evidence based dental care is an approach to periodontal care in which dental professionals and patients make decisions about care based on the best availableinformation. The evidence based decsion making process requires the integration of the best clinical research, practitioner experience and patient values.
Both true
At the top of the pyramid for the levels of evidence you will find
systemic reviews
in the PICO process to form an answerable question the C stands for
Comparison

d. can be used when periodontal infection is generalized or severe.
d. can be used when periodontal infection is generalized or severe.
patient with localized aggressive perio may be treated with all of the following systemic antibiotics or combinations except one
???
Erythromycin and penicillin
which systemic antibiotic is most commonly used with NUG/NUP when they have a systemic complication
metrondinazole
Host modulation therapies ususaly involve medication that can alter biochemical pathways in a manner that will
All of the above ??
Parafunctional occlusal forces are forces placed on the teeth that
result from TOOTH TO TOOTH contact other than during chewing (bruxism)
the most common clinical sign of occlusal trauma is
increase in mobility
From the information you have what do you think is causing her sensitivity in the area of #18-20
??
primary occlusal trauma
if left untreated clinical / radiographic changes that may occur with the above sensitivity in the area are
widening of the PDL, vertical bone loss and tooth mobility
All of the following are signs of occlusal trauma except one
??
periodontal pocket
When the jaw is in the most unrestrained returded anatomical and functional position pf the condyles in the gleniod fossa of the tmj and the jaws are centered without using the teeth is referred to as
centric relation
when there is a diseased periodontium first and the normal occlusal forces are applied resulting in a reduced ability of the tissues to rist occlusal forces and the signs of occlusal trauma exhibited indicate
Secondary occlusal taruma
Positive osseous architecture is when
the alveolar bone is more coronal interdentally than over the direct facial and lingual
The best surgical treatment for adequate zone of attached gingiva on the facial of #23 and 24 would be
??
connective tissue graft
of the following procedure which would entail the removal of the largest amount of soft tissue
??
gingivectomy
when using the GTR which of the following tissues do you not want to form or attach to the tooth
epithelial tissue
most healing after non surgical therapy or flap periodontal surgery occurs by a decrease in edema and then
formation of the long JE
the most important aspect of post surgical maintance care is
adequate plaque control

??
reduce pockets by apical positioning
the main difference between the (lateral positioned flap) pedicle graft and the free gingival graft is that the pedicle
