Notes from the QUIZ!
Sinuses= start @ PM
Zygomatic process= by molars (MB of 7) + thicker
Remembering L vs. R for x-ray
Looking @ Pt straight on
When exposing max PA, sensor needs to be placed further away from teeth to achieve paralleling technique **Sensor to tooth= parallel
Bfr exposing image, it is required to…
Clinical exam, dental exam, med history!!!!
Anterior PA= vertical
Posterior PA= horizontal
Session #9 Learning outcomes
ID sequence of interpretation
Discuss evaluation vs. interpretation of radiographic images
ID need for QA (Quality Assurance Program)
Explain comprehensive QA + Implementation in priv practice to meet regulatory requirements
Evaluation vs. Interpretation
Evaluation: (EXPECTATION FOR Y2)
Orient img
ID teeth present
Mount (anatomic order)
Artifacts (scratches, fraying on edges, metal objects)
Technique errors
Interpretation: (EXPECTATION FOR Y3 + look from L—>R)
Normal anatomy (even more than Y2)
Pattern of trabeculation
Root morphology
Does root look like what it is suppose to look like, sometimes body may resorb root
Periodontal assessment
Lamina dura, crestal bone, PDL, consistency, intact
Restorations & caries
Understand what composite filling or crowns look like
Alberta—> DH can diagnose caries
In BC —> “I suspect there is a caries here”
**Looking L —> R to compare against adjacent exposures
Systematic Review
Introduction to PA’S
Just some images + technique errors
Quality Assurance
QA= mandated under Safety Code 30
Formatted + monitored by BCDA
Inspections every 3 yrs
Ultimate responsibility of owner (DHP or DMD)
Often administered by dental team
Practice standard #9-CDHBC
What is the purpose of stepwedge
Little step block that is used to ensure output of radiation
Exposed 1x a week
Achieved for comparison
At UBC done by CDAs
What are retake logs
Retakes need to be considered carefully bcs inc dose to client
Log to track common errors
Consider continuing education to address gap in knowledge
