soft and spongy consistency
diseased gingiva
firm and tight
healthy gingiva`
has markings from 1-15
unc15
color coded probes are marked where?
3/6/9
what factors can influence periodontal classification?
medical conditions
restorative issues SUBGINGIVAL calc and plaque distribution
soft and spongy consistency
diseased gingiva
firm and tight
healthy gingiva`
has markings from 1-15
unc15
color coded probes are marked where?
3/6/9
what factors can influence periodontal classification?
medical conditions
restorative issues SUBGINGIVAL calc and plaque distribution
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 maxillary molars?
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
class I furcation
triangle
class II furcation involvement
solid triangle
class III furcation involvement
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
gingiva
diet, OH, and tobacco use
XEROSTOMIA
contributes to disease due to a decrease in the self cleansing mechanism
xerostomia
cause of temporary xerostomia?
dehydration, fever, uncontrolled diabetes
causes of permanet xerostomia
radiation therapy, neoplasm or brain cancer causing salivary gland removal, drug induced,
effects of xerostomia
dry mouth, mucosa may be burning and sore, redness of tissue in absence of plaque
increased plaque
dental caries, especially root surface and cervical is an effect of what?
xerostomia
treatment of xerostomia: 4
fluride gel in custom trays, saliva substitute, humidifier in home, meticulous OH
ANUG stands for?
acute necrotizing ulcerative gingivitis
what does ANUG involve?
free gingiva, gingival margin, interdental papilla
is ANUG contagious? what age does it usually occur
no, 15-30
ANUG usually starts are what?
tip of papilla
gingival absess is located wherE?
in the marginal area
located in deeper periodontal tissues, aka lateral absess
periodontal absess
