questions highlighted in lectures

Question Answer
term for loss of alveolar bone on the facial (rarely lingual) aspect of a tooth that leaves a characteristic oval, root-exposed defect from the cementoenamel junction apically.Dehiscence
term for "window" of bone loss on the facial or lingual aspect of a tooth that places the exposed root surface directly in contact with gingiva or alveolar mucosa.fenestration
alloderm (can/cannot) survive outside by itself and why?CANNOT b/c no blood supply
t/f: Alloderm is a cellular epidermal matrixFalse
T/F: Miller Classifications 1 and 2 often have inter proximal bone lossFalse
T/F: Miller Classifications 1 and 2 do not have inter proximal bone lossTrue
What is the most common etiology of gingival recession?Vigorous brushing
T/F: Dehiscence increases the likelihood of recessionTrue
T/F: retaining fat or glandular tissue improves the chances of graft successFalse (one of the criteria to not retain fat or glad tissue)

T/F: Graft donor site should be non-keratinizedFalse
T/F: Presence of a hematoma in graft site improves chance of successFalse
T/F: Presence of a hematoma in graft site undermines graft successTrue
T/F: Plasmatic circulation is early healing before capillary growth and if it is the only type of circulation established then it improves graft success rateFalse (won't work)

T/F: Higher frequency of recession and V-shaped grooves in teeth with good OHTrue (bc tooth brushing is major cause)

If you have 5 mm of gingiva and you have 1 mm of sulcus... how much is attached?4 mm
Lang's rule is ___ to ___2:1
In normal graft placement... plasmatic circulation happens for how many days?3 days (day 0-3)
Does connective tissue graft or free gingival graft have less soreness overall?Connective Tissue
What type of graft is predictable for root coverage?Connective Tissue graft
What are 3 disadvantages of Connective Tissue grafts?2 surgical sites (as opposed to 1), Technique sensitive, & Bleeding
T/F: Alloderm is an acellular dermal matrixTrue
ADM (acellular dental matrix) contains what 4 things?blood vessels, collagen, elastin, proteoglycans
T/F: Alloderm is a cellular freeze-dried matrixFalse (it is an Acellular matrix ... no cells)
Post Extraction Alveolar Bone Loss... First year ___% decrease bone width, ___ mm decrease bone height25% width; 4 mm height
major advantage of PAOO (wilckodontics)Decreased treatment time
can you do root coverage procedures with graft... augmentation... or both?BOTH
____ contraction is shrinking that happens to graft after is it cut from donor site but before placementPrimary
____ contraction is shrinking that happens to grafter after placement on recipient siteSecondary
T/F: Furcation arrows are radiographic signs usually associated with maxillary molarsTrue
T/F: Furcation arrows are radiographic signs usually associated with mandibular molarsFalse (max)
condition gingiva coronal to CEJ, and you have bone that is almost to the CEJ; whereas normally, it is 1-2 mm apical to CEJ. Gingival margin is always coronal to the CEJAltered Passive Eruption
T/F: Delayed (or altered) Passive Eruption is when the gingival margin is at the CEJFALSE
T/F: if you are going to do a gingivectomy you have to have adequate gingiva to do it. true (1 mm?)
most common bony defectCrater (aka 2 wall defect)
is a patient on coumadin with an INR of 1.5 or 2 a contraindication for perio surgery?NO it is not
is smoking an absolute contraindication for perio surgery?no (concerning, but not absolute contraindication)
is a patient with poor oral hygeine and absolute contraindication for perio surgery?YES
When do you do GI, PI, and OHI?every appt!
Bone graft--not from person, but same species is _____ALLOGRAFT.
Bone graft from cow bone is _____graftxenograft
T/F: Periodontal surgery often results in gingival recessionTrue
Which has linger root trunk... max or man molars?Maxillary molars
"restorative margins after perio surgery... how long should you wait to make an impression?6 weeks
t/f: in root coverage surgery, you may get gingival augmentationTrue
biologic width = ___ mm2.04
what is the primary etiology of periodontitis?"bugs/plaque" i.e. microbes and the immune response
t/f: increased risk for root caries is a problem associated with tunnel procedureTrue
t/f: cervical enamel projection is a contraindication for tunnel procedure treatment of root furcationFalse (not a contraindication, you would just remove in process)
new evidence showing that some of these bone substitiue alloplasts can stimulate bone formation, including new cementum with fibers. do you believe this?NO
name for treatment of enamel pearlOdontoplasty
something something using wax ups and set ups: t/f?True
what cell dominates early inflammatory stages?PMN (errr. i might think neutrophils specifically... but PMN's is a class that includes neutrophils)
grafts shrink more if they are _____thinner
Periodontal dressings are used for what 2 purposes?protect the wound and for the comfort of patient
you start getting connective tissue reattachment at _________ weeks, which is why we don't re-eval, at the earliest, until the ___th week3rd week; 4th week
when do they start measuring tensile strength after surgery?2 weeks

seibert's classification system

Question Answer
how many Seibert classes are there?3 (only 3)

Vertical bone loss (AC) A/C loss tissue, normal ridge width in F/LClass 2
combination F/L and A/C loss tissue resulting in height and width defectClass 3
memorize

phases of FGG healing

Question Answer
graft survives via avascular "plasmatic circulation" from recipient bedInitial Phase (0-3 days)
anastomoses between recipient bed w/ grafted tissue, capillary proliferation, epi proliferation from adjacent tissuesRevascularization phase (2-11 days)
number of vessels reduced, epi matures w/ formation keratin layerTissue Maturation Phase (11-42 days)
