plz help me with some other question

[anjali_45]

A-7 Antibiotics help to reduce pockets by
a. reattachment
b. regeneration
Choice A if antibiotics alone
A-8 in restoring a canine protected occlusion, with anterior crossbite of about 2mm, the buccal cusp of posterior teeth should be flat, BECAUSE they will guide the protrusion
a. both are true
b. only the second statement is true
c. both are false
d. only the first statement is true
i think it is c but not sure because in lingualized occlusion and or monoplane balanced with non anatmic teeth in cross bite the teeth are cuspless for crossbite ,class 2 or 3 . in this case it says only buccal is flat if it said both r flat then both r true
B-2 which of the following is LEAST useful in endo diagnosis pf children
a. percussion
b. palpation
c. electric test
d. thermal test

choice C kids can not differntiate in EPT
c-11 with mandibular bilateral extension RPD, when you place pressure on one sides the opposite side lifts and vice versa, what is the problem
a. no indirect retention used
b. rest do not fit
Choice A no indirect retention

c-12 distal palatal termination of max. complete denture base by
a. vibrating line
b. posterior palatal seal
B post palatal seal
myra i see the questions on top. i will come back and see if i can anser those questions
correct me if i am wrong
thanks

 

[sonibun]

correct me if i am wrong

200. best scale for gingival index
a. ratio
b. nominal
c. interval
ANS A(exp dont know)

203. Studer-Weber syndrome
a. mandibular retro
b. midface ecto
c. maxillary prog
is it sturger weber syndrome??what is midface ecto.

204. patient #8 and#9 PFM is little darker than adjacent teeth but is clinically acceptable, what is treatment you would propose except one
a. redo PFM
b. indirect resin bond to
c. porcelain bond to
ANS A because taht is not needed since it is acceptable clinically why tp redo when u can do patch work

211. for bevelling gingical margin, what not to use
a. hatches
b. gingival margin trimmer
c. thin taper bur
thin taper bur is the answer

243. which of the following agent is used for HIV infection
a. acyclovir
b. zidovudine
ANS b

245. which of the followin is the MOST common postoperative problem associated with mandibular sagittal split osteotomies
a. devitalization of teeth
b. nuerosensory disturbances
correct me -inf alv nerve is affected-supply teeth so
ANS a

255. an x-radiation dose of 4Gy adminstered locally to a patient's arm is MOST likely to cause
a. erythema
b. bone marow death
c. carcinoma of the skin
d. acute radiation syndrome
ANS a

256. biologic changes in the aging patient affect both pharmacokinetics and pharmacodynamics of drugs, which in turn, are manifested as each of teh folowing EXCEPT one, which one is this exception
a. decreased renal excretion
b. increase plasma protein binding
c. increased half lives of some drugs
d. decreased volume of distribution and sequestration of drug in body fat.
ANS D
i think because as renal exc decreases Inc level of drug in blood -more binding and also inc half like metabolism as there is no free drug available-check this out


293. smooth muscle relaxation is caused by which of the following drugs
a. prazocin
b. atropine
c. theophylline
d. amphetamine
theo-bronchodialator so c

314. opiod agonist act by
a. incrase pain threshold
d. acting as Mu receptor agonist
ANS d

[anjali_45]

i agree with sonibun answers too. sonibun periochip is
Another product approved by the FDA for the treatment of periodontal disease is called PerioChip®. PerioChip® is a biodegradable chip made of hydrolyzed gelatin impregnated with 2.5 mg of the antibiotic chlorhexidine gluconate. Chlorhexidine gluconate is a broad-spectrum antibiotic that kills bacteria by destroying the bacterial cell membrane resulting in cell lysis. Chlorhexidine is released from the PerioChip® in a biphasic manner with 40% being released in the first 24 hours following placement and the remaining 60% released over the following seven to 10 days. The PerioChip®, a 4 mm x 5 mm x 350 µm chip about the size of a baby's fingernail, is inserted directly into the infected periodontal pocket. Perichip® is intended to be used as an adjunct to patient periodontal treatment that includes scaling and root planing and good oral hygiene.
hope this helps
