|
curved probe is used for what?
example? |
nabers probe
furcation detection only |
|
act of walking tip of probe along base of sulcus or pocket for purpose of assessing the health status of periodontal tissues
|
probing
|
|
what forms the base of a sulcus pocket, feels soft and flexible when touched?
|
the junctional epithelium
|
|
stroke pressure for probe?
|
10 - 20 grams
|
|
where si the probe tip located?
|
1-2 mm of side of probe and is kept in contact with tooth throughout walking stroke
|
|
probe should always be what to the long axis of tooth?
|
PARALLEL
|
|
bleeding is a sign of what? and caused by what?
|
inflammation caused by bacterial plaque ulcerating the sulcular epithelium
|
|
refers to estimated position of the structures that support the tooth as measured with a probe, provides estimate of tooth's stability and loss of bone support
|
CAL
|
|
why arent probing depths reliable indicators of extent of bone support ?
|
they are made from gingival margin which change due to tissue swelling, overgrowth, and recession
|
|
where is the CAL calculated from
|
Cemento enamel junction
CEJ |
|
Why is CAL measured @ CEJ
|
becasue the bone level in health is about 1-2 mm from the CEJ, it represents a reliable indication of the extent of bone support of tooth
|
|
when recession is present how is the CAL calculated?
|
ADDING the probing depth to the gingival margin level
|
|
a + b = attachement levels of total attachment loss
|
recession+ probing depth
|
|
how is the CAL calculated when gingival margin is coronal to the CEJ
|
subracting the gingival margin level from the probing depth
|
|
how to measure the attached gingiva:
|
measure from the gingival margin to mucogingival junction, take pocket depth, subratct the width of the attached gingiva
|
|
no movement
|
0 for mobility
|
|
slight mobility, up to one mm of horizontal displacement in a facial lingual direction
|
1 for mobility
|
|
moderate mobility, greater than 1 mm of horizontal displacement in a facial lingual direction
|
2 for mobility
|
|
severe mobility, more than 1 mm of movement in a facial lingual direction combined with vertical displacement
|
3 for mobility
|
|
numbers for mobility,
|
0 1 2 3

|
|
# of furcations on mandibular molars?
|
2
|
|
tip of probe can enter furcation area, roots can be felt by moving probe side to side
no changes radiographically charted by v for max and upside down v for man |
class I furcation
|
|
moderate involvement, probe can enter but doesnt pass thru, tissue fills furcation
may or may not show up on xray documented as triangle |
class II furcation
|
|
severe involvement, bone between roots is destroyed. probe can pass thru roots of furcation, no tissue recession, will show on xray tissue covers here. charted as solid triangle
|
class III furcation
|
|
same as class 2 with exposure due to recession, esp after perio surgery. no tissue covers the furcation will show on xray, charted as SOLID DIAMOND
|
class IV furcation

|
letter v

|
|
solid diamond
|
class IV furcation
|
|
which furcation involvements show up on xray
|
II (may or may not)
III IV |
|
pocket extend to or beyond the mucogingival junction
no attachment pocket extends into alveolar mucosa |
mucogingival involvement
|
|
what are some contributing facors to disease development?
|
dental factors
