|
What angle should the cutting edge of an instrument be?
|
Cutting edge should meet the tooth at an angle less than 90 but greater than 45
|
|
|
The shank of an instrument should be ____ with the long axis of the tooth
|
parallel
|
|
|
An imaginary line that passes through the center of a tooth
|
Long axis
|
|
|
Towards the apex of the tooth
|
apical
|
|
|
towards the crown of a tooth
|
coronal
|
|
|
where 2 tooth surfaces meet
|
line angle
Each tooth has 4 |
|
|
for instrumentation, how is the dentition split up?
|
Into sextants and then further into aspects (facial/lingual)
|
|
|
What are the functions of the probe?
|
Measure sulcus and pocket depth
Measure clinical attachment levels Determine the width of the attached gingiva Assess for the presence of bleeding Measure the size of oral lesions |
|
|
What depth of pocket (in the absence of resession) indicates a healthy gingival sulcus?
|
1-3 mm
|
|
|
What is the proper stroke pressure?
|
10-20 g
|
|
|
What type of probe is used for measureing furcations
|
Nabers probe
|
|
|
What are the classifications of furcations?
|
Class I-slight root indention
Class II-1/2 way through Class III-through and through, covered by gingiva Class IV-through and through exposed |
|
|
Whar are the classes of mobility?
|
N-Normal no movement
Class I-<1mm Class II->1mm Class III->1mm in all directions (depressible) |
|
|
What is femitus? How is it measured? How is it recorded?
|
-Palpable vibrations, excessive contact
Analysis is only done on maxillary teeth -Lightly press finger on cerivcal 1/3 of tooth Have pt lightly tap posterior teeth together |
|
|
How do you record the degree of fremitus?
|
-Record by toothe number
N=Normal +=One degree fremitus, only slight vibration can be felt ++=Two-degree, the tooth is clearly palpable but movement is barely visible +++=three-degree, movement is clearly observed visually |
|
|
What causes a cleft in the gingiva?
|
Aggressive flossing or frenum pulling
|
|
|
In dentrix, how would you chart a PD of over 9?
|
Use the 1_ button. Measurements greater than nine mm appear as > on the data chart
|
|
|
In Dentrix how do you chart if the GM is above the CEJ?
|
Click the + button followed by the appropriate number. Button only works when entering the GM measurement
On the chart the GM appears white in a black square to indicate it's positive |
|
|
How many sites are needed to determine periodontal classification?
Describe how you would determine this classification using the CAL. |
10 sites (round down)
Take the greatest reading found on the facial or lingual of the CENTER calculated CAL. (Proximal sites are taken into consideration radiographically). You should have only one reading per tooth (whichever is a greater CAL on the facial or lingual center measurement) Write this number in the box next to the tooth number on the Perio work sheet. Add up the total number of sites by millimeters (1, 2, 3, 4, 5 mm etc) Must have at least 10 sites in a category to classify as a certain type |
|
|
Periodontal Class
Type I |
No attachment loss (recession) present.
Bleeding may be present (localized or generalized). Mobility may be present. Health-Gingivitis |
|
|
Perio Class
Type II |
Slight Attachment Loss
Attachment loss present (recession). The CAL calculation on the perio chart will have the appropriate # of teeth with 1-2mm charted |
|
|
Perio Class
Type III |
Moderate attachment loss
3-4mm attachment loss |
|
|
Perio Class
Type IV |
Sever/Advanced Attachment Loss
5-6mm |
|
|
What is a pseudopocket?
|
When the gingival margin is above the CEJ
May give a "false" reading in regards to attachment loss Subtract the extra tissue that is above the CEJ |
