving CArver should rest on enamel/cusps adjacent and be parallel to the margin of the prep Do not let tip of carver leave the middle of resto Centre should be smoothed with a burnisher Follow the cusps with tool
43
What to include when reporting on a radiograph?
``` Date taken Type of radiograph Grade Teeth present Caries Restorations Plaque retentive factors Bone level Other ```
44
BPE Code 0?
Pocket <3.5mm | No plaque or calculus/overhangs, no BoP (black band entirely visible)
45
BPE Code 1?
Pocket <3.5mm No plaque or calculus/overhangs BoP (black band entirely visible)
46
BPE Code 2?
Pocket <3.5mm Supra or subgingival plaque/calculus/overhangs (black band entirely visible)
47
BPE Code 3?
Probing depth between 3.5-5.5mm | Black band partially visible, indicating a pocket 4-5mm
48
BPE Code 4?
Probing depth >5.5mm | Black band disappear, indicating a pocket of 6mm or more
49
BPE Code *
Furcation involvement
50
Treatment for BPE Code 0?
None
51
Treatment for BPE Code 1?
OHI
52
Treatment for BPE Code 2?
OHI | Removal of plaque retentive factors, including all supra and subgingival calculus
53
Treatment for BPE Code 3?
OHI Removal of plaque retentive factors, including all supra and subgingival calculus 6 point pocket chart recording pockets over 4mm (in that sextant) Possible root surface debridement
54
Treatment for BPE Code 4?
OHI RSD 6 point pocket chart in all sextants Assess for more complex treatment (UNC15)
55
What to include for a periodontal assessment?
``` Type Distribution Stage Grade Status Risk factors ```
