Detection Of Morphology And Deposits Flashcards
Methods of deposit detection
Radiographs
Probing
Vision
Tissue changes
Compressed air
Disclosing
Floss
What are the different patterns of calculus formations
Spicules
Ledges
Rings
How is deposit detected on radiographs?
Ledges/blushes on the side of teeth
Mesial and distal
Pros of using radiographs to detect deposits
See subgingivally
Image to show patient
Mobile with patient
Educational tool
Cons of using radiographs as a deposit detection tool
Only 2 dimensional
Radiation
Patient tolerance
Image distortions such as overlaps
What makes good vision
Light
Why do we periodontal probe?
Screening
Baseline information
Detection
Diagnosis
Measuring/monitoring
Evaluating
What are the measurements on a UNC15 probe?
1-15mm
How do you position your probe during periodontal probing?
Probe is angled to keep in contact with tooth surface
What angle is the probe usually inserted at for interproximal probing?
Usually 25-45 degrees
Where is the highest point of disease?
Interproximal
Cons of probing for detection of deposits
Inaccuracies
Time
Patient tolerance
Operator variation
Subjective
Pros of probing for detection of deposits
Immediate
Cheap
Reproducible if same clinician
Level of detail
What is the probing pressure?
25 grams
What could happen if probing pressure exceeds 25 grams?
Cause trauma
Perforate epithelium
Patient will be hesitant in future
What tactile sensations do you feel in normal conditions?
None. The probs moves smoothing from junctional epithelium to gingival margin.
What tactile sensations do you feel with spicules?
Probe transmits gritty sensation to fingers as passes over fine granular deposits.
What tactile sensation do you feel with a ledge of subgingival calculus?
As the probe moves over the tooth surface it moves out and around raised bump and then returns to the tooth surface
Tactile sensation for restoration with overhang margin
Probs path is blocked by overhang and must move away from tooth surface and over restoration
Tactile sensation for restoration with deficient margin
Probs passes over restoration and dips into trace the surface of restorations
Tactile sensation of carious lesions
Probe dips and comes out again as it travel along tooth surface.
Soft lesions it can get stuck or feel sticky.
Cons for lighting as a deposit detection method
Access and skill dependent
Time
Subjective
Poor lighting
Pros for using lighting and a deposit detection method
Immediate
Can show to patient using camera or mirror
Indicator for at home monitoring
Quick
Cost free
Cons for using tissue changes as deposit detection
Poor lighting
Access and skill dependent
Time
Share subjective to each clinician
Knowing what is normal for individual patients
