,Why do antiinfective agents play an important role in dentistry? - Correct Answer: Because infection,
after pain management, is the dental problem for which drugs are most often prescribed
What are the four type of dental infections? - Correct Answer: Caries, Periodontal disease, Localized
dental infections, and Systemic dental infections.
In the beginning, the organisms responsible for a infection are primarily what? - Correct Answer: gram-
positive cocci, such as Streptococcus viridans, or β-hemolytic streptococci
After a short time, the gram-positive infection progresses to mixed infection, which is what? - Correct
Answer: Gram-positive and gram-negative anaerobic organisms, such as Peptostreptococcus
(Peptococcus) and Bacteroides (Porphyromonas and Prevotella species).
What happens to the bacteria if the infection is left untreated? - Correct Answer: It progresses to fully
anaerobic bacteria.
The choice of antibiotics for a dental patient's infection depends on what? - Correct Answer: What type
of bacteria it is/where it is in its evolution (initial, mixed, ect.)
Define antiinfective agents: - Correct Answer: Substances that act against or destroy infections.
Define Antibacterial agents: - Correct Answer: Substances that destroy or suppress the growth or
multiplication of bacteria.
Define Antibiotic agents: - Correct Answer: Chemical substances produced by microorganisms that
have the capacity, in dilute solutions, to destroy or suppress the growth or multiplication of organisms
or prevent their action
, Define Antimicrobial agents: - Correct Answer: Substances that destroy or suppress the growth or
multiplication of microorganisms.
Define Antifungal agents: - Correct Answer: Substances that destroy or suppress the growth or
multiplication of fungi
Define Antiviral agents: - Correct Answer: Substances that destroy or suppress the growth or
multiplication of viruses.
Define Bactericidal: - Correct Answer: The ability to kill bacteria. This effect is irreversible; that is, if the
bacteria are removed from contact with the drug, they do not live
Define Bacteriostatic: - Correct Answer: The ability to inhibit or retard the multiplication or growth of
bacteria. This is a reversible process because if the bacteria are removed from contact with the agent,
they are able to grow and multiply
Factors that determine the likelihood of a microorganism causing an infection include what? (3) -
Correct Answer: •Virulence.
•Inoculum.
•Immunologic response.
Define mmunologic response. - Correct Answer: resistance of host
Define Inoculum: - Correct Answer: number of organisms present
Define Virulence: - Correct Answer: disease producing power of microorganism
What is growing the bacteria and exposing the organism to certain test antibiotics to determine
sensitivity called? - Correct Answer: Culturing and sensitivity testing
What are 3 indications for testing bacteria? - Correct Answer: •Serious infection
•Infection in a compromised patient
