Perio Flashcards
What is the sequence of carrying out a 6PPC?
Buccal Q1 Buccal Q2 Palatal Q2 Palatal Q1 Buccal Q4 Buccal Q3 Lingual Q3 Lingual Q4 Record gingival margin, pocket depth, BoP, furcation and any mobility
What information is recorded on a review pocket chart?
Pocket equal to or greater than 4mm (whole mouth is probed)
Plaque, calculus and BoP
What are the advantages and disadvantages of a 6PPC?
Advantages - gives a full picture of periodontal attachment loss
Disadvantage - Is more time consuming
What are the advantages and disadvantages of an abbreviated/review pocket chart?
Advantages - Quicker to complete than 6 PPC. Can efficiently highlight areas requiring further treatment.
Disadvantages - Does not record periodontal attachment loss, which could therefore progress unrecorded
In ultrasonic debridement, what factors lead to root surface loss and ledges?
- Excessive lateral force
- Incorrect angulation/adaptation
- Incorrect insert width
- Excessive power
Describe the mini sickle (Red)
- Red
- Double ended point scaler
- Two cutting edges on each blade
- Used on buccal and lingual embrasure surfaces supragingivally
- Limited in subgingival use
Describe the hoe scaler 134-135 (yellow)
-Double ended instrument for gross supra and subgingival scaling mainly on buccal and lingual surfaces
Describe the hoe scaler 156-157 (red)
-A double ended instrument for gross supra and subgingival scaling mainly on mesial and distal surfaces
Describe the Columbia curette (red)
- Double ended universal curette with two cutting edges on each blade for subgingival scaling anywhere in the mouth but with limited access to deep pockets.
- A curved spoon shaped blade with two cutting edges, which meet to form a rounded toe
What is the application of the Gracey curette 1-2 (Grey)
Subgingival scaling anterior teeth
What is the application of the Gracey curette 7-8 (Green)
Subgingival scaling buccal and lingual surfaces
What is the application of the Gracey curette 11-12 (Orange)
Subgingival scaling mesial surfaces of posterior teeth
What is the application of the Gracey curette 13-14 (Blue)
Subgingival scaling distal surfaces of posterior teeth
What are Ramfjords teeth and what are they used for?
16, 21, 24, 36, 41, 44
These six teeth are used to record plaque and bleeding index
What surfaces of Ramfjords teeth are used in a modified plaque score?
- Interproximal
- Buccal
- Palatal/lingual
What are the three possible scores in a modified plaque score?
2 = visible plaque without use of a probe 1 = no visible plaque but a probe skimmed over tooth surface reveals plaque 0 = no plaque
All scores are added together to give a total, which is then divided by the maximum plaque score possible (36)
What is the purpose of staging periodontal disease and what are the four stages?
Staging is based on severity.
Stage 1 - Early/mild. Interproximal bone loss less than 15% or 2mm
Stage 2 - Moderate. Coronal third of root involved.
Stage 3 - Severe (potential for additional tooth loss), mid third of root involved.
Stage 4 - very severe (posential for loss of dentition) Apical third of root involved
What is the purpose of grading periodontal disease and what are the three grades?
Grading indicates the progression of bone loss.
Grade A - slow - less than half patients age
Grade B - moderate half to equal to patients age
Grade C - rapid - greater than patients age
How is the extent of periodontal disease recorded?
- Localised - less than 30% of teeth
- Generalised - greater than 30% of teeth
- Molar incisor pattern
Describe type 1 recession
Gingival recession with no loss of interproximal attachment. Interproximal CEJ is clinically not detectable at both mesial and distal aspects of the tooth
Describe type 2 recession
Gingival recession associated with interproximal LOA. The amount of LOA is less than or equal to the buccal attachment loss.
Describe type 3 recession
Gingival recession associated with loss of interproximal attachment. The amount of interproximal attachment loss is greater than the buccal attachment loss.
