SPECIFIC incidence is the key
Over a period of time.
83
cross sectional?
a group of people (assumed to be cross section of total pop) are looked at and assessed at ONE TIME. Say they want to see if alcohol consumption related to cancer. They look and see who has cancer among who are and are not drinkers. TOUGH TO ESTABLISH CAUSATION. Was cancer caused by alcohol or something else.
**look at this group and try to make causation. Look at this group and say, these people drink and have cancer" etc.
84

people with the condition or CASES are compared to those without. look at some with cancer and some without and.
85
variance
standard deviation of the means

87
confouding
in epidemiology- you want to reduce those confounding variables.
88
when you want to compare 2 groups of people what do you look at?
chi squared- tells you the significance of a correlation.
89
best flap surgery of gingival recession?
lateral pedicle/
90
max depth of toothbrush and floss?
toothbrush is 1 mm, floss is 2-3
91
biologic width?
2 mm, 1 mm is the attached.
| biologic width = sulfur ep + CT
92
regenerative surgery
bone graft
93
flap surgery
for SRP
94
chlorohex?
disruption f the cell membrane
95
listerine action?
phenols and disrupts the CELL WALL
96
CHRONIC periodontitis
PORPHY gingivallis.
97
aggrieve perio?
AA
98
if greater than 2 mm sinus communication?
use gel foam, suture, decongestant and ABX.
99
if sinus communication is greater than 6 mm?
needs a buccal flap
100
periodontal pathogens in health?
gram + facultative COCCI and fialments- anaerobes
101
when is gingivectormy contrite gingival groove, or apical taindicated??
if the sulcus is APICAL to the crest of the alveolar bone.
102
internal be the ridge.of vel?
tends approximarlty from designated areas tot he crest
103
resorption of b0one is PD disease?
IL1
104
purpostion of PDLe of GTR is?
prevent the long JE migration of PDL cells
105
tx of a complicated fracture involving pulp?
vital pulp therapy if the tooth is immature
106
coronal fracture?
poor prognosis. can stabilize the coronal fragment with RIGID splint for 6-12 weeks. i fompossoite, ups can extract the coronal sgmet and then pull the apical portion up with orthodontics or periodontal surgery
107
mid root fracture
stabilize for 3 weeks. pulp necrosis happen sin 25% of the time. if pulp necrosis happens in both segment, you can remove the apical segment and then fill the coronal.
108
apical fracture?
splint. best prognosis
109
fracture prognosis
horizontal better than vertical
non displaced better
oblique is better than transverse
apical is better
110
how to treat concussion?
no treatment. ocular adjustment and then follow up
111
subluxation
splint for 1-2 weeks if it's mobile.
112
if tooth was out of mouth for less than 60
you want to keep the PDL intact, wash out the coagulum from socket with saline, reimplant, stabalize 7-10 days, abx penicillin or doxy for 7 days.
113
closed apex avulsion?
remove debris and necrotic PDL, remove coagulum pocket with saline, immerse tooth in 2.4% sodium fluoride with pH of 5.5 for 5 minutes, reimplant, stabilize for 7 days, administer systemic.
big difference is immersing in sodium fluoride.
114
IF open apex and less than 60 mins
clean root surface, place the tooth in doxycycline with saline, remove coagulum from the socket, splint, and then
IF OPEN APEX out for more than 60 mins-- implantation is not usually recommended. could start apexification perhaps?
115
when to start endo after avulation>
if closed apex, usually want to start endo at 7-10 days,
if open, try to wait for revasularazaiton, if infected pul start the apexicatlon.
116
hemisection?
for mandibular molars with buccal and lingual class II or III involvements.
117
osteogenic
ability to induce formation of a new bone
118
distal wedge procedures
FOR MAXILLARY TUBEROSITY, nadibular retromolar triangle area, distal to the last tooth. think of these as wedge site.
119
modified WIDMAN flap
facilitates instrumentation, but it does NOT reduce the pocket depth.
Decision for a Widmna flap depend son the pocket depth, and location of the mucogingival junction. need to know how much attached gingiva you have.
Use the widman flap for exposing root surfaces for removal of pocket lining. 3 horizontal incisions is used, but not reflected past the mucogingival line. reduction happens with healing of tissue.
120
undisplayed unrepositioned flap?
this one will actually remove pocket wall and eliminate the pocket. MOST frequently performed.
in the initial incision, the sort tissue pocket is removed- It's an INTERNAL BEVEL gingvectormy.
121
what two techqnies remove the pocket wall?
undisplayed and the gingivectomy
122
apically positioned flap?
this improves accessibility and eliminate pocket by apical.y positioning the soft tissue wall of the pocket so it preserves or increases the width of the attached gingiva by transforming the previously unattached keratinized pocket wall into attached tissue
123
internal bevel incision
1. removes the pocket
2. conserves the uninvolved outer surface of gingiva,
3. produces sharp, thin flap margin for adaptation to the tooth junction.
124
soft tissue graft that is rotated or repositioned to correct an adjacent defect?
pedicle graft. base of the graft remains attached to the donor site. the graft never loses it's blood supply. think of pedicle because it's still attached.
indications to widen inadequate zone of attached ignigva, to repair isolated area of gingival recession.
IF donor site does' have enough attached, or the donor site has a fenestration or dehiscence.
Pedicle grafts are not good for generalized recession cases
125
guided tissue regeneration?
placement of nonresorbable barriers or reservable membranes over a bony defect
IDEA is to prevent epithelial migration along the cement wall of the pocket. favors PDL and bone instead of epithelium during the healing?
126
laterally positioned flap variation?
double papilla flap
127
partial thickness flap-
epithelium and a layer of the underlying CT are reflected
128
4 rules for flap design
base should be wider for the blood flow.\
NO incision lines over any defect
incision that traverse a body emindense should be avoided
FLAP CORNERS should be rounded. Sharp will delay healing.
129
when is the AFP contraindicated?
if patient is at risk for root caries or if the exposure is anesthetic.
130
horizontal incission- the 3
1. internal bevel
2. crepuscular
3. interdental.
131
free mucous graft vs. free gingival graft?
free mucosal- has subepthial CT graft differs because free mucosal is T without EPITHIAL covering. So this has to come from the underlying CT. more difficult than free gingival grafting. free mucous is used on canines a lot.
132
during healing, what happens to the epithelium of the free gingival graft?
degenerates and sloughs off. Re epitheliazaiton occurs by the proliferation of epithelial cells form the adjacent tissue and the surviving basal cells of the graft tissue.
133
Full thickness flaps
result in SUPERFICIAL bone necrosis in 1-3 days! results in some loss of bone
134
reshaping the bone without removing tooth supporting bone?
osteoplastly
OsteECTOMY is removing tooth supporting bone.
135
positive and negative architqucture
positive if raducualt bone is more apical, negative if the interdental bone is more apical.
