All the questions have been directly picked from Carranza 11th edition
1. Not true about doxycycline
a.
recommended dosage when used as an antiinfective
agent is 100 mg bid the first day, then 100 mg once a day
b.
To reduce GI upset, 50 mg can be taken bid
c.
sub-antimicrobial dose (to inhibit collagenase),
doxycycline is recommended in a 20-mg dose twice daily
d.
all are true
ans: D
2.
Metronidazole alone is
not effective against
a.
A. actinomycetemcomitans
b.
Porphyromonas gingivalis
c.
Prevotella intermedia
d.
Treatment of ANUG
Ans: A
Hint✅ð
·
It is bactericidal to
anaerobic organisms and is believed to disrupt bacterial deoxyribonucleic acid
(DNA) synthesis in conditions with a low reduction potential.
·
Metronidazole should not
be administered as monotherapy.
·
When combined with amoxicillin
or amoxicillin–clavulanate potassium (Augmentin), metronidazole may be of value
in the management of patients with LAP or refractory periodontitis
·
Metronidazole is not the
drug of choice for treating A. actinomycetemcomitans infections.
·
metronidazole is
effective against A. actinomycetemcomitans when used in combination with other
antibiotics
·
Metronidazole is
effective against anaerobes such as Porphyromonas gingivalis and Prevotella
intermedia
3.
The only antibiotic in periodontal therapy to
which all strains of A. actinomycetemcomitans are susceptible is
a.
Clavulanic acid
b.
Cephalosporin
c.
Doxycycline
d.
Ciprofloxacin
Ans: D
Hint✅ð
Ciprofloxacin inhibit
the metabolism of theophylline, and caffeine and concurrent administration can
produce toxicity.
4.
Drugs that should not be combined to produce
desired effect
a.
Amoxicillin-clavulinic acid
b.
Amoxicillin-metronidazole
c.
Amoxicillin-Tetracycline
d.
Metronidazole-ciprofloxacin
Ans: C
· Hint✅ð
Antibiotics that are bacteriostatic (e.g., tetracycline)
generally require rapidly dividing microorganisms to be effective. They do not
function well if a bactericidal antibiotic (e.g., amoxicillin) is given
concurrently.
·
When both types of drugs are required, they are
best given serially, not in combination.
·
The most effective combination is metronidazole
conjunction with amoxicillin or Augmentin on a daily basis for 1 to 2 weeks.
5.
The use of antibiotics to treat plaque induced gingival
diseases is
a.
Done after scaling and root planing
b.
Done before scaling and root planing
c.
Done before and after scaling and root planing
d.
Contraindicated
Ans: D
· Hint✅ð
The use of antibiotics to treat gingival
diseases is contraindicated since it is a local infection that can be easily
treated with scaling and appropriate home care by the patient
6.
Local drug delivery is not preferred when
a.
probing depths greater than 5 mm with
inflammation still present after conventional therapy.
b.
multiple sites present in the same quadrant
c.
barrier membranes are placed
d.
patient is medically compromised
Ans: B
7.
2% minocycline as local delivery agent is
available as
a.
Atridox
b.
Periochip
c.
Arestin
d.
Periogard
Ans: C
Hint✅ð
·
Atridox: 10% subgingival doxycycline
·
Periochip: subgingival CHX
·
Periogard: oral rinse of CHX
