PAR SCORE Flashcards
What does PAR stand for?
Peer Assessment Rating
What is PAR?
• Indicie
• Cumulative Score
• Measures the success of trt
• Components x weighed factor
Why is PAR needed?
• Checks clinical standards
• NHS requirement - KPI
•10 % of the contract
• practices asked twice a year
• > 30 case a year
Disadvantages:
• OJ - heigh weighing factor
• OB - low weighing factor - traumatic OB - doesn’t represent functionality and appearance
• Microdontia and Hypodontia penalised
• Impacted teeth disregarded
• Pre Par scores < 22 can not be greatly improved due to reduction of 30% which is > 22
What are the 5 components of PAR?
- U+L Anterior Segments
- Right and Left Buccal Segments
- OJ and Reverse OJ
- OB and Openbites
- Centrelines
What is recorded in the component:
1. U + L Anterior Segments
• contact displacements
• 3-3
What is the weighing factor for U+ L Anterior Segments?
x 1
What three things are recorded in the R + L Buccal Segments?
- AP - Molar relationship 7-3
- Vertical - Open bites 7-3
- Transverse - Crossbites 7-4
What is the R + L Buccal Segments weighing Factor?
x 1
What is the weighing factor for OJ?
x 6
What area is covered for the OJ?
2-2
What area is covered for a reverse OJ?
3-3
What is area is recorded for the OB?
2-2
What is the OB measured in?
1/3
What is the OB weighing factor?
X2
What is measured for the centerlines?
The upper in relation to the lower in 1/4
What is the weighing factor for centerlines?
X 4
What is the formula for PAR?
(Pre par - post par) x 100
What are the 3 categories for the results of PAR?
• worse/ no different
• Improved
• Greatly Improved > 40 %
For a Post Par score to be excellent what does it need to be?
<5
For a PAR score to be unacceptable, what does the PAR need to be?
> 10
What does the Reduction and Pre par score need to be for greatly improved?
30%
> 22
What must a practice have a score of?
70% good
And no more than 10% of > 10 post par
What would be an example of > 10 post par
