Infection Control - FINALS

Dr. Joseph Lister (1860)

Antimicorbial chemical agents was first used in medicine and dentistry

Dr. Joseph Lister (1860)

Advocated the use of carbolic acid (a simple phenol)

1950s

Started the application of antimicrobial chemicals to the oral mucous membrane as an infection control measure

Goal in infection control

Lowering the potential for exposure by reducing the concentrations of aerosolized microorganisms

Preprocedural mouth rinse

A mouth rinse used by patients before a dental procedure, intended to produce a transient reduction in the overall numbers of microorganisms in the oral cavity.

PHENOLIC-RELATED ESSENTIAL OILS

Listerine Original

BIS-BIGUANIDES

Chlorhexidine Gluconate (CHG)

QUARTERNARY AMMONIUM COMPOUNDS

Cetylpyridinium Chloride (CPC)

OXYEGENATING AGENTS

Hepatitis

an inflammation of the liver. Often the inflammation is virally related

Hepatitis A virus and hepatitis E virus

transmitted via oral-fecal route, mainly through contaminated food and water

hepatitis B virus (HBV), hepatitis C virus (HCV), and hepatitis D virus (HDV)

are bloodborne diseases usually transmitted by direct (sexual contact, blood transfusion, blood splatter) or indirect contact with infected body fluids (used needle, dried blood on surface touched by open wound)

HEPATITIS B

The only DNA virus (double stranded) among all the others. A, C, D, and E are all RNA viruses (single stranded RNA virus).

HEPATITIS B

it has its own envelope.

Steam autoclave

heat under pressure, steam under pressure, the most effective, most economical way of sterilizing dental instruments

HEPATITIS C

is from the flaviviridae family. It is also an RNA virus, an envelope and is common in individuals undergoing hemodialysis on a regular basis.

Hepatitis B and C

when they infect you, you might actually not be able to take note of them as something that belongs to hepatitis because it will disappear for a few days or for a few weeks and you will come back to your regular healthy self not unless the virus has already damaged a big part of your liver

HEPATITIS D

-A defective virus, an RNA virus
-It will not be capable of infecting another human being except for those who are infected with HDV.

Hepatitis A

From the Picornaviridae family

Hepatitis E

from Hepeviridae family
