perio Flashcards
periodontal ligament
support
sensory
nutritive
formative
resorption
horizontal bone loss
suprabony pocket
vertical bone loss
infrabony pocket
periodontitis associated with
P. gingivalis
T.forsythia
T.denticola
most common form of periodontal disease
plaque induced gingivitis
non dental biofilm induced gingivitis
related to the manifestion of systemic disease
necrotizing periodontal disease
related to impairment of host immune system
necrotizing stomatitis
severe inflammatory condition of periodontium
peri implant mucositis
same like gingivitis
peri implantitis
same like periodonntitis
plaque induced
main cause of periodontal disease
plaque
most significant risk factor for periodontal disease
smoking
smoking does not increase risk of caries
primary trauma on occlusion
force on healthy periodontium
secondary trauma on occlusion
force on nonhealthy periodontium
Age itself does not cause periodontal disease. It is a RISK FACTOR
bulbous
swollen gingiva
blunted
flat, does not fill interpromixal space
embrassure type
type 1: fill the interproximal space
type 2: does not fill but can use floss to clean
type 3: loss of interproximal space
pseudopocket
not true pocket
cause by the inflammation of tissue
recession
free gingival margin is APICAL to the CEJ
tooth mobility classification
class I : up to 1 mm
class II : 1-2 mm
class III : >2mm and vertical depresssionf
fremitus
visible movement of tooth when in fuction
mandibular molars
bifurcated (mesial and distal root)
furcation involvement: facial and lingual
maxillary molars
trifurcated (mesiobuccal, distobuccal and palatal)
furcation involvement : mesial, distal and facial
furcation classes
class I : can detect but no enter
class II : not completely pass thru
class III : thru and thru but not visible
class IV: visible
recession CAL
PD + GM
overgrowth tissue
PD - GM
first area to be involved with bone destruction
crest of cortical plate
appears fuzzy with disease
periodontal abcess
usually on the lateral side of the tooth
periapical abcess
apex of the tooth
lamina dura
radiopaque
tx goal
arrest the disease progression
maintain the current level is realistic goal
scaling and root planning
remove cementum or surface dentin that is rough ==> glassy smooth surface
goal of NSPT
arrest the progression
reduce pathogens
address risk factors
re-evaluation occurs
4-6 weeks
periostat
systemic delivers 20mg capsule of doxycyline
arestin
micropheres of minocycline are inserted into the pocket
DO NOT BRUSH FOR 12 HOURS AND FLOSS AT SITE FOR 10 DAYS
atridox
doxycyline gel
do not floss 7 days
NSPT recall
3 months : poor oral hygiene
6-12 months: good hygiene
ossesous / flap surgery
lift gum away to clean the root, remove disease,…etc
gum/connective tissue graft
lấy chỗ này bồi qua chỗ kia
gingival currette
remove soft tissue lining of periodontal pocket
gingivectomy
pocket reduction
gingivoplasty
reshape the ginigva
black caries classification
class I: pits and fissures
class II : proximal surfaces of posterior teeth
class III: proximal surfaces of anterior teeth
ckass IV: incisal edge of anterior teeth
class V : cervical third
class VI : incisal edges of anterior teeth or the cusp tips of posterior teeth
